Re: [Elecraft] K3 Beta Firmware Rev. 3.66: AF output protection
Both 3.66 and 3.67 appear to be available as Beta downloads. I haven't yet installed 3.66. Should I skip it and move on to 3.67? 73 to all Geoff G3UCK - Original Message - From: Wayne Burdick n...@elecraft.com Subject: [Elecraft] K3 Beta Firmware Rev. 3.66: AF output protection K3 beta-test firmware revision 3.66 (with DSP rev. 2.48) is now available. __ 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

Take the latest one out there. Wayne advances the version for cause. 73, Guy.

[Elecraft] K3 Beta Firmware Rev. 3.66: AF output protection
K3 beta-test firmware revision 3.66 (with DSP rev. 2.48) is now available. AF Output Protection: The DSP now senses when AF output would be so strong as to drive the speaker or headphone amplifier into the clipping range. If this happens, AF is muted until you reduce signal levels, protecting your ears (and transducers). Normally, this will only happen if you turn off AGC while an extremely strong signal is present. If you hear the receiver mute under these circumstances, simply reduce gain by some means (back down RF GAIN, turn off the preamp, turn on the attenuator, or turn AGC ON). Another possible source of excessive audio is a DSP numeric overrange. DSP code has been changed to eliminate such cases, and we've had over 100 K3 users field-testing this new code with no reported AF anomalies. But the new AF output protection is always in effect, so it acts as a backup. Please send any questions to k3supp...@elecraft.com.

Re: [Elecraft] K3 Beta Firmware Rev. 3.66: AF output protection
That's a great feature; can't wait to try this out at home. I've been deafened more than once by accidentally turning off the AGC! Thanks Wayne and crew.

Re: [Elecraft] K3 Beta Firmware Rev. 3.66: AF output protection
WorksSounds like an old time telegraph sounder clicking away. Is there any means to disable it in the menu? Before, with AGC off, a static pulse would hit and just produce a distorted click but I could still copy cw. Now it completely blanks out everything. I'm not too sure I like this feature.

Re: [Elecraft] K3 Beta Firmware Rev. 3.66: AF output protection
That's why it's a beta release :) We're seeking additional input on this revision and will make an adjustment to the behavior ASAP. tnx Wayne On Dec 8, 2009, at 1:51 PM, Steve Ellington wrote: WorksSounds like an old time telegraph sounder clicking away.
