Hi George,
You can but keep in mind the real world limitations
of the small "Flat Pack" mobile style Duplexers.
The VHF versions are not designed for Ham Radio
repeater frequency spacings. You'd be hard pressed
to get the more common surplus VHF Flat-Packs to
play at 600KHz repeater offsets unless the Duplexer
was originally designed for tight/narrow spacing.
The typical UHF versions Flat-Packs" can be specified
for and operated with 3MHz and 5MHz spacings at
honest modest power levels.
A realistic person would not expect full Spectra
Radio power levels (output) to play well with a
flat pack. So that person would probably have
to reduce/drop the transmit radio's (Tx) power to
avoid desense issues.
15 honest watts through a flat pack is a generic
realistic value, which also depends a lot on the
quality (front end) of the receiver and the Duplexer.
Of course your results will vary with cooking time...
cheers,
s.
