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.
But PSK31 is still widely being used today... unlike the TOR modes!
In days of old (yea I'm eligible for the QCWA
I have 11 months to go!
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.
While the US General Class test pool does not have any questions about AMTOR, there are quite a few dealing with PACTOR:
G2E02 How can a PACTOR modem or controller be used to determine if the channel is in use by other PACTOR stations?
G2E03 What symptoms may result from other signals interfering with a PACTOR or WINMOR transmission?
G2E09 How do you join a contact between two stations using the PACTOR protocol?
G8B05 What is the approximate bandwidth of a PACTOR3 signal at maximum data rate?
G8C05 In the PACTOR protocol, what is meant by an NAK response to a transmitted packet?
G8C06 What action results from a failure to exchange information due to excessive transmission attempts when using PACTOR or WINMOR?
And these questions are from the EXTRA test pool:
E2D07 What digital protocol is used by APRS?
E2E09 Which of the following HF digital modes uses variable-length coding for bandwidth efficiency?
Which of the following digital modes is especially useful for EME communications?
B. PACTOR III
AMTOR and PACTOR are not the correct answers to any of these, but they are still used as 'distractors".
