Greetings, all.
I'm putting up a 900 MHz repeater. Had a site lined up, but things
have gone South.
So, starting from scratch: How do you choose a site? How do you locate
a commercial or government tower's owners and pitch your proposal?
Appreciate any advice.

Hello,
Can you program the GR1225 out of band at 442.700mhz?

Matt,
Which way do you want to tilt it? To compensate for cable that precedes
it?
Does it have to be for 50 ohms, or will 75 be okay? How much power does
it need to handle?

You do not have to shunt solar panels, I believe. If they are producing power and are not connected to a load, so what, it does not hurt them. The controller just disconnects them. Bernie-Original Message- From: Kevin Custer <[EMAIL PROTECTED]>Sent: Nov 12, 2005 7:28 AM To:

Cute method. I believe even the digital station can
output some tones, although I've never heard them.
Mathew also asked (originally) what else needed to be
adjusted when moving the frequency. The transmitter is
already wide-band and other than the VCO, it doesn't
have any adjustments at all.
It is 75 Ohm cable, Paticualrly RG-6 Plenum which has approx 1dB of
Tilt per Octave at 100'. Maximum power is +25dBmV.
Intersted in attenuating the lower channels more than the upper ones,
and I will follow it with an amp on each floor after it is compensated.
Some genius company, that is used
Just buy the tilt compensator or an amp that has one
internal. Try Toner cable equipment and Quality RF

with, there are several more.

Yes, you CAN bypass it with a pair of barrel
connectors. You'll get more power out than you will
with the filters in place.
There are two manuals for the digital station; the
error codes and beeps might be in the manual you don't

Ok, still getting the two beeps. Hooked a dummy load to the exciter, and my service monitor to the receiver, and still only get the two beeps. When I hit the xmit switch on the control, it attempts to key the tramsitter for a moment, then drops the carrier and then just beeps.
