I thought the FT-4 signal is only 90 Hz wide

Hi Gerard,
the Region 1 band plan specifies modulation not exceeding 500 Hz for
7046.5, Region 2 specifies modulation not exceeding 500 Hz for 7046.5,
and Region 3 specifies bandwidth not exceeding 2000 Hz for 7046.5. So
anything approaching 3kHz even temporarily seems non-compliant to me.
Of course it's not the full 3 kHz but a couple of hundred Hz less than
that. VARA uses OFDM I believe and varies the mode on each of the carriers
to maximise speed over the full channel.
ARDOP has various BW modes such as 500Hz, 2500 Hz and negotiates the lower
of the two stations.
Cheers,
Gerard

Tnx Jari. I just thought 7047 was suspiciously quiet :)
