Fortunately the European QRM seemed to cause me more problems than the others and eventually subsided.
We had a very lively and interesting discussion on several topics, these included: The K3 on AM with the later firmware (sounds OK and is tightly controlled on bandwidth at +/- 3KHz). K3 TX IMD figures, 120 Watts vs 100 Watts and the significant improvement when the power is reduced to 25 Watts. Determining the mod state of an early serial number K3 which came from an SK estate. Source of PowerSonic 1229 batteries for the K2, we couldn't find any in the UK. 5 MHz UK allocation and re-tuning the early K3s, also potential spurious problem on early serial K3s on 5 MHz - prior to the "MK 2" driver and PA release around January 2008. Why some microphones sound rough? We had two stations who started the net with very poor audio but both fixed their microphone issues quickly. We also discussed our top three firmware issues for attention by Elecraft, these were: 1. SSB ALC not controlling the peak output well enough when running reduced power to drive a linear. 2. Not being able to adjust many of the controls on the K3 while transmitting. 3. A means of turning the EQ on/off without zeroing the settings, per mode would be a bonus as would an "A" or "B" setting (applied to TX and RX equaliser). We also thought it would be helpful if a roadmap of firmware development was released, so at least the user community would have an idea when a particular feature would be looked at, or implemented... I will post these separately to Wayne, Lyle and Eric for consideration. Stations this week were: G4DQP, Vince G0MJW, Mike G0VGS, Ian GM0ELP, Doug M0CIC, Roy GM3SEK, Ian M1PAF, Paul G4JTR, Vin 73 until next week Dave, G4AON K3/100 #80, Acom 1000, dipole ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
