Mike;
I have looked at it, here is the dilemma. The channels are
pre-programmed into the tx and rx decks. There are rotary channel
switches to select the channel( at least in the ones I have) . Valid
channel numbers are 1-400. 401 unlocks the vco. Both tx and rx react same.
The only way I think it is going to work is if someone
engineers a micro-controller to interrupt the pll and the cpu to
modify the load data. Separate processes will be needed for the tx
and rx. The leads are relatively accessible on the platters. The PLL
chip is documented. I have some pc scope captures of the load
process. I do not have time to develop a solution..I will provide what I have if someone wants to pick up the ball. Pete N2MCI and I have both eyed this one and really just do not have the cpu cycles to spare... Doug KD8B At 08:32 PM 7/31/2007, you wrote: >Ok, Here is a good one for the group.
