Sencore VA-62

Wow! That was obviously an expensive piece back in the early 80's. I bet with a little program hack and a new eprom burnt, one could have that thing singing down in the 20Mc band. But don't ask me how. I always though some of their 60-70's gear was made sort of on the cheap, but this thing looks first class, fiberglass pcb's and all.

It might be easier than that. Assuming this uses a PLL, there should be a hi-speed digital divider in the feedback loop. Something like ÷ 256.

Perhaps that could be tweaked to ÷128, so it would put out a frequency 1/2 of what the display shows. 22 MHz instead of 44 MHz for example. Then add a range switch so it could do 17.5 - 25 Mhz or 35 - 50MHz.

You're probably onto something there. The schematic should reveal if it's divide by 256.

There has been some some progress made on this front. I'll know for sure in a few days...
