Well, I have only one observation on this statment. In late 70's or early 80's
CP was the proposed solution to ghosting. WTTV - 4 Bloomington converted to CP
for that exact reason. Working in the field we documented the difference at a
receive site. I still have the Poloraid's somewhere but

Can some one with one of those fancy programs like Comm-Shop run it and tell me
the max power a Exec II on UHF ham band run with a 75 isolation mobile
duplexer. Assuming that the coax and ant are a ideal setup.

Mike, I use a 2 watt solar powered SP-2 by PulseTech. Works great.

Vern, If your relay coil doesn't draw very much current it probably would
work. I would say using a opto isolator or minumum a transistor switch would
be a more practical method. I use a simple 2n transitor to fire a MII for
echolink.

Anyone have a copy of an older version of the code & user tables? I
have chip version rev 4.34, and the RB sites text is rev 4.7.. There
are some differences apparently and it would be nice to get the
correct tables.
Randy
I don't beleive that to be correct. The FCC has mandated 3 years for
the continued carriage of analog. Some exceptions on small systems
and low bandwidth but most will still carry analog.

Looks like you should be on 444.85. Nothing close here on that freq.
Both 12.5 up and down have repeaters closer. Cinci and Troy I beleive.

Hi, I have a slight problem with a 444.6 output repeater and looking
