Re: [Elecraft] K3 Momentary no transmit
G'morning, Frank: I just tried to duplicate what you are experiencing and was unsuccessful. No interruptions.

Re: [Elecraft] K3 Momentary no transmit
Ken, This is firmware problem acknowledged by Elecraft, and previously discussed in this forum If you don't do digital comms, one of the easiest ways to see this is to put the rig in TEST mode and turn on the 2-tone test. Monitor the "transmit" signal with headphones and you will hear it drop out every 15 seconds. The dropout is just for a few milliseconds and sounds similar to a WWV "tick". There may be some variability in rigs, though I doubt it. When I was trouble shooting the problem with Elecraft support, they were unable to duplicate the problem with the rig they initially had on the bench. _ 73, Jim - N4ST -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ken K3IU Sent: Monday, November 23, 2015 03:44 To: n...@comcast.net; elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Momentary no transmit G'morning, Frank: I just tried to duplicate what you are experiencing and was unsuccessful.

Re: [Elecraft] K3 Momentary no transmit
Hi Jim: Now that you mention it, I do recall something about this in the recent past on the reflector. I did my previous test in CW mode putting RF into a dummy load and heard no momentary drop out. I just tried the setup that you suggested below in LSB and I must have one of the rigs that don't produce it because I am not hearing any interruption at any interval. Thanks for the info... 73, Ken K3IU On 11/23/2015 9:34 AM, Jim - N4ST wrote: Ken, This is firmware problem acknowledged by Elecraft, and previously discussed in this forum If you don't do digital comms, one of the easiest ways to see this is to put the rig in TEST mode and turn on the 2-tone test.

Re: [Elecraft] K3 Momentary no transmit
Known software/firmware issue that appears on 12M, 10M and 6M only. Elecraft is aware of it. I wish it was fixed as it drives my amp crazy while working any mode that has 100% duty cycle such as DATA or AM. It is a PITA, and I wish it was resolved. 73 Bob, K4TAX On 11/22/2015 7:54 PM, n...@comcast.net wrote: I discovered a problem with my K3, s/n 83xx.

Re: [Elecraft] K3 Momentary no transmit
This drove me nuts when I first got my K3S. After a few days of testing and reconfigurations, it turned out to be a firmware problem that has existed for years. You will never notice it in SSB modes and the dropout occurs in the spaces for CW. A definite annoyance for those of us using digital modes with transmit times longer than 15 seconds. _ 73, Jim - N4ST -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of n...@comcast.net Sent: Sunday, November 22, 2015 20:54 To: elecraft@mailman.qth.net Subject: [Elecraft] K3 Momentary no transmit I discovered a problem with my K3, s/n 83xx.

Re: [Elecraft] K3 Momentary no transmit
Likewise, when running my amp, when the K3/K3S output drops, the amp gives out a big grunt and this happens every 15 seconds. Rather annoying to say the least and it made me wonder, until it was disclosed as to why, what was going wrong with the amp. 73 Bob, K4TAX On 11/22/2015 9:37 PM, Jim - N4ST wrote: This drove me nuts when I first got my K3S.
