[CW] Radio without antennas

[Danny Douglas]

Every third operator you work will tell you that you have audio on your 
keying, if you used that on the air.  There are several software packages 
out there that will do it.  MixW does, and I used it for a bit, until I got 
an MFJ 1278  which also allowed direct keying  and now have a Rigblaster 
Plus that does a good job of keying the key line. Just using any cw 
oscillator, into the audio jack will do it too.
