Not being  a high speed CW op nor a contest CW op, I find that QSK is, well, just very nice.   I don't need to hear between the CW elements, nor even the letters, but more so in between the words.   Some ops have  a clean fist but run all the words together.  No spaces.  Drives me nuts.

Re: [Elecraft] K3 QSK Timing

I have always felt as K9ZTV does. I don't mean to speak heresy here, and I would never deny anybody's right to use full QSK, such as when chasing DX. However, I have never felt the need to hear between dits. Between characters or words seems more than enough for me, especially at the CW speeds

Check the obvious. Are you sure you didn't accidentally turn down the RF and/or AF gain on the SubRx? I know how easy it is to do. I have seen me do it. Buck, k4ia Honor Roll 8BDXCC EasyWayHamBooks.com On 6/10/2020 2:26 PM, hawley, charles j jr wrote: Maybe you could remove the sub and

Re: [Elecraft] [K3] Sub receiver intermittant failures

Do NOT send in just the sub! (also an intermittent will invariably NOT fail when here at Elecraft). Like Jack said, check the sub KSYN3 by tapping DISP and look for PL2 voltages or SYN2 OK (tech mode must be on). When wiggling all the cables, don't forget the one at the back of the sub. Look

Jim, you are right, too often we mean counterpoise and say ground. Hopefully Peter can start doing his experiments based on our wisdom and I'm curios what will work ok for him. 73 Gernot DF5RF Am 09.06.2020 um 22:42 schrieb Jim Brown: On 6/9/2020 1:21 PM, g...@gmx.net wrote: anywhere then you

That probably wouldn’t help. In this case the system includes the SubRx, the Synthesizer and all the interconnects and cables that connect these to the rest of the radio. I would check the interconnects, especially the tmp coax cables that go from the SubRx to the rear panel connector and to

Re: [Elecraft] K3(s) main oscillator calibration

I agree 100%. However, the implication for using it for the reference oscillator calibration was / could be perceived as not a good way. John N8UR did an interesting study on the effects. https://www.febo.com/pages/hf_stability/ 73 Ben W4SC Sent from Mail for Windows 10

Re: [Elecraft] K3 on motorboat.

Speaking somewhat broadly, Science is basically a quest for understanding of the physical world we live in.  Engineering is the science of intelligent tradeoffs in a quest to create "stuff" using the science and technology.  Many of the tradeoffs are technical.  Others are economic, ergonomic,
