[Lowfer] VE7BDQ in EN90xn (twice)

[Michael Sapp]

John: After the first BDQ decode I started cleaning all the center pins on 
my rx filters and feed line connections in the sequences you were not 
transmitting. Seems that the silver oxide
from the BNC connectors builds up quickly here over the course of 3~4 days. 
It may be ionic related as my total rx power from the NW EWE antenna is 
about 220,000uv as I am wedged about 5 miles between KDKA 1020 and WWNL 1080 
50KW stations. So there is chance the second decode may not have happened if 
I had not gone over the BNC connectors in the RX system. The converter 
itself uses all SMA connectors and UT-141 cable so I do not have the oxide 
issue in the converter itself, just be BNC quick connectors to the rx 
feedline, CM chokes, filters, etc.

That reminds me I need to clean the BNC connector on the FT-817 IF radio,,,,

-25 SNR on a 3400km path is a decent signal, so I would not refer to your 
VE7BDQ 2200m TX signal as "feeble."  K9FD puts -25 signals into EN90xn as 
about average signal level on 630m and half of that path is salt water while 
estimating 1W EIRP for his transmit power. Whatever you have up and working, 
it is doing very well.
