Hi all:

Is 4r22 firmware the "latest" software or is there another newer revision?  

I installed 4r22 today and I find that the auto notch *still* has that
annoying momentary dropout in the audio at T/R turnover that I discovered
during SS.  The TX Gate function has the nice ramping decay in this rev, and
the SSB TX audio sounds fine. I recall that the previous release of this
firmware had TX audio issues.

Is there a later rev of this firmware?  Looking at the "beta" folder on the
FTP site, I see that folder is empty.

Also, how do I "backrev" the firmware now?  I attempted to backrev to 4r14,
my last solid firmware release with a working auto notch.  I used to be able
to look at my local folders where I unzip the firmware and choose to install
it instead of the existing loaded code, but this is the first time that I
cannot use that option.  I have been able to do this before, but now I
cannot.

What has changed?

I guess I will have to put up with the "holy auto notch" a little while
longer while enjoying the gate  :)

Thanks in advance
