[TenTec] Radio Science + QSK = Radar

[Martin, AA6E]

QSK is very helpful, because you hear the echo after every dit or dah.
 (It's pretty distracting to hear echoes while sending.)  I never
heard it with my old non-QSK rig with a slow R/T relay.  I don't think
you need a "superstation" to hear the effect, but an antenna with
directivity and low angle takeoff should help.  I use a barefoot Orion
with a 3-el SteppIR looking out over salt water, 40 ft above ground,
60 ft above sea level.
