[AK-VHF] AK-VHF Net 9am Sat

[Edward R. Cole]

The Alaska VHF-Up Net will meet tomorrow at 9am (AKDST) on 146.52 FM 
simplex.  The Net meets on FM once per month to let those with 
interest in weak-signal VHF and above access if they don't own SSB/CW 
equipment.

My four-yagi eme array (19 dBd) is lowered for maintenance so I will 
not have as strong a signal as normally I do.  However, I did some 
trouble-shooting today and discovered that the high SWR on my 
high-gain omni collinear whip was with a coax section which I have 
replaced.  The 17-foot high collinear, base mounted 20-feet above 
ground, has 9-dBd gain on 2m and I have a 1-dB NF preamp at the radio 
which helps reception quite a bit (about 3-4 s-units over the radio by itself).

I will start out with 50w and see how well I am heard.  I can add the 
amplifier but it only boosts power to about 75w so not a big change 
in power.  I have to use my antenna tuner with the amp on 146.52 to 
get good input SWR into the amp (because one transistor has failed 
and that has the match messed up).

I also checked the antenna on UHF and it shows almost perfect match 
432-450 MHz.  12 dBd gain on UHF (that is as much as my 11-element 
UHF yagi which isn't connecting thru the TR relay - dc voltage issue, I think).
