It's amazing how this went from a defective fuse holder to a $700 amplifier.
Maybe we should meet and discuss our option.

          Due to an obvious signal reduction from the repeater transmitter,
a site visit was necessary.

 

The crew was myself, Len, WB2HKK; Rich KB2LLM; and Pete KD2ARB.

 

We arrived to find the Mirage B108 ( 10 in / 80 out ) amplifier had NO
POWER. The power output to the antenna, measured on the Motorola service
monitor, was a whopping .39 watts! Yep, only 390 milliwatts to the antenna,
yet we all could still hear it!

 

I removed the 15A fuse in the amp ( that did NOT seem blown ), and replaced
it., The amp was then working. After a keydown for about 15 minutes, it
again failed. The fuseholder itself was screaming HOT. I tried another fuse,
with the same results.the fuseholder got VERY hot. Tapping on it made the
amp fail momentarily.

 

The decision was made to put the standby repeater tray on air. The output to
the antenna is now 16watts, only about 3dB down from before.

 

The right thing to do is put a real repeater amp in place. A HENRY amp ( 10w
in / 100w out ) to match the 220 amp will be about $700.00. This will need
to be approved by the officers.

 

PS: We should get a crew up there soon to trim some branches that are over
the FiOS lines.
