V12 RF Board


 

I see lots of test points on the RF board, is there a list of expected voltages and signal data for each point somewhere?
Trying to trouble shoot my RF board issues.

That is on the “TO DO” list.? Since this is an open/ community project… I would ask that someone with a working radio… please step up… do this as a contribution to the project if… people want it in the short term. ??I know there are guys on channel that did this for a living… that could bang it out in about 10 minutes.

My bad I had left off Jumpers 18 and 19. I can now rx fine, but only for short period then it shuts down.
Not up long enough to do RX calibration.?

Hey Tim… when you say it shuts down… what do you mean?? The signal stops or the power goes off?

Yes I have a couple hundred of the off-set boards.? They are $0.50 plus shipping and can ship in a regular first class envelope for a couple of stamps.
