Bob,
That is good news. I thought your 8 can set would tune up much better
than the 6 can set I did. I had to mount the one I did on it's side
also. I just got a piece of angle aluminum from the scrap pile and
made a rack mount for the duplexer, so that it laid in the rack
horizontally. I have

Duplexer of choice for me is the Sinclair Q2330E. I have had very good
results with these on our 75 Watt VHF Micor stations and we use a Angle
Linear preamp on the receivers.
In your situation where you have a brand new Telewave, I would be
tempted to call up Telewave and order 2 more
I should have thought what ever fills the gap ?

Gary,
When selecting a duplexer you want a model that is speced for the same TX -
RX spacing as the application or less. Operating a 500K spacing duplexer at
600K is not a problem but trying to get a 1M spaced duplexer to operate at
600K will be. The issue is the way the individual
First load your repeater ID into one of the blank voice message slots. Then
prigram a schedular to make the controller ID every 15 minutes or what ever
time is needed as required to ID the repeater when not in use.

If the duplexer was supplied from Telewave on 2M, then what you have is
right. LEAVE

Does the amount of power output make a difference with isolation? The
paperwork I got shows 82.3 isolation on RX and 81.5 on TX. It appears

Gary,
I think you're on the ragged edge of duplexer performance. According to the
calculation of CommShop for Windows, your power output of 25 watts, 145.450
MHz TX and 144.850 MHz RX, and assuming a 0.3 uV receive sensitivity at 12
dB SINAD, a duplexer requires 85.6 dB of isolation for no
Sorry had to rant there -- hopefully that's on-topic enough for RB...
about repeaters, but not really about building them... unless you
consider that they're often the place where the local ham community
gets built these days...
