Control Codes:
10* turns off PL
11* turns on PL

07/18/09 With the network analyzer we checked the cables and duplexers. We found the receive side from the repeater to the antenna connector had 2.0db of loss. The transmit side had 3.6db of loss. That means half the out power is lost from the transmitter.

10/16/08 a work party went up greylock and upgraded supplies. 222.1 received a new duracom switching power supply.
08/23/08 All seems well. AC Power usage = 69watts at idle, 270watts on transmit.

9/28/06 STATUS:
38watts forward 1 reverse
PL 100hz
Scom 7k controller
GE Mastr II repeater
Circulator
9/28/06 n1fgy, kj1k, wa1zhm, k1ttt (maybe others) pulled new hardline up the tower to re-activate 224.1!
5/11/06 Repeater is up on a 6foot antenna in the attic of the lodge.

4/26/06 Antenna has 6 to 1 SWR! This is BAD!

5/5/06 Details of new circulator for 224.1 received from wa1zms.
it is tuned up dead on 224.1.
fwd insertion loss = .49db
fwd return loss -27.69db
Very nice curves
Reverse:
Again dead on 224.1mhz
Isolation (reverse) insertion loss = -22.1db
Reverse return loss into dump load = -24.65db
Very Very nice and clean. Perfect.

4/1/06 Controller needs to be cleaned up and programmed.
