Data Modes for all Occasions

I recently completed a talk at LEFARS on data modes for all occasions, the aim of the talk was to explore alternative data modes. We have all received the very popular PSK, most likely on 14.070 but many other data modes exist some offering much greater reliability and alternative uses.

The slides will hopefully get you thinking about other data modes and some of their advantages and disadvantages, how to identify them  and what programs to try.

One such free program HRD can be found online, although if you want support for modern radios and bug fixes why not use the try before you buy option on the paid HRD website.

You can download a free copy of the program, and read more online at ON4NB website.

A handy guide to installation can be read here.

Ive been using it for a few days now, but its too early to test its robustness. Many digital modes come and go over the years, but its always interested to test and understand the advantages and disadvantages.  It certainly looks very much like PSK31, but the program helps identify that by a CW ident SIM and in PSK31 you will decode NEW SIM31 on your screen.

It also has an interesting “beacon mode” that can fully automate QSO. Imagine the joy of leaving that on overnight, and in the morning finding out you have worked 10 new DXCC while you have been tucked up in tog heaven dreaming of that 30 meter tower and 5E stepper IR …
