Subject: [MRCA] Providing 5 MHz
Message-ID: <DM8P220MB0472883F64231CB303CDCAECB8DBA@DM8P220MB0472.NAMP220.PROD.OUTLOOK.COM>

Use to be if you were accurate within one or two kHz everything was good, but lately been doing more and more stuff for others and now people want accuracy within Hz. Doing WJ receivers or just about any modern SSB radio this becomes more and more relevant. Have test equipment, signal generators and the like and would often just calibrate them by zero beating them with WWV and that's gets you fairly close but got tired of dealing with some people who when a question about accuracy comes up would be adamant how I must be wrong because their new Yahoowood Fangfang that they just purchased has to be correct because its new and everyone else in the Ham club has one and agrees that it's the best technology out there after you master the menus.
With that in mind I purchased a GPS disciplined 10 MHz oscillator a couple years back and feed that into a distribution amplifier to all the test equipment that has 10 MHz inputs. That gives an accuracy of around a couple Hertz to all that gear. The problem is that a lot of my older HP test equipment and almost everything that I have built by Harris wants a 5 MHz reference including my HP-8640 that's the go to generator for working with HF radios. Things like the modern synthesized Motorola Service monitor work there but the phase noise sucks when you are dealing with SSB radios.
Because of all this I decided the thing to do was put together something with a minimum of parts to divide 10 MHz down to 5 MHz
Growing up in the seventies and learning TTL I figured the 7474 was the answer, a dual D Flip Flop. Attached is a schematic of what I built up that has four parts. Part one is the input transistor to drive the clock input of the flip flop. Part two is the divide by two function, and part four is an emitter follower to drive a low impedance output. Part three is the tricky one, the intent is to try to convert the square wave output of the divider to a sine wave thru a RC circuit. If I were smart would have used a coil in place of the one hundred Ohm resistor to build a resonate 5 MHz network but not that smart.
Anyway, put this together and now the 8640 tracks along with the Motorola junk and Agilent analyzer. Next step is another distribution analyzer and syncing up the Harris R-2368 and 1310 exciter.

Included MRCA in the response being they also have a interest in such things. We have done 5357 USB on Fridays before and maybe again Friday afternoon for this year's upcoming. Also played around with 144.25 AM too. The issue now is that between the 3885 WW2 net at noon and the 51.0 Cold War net at two and the Hamvention not a lot of time left on Saturday for another net so maybe try doing the other things on Friday maybe around three or four after everyone's done there buying and selling?
5357 (USB) has a lot of opportunity being many of us already have backpack sets on that channel from M&S and other events. Maybe a brag net on 5357 at four or five each day including Thursday to talk about what we found and bough?

There is also a Pack net on Saturday on 18.1575

Already looking forward to this year's event.

Good morning.  I was thinking about this year at Dayton. Would there be interesy in activating both 60m as well as 23cm? We most all have equipment we use on 3.885 as well as 51mc. It would be interesting to include the 5mc band as well as the 220 mhz band. I know there has to be one or two PRC-41's still working as well as many of the newer AM Mil-Com aircraft band radios. Please reply with thoughts and comments.

All the best & keep well.

That is very good. I guess I should really try a loop.  I had an ARC loop that worked well. I have  a complete Bendix ADF-T12C ADF,  in the box. .  Maybe fire it up?

Lot of us have stuff for sixty meters, PRC-74 and 70 sets along with all the bigger stuff like the PRC-47 that can be dragged out into the field. Every year we do a field exercise up in Gilbert PA that's centered around people running different backpack and mobile military radios on 5357 and am always amazed by  how many people back at there home QTH can take part and work the portables.
Maybe we can do a close of the day brag net on Thursday and Friday?
On Friday and Saturday they shut down the Flea market at five and start pushing everyone off site before six but think if we did the net at five that will still give us plenty of time.

Lot of us are selling in the 77 and 38 hundreds neighborhoods, did not think about those without spaces! As always I will be there in 7739 and usually have radios set up in the 7740 ? 42 MMRCG pavilion, and we always have some spare backpacks for visitors to use. Imagine the parking lot would work also along with any distant stations. Biggest issue with 5357 is that when the sun goes down and the band opens long the digital crap takes over.

My antenna is a MiniWhip (E Field probe).  It fits in the palm of my hand.
  I have it in a weather proof enclosure at a height of 16 feet on a
fiberglass mast about 80 feet from the house.  The 75 ohm coax is grounded
at the fiberglass mast base as well as the entry point to the house.
Inside I have a hombrew common mode choke that gives me about 5K at 400 KC.


In the past I?ve run active loops and they worked ok.  Also used my 160M
inverted-L in the past.

PanAm established a resort at Rock Sound way back, hence the presence, thereof. My last time there was in maybe 1982. Pan AM had sold the property.   Governor's Harbour was our destination. I miss those days... Nice route from PBI.

?I recall that while passing through the Rock Sound Bahamas airport on Eleuthera  back in the 90s, while waiting in line to clear customs, standing next to an ancient looking NDB transmitter which was actively banging away its callsign, which I recall at the time was RSD.  Label plate on the transmitter said Property of Pan American Airways, probably was installed back in the 1930s when Pan Am initiated Clipper seaplane service to Rock Sound, one of their earliest destinations out of Miami. Apparently the Rock Sound NDB has gone dark, as there is no reference to it on the current Rock Sound Airport information online That airport?s designator is now MYER, some references list both MYER and RSD.  Wouldn?t be surprised if the transmitter is still there though!

The Rock Sound NDB.....    would that have been ZGB 224 KC on Governors
Harbor (Eleuthera)?

If so, it hasn't been heard since 1997 !

I remember the day, very well!  My wife was in S?o Paulo waiting for a flight to Santiago. Chile. PA flight cancelled and, owing to the fact she was non-rev, no assistance. At the last second, she got re-booked on Varig. AL got her back to BAL.

We like to see our electronics and do signal processing between the ears, not on silicon.

I was going through some Nautical Charts and found one form 1960 for the CONSOLAN system . The local station was TUK 192kHz Nantucket. I found an article about it and appreciated the way the author used mil surplus BC-1206 on his boat to receive the signal. See attached and enjoy.

It had been in operation forever; he tells me that in the brick shack it was located in that there were the remnants of the old open wire feeding system but all that was replaced years ago by a solid-state transmitter with coaxial feed lines. About a year after that he pulled most of the analog VHF/UHF AM stuff from the tower after replacing it all with digital secure stuff. It?s amazing how fast that old technology disappears after being in operation for so long, figure the original NBD may have first gone on the air in the early thirties. I was somewhat sad to think of it gone, he was glad to see it go and no longer having to be responsible for something no one used.

When I started working years ago, we repaired things, now almost all I do is replace technology that goes obsolete years before it fails. I have removed and scraped many television transmitters and at school we regularly send functional working Macs and PC to recycling because they won?t accommodate the latest operating system.

Several NDB Stations are coming in pretty good here in Chickenland using 
my Bendix 555 Navigator and its loop? antenna barefoot. I moved my 
portable listening post? approx 30 yards away from my buried power line 
and got a reduction of noise of 3 to 4? S units (4X6 =24 db). Its 
amazing what a little distance will do to get away from the 
interference.? Inverse-square law?
I have two types of garbage cans - Green for yard waste and black for 
standard garbage.? The Green appears to provide the best reception.

Gene/et al,/

That's not the way I read it.? Looks like our 5357 carrier channel has 
disappeared into the new low-power sub band.
Here's what's left of the previous 5 channels:

This may be the year of change! Kind of like the idea of limiting 5357 to just 15 watts for field exercises but its a real issue for any distant stations. But then again looking at the new channel layout see a group of good new channels we can use for field and remote work on sixty. I only have one radio that is rock bound for sixty and think this is a good reason to install one of those little VXO devices.
Maybe time to consider also moving the Saturday morning forty meter USB net to 7.280 to get away from the issues with some of the AM stations? Or something different? Think the QRP SSB calling channel for forty may be 7.285 but not certain. Just know that lately there have been a lot of AM QSO on 7.29 and 7.295

Yeah, we will be stuck QRP on 5357, but on the bright side, there is 15 Khz to play with. The rule doesn't become effective for 30 days past Dec 10th anyway and from what I am hearing, there is an effort to appeal for the ERP to be raised for this new segment.  Hang tight!

I decided to look at Al Klase' posting about the Moose and Squirrel Net and noticed he recommended the other channels as an alternate. During some events 5371.5 KHz was used and they vacated 5403.5 KHz (Channel 5) which is the designated 60-meter calling frequency:  

https://www.mrca.ar88.net/Old%20Pages/Net/MandS.html

Maybe we could QSY to 5371.5 in the future.

I don't know when the rules take effect but in the past they took effect when entered into the Congressional record.

Let's discuss during today's and Saturday's net.

Remember who we are brother! Many military radios like the PRC-47, 70, 74 the GRC-106 and the ARC-38A are USB only and most only move in 1 kHz steps.  Its true that a lot of the newer stuff will move in 100 Hz steps and do both USB/LSB but to exclude all the above would be to transition away from what the nets all about.
I have been working on a PRC-47 and although the PRC-47 has never been a favorite of mine it is a serviceable military radio that will provide a hands on experience of using that technology. If you cant have fun in the field running the 47 you need to be in some other aspect of the hobby. Although I did do the "clarifier" option to give the ability to QSY up and down a bit  I will not do the LSB modification because it changes the basic nature of what the radio is. If your going to run a PRC-47 you are doing it for the experience, the feel, a tribute to the technology of the period. If you convert it to LSB you are in attempt to build a Ham transceiver and that's what I am not about. The 47 can be used on sixty meters voice all day long, it can work forty and eighty meters CW just as well but if you want something just to go into the field and operate "Parks on the air " go and buy a G90
I know this has little to do with the subject at hand but for me I think whatever solution we settle on has to have some base requirements

I decided to look at Al Klase' posting about the Moose and Squirrel Net and
noticed he recommended the other channels as an alternate. During some
events 5371.5 KHz was used and they vacated 5403.5 KHz (Channel 5) which is
the designated 60-meter calling frequency:

https://www.mrca.ar88.net/Old%20Pages/Net/MandS.html

Maybe we could QSY to 5371.5 in the future.

I don't know when the rules take effect but in the past they took effect
when entered into the Congressional record.

Let's discuss during today's and Saturday's net.

I don't know about the MMRCG net but the Moose and Squirrel Net is an "on-patrol" and and Military Radios are optional. I have military radios but appreciate the idea portable operation on the M&S net. I can't haul out a military radio to the field and operate my FT-857 or "PRC" G90 depending on conditions. I've operated about 50 times portable this year on the net and only seldom hear portable military radios.

The most 60 meter on patrol operation I've heard this year was at Gilbert and two or three users were using G90's.

Good luck with the ">First USB >Second 2 to 12 MHz >Third 1 kHz steps"
Rule but keep in mind 40 meters was narrow band when I started 50 years ago and just results in fights between the USB and AM users. I wish some of the underutilized 8Mhz Marine Band channels were allocated to Hams.

Gang,

Let me say this about that.

When I set up Moose & Squirrel, I chose 60-meters because it was a good 
daytime band, and the suggested mode was USB, making it friendly to our 
old military radios that only do USB.? Further, Channel 3, unlike the 
other 4 channels, is centered on a 0.5 KHz freq. so the carrier is 
5357.0, again friendly to the old sets.



60 really is the best band for us.? If we run USB on 40, there are lots 
of idiots who will complain.

I'm going to leave it up to the current M&S participants to decide what 
to do.

73,
AL? a.k.a. Fearless Leader

Even if they increase power 5357 is the de-facto FT8 frequency. I can hear the stations during the day in winter.

If we decide to stay on a 1kHz frequency was may have to consider another frequency such as 5360. 

I've had QSO's with a Ham in Denmark. I will send him and email and see if there are segments for various modes such as CW, Digital and SSB on the 5351.5 - 5366.5 band.

I searched around and could not find any information. I did find out Somalia allows 3000 watts on Amateur Radio bands.

Remember who we are brother! Many military radios like the PRC-47, 70, 74
the GRC-106 and the ARC-38A are USB only and most only move in 1 kHz steps.
Its true that a lot of the newer stuff will move in 100 Hz steps and do both
USB/LSB but to exclude all the above would be to transition away from what
the nets all about.
I have been working on a PRC-47 and although the PRC-47 has never been a
favorite of mine it is a serviceable military radio that will provide a
hands on experience of using that technology. If you cant have fun in the
field running the 47 you need to be in some other aspect of the hobby.
Although I did do the "clarifier" option to give the ability to QSY up and
down a bit? I will not do the LSB modification because it changes the basic
nature of what the radio is. If your going to run a PRC-47 you are doing it
for the experience, the feel, a tribute to the technology of the period. If
you convert it to LSB you are in attempt to build a Ham transceiver and
that's what I am not about. The 47 can be used on sixty meters voice all day
long, it can work forty and eighty meters CW just as well but if you want
something just to go into the field and operate "Parks on the air " go and
buy a G90 I know this has little to do with the subject at hand but for me I
think whatever solution we settle on has to have some base requirements

First USB
Second 2 to 12 MHz
Third? 1 kHz steps

I decided to look at Al Klase' posting about the Moose and Squirrel Net and
noticed he recommended the other channels as an alternate. During some
events 5371.5 KHz was used and they vacated 5403.5 KHz (Channel 5) which is
the designated 60-meter calling frequency:

https://www.mrca.ar88.net/Old%20Pages/Net/MandS.html

Maybe we could QSY to 5371.5 in the future.

I don't know when the rules take effect but in the past they took effect
when entered into the Congressional record.

Let's discuss during today's and Saturday's net.

Several have asked for details on the rotatable loop on my Bendix 555 
receiver.
Attached is a photo. You can estimate the turns etc. Note the use of a 
standard phone jack for the mount. The loop is shielded. I've posted in 
the past construction details for a loop for 80 meters. I've enjoyed the 
Bendix, it has a S meter, BFO, and a "Sense" antenna.

Hi All,
It seems y'all are stuck between a rock and a hard place.
Pay attention to the image that Fearless Leader shared.  Note that it is
dated 2007, the dead bottom of the sunspot cycle.
These days optimal NVIS frequency exceeds 10MHz on the regular.
At noon, 7MHz is really much better propagation-wise than 5MHz, but has the
USB problem.
Shifting in time might be the way to make 5MHz viable.
I understand DX QRM turns into an issue in the evening.
Maybe that QRM factor is better in the just post-sunrise period when there
is a brief window of good NVIS on 5MHz.
Remember that quaint phrase, "Improvise, ADAPT, Overcome"?
73,
RF

But then again looking at the new channel layout see a group of good new channels we can use for field and remote work on sixty. I only have one radio that is rock bound for sixty and think this is a good reason to install one of those little VXO devices.

Think the QRP SSB calling channel for forty may be 7.285 but not certain. Just know that lately there have been a lot of AM QSO on 7.29 and 7.295

Rob,

You bring up a good point. Years ago I could log in with the 20 watt G90
but these days I have to use the FT-857 which required carrying a larger battery.

Last summer we did test around 7262 LSB right after the net and conditions were better.

In any case we have 30 days from December 10 to decide what to do and we started discussing it on yesterday's net and will continue the discussion on Saturday's net.

Seen them on Ebay pretty cheap.  Going to connect up my Bendix aircraft ADF  with the loop and sense antennas. Maybe I will hear something usable.

The 18S4 is in some ways a bit of a Dog being it requires separate tuned networks for each channel, a strange almost never available antenna tuner and has a broad IF Please excuse me for suggesting but think you would be happier running something like a Collins 618S1 being that gives you 100 watts of plate modulated AM, requires no special tuning networks other then crystals, uses the standard 180L antenna tuners that are all around and has a mechanical filter in the IF that helps in reception, at least on AM.
I have done all three, the ARC-38/RT-311, 618S1 and ARC-38A and unless you got to have a 18S4 I think that?s the way to go, but that?s just me.
Additionally I know someone who has been trying to sell a 618S1 and may be willing to deal.

The 18S4 is in some ways a bit of a Dog being it requires separate tuned networks for each channel, a strange almost never available antenna tuner and has a broad IF Please excuse me for suggesting but think you would be happier running something like a Collins 618S1 being that gives you 100 watts of plate modulated AM, requires no special tuning networks other then crystals, uses the standard 180L antenna tuners that are all around and has a mechanical filter in the IF that helps in reception, at least on AM.
I have done all three, the ARC-38/RT-311, 618S1 and ARC-38A and unless you got to have a 18S4 I think that?s the way to go, but that?s just me.
Additionally I know someone who has been trying to sell a 618S1 and may be willing to deal.

Hello everyone,
   I have been looking into obtaining this radio along with the remote control.  It looks like a nice radio project.
   What are opinions on the ease of repair and ease of setting it up as well as operation.  I know I would be building a power supply for it.
   The other question is if anyone has one they want to sell or trade?

Thanks, Paul WA3GFZ

As long as you are confined to a few discrete channels, it is a very good, reliable performer on AM. I have one on 3885/3855.  It is a bit tedious to set up the channels, and will require crystal(s), caps, etc. to do so, however.  It is also advantageous to have the rack, which incorporates a dropping resistor.

The 18S-1 and 4 were widely used back in the seventies on shrimp boats operating in the gulf.  According to Lloyd Godsey (SK), procured them from airlines that were upgrading to SSB, installed and maintained them.

I would perhaps instead look for an ARC-38, no crystals needed!

Subject: [MRCA] Recieve antenna on Noisy Band
Message-ID: <883437827.19751.1765909472775@connect.xfinity.com>

During the winter I operate the Moose and Squirrel from home. Sixty meter noise levels are quite high at noon. I am also usually the southernmost station and sometimes the northernmost stations are occasionally weak.

I have three antennas, an Inverted L against 35 radials that I can tune from 160 to 20 meters. I have a low 80 meter Inverted V that I can tune from 80 through 20 but is does not get out as well as my Inverted L. I also have a 20 meter vertical loop I can tune from 20 to 6 meters.

I recently rearranged my shack  so that I can easily switch antennas. 

During today's M&S net the band was moderately noisy but I could barely hear KW1I the net controller. During receive I switched antennas as found whereas the receive signal was slightly lower the noise level was dramatically lower hence the readability significantly increase since the signal to noise ratio increased. I took pictures of on 7300 spectrum scope to show the difference. See attachments.

I suggest trying other antennas to impreove the signal to noise ratio. Just remember to switch back when transmitting.

I just put up a video on the AN/PRC-47 that includes the Synthesizer offset and VOX modifications, don't know why but most PRC-47 radios were modified by Collins for just VOX operation only. Makes it good maybe for fast CW but leaves a lot to be desired on voice or super slow CW. No idea why they did a PTT line that allows normal PTT operation on the radio but never connect it to J2 pin 11, maybe it was left up to unit configuration? Who knows. Have seen no documentation to support why they did it that way other than being Collins. The Synthesizer offset is biased on the "K4CHE" design with a couple small changes.

Logged NDB #100 tonight at 0652Z:  AI 394 Kc.

AI Is the Outer Marker for the LOC/ILS Runway 30 Approach for Anderson IN
Regional airport.

Several weeks ago I stopped using any outboard audio processing... just to
make it more fun.

Your description of the RPM of the SAQ Alexandersonalternator rotation speed reflects a fundamental misunderstandingof the principles of operation of the Alexanderson alternator. 
The motor in the SAQ? Alexanderson alternator operates at 720 RPMwhich then feeds a speed increaser gearbox that increases the RPMfeeding to rotor to 2700 RPM. The operating frequency feeding theantenna is the product of 2700 RPM rotator rotation speed andthe number of magnetic poles in the rotor.
The rotor has no conductive windings or electrical connections;it consists of a solid disc of high tensile strength magnetic steel,with narrow slots cut in its circumference to create a series ofnarrow "teeth" that function as magnetic poles.
This is an excellent technical description of the Alexandersonalternator.

This is a superb video of the very complex processof preparing the SAQ alternator for on the air transmission.

Tried from home using my RAK-8 Navy  TRF Autodyne Regen.  Very hot and selective receiver however noise floor in neighborhood with overhead utilities simply too high.  Will try to get the RAK out to a quiet location like I have done  with my Wandell und Goltermann AT-611 selective level meter and had very solid copy on SAQ as long as storm related static was low.

Hi Steve

There are only two active beacons in PA:    MD 204 in Harrisburg and BZJ
328 at Fort Indiantown Gap.

I believe you are referring to ORJ (not ORG) on 258 Kc.   It was last heard
in 2015 and was decommissioned in April 2020.

Conditions sucked! The band was alright. About ten minutes before the top of the hour did hear some AM Gas bags on 7290 but that's cool but also a couple of AM stations trying to set up a QSO on 7295. Listend to 7280 and there was a QSO on LSB down at 7273 or so and occasional noise on 7280 including a LSB station for a couple before the top of the hour but then when KB4HG came up started hearing someone tuning up right on channel and then I think some AM stations started up around 7282, maybe 85 so with all that crap going on did not try. But KB4HG and a couple others were there.
Maybe better luck next week? Just want to know where all this "lack of activity" on the Ham bands is?

Well, conditions were less than ideal here in Ohio. Went to 7.280 and was able to hear KA3EKH, KW1I and KB4HG. Unfortunately they were unable to hear me on the mighty PRC-47. Maybe next week.

Message-ID: <CABdVoaD=rk_n8d_BSU-PGTRY77ZXY-_XzDS2u4bkLJXHYnokvA@mail.gmail.com>

Hi Everyone

As some of you know, I'm using my BC-453B LF/MF receiver to see how many
NDBs I can log this season ? I'm up to 123.

I don't want to use modern post audio processing (my own self imposed
limitation) and I remembered I have an FL-8-A filter on the shelf.    Since
that was used doing WW II I decided it was fair game for
audio post processing

So, I hooked it up and gave it a whirl.   ?Both? worked fine,   ?Voice? was
OK, but I needed to increase the audio,  and ?Range? seemed dead.... but I
found if I cranked up the audio to max I could hear strong signals.

Hmmm.   After thinking about this a few minutes, I wondered if I had not
taken impedance into consideration.   So, I went to K4CHE's web site where
he has some excellent info on the FL-8 posted.... and yep,  I had some
nasty impedance mismatches and I could see why the ?Range? position acted
like it did.   The FL-8 needs 8K on input and output.

All my SCR-274N radios are configured for ?low? impedance ? 600 ohms.   I
send the audio output to a 600 to 8 ohm transformer then to my 8 ohm
headphones.   Well,  I plugged the FL-8 into the 8 ohm output.... and
thence was the problem.

Handling the impedance issue is not a problem, but I have a question of
they did it ?back then?.

All of the SCR-274N receivers I have are all configured for low impedance
(600 ohms).   The receiver output on the planes had to eventually make it
headphones, and I assume the headphones were all high impedance (8K or
more) which matches the FL-8 output.

But the FL-8 input was also 8K.   That means all the receivers needed to be
configured for high impedance output (8K),  or if configured for low
impedance (600 ohms) there needed to be another box or boxes between the
receiver output and the FL-8 input.  What where those boxes?

Or... were most receivers configured for Hi-Z and all of mine just happened
to be configured for Lo-Z (perhaps by a secondary non military user) ?
