I'm glad it wasn't me .... or any of the programs that I use. Apparently the default I or II setups do not tie the filter with the mode .... or it's just not using the default setup that you have saved in the K3 when you use external control.

Doing some investigation with the command tester in the Firmware Utility, I think there is a bug in the K3 firmware. It is not changing the filter bandwidth if a band change is made by CAT command and this results in a mode change because the mode last used on the new band is different from the mode you were previously using. If you are on 14.025 CW, and you change frequency to 28280 by sending the command FA00028280000; the K3 changes to that 10m frequency. The mode used on 10m is the mode that was used the last time you were on 10m, but the filter bandwidth remains the same as it was on 14MHz. So if you were last on 10m using SSB, you will end up in SSB with a CW filter bandwidth. If you were last on CW, you will be in CW mode on 10m. This explains why you observe that the filter sometimes changes, and sometimes doesn't. If you were last on 10m in CW, if the software sends a mode change command after the frequency change command, the K3 will go to 10m CW and then change to SSB which will cause the filter bandwidth to change correctly. If the K3 was last in SSB on 10m, then it will change to 10m SSB and the narrow bandwidth become wrongly set as the new SSB filter bandwidth. The subsequent mode change command won't do anything. ----- Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com Zerobeat Ham Forums: www.zerobeat.net/smf -- View this message in context: http://www.nabble.com/Re%3A--K3-More-on-changing-band-mode-and-filters-don%27t-tp17576785p17579881.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
