All,
Currently I have several radios which have native coverage of V/U bands, and am
looking to get rid of one or two. While I have them all, though, it seems like
a great time to do a TRUE side-by-side comparison... not an A/B switch, but
audio inputs from each rig, off a common antenna (while disabling tx of
course), such that fading or occasional reflection becomes less of an issue,
for example.
I have multi-input audio interfaces, but does anyone have an idea of how to
handle the RF side safely and with reasonable accuracy? I'm thinking along the
lines of the old FM+TV "active splitters" that had preamps, but not sure of the
quality and of course they are all tuned for 75 ohms, and while there are ways
around that, I'd rather not do a bunch of throwaway work or retune at each test
frequency.
Thoughts? Or am I thinking about this improperly?

PS: Also looking for tips on heating copper tubing to homebrew halo antennas...
the big gas torch is way too big, even the 250w soldering gun seems too
small... maybe I need a small torch? Or break out the oxy-acetylene wand? :)
