Topband: PSK-31

[Jim Brown]

In the recent discussion of allocations and band segmentation, someone
seemed to be suggesting that PSK31 was a broadband mode. When I look at
signals on my PSK31 software, they seem rather narrow band -- typically
under 100 Hz -- unless the transmitter audio stage is being overdriven
to produce IMD and HD, in which case the signals can easily get 1 kHz
wide. Am I missing something?
