Re: [Elecraft] New Firmware (k3fw5r57) Causes Odd Sound

[ke9uw]

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.

Re: [Elecraft] New Firmware (k3fw5r57) Causes Odd Sound

[ke9uw]

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: [Elecraft] New Firmware (k3fw5r57) Causes Odd Sound

[ke9uw]

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: [Elecraft] New Firmware (k3fw5r57) Causes Odd Sound

[ke9uw]

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.

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.

[Elecraft] New Firmware (k3fw5r57) Causes Odd Sound

[ke9uw]

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?
