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. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Merv Schweigert Sent: Tuesday, October 20, 2009 10:31 AM Cc: [email protected] Subject: [Elecraft] Receiver slow to recover ? 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?
