With all of this discussion, is either the Q202 or its cousins or the new Q2330 all with now 80 dB of isolation good enough for a 2 meter repeater with a 0.6 MHz split? Putting a new machine on the air and need to know if I should go with a 6 cavity duplexer to give me the 100 or so dB isolation, and albeit the higher insertion loss or can I stay with a 4 can duplexer with typically 85 dB isolation and 1.5 dB insertion loss?
In a quandry... most of my experience is with a Sinclair hybrid ring duplexer which seems to work fine at a 25 watt level. 73 Dave WB2FTX ----- Original Message ----- From: John J.

The original literature that I had claimed 100 Db. 73 John VE3AMZ ------------------------------------------------------------------------------ No virus found in this incoming message.
