[Elecraft] K3 in WPX SSB with 2.7 roofer

[riese-k3djc at juno.com]

actually loading coils were to reduce overall  loss
by helping to cancel the line capacity
before amplifiers 1000 cycles was the frequency passed with 
best loss Characteristics,,,, the phones were designed to emphasise that
frequency
"whats that you say "
making phone calls werent for sissies
