[Lowfer] WH2XND 136 kHz wspr-2

[Michael Sapp]

Garry & All: Did the sealing current thing and cleaned the center pins on 
the BNC connectors to my LPF, the RF isolation transformer, the in-shack CM 
chokes, and the antenna input connector to my FT-817.  I do this every week 
or other week, amazing how the oxide builds up even though the humidity is 
40 % or so in the radio area.  I use these hobby store microbrushes and 
deoxit or alcohol for BNC center pin cleaning....

Looks like a managed to lower the noise and increase the signal level for a 
dB or so, finished the center pin cleaning between TX sequences for the 1952 
UTC capture...

  Antenna connections were cleaned and oiled a week or so back when the wx 
was favorable for outdoor maintenance....

 ( Yes, I know I should have all gold or palladium connectors to prevent 
this kind of oxidation issue )
