I was responding to a comment about the two antenna connectors being
designed for separate HF and VHF bands. That misconception about the
M802 has been corrected. The ports on the diplexers I listed are band
isolated so if you did connect it to the M802 it wouldn't work
properly but would not "blow the DSC receiver's front end". You
should stop and think before you fuss.
If we are helping the "average boater", who is not an electronics person,
any response to this thread about diplexers may lead him astray to putting
a diplexer in his antenna line, as this thread had nothing, whatsoever, to
do with VHF or AM/FM radio or diplexers.
I'd just hate to see him try a diplexer to such a nice radio as the M802,
in spite of the M802's shortcomings of the wide open cabinet with the
internal cooling fan sucking sea air into the circuits, a really stupid
design with its chinzy cable connectors, to boot.
He was looking for "the easy way out", some method of connecting those two
tempting connectors together to one cable....a path YOU were providing him
with I pray he ignores...
I don't even want him to put up a receiving antenna anywhere near the
transmitter's antenna for fear of taking out the DSC front end, which is
broad tuned for the whole HF band.
