New Firmware (k3fw5r57) Causes Odd Sound

I updated from the r35 to r57 firmware and received reports of an almost imperceptible but noticeable zizzy sound when I quit talking and before the vox drops out on 80M sideband. The listeners say it sounds like a fan in the background, but I have no fans or noise in the room.
I reloaded the r35 and the issue was gone.
Anybody have any ideas? Elecraft?

Right forgot to say...this is on the 4K serial numbered K3 with all options included.

Re: New Firmware (k3fw5r57) Causes Odd Sound

I have no idea how to cure a "zizzy," but I was told I had hum on my SSB
signal after 6 years of perfect audio. Re-flowing the solder joints in
the MH3 cured it. Whiskers, maybe.

Re: New Firmware (k3fw5r57) Causes Odd Sound

The issue went away when I reloaded r53 firmware and came back with r57. I emphasize that the effect is very small and would be missed by most listeners except for some very critical listeners. One friend said it sounded like a clatter mechanical noise rather than a fan. Once you are aware of it, you hear it routinely. It's not a deal breaker, just an anomaly that might be explained and eliminated by the firmware guys.

Re: New Firmware (k3fw5r57) Causes Odd Sound

To clarify, the issue is there with r57 and not there with r53. I did restore the configuration of the rig to a previous configuration which was free of the anomaly, just to reload any parameters that might have changed with the install of r57, but that did not help.
So...since it's so small and hard to notice by the casual, I won't worry about it, but thought that it was worth mentioning as an unwanted artifact of r57. And I don't know which portion of the newest firmware is causing it, the MCU, FPF, or DSP1,2.

Re: New Firmware (k3fw5r57) Causes Odd Sound

I set the TX GATE to ON 10 and the complaints have been eliminated...although one fellow is still straining to hear something. I have always had the TX GATE set to OFF 0 and have over the years gotten complaints of almost imperceptible "ghosts on the audio", and then this "tiny rattle". Maybe I always needed to have the TX GATE set to ON. I don't have any noise in the room, fans or anything, kind of wondered about magnetic noise in the Shure 57 mic from all these monitors, wifi, etc. around here that you can't hear with human ears.

Re: New Firmware (k3fw5r57) Causes Odd Sound

Is it possible you need the KPAIO3MDKT? This cures some issues with electrical fan noise getting into the transmit signal under some conditions after the KSYN3A is installed in all K3 radios and K3S radios before serial (about) 10730.

RE: New Firmware (k3fw5r57) Causes Odd Sound

Could be. I don't have the new synthesizers but the noise is there they say. And just cannot be heard because of the higher phase noise. Maybe my phase noise is low or my fan electrical noise is high.

Thanks for the tip.

Interesting....

That mod is not shown in the Elecraft web pages. I did the KSYN3A updates in my
K3 with the sub RX. How would I know if I need this mod unless someone points
it out to me on the air? My serial number is in the 5K range.

One of the allures of the Elecraft brand is the ability to keep current. That
should not mean just firmware or purchase of major module updates. I'd like to
see a mod list for the subtle hardware changes too. I may not decide to do
them immediately but would most likely do any the next time the rig is removed
from its desktop position.

Same goes for other Elecraft gear like the KAT500 and KPA500. For the XG3 there
was a recent firmware update to it. As of now I see no need for it but knowing
it exists I would do it next time I use the XG3.

Hopefully the powers in charge can consider a more complete mod/update
listing. Maybe a criterion to make the list could be, "What would the factory
do?" By that I mean which are important enough for them to do when a piece of
equipment is returned for repair and updates.
