Does any one know or a source (other than Horizon) of JR transmitter
schematics? I need to do some fine tuning and a schematic would help. And
yes I hold a FCC First Class Radio Operators License plus have the equipment
to do it.

Thanks for a help and obtw the transmitter is on 53.1 MHz.

Glenn: I think they do not give out diagrams...I have never seen
any...even Futaba did not give out diagrams as I recall. You can talk
to Bruce (one of the good guys) at JR repair and maybe he can help
you. Some of the adjustments in the JR module are for deviation, I
think, and you want to be sure of what you are doing. Not like the
old AM stuff where you just peaked for maximum output. I am assuming
you have a spectrum analyzer. I have an old HP tha tsomebody gave me
that doesnt't work and cannot find anyone inthe HP world that can help
me with it. Looks very nice, weighs a ton and I am stuck with it...
