This is probably off-topic, so any replies should go to me directly.

I'm coming here because so many of you are involved with various forms of digital modes. Digital is not my thing. For one: too many toys, too little money and/or time, too involved into starting up in POTA.

However, I'm studying for the Extra ticket and, of course, there are a number of potential questions about digital communications. Some of the questions mention modes and methods of modulation that are completely unknown to me and - more important - in none of the on-line sources I found during a 2 AM search. Most of them claimed to be the complete guide to digital, yet modes on the test were not mentioned and beyond the obvious ones, there didn't seem to be a consistent list of common modes.

I don't want to be a digital expert, but I would like to find a reasonable comprehensive primer on digital that goes beyond the surface. I feel I should be able to do and know better than just memorize the answers for the exam pool.

Hi Bob,

I won't do a long reply on the forum. I found several resources, including some paid.
I was looking for a little more meat for each mode rather than - mostly - superficial
descriptions and comparisons.

From the ARRL web site:
"JS8call has replaced PSK31 as the keyboard to keyboard mode, though 20M PSK31
can still be found."

I've gone through 17/58 chapters of the resource I'm using. So far, nary a word about JS8call
but PSK31 appears among and is the answer for no small number of questions from
the Extra pool.

Go figure.

Let's go off-line from here. I don't want Scott jumping on my old bones <g>

Clear Skies,
