[AK-VHF] NET: 28 April - 146.52 FM

[Edward R Cole]

Brandon,

Sounds like good use of time.  Yesterday's net 
did not pan out very well.  That's the 
consequence of running a net on the national 
calling freq.  Sometimes it will be in use 
precluding the net.  My signal from the Kenai 
Penin. is not strong enough for small FM stations 
running simple vertical antennas to hear (over local traffic).

I've spent close to $15K for a state of the art 
2m eme station capable of a signal transmitted to 
the Moon and back over 500,000 miles (even when 
running only 150w).  So the shoe goes on other 
stations to improve enough to copy me over a 70 
mile path.  I was asked why I don't run a 
kilowatt on the net.  Actually tried it once 
several years ago and SSB quality was poor.  My 
amp is run closer to class-C or B so not linear 
enough for voice.  Plus high blower noise in the 
shack would effect the mic.  New 1200w sspa in 
the works will replace the 8877 and HVPS.  I 
should be able to run 600w SSB with it.

SWR is >2:1 above 146-MHz on the eme array which 
is not kind to solid state amps.  FM can only run 
at 100w out of the 150w amp.  I may have a new 2x 
array of 11-element yagis for full-band use on 2m 
when my 6m array goes up next month.

Your project sounds very nice.  Take some photos 
(include detail close-up's); would make a nice 
article for AARC Newsletter or on a  website!

Net will be cancelled next Saturday as I have a 
conflict at 9am on Saturday.  Net can go ahead 
without me as NC if folks desire.
