[NLRS] 10Ghz weak signal source.

[Jevon (Jon) Lieberg]

Several people at the Saturday breakfast asked for info on my 10 Ghz 
weak signal source that I brought. The design came from an article in a 
CSVHFS proceedings by K2DNR. I have put the article and some pictures of 
a source I built on my web site.

  I have made some modifications to increase the output level. First I 
use a 64 Mhz crystal instead of the 32 Mhz in the article.
Then I added a MAR3 MMIC between the clock osc. and the comb generator. 
I used .001 chip caps to couple the signal in and out of the MMIC and I 
used a 150 ohm, half watt resister tied to 12vdc to power the MMIC. I 
attached a 10 Ghz feed to it to act as a filter. When I put the source a 
100 feet from my 10 Ghz rig I get about an S6 signal. The source also 
works great on 2304, 3456, and 5760 when the filter is removed. Could be 
very useful for a rover to check out if all the bands are working.
