I'd like to be able to transmit in Data-A mode through my 6 Khz AM filter. Being able to see ~6 Khz of spectrum in the waterfall window would be great.

That's more than enough for any reasonable amateur data mode and will keep users from shooting themselves in the foot. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of zibs > Sent: Friday, September 19, 2008 10:28 AM > To: [email protected] > Subject: Re: [Elecraft] K3 PSK31 with Digipan > > > > But in Data A mode, one can expand the receive width out to 4 kHz > using the 2.7 kHz filter.
