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.

Direct from Mini Circuits
http://www.minicircuits.com/cgi-bin/...rch_type=model
or Downeast Microwave in the "components" section
http://www.downeastmicrowave.com/cat-frame.htm

Minicircuits is $7.50 each, Downeast is $18 each. I assume both will
have a shipping charge.

Thanks I was under the impression the minicircuits has a minimum
order.

Not that I'm aware of :) I've ordered small quantities from them in the
past....

"Lucky" depends on how many locals there are ;) If you have 10 or 20
local weak signal VHFers, it could get a bit messy ;)

Around here, it was in fact lucky.....

Yes, the bands were kinda flat. Plus, we had RAIN on Saturday and wet
snow on Sunday here in WI (which REALLY sucks)...Sunday brought high SWR
on the 6M antenna so I couldn't use it and didn't hear a peep on 2M.
And with the crummy precip, I had no desire to rove or set up the
portable antennas on 222, 432, 902 or 10 GHz....

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 alledged 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.
