font-family:Arial'>Can a duplexer/diplexer be built (or is one available) that
would allow both radio systems to be hooked up to one dual-band antenna? The
dual-band radios with one antenna lead has a built-in duplexer. Is that where
the problem would occur trying to coordinate another duplexer?<o:p></o:p></span></font></p>

for voice, most likely in cross-band repeat mode on occasion, while being able
to run the APRS/packet radio at the same time being able to receive on VHF/UHF
