Re: Transmit Function Drop Out

[Elecraft mailing list]

I am sending this to you and to the Post

 

Issue - Speech would drop out randomly during a transmission utilizing the foot switch or the voice keyer and could be heard thru the monitor.

I checked out the complete station prior to taking it to the Caymans and found no issues making numerous QSO’s.

Voice randomly dropped out  from the day I got there thru Saturday at the start of the NAQP contest.  Setup was a K3 with the latest download, portable computer, power supply and the station antennas. HRD version 6.3.0.555 logging software was being used.

During the week I checked all the connections, open up the radio and checked all of the cabling, confirmed that SWR was good (tried 3 antennas)and checked that I was not losing power (tried 2 PS). Right before the contest I changed the foot switch and went to N3FJP Contest software. Not one issue occurred during the contest. The next morning I switched back to HRD software staying with the second foot switch and the problem came back. No cabling was touched overnight.

At the suggestion of Elecraft, I bench tested the same package at home and the problem was back. I changed to a different computer with a load of HRD 6.2.9.355 and the problem was gone. I swapped back and forth and it went with the 6.3.0.555 software set. I uploaded a fresh/new version 6.3.0.613 and the problem went away. I ran voice loops with memory keyer for 10 minutes 2x without issues.

Taking it to Hawaii for WPX SSB.

K3 100 watt worked fine at home last week and was transported to the Caribbean.

Started Immediately this morning, some time into a transmission on SSB, keyed with a foot switch or the voice keyer, the transmission just stops. This does not always occur. If I rehit the foot switch, transmission starts up again.  I have not updated the software in 6 months and the 3 different antennas are delivering good SWR. +12 Power does not appear to be going away as the receive function is working and I can immediately continue the transmission.
