Re: [TenTec] DDS PTO replacement for old Ten Tec rigs

Mike, check out:

 http://qrp-labs.com/vfo.html

This one has a "clicker" but as someone mentioned here you can get one 
for a buck or two that does not click and will likely drop into the PC 
board pattern.  The price is right and although I don't have one, I do 
have it's sibling in the QRX transceiver which works like a charm (both 
VFO and transceiver)  Any time you want you can replace the low cost 
encoder with an optical encoder like on the higher end radios.
I'm thinking of using one for my Corsair II by replacing the PTO in the 
remote VFO with one of these.  Have a few other projects to complete 
first though.
