As in the previous tests, the signal could be heard also between the
key-down phases.
Hi Wolf,
Last summer I posted the following message...

Actually the Emission Designator for SAQ transmission was 52H0K1A an
unusual mode, but for us the term A1A or CW is synonymous to the Morse
code over the ether (our wireless world).

And this is the feedback from somebody that probably didn't heard the
SAQ transmission...
The first A in A1A designates an emission with an Amplitude Modulated
carrier, where the modulation type is "double sideband". The 1 in A1A
means there is single channle with no subcarrier (so the frequency
deviation of the "double sidebands" is zero). The last A describes
the reception as being "by ear".
The K in 52H0K1A designates an emission of a pulse type where the
pulse is amplitude modulated. The 1A in K1A is the same as in the A1A
case.
It seems that K1A describes CWK transmission just as well as A1A does.
