Hi Bob,

I have this setup. It works great--and in fact so well, it's hard to see! The "setup" didn't do anything for me unless I ran the numbers WAY off to one side or another. Then the radio acted weird--it was effectively messing up the proper oscillator freq. and sounded warbled. I've put coarse and fine in the middle of the recommended ranges and leave them there...the "tuning" is broad. Don't fret over adjusting uch here...

How can you see it working? Here's what I did--use the waterfall to watch a stable, steady signal (even a "Birdy") on 2M, on SSB. Zoom in the waterfall, so it's like +/- 2 kHz. Now, using the software for the freq. standard, toggle the reference signal ON and OFF, slowly....you should be able to see the "birdy" move just a little, back and forth as you toggle off and on. With the freq. standard "on", it's in the right calibrated place. With it OFF, it's showing you how far off freq. your radio is without correction.

Hope that's clear! I spent some time convincing myself it was working--and did what I tried to explain above. check it out, let me know how you make out.

Anyone in the US use this board (along with a GPSDO) in their 9700?

How do you know it's actually working? I have yet to be able to do their set up suggestion as described.

Always learning.....
