New 2.58 firmware - changed audio settings.

NZ0T
I downloaded the new 2.58 beta with no problems but the regular group I ragchew with on 160 SSB immediatly noticed that I was overdriving the rig.  I had not changed the mic gain or comp settings at all from what this group had helped me set it at when I got the rig a couple of months ago. We found that if I reduces the comp from the 10 I was at to 0 and the mike gain from 20 to 18 everything was fine.  Moving the comp up to 10 gave plenty of presence for DX work but 20 was too high.  I use the MH2 hand mic.

Anyone else noticed this?

Hi,

No, I had not noticed that. I updated last night and worked several 80m DX contacts (80m was in fantastic shape last night), but did not solicit nor receive any audio reports. But I had no problems being heard and copied. I also did not notice any difference in the ALC readings nor did I notice any change in my analog metering of the RF output. I run with a compression setting of 20.

This is not the first time people are reporting mysterious and apparently unintended changes to the audio processing, both on the receive and transmit side. And almost never do we hear any confirmations or denials from Elecraft. Are you sure the changes are for real or could it be that your buddies have developed a reduced tolerance for processed audio over time? Could Elecraft please indicate whether there are any intended changes to the transmit audio processing in version 2.58?

I am sure the changes are real as they noticed it on my first transmission.  Conditions were excellent with strong signals.

It has been a few months since SSB audio processing was touched.  The RF
side has been worked on, however, for improved power control and ALC action.

It may be the improved ALC action then.  Not a  problem for me once adjustments were made.
