UPDATE CW Keying Issue

Paul Matthews #4718 I have been fighting with the X6100 for some time now trying to figure out why the rig will miss the last dah on occasion.; for example the number 4 or a letter V omits the last character. At times this is fluid other times it may happen as many as three times in a row and then it works a few times and then may only do it one time. VERY frustrating. Well, this morning I was using my old Kenwood TS450s with my MFJ keyer paddle so I decided to try it on the X6100. I set the keyer mode in the rig to manual and I let the MFJ do the work. That solved the problem. Now CW is fluid! I guess I have one of the few rigs with this problem because I have not seen other complaints about this problem. This proves there is a glitch in the internal keyer. I have upgraded to the latest X6100 firmware and R1CBU firmware and it does not solve the problem. I am now very happy with the rig! 73 Paul KE4SC

You need to compare exactly in different versions of BB firmware.
Paul Matthews #4723 Hi Oleg, First, thank you very much for your firmware; I like it much better than the Xiegu program! Since it is working, I am going to leave it alone (at least for a while!). Again, thank you! 73 Paul KE4SC
scot forshaw All Messages By This Member #4724 开云体育 There is no glitch in my opinion, but adding a small clip on ferrite to the paddle cable at the radio end did solve all my iambic paddle jet error woes. Before the ferrite I had miss keys and errors but after adding they were gone. Many many good qso on CW with the 6100 perfectly. The ferrite is common to solve many issues .? Thanks?

Paul Matthews #4725 Hi Scott My question: if it is a ferrite issue on the cable why is there no issue with a different set of paddles and an "un-ferrited" cable? In manual mode there is no issue with the keying. I think, in my case, there is a glitch in the keyer. 73 Paul
Rainer DG1SMD All Messages By This Member #4726 Paul, EMC issues are seldom straightforward. Even if you did not plan it that way, every wire/cable you connect to your radio becomes part of the antenna system, especially when operating in the near field of the antenna (think portable) and without a good earth system (think endfed). One of your keys might have rf suppression capacitors built in and a shielded cable, the other not. Even differences in cable length might play a role. Then it depends which type of ferrite you use: you need one that has a high impedance at HF frequencies, not at VHF and up like most stuff you can recycle from consumer electronics or buy at ham flea markets. Every time i have to solve an EMC problem at work, i have to carefully select the correct ferrite type for that problem. This is the cause why sample kits are so popular in EMC work :-) Direct conversion receivers add another layer of problems to this: W7ZOI, Wes Hayward lists everything in that regard in his book "Experimental Methods in RF Design" (also called EMRFD for short). Chapter 8 contains all you want to know about direct conversion receivers, even things you dont want to know. Wes popularized DC receivers with his Nov. 1968 article in QST and has decades of experience with them. So in short, when solving an EMC issue, dont stop when the first approach doesnt seem to help. EMC work is like peeling onions - the suffering does not stop with the first layer... 73, Rainer DG1SMD
scot forshaw All Messages By This Member #4727 开云体育 Could not have put it better myself.? In short add a ferrite clip in (even Yaesu clip on a ferrite to their ?130 USB microphone) and see if it works. I use only a small one with my TinyPaddle on a 3.5mm extension cord and it killed all my keying errors.? But the flip side is if the lawyer has glitches why does it not manifest on other paddles etc.? I’d try the ferrite and see . toggle quoted message Show quoted text On 21 Jan 2024, at 09:15, dg1smd@... wrote: ?Paul, EMC issues are seldom straightforward.

Michael VE3WMB Member Profile All Messages By This Member #4729 Rainer, DG1SMD is absolutely right.? EMC issues can be totally unpredictable and often just don't seem to make any sense.? The best approach with the X6100, IMHO, is to put ferrites on every lead going into the radio. This doesn't guarantee you won't have issues but it will certainly reduce the chance. I would also be very cautious in using the X6100 with an EFHW antenna for the same reasons. If you are going to do so then I would recommend using an elevated 0.05 wavelength counterpoise attached to the antenna ground and a good common-mode choke on the feedline at the antenna. I mentioned previously that I had some issues with "wonky" SWR readings on the X6100 when using it with my Alex Loop. I fixed that problem with a few ferrites on the antenna feedline but I had never seen any issues of this kind with this antenna on any other portable rig that I own (and I own more that a few).? So the moral of the story is don't underestimate how sensitive the X6100 is to RFI.?? Cheers Michael VE3WMB
Paul Matthews #4730 Thank you to all on the information you provided. I have never had many RFI issues so I never thought that could be it because the problem was so erratic. I found some MFJ "RF Suppressors" (MFJ 700 A4) that I am going to try on all the paddles in the shack that I use. I am also going to coil up the cable to minimize the length along with the "suppressors". I think it will be interesting to see if there is any difference or if it will minimize the occurrences. Thank you again for the help! 73 Paul
