[Elecraft] Receiver slow to recover ?

[Merv Schweigert]

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?
