[Elecraft] [Elecraft-KX] Peter Martinez And The CW-To-PSK31 Feature

[Wayne Burdick]

Hi Tony,

I, too, am an avid user of the CW-to-PSK31 feature, which is available on the K3 and K4 as well as the KX line. I've even used it during Field Day, which is a hoot, especially with a tiny KX2 and its paddle being all the gear you need (no computer or keyboard required). All of these rigs also do CW-to-RTTY with the keyer paddle. 

Some would argue there's no activity in ham radio, or perhaps life itself, more rewarding than making RTTY contest QSOs using a 1 pound radio with a whip and an attached keyer paddle while operating pedestrian mobile :)

Of course I may be biased, being the nut-case who dreamed this up and wrote the MCU firmware. But I'd also like to give credit where it's due: the DSP code for this was written by Lyle Johnson, KK7P. 

One tip for those using PSK31 as a casual operating mode: you may need to use RIT or XIT to fine-tune the offset and obtain the best copy.

73,
Wayne

Peter developed the mode some 25 years ago so I thought it would be interesting to ask if he ever imagined it being used in such a unique way. To my surprise, he wasn't aware it existed!

I suspect there's a slight advantage in weak-signal performance over CW as well which doesn't hurt when running QRP.
