I was wanting to listen to VHF/UHF SSB. All of my present UHF/VHF
radios are FM. I was thinking of rigging up a simple downconverter
using a mini circuit mixer and my HP signal generator as the local
oscilator that I can connect in front of my HF rig. I have an antenna
mounted pre- amp that I think should suffice for my front end. Any
foreseeable problems short of keying my transmitter while it is
connected.

Do let us know what you tried, and how it worked.

UPS delivered the mixer yesterday evening but I didnt get to play with
it until this AM.Im working evenings. I spent about an hour getting it
connected up. There may not have been any SSB activity but I was able to
hear all the usual local 2m repeaters using my HF rig set up for 10M FM..

Setup was as about as simple as it gets. With pre- amp at the antenna,
antenna , receiver and osc was just connected directly to the mixer with
some small coax alleged to be 50 ohms. At this thime I really cant
evaluate it more than that.

The bands always go dead right when you finish a radio.

Keep us posted.

Seems to be overloading a little on strong signals. This is probably
the reason rreal receivers arent quite so simple.
