what has happened to Juma Kits

Has juma kits closed down? Everything has been out of stock for a very long time. Is it possible to get the pc boards only and we can source our own parts.
We would need a source to obtain programed cpu's or pic's for the various kits.

Re: PA100D PTT Pblm

Disconnect all of the cables except for power. Try it again. Did the malfunction go away when you switch to operate?

Re: PSK on TRX1

The trx1 is a double side band rig. Please correct me if I am wrong, but I believe that you will be transmitting two PSK signals. One on the lower sideband and one on the upper side band.

Re: TRX2, align and tune up

Gone are the days of old ham radio tuning and alignment. No test equipment is needed but I do use a multimeter at times to just check the components. Alignment for the dds is all done in software.
