[Elecraft] K3s+KPA500 SSB Audio Distortion
Michael I also have the same problem. Worked on it with Elecraft Support several times to no avail. I have tried several different microphones, antennas, baluns. Still no joy. I also use 18 watts drive, I had not thought of anything other than rf feedback. I will play with different drive levels.In frustration I have quit using the KPA-500. I hope you are on to something.

Making adjustments to mic gain, compression levels, TX EQ seems to make no difference to this report. These adjustments do change the sound of the audio but do not reduce the reports of muffled or nasal characteristics. I normally run the KPA500 at 500 watts PEP output and the K3s is set to 18 watts to achieve this output. This morning I suspected that this nasal sound might be related to running the K3s at 18 watts as that uses both the 100 watt amplifier and the 12 watt amplifier but in series at very low drive levels. As a test I cut off the KPA500 and ran the K3s at 100 watts and the distortion was gone. As a second test I dropped the drive to 11.9 watts which dropped off the 100 watt amplifier module and runs the low power module at almost full power and the audio was still clean with the KPA500 delivering about 300 watts PEP. Is this something that anyone else has observed? Are there any built in tests or adjustments that might help this issue? I have run the transmitter gain calibration at all three power levels with satisfactory results. Oh yes,?. The condition is the same using a dynamic mic (EV RE50), an Electret Mic (MH4 & CM500) or mic audio from a USB connected computer (Blue Yeti).

Re: [Elecraft] K3 speaker amp chip bites the dust again - CORRECTION!
Wow Dave you spooked me. I just completed the protection install before leaving Yuma for Astoria. I am glad to hear the install was not in vain. hi hi Bill J K7BRR Yuma Message: 13 Date: Tue, 1 Jul 2014 17:53:59 -0700 From: Dave Hachadorian k6ll.d...@gmail.com To: Reflector Elecraft elecraft@mailman.qth.net Subject: [Elecraft] K3 speaker amp chip bites the dust again - CORRECTION! Message-ID: 058BEFA1FA9E42939B8ED88C253D8CDA@Toshiba Content-Type: text/plain; format=flowed; charset=iso-8859-1; reply-type=response My posting this morning about blowing the speaker amp chip was in error. Further investigation reveals that I actually blew out the K3's internal speaker. Ohmmeter measurement at the speaker terminals shows that the coil is wide open. This is really good news, because the speaker is easily replaceable in the field. It's also good news because it points out the efficacy of the E85056 protection mod. My apologies for making a wrong assumption. The symptoms were exactly the same as the two previous failures of the speaker amp.

[Elecraft] KX3 Affordable Heatsink
Johnny I too am using one of John's KB8UHN heatsinks. My first impression is the quality and price. I opted for the unpainted version and I like the way it matches the KX3 lettering and contrasts the black. I have not used it in heavy digital transmitting but this weekend. It fits well with my Sidex add on and cover and my KX-3 still fits nicely in my Crown Royal bag sleeve. hi hi Bill J K7BRR __ 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 Message delivered to arch...@mail-archive.com
