[Elecraft] Another way to pass time waiting for my K4 - building a K2
I was late getting in the queue -- I ordered it after I flew home on the Tuesday after Dayton 2019. It'll be interesting to see when it comes and what serial number I get. So I bought a K2 and am now building it. I was on the verge of doing that in 2007 when the K3 was announced so I built the K3 instead. The K2's time has finally come. I just got to the first test stage. I don't know what I'll do with it once it's built. Sell it, keep it as a loaner for new HF ops in one of my clubs, who knows? I love the smell of rosin in the morning. 73 and thanks for listening -- Carl WS7L __ 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

If you have any of the remaining screws then take one to the hardware store when you go. They will do a perfect match for you. They use an aluminum template folds referred to as a Screw Checker to make sure it is correct. The sis not an “eyeball exercise.” There is nothing about that screw usage that is demanding in terms of material science, etc. Regards -Hal WB6NNR (I was a design engineer for 35 years….You will be fine) > On Apr 13, 2021, at 9:36 AM, Tommy Judson via Elecraft > wrote: > > Make a bad purchase good? > Bought a KX-2 off the internet and have found that it is missing several of > the screws that held the end plates on.

Re: [Elecraft] Elecraft Digest, Vol 204, Issue 6
Make a bad purchase good? Bought a KX-2 off the internet and have found that it is missing several of the screws that held the end plates on. Asked about that and the seller said he tried to put some sort of protective end plates onto the radio but couldn’t do it so threw them away and put the original end plates back on. What concerns me about just going to the hardware store and getting more screws (that might not be the proper thread/length) is I think two of the screws held the final output transistors onto that end plate which I assume was for that end plate to act as a heatsink. The seller said he used the radio and it seemed to be ok but I am concerned about the lack of heatsink/output transistor integrity and any possible damage. Maybe I’m on the wrong track here because of never seeing a KX-2 before. The radio looks good - no scratches or dings and the seller told me to find out what is needed to be done to fix it and he’d send that to me. Any help on this concern would be appreciated. F.Y.I - the serial number is 03742 and the Firmware is REF5. Sure would like to know when this radio was made and if this is the latest firmware. 73, Tommy, N5CTC > On Apr 12, 2021, at 9:38 AM, elecraft-requ...@mailman.qth.net wrote: > > Send Elecraft mailing list submissions to > elecraft@mailman.qth.net > ___ __ 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] KX2 Questions
Hi Dave, I don't have those numbers in front of me, but wanted to offer that I have a KX2 and love it. The learning curve for me was pretty steep in terms of the menus etc, but YMMV. I run almost exclusively CW, and find it performs very well in that mode. I would strongly recommend the book that Elecraft offers for this rig, as it is much more detailed than the basic user manual. 72 es stay well!

[Elecraft] KX2 Questions
I am a long time CW operator, but new to this group. I am considering purchasing a KX2, but I have been unable to find answers to these two questions:1. What is the approximate current draw for the KX2 on transmit at 5 watts CW?2. What is the narrowest receiver filter width on CW? Many thanks in advance for any help with these questions.73 es 72,DaveK8RXB Sent from my Galaxy __ 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
