It's been a long time since I sold my K2s, but I have more recent experience with K3s, and I had a problem with one of those mini-coax jumpers. Elecraft can send some to you. And if it's a female connector that solders to a board, they can send you that. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] dead K2
Oscar, First remove the KAT2 from the K2 entirely, including the cable to the control board. Then connect a dummy load to the BNC on the lower rear panel. Try transmitting (do a TUNE) and see if there is any RF. If there is, you are fortunate, fix the coax ground to the KAT2 and put it back together. If not, you have some troubleshooting to do. Get an RF Probe (or an oscilloscope) and follow the procedure for troubleshooting that is printed near the back of the K2 manual (download if you do not have a printed copy). Until you find the failure point, that is all I can tell you. A serial number will be helpful. You might also contact Elecraft support, and Dave W8FGU can likely help as well - he is the official contact for support on the legacy gear (K1, K2, KX1). 73, Don W3FPR On 6/21/2024 2:24 PM, Oscar Castillo wrote: hello everyone, Several years ago I bought my K2 and I have been very happy since then, but a month ago tragedy struck my life.

[Elecraft] KX2 mobile operation in Iceland
Thanks to those who called - the radio performed well, allowing me to work 3 continents from various parks in Iceland. The portability-to-features ratio of the KX2 can't be beat. Here is a video of it in action from the cramped quarters of a tiny rental car with a roof-mounted vertical. All activity was on 15, 17 and 20 meter CW. Some drone video precedes the radio portion: https://www.youtube.com/watch?v=mXBhKqoQLeA 73, John AE5X https://ae5x.blogspot.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K2 receive problem
I would suspect a bad relay associated the 40m lowpass filter -- or a bad solder connection to one of those relays. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco On 21/06/2024 3:55 pm, Jos Weitenberg wrote: I have the following problem with my K2, when I switch on the K2, sometimes the 40m band is deaf.
