Hello Eric, I picked up a few ISOTEMP VCXOs from Pyro Joe on ebay. 12VDC operation
Currently using one as a 10 MHz reference for my AD6IW PLL osc for the LO on my DB6NT 10 G2. For the control voltage, I use a multi turn pot and cal at home, before the contest weekend. I am tickled with the frequency stability. I use mostly USB and CW. I packaged it up in a diecast box to keep the wind off. Plan is to expand the concept to 24, 47, and 78 GHz. If I need more frequency stability for the processing gain in a ARGO/QRSS CW mode, I can migrate to a Rb in the portable station.
