[AK-VHF] 927.5 & 1296.100 Status

[Edward R Cole]

All was going good and had both 1296 & 927.50 working fine, but when 
I raised the array my 2m SWR went bad.  Tests with dummy load at end 
of 1-5/8 line good and SWR transmitting up the LMR-600 line to the 
array by connecting a HT is good.  Problem looks to be in that 
connection, but what?

Well I accidently pulled the LMR-600 male N-connector apart so now I 
have nothing that works.

Too windy tonight to try soldering outside at the tower base, but I 
will try to repair the connector in the morning before the 
Net.  Otherwise, I will run the net with my 10-dB vertical using the 
FT-736R and 150w amp on 144.200.
