Re: [Elecraft] Key Clicks? Maybe, Maybe not.
Thought I should post this, Steve I just QSOed and I was 20 over at his QTH (40 watts drive into a TenTec Titan 425) He checked my signal both with full semi break-in and deemed my signal clean. That was the same finding by the folks I interrupted to give me a check-out It does beg the question of why it would be heard by others. The possibility some radios hear clicks because of internal issues with their receivers does seem likely. I am most relieved I have no keying issues... I did not think it was the K3 in any way but perhaps something interfacing with the titan amp. This particular amp was designed by Dick Frey who used to be the principal engineer at Harris corp (Dick has the serial # 1 Titan 425) and I know he designs nothing but the best but anything can break down. Time for some of that special cider I make at this time o' the year... Gary KA1J P.S. Thanks again Steve. Gary KA1J Gary: Wonder what the other guy was using for a rig? The ICOM PRO's tend to make every strong cw signal sound clicky. Give me a call on 160 and I'll be glad to listen on this K3. I'll be on tonight. Name your freq. and time. 73 Steve Ellington N4LQ n...@carolina.rr.com - Original Message - From: Gary Smith g...@doctorgary.net To: Elecraft@mailman.qth.net Sent: Wednesday, February 04, 2009 9:00 PM Subject: [Elecraft] Key Clicks? Maybe, Maybe not. I have an interesting thing to figure out... I have a K3 and my amp is a TenTec Titan 425. I was CQing DX on 160 CW today using semi break-in and a fellow came by and said I was generating key clicks. He came back and asked me to QSY to SSB and I looked for him but didn't find him. I went up in the band a bit to a local net with strong signals and asked if they'd listen to my signal for clicks. I sent CW and the answer came back my signal was fine, no issues. A KP4 said I had no clicks. So I went to the DX cluster to see what was on there was a note from the fellow who asked me to QSY telling me where to meet him posted 20 minutes earlier. Not reaching him I sent him an email and he returned with a nice note saying the following when I said I don't have any key clicks: Hi Gary yes you do but it may be that you don't have enough delay in the amp there are a number of guys on the TB chat the heard it ..it only occurs on the dashes but at least 5 others heard in including a couple very knowledgeable guys that where the delay idea came from. I called Elecraft tech for suggestions and the only thing we came up with was to change the Tx delay from 008 to something higher.. Before I do that, I wonder if there's any other ideas from the group as to what might be an issue. To recap and expand: I was using semi break in and sending around 22WPM using the memory keyer in the K3. As the it was semi-break-in, there was no relay on the amp that was being switched on or off in-between characters or even in-between words. The Titan amp is a QSK amp so it has no issue with fast relay turn- around times. When I transmit there are no apparent issues with feedback getting into the K3, no relay sounds from overload etc. I was transmitting with 45W into the Titan. The fellow said it was on the dashes that there are the clicks. Ideas?

Re: [Elecraft] Key Clicks? Maybe, Maybe not.
I'll go ahead an mention it. The ICOM PRO series is well know for hearing clicks that aren't there. In fact, the rx in those rigs has the ability to convert static into ear splitting clicks. When they first hit the market, some owners were saying The DSP filters are so sharp that when you tune off frequency, you can't hear the carrier but can still hear the clicks, trying to make us believe that the clicks were actually present but just couldn't be heard on lesser receivers! I had both the PRO II and PRO III. Both were bad for this but otherwise great rigs and I still miss the handy scope eventhough I have LP-PAN, which is far superior, I still miss the built in bandscope. So KA1J sounded very clean on this end but maybe not on a PRO.
