I installed the 4.81 beta firmware and I am able to change the crystal filter offset as described in the firmware notes. I can hear slight differences in a CW signal between 0.1, 0.2, and 0.3 KHz. What I don't understand is what does it mean. Previous to this release I would have assumed that the crystal filter is centered on my chosen CW pitch suggesting a 0 KHz offset. If I choose one of the 3 offsets am I now listening (and transmitting) slightly off zero beat. Why would I want this? Wouldn't I also want a 4th choice of 0 KHz?
Explanations in layman's terms would be appreciated. 73, Mike K2MK -- View this message in context: http://elecraft.365791.n2.nabble.com/Crystal-Filter-Offset-in-4-81-What-does-it-mean-tp7583674.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
