hi Wayne, Your new firmware is vy much appreciated and I am very happy with many features though not everything tested yet. The update went without a problem, congrats - this is very well done.
I have a peculiar behaviour with SSB modulation that I have to report: wayne burdick schrieb am 3 May 2008 um 17:29: > * SSB TX POWER CONTROL improved.

(using a Heil Proset with HC 5 Element) RF display is about 40 % max. But! when I key the transceiver with the CW paddle in SSB (new feature, very welcome!) I suddenly get full output also with normal speech. If I twist the power a little up or down, I am back on 40 % output, with one Dit in CW I can have the full power back. I am curious, if I am the only one with this problem. btw, modulation reports on the air are excellent. Loud and clear, vy good readability. 73! de Werner OE9FWV -- If god can be god, why couldn't I?
