Message-ID: <20040201065906.64013.qmail@web40703.mail.yahoo.com>

I am looking for an Alinco dx70t to take mobile and
portable with me.  I have for trade an Icom 551D
SSB/CW 100 watt radio.  Comes with mic, manual,
service manual, and power cord.  Works great, looks
OK.  This is the perfect opportunity to get a higher
power rig on 6, if anyone is looking for that.  Let me
know if you have a DX70T available.

Subject: [Alinco] DR-130T roasted RF module?
Message-ID: <17C5644C34F36B419EA8A4934B5F87AD43404F@dellserver.ad.kuhngroup.com>

I have a DR130T that has apparently roasted its' RF amp module.

A few weeks ago we had an ice storm that had all my antennas coated
solid. I assume my SWR may have skyrocketed at times.

It's kind of odd - Now whether the radio is in low or high RF setting it
draws under 3A (my DC supply has an accurate ammeter). The built-in RF
meter still indicates a low power output on LOW, and a high output on
high. It does this on my antenna and on my dummy load. On-air testing
shows no signal difference between power levels at all.

I would have thought that if the RF module roasted I would have no RF,
not just be stuck in low..?

This radio always drew right at 10A before this happened.=20

Anyone know if this is typical of a toasted RF module?

If it is, then my next email will be looking for a cheap DR130T that I
can pull the amp out of..

It makes sense that the low power RF is probably the drive for the power
amp. It just seems odd to me that with a dead RF module the input power
still passes through apparently quite well as I still have good tx
range. I would have expected a short or open..?

Oh well.=20

I did check RFPARTS, and the module is about $53.=20

I figure I can pick up another used radio with equal or better
capabilities for not much more $$, but I like my 130. I have the memory
expansion in it for 100 channels and it does great for my VHF needs
until I stumble upon some great all-mode VHF deal.

First I'm going to check and see if anyone has another DR130 they'd like
to unload cheap. I don't care if it is working or not as long as it has
a working RF amp..

Anyone have a DR130 they want to part with cheap?? Radio doesn't have to
work or look good - I just want a working RF module!

Bill...

I'm not familiar with this particular model, but on a Kenwood I had a
similar
problem.  For low power, they just took the input to the final amp and
sent it to the
output.  For high power, they sent the same signal thru the final amp
and then to the
output for high power.  Take a look at : http://www.rfparts.com/ for a
replacement
module.  I've had good luck dealing there, and you may find your module
at an
attractive price.

Bill,

Yes, you probably have a toasted RF PA module.  Both the DR-119T and the
DR-130T radios use the S-AV17 PA module, which costs about $55 from RF
Parts.  But, before you replace the module, check to see that the driver
stage is providing a signal to the module.  You can download the DR-130T
service manual at:

http://www.alinco.com/pdf.files/Service/dr130ser.pdf

These modules have absolutely no protection from impedance mismatches
and high SWR, and they are notorious for erratic source impedance. 
Ironically, they are more likely to fail when operated at low power
levels since an insufficient drive level causes the module to fall out
of Class C operation, greatly reducing its efficiency.  An impedance
matcher installed as close to the radio as possible will improve the
match between the PA and the antenna.  Depending upon the drive level,
the PA's source impedance is probably far from 50 ohms.

I had been wondering if these had any protection from antenna mismatch
or not. I guess I found out the hard (and dumb) way.=20

My homebrew copper pipe dipole had nice low SWR when we put it up, but
I'm sure that wasn't the case when it had almost half an inch of ice on
it for a couple of weeks.

I guess I really ought to quit being so cheap and invest in a VHF
watt/SWR meter so I have a clue what is going on out there..

My DR 610 seems to be in a Channel Display Mode ala the DR 605 except
there is do documentation of such a mode. 

The Channel Number is displayed instead a frequency and none of the
other buttons or the function key seems to work. Only the H/M/L
button seems to function appropriately.

Any ideas?

Loren,

Nope, but the DR-605 does so.
