Bill, testing on PSK31 TX, using USB and ESSB set to 4 KHz, centre freq at 1500 Hz (normal K3 DSP setting)... I can obtain full power from 300 Hz to 3500 Hz on the waterfall, the power drops off abruptly above 3500 Hz. By moving the centre frequency to 2000 Hz I can transmit up to 3700 Hz.
On Data A, the upper limit is 2900 Hz, I don't think ESSB works on Data A. Although the menu suggests it is turned on, there is no "+" on the LCD display. The advantage of using Data A (as opposed to SSB) is that you automatically select the appropriate mic or line input, per mode. Maybe wider data modes could be incorporated in a firmware update. 73 Dave, G4AON ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
