[Elecraft] Receiver slow to recover ?

I had this symptom (and it drove me nuts) with my IC-7800 when I had a 40
meter antenna linear loading wire that needed to be cleaned up (loosen a
saddle clamp, move the saddle clamp back and forth a bit, tighten the saddle
clamp).  

I'd also expect this with sticky relays in the amp and/or antenna switch
box. I suppose any sticky relay anywhere in the T/R path could cause this
symptom.

This isn't to say it couldn't be the firmware version, but this is the sort
of symptom that could have a lot of causes.

Using 3.44 beta,  since installing I seem to have a problem
when going from transmit back to receive.  Not all the time
but often enough to notice. 
It first seemed as if the vacuum relay in the Alpha was going
bad, like bad contacts,  the receive after transmit would be
way down.  If I hit the key it came right back.   The relay
is fine, and further checking it seems as if the receiver is not
recovering fully at times.  Always cured by keying the radio
again and it pops back to normal. 
Not using NR or NB just normal settings on CW. 
Any others notice something like this?
