[Elecraft] Downgrading

[Ed Cox KE3D]

I am having a problem with the new release.  When I reduce the filter 
width to jump from the wide fillter to the next narrower filter in CW 
mode, the DSP dies or hangs. I get E 00000C  ERR DSE on the front 
display and the RX goes dead.

I also get a very loud squeal when turning ON the rig.  The squeal is 
not effected by the AF volume.  It is 1.5 -2 KHz and quite ear 
shattering lasting 2-3 seconds.  Is there a straight forward way to 
revert to an older firmware like 1.78/1.58?

Regards Ed KE3D

I thought I had the new release working earlier but after dinner the 
new symptoms showed up.
