I'll take a look at it.

Not really always. As you know I will use the hamlib to control the 
transceiver from my own psk31 program. Usually you will have the transceiver 
in the wide/normal mode to see nearly all signals in the up to 4kHz wide 
waterfall. But if you have qrm you will switch to an smaller filter (and the 
frequency of the tronsceiver should be changed so that the wanted signal is 
in the biddle of the bandwidth, but thats is not a problem of the hamlib hihi)

Hmm... I only know the FT-920 and he has different opcodes for band and 
bandwidth. But why not thos way?

Here I also only know the FT-920.. he has the modes DATA-USB and DATA-LSB. 
What about naming the modes this way? AFSK/FSK switching is done here a small 
switch on the rear panel
