Subject: [DSP-10] OCXO ready....
Message-ID: <90.26aa02f3.2a2a4fd8@aol.com>
Hi folks....
long time ago I have been talking about the availability of surplus OCXOs
over here in Germany and Europe to gain the needed stability for the DSP-10
project.
There are none on the surplus market over here, and if, they are very
expensive. This situation brought us up to start the development of an new,
affordable OCXO in the low-price range but with all the possibilities and
specifications of the "high-society" high-priced units.
Since more then 6 weeks Walter and I have been working hard (outside our
normal daylight duty) to find an solution who is able to compete with the
specs of the OCXOs found on the market. Now we have finished the design and
have been building the first units. Lots of problems needed to be solved. One
of the biggest problem was the design of the heater. It was a nightmare, but
after all we are able to keep the temperature variation of the osc. cavity
below 0,06 degrees Celsius during an day-night cycle due to a special
oven-cavity and regulation circuit. The unit is also voltage controllable to
be steered by a GPS RX and his interface-board, like the one from Brooks
Shera, W5OJM.
Its over now and final tests have begun. The results so far are satisfy our
goals.
For those who like to see more, take a look on our European-DSP-10 website under the
button New OCXO

by DC8SW and DC9UP. (

May thanks to W7PUA and TAPR and everyone involved in the DSP-10 project!
I'm still working at assembling my kit. Everything is going well, except for the Analog Devices DSP software from their FTP site.
I cannot get Disk 1 and Disk 2 installed on any of my computers. During the install everything goes well, until I reach 86% during file copying. At that point the program says "Copying Files ezkitapp.ex$". It then asks for disk 2; but no matter what path I enter, it cannot find the file "ezkitapp.ex$". It is on the disk, so I don't know why it can't find it. At this point in the install, the only option that I have is to cancel.
Any help from the list would be greatly appreciated.
I really think that this project is great! I've been assembling it at work during my spare time, and all of my co-workers are curious as to what I am up to.
Thanks,

Hi Jim,
Here's the solution that worked for me:
>From Bob Larkin:
============================================================================
==
A couple of thoughts. To try all this out a few months ago, I got Disk1 and
Disk2 off the FTP site and was successful in installing them on a laptop. A
few minutes ago I looked at Disk2 that I had literally moved to a floppy and
noted that I had added a note file that said:
"For the install to work correctly, the "Disk 2" files need to
be located in the path A:\21xx\ezkitl\2181\
This needs to be created, most easily right on the floppy
such as is here.
============================================================================
==
Basically, if you place the disk 2 files at the above path on the A: drive
it works fine -- the install program expects them to be there and no other
path is acceptable.
Regards,
Robert

Message-ID: <20020609.234624.8219.81218@wm6.nyc.untd.com>
Hello Group,
I am in the "Power Up and Initial Testing" stage of DSP-10 assembly. My question is about the Table 1 nominal DC voltages that may be expected from a properly operating main board. My first seven voltages match those published in the October 1999 QST. My last six voltage measurements differ substantially from the measurements given in QST. My measurements are as follow:
R110, 1.8 VDC
U105 pin 3, 2.3 VDC
U106 pin 3, 3.6 VDC
R59, 1.39 VDC
U8 pin 3, 1.6 VDC
U9 pin 3, 3.2 VDC
All voltages are referenced to ground.
These measurements were taken with the DSP-10 board not connected.
Any comments would be appreciated.

Have already got the DSP from Analog Devices and the PCB from Marshell

Will consider purchasing your DSP-10 kit with PCB also if you do not want to

Hi Duncan,
Thanks for the info. I guess that explains why everyone knows and I don't!
I was sure there had to be some hardware info somewhere but I did not
recognize a users manual. It must be on the CD that I dismissed as Windows

The perfect bound users manual should have been included with your EZ-Kit Lite.

Thanks to N7HPR, W7CQ, KO7N, WB6HKA, PA0OCD and WB9OWN another DSP-10 is completed and working.
Assembly went smoothly as I followed the expanded testing notes from W7CQ and KO7N. Those notes saved me a lot of time because I did have the DAC Left and DAC Right lines reversed.
I only have a couple of comments of my own to add regarding the assembly process. Concerning the 10 MHz oscillator, I warped this onto frequency by adding a 27 pF mono ceramic cap to pins 2 and 3 of J106. I did this by simply crimping the cap into Molex terminals, along with the jumper that goes between pins 1 and 2. I did this because I was working at home during the final assembly, and I could not "borrow" any chip caps from my employer. This seems to be a satisfactory solution until I can build an accurate 10 MHz reference. The measured drift using this method was about 24 Hz in 6 hours.
I think that the alignment of L8 through L13 is easier to do by tuning for maximum power out during transmit. It seemed easier to me to peak my rf probe than to dip for a quiet signal.
I checked my DSP-10 at work on a Motorola service monitor, and it seems to work as advertised. Signals that are -152 dBm are easily seen 10 dB above the noise. 20 dB quieting is at better than .3 uV. And power out was 29 mW measured with an HP 8481H Power Sensor on an HP 435B Power Meter. Adjacent channel selectivity for FM (30 kHz spacing) was so good that it was off the scale.
I am still plagued by the 5 kHz birdies, though.
Thanks to W7PUA and TAPR.
73,
Jim Albers N9CYL

Hi,
Unfortunately, what is obvious to some isn't obvious to all. AD's PCB
layout folks are using "the square hole is pin 1 rule" for numbering the
0.1 inch connectors (well, at least on my EZ-Lite Eval board.)
