[FPARC] 2 Meter repeater W4AKH Preventative Maintenance

[Greg Bunting]

All;
On Saturday, Kevin, Ernie, Paul, and Greg did a PM on the 147.345
Repeater (after a yummy B'fast).
Two defects were found; the receiver was 1.5KC low in freq and there
was a bad duplexer to receiver cable.  Both were corrected (=*).
Pertinent data using a Motorola R2210A monitor and Telwave power
meter;
Receiver Freq = 147.9450 *
Receiver direct sensitivity = 0.16uV  (very HOT!, spec is 0.35uV)
Sensitivity thru duplexer   = 0.26uV  (very HOT) *
Desensitization                       0.0dB  (perfect)
Repeat audio 3.2kHz in, 3.8kHz out
Transmit freq = 147.3450
Transmitter power into duplexe= 80W Fwd, 3.0W Refl
Transmit duplexer to antenna   58W Fwd, 1.5W Refl

The 444.800 was not done due to time and the fact that it was just
built last spring.  Kevin and I did the PA and duplexer last month.

See most of you Wed Eve.
