This is a bit OT, but...I took a peek and see that MultiPSK supports AMTOR'S FEC and ARQ modes.. Hmm. When I have time, I might just load this up, and play some.
In days of old (yea I'm eligible for the QCWA ) when establishing an AMTOR contact, you called CQ and transmitted your call using FEC. The receiving station who heard your CQ would program your call into his terminal and would come back and establish a link using ARQ.This is a bit OT, but...
AMTOR FEC (also known as SITOR-B, and used in the NAVTEX protocol) is equally ancient technology, and I doubt there are many users in the ham world anymore. It's used by a number of maritime stations for broadcasts; check the links in this page..
But PSK31 is still widely being used today... unlike the TOR modes!Looks like Industry Canada needs to update its question pool - I seem to recall that when I took my General license test, there was a question or two there on PSK31 that I had to answer.
I have 11 months to go!In days of old (yea I'm eligible for the QCWA )...
While the US General Class test pool does not have any questions about AMTOR, there are quite a few dealing with PACTOR:Out of interest, the Canadian government still has a couple of questions in their question pool for the basic amateur test that deals with AMTOR.
