Re: [Elecraft] Flaky mic jack on KX3
You could try to replace the jack yourself. It's an uncommon size (TRRS), but Philmore #70-088 should work: https://shopintertex.com/philmore-70-088-chassis-mt-female-jack-3-5mm-4-conductor.html?gclid=Cj0KCQjwub-HBhCyARIsAPctr7y3_kdB6IO7H2ehsuk2J5Ogwgfu2jpcBB2wN-453t_tS2F43g2z7JoaAlkZEALw_wcB 73 Lyn, W0LEN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Walter Underwood Sent: Thursday, July 15, 2021 5:51 PM To: Reflector Elecraft Subject: [Elecraft] Flaky mic jack on KX3 The mic jack on my KX3 is not making good contact with my MH3.

[Elecraft] Nabble down
Nabble has been unavailable (DNS error) to read the kist for a few days. Temporary glitch or is it gone forever?

Re: [Elecraft] Broke my K2 :(
You can radically mitigate the issue by using a secondary container for that which you'll use in a week or so, and only open the quart/gallon to dispense to working container. I have dry argon in my shack to purge gas space in any container that is hygroscopic or oxidizes in presence of atmosphere. I use 99.9 for cleaning all boards (flush after "scrub").Where allowed, I follow up with RODI water flush and forced air drying.

Re: [Elecraft] Broke my K2 :(
Yep. I worked at an company where we had some boards with very high impedance circuitry (with the usual guard rings etc.). We tried many things trying to get wave soldering and aqueous flux to work, but no amount of rinsing washing got the surface conductivity down to where we needed it . We wound up using mildly active rosin based flux on those boards. The diluent in 70 and 91% isopropanol is water. 99.9% isopropanol will only be 99.9% when you first open the bottle. It starts aggressively absorbing water from the atmosphere as soon as exposed. Lou W7HV On Thursday, July 15, 2021, 4:06:54 AM MDT, Alan Bloom wrote: Don is exactly right about this.

Re: [Elecraft] K2 Only 30-metre Band Works
Don, I borrowed a couple of new relays from my KAT2 kit. I installed K1 and K2 with the correct orientation this time. This immediately resolved all transmit and receive problems. I have pushed on to successfully build the KNB2, KBT2 and I'm now working on the KSB2. No further problems have been found. The K160RX, KAT2 and KIO2 will follow these. My replacement relays are on the way to me from Elecraft. I'm having fun again. I have downloaded Spectrogram and I'll use it for filter alignment as soon as I complete the KSB2 just to be thorough but I'm already happy with the way the K2 is working. I've also bookmarked your web page since I see lots of useful articles. This email list sure is a useful resource. 73, Murray VA1CQ -- This email has been checked for viruses by AVG. https://www.avg.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

I generally do not recommend cleaning boards, solder flux is non-conductive and will normally not cause a problem. I only clean when the solder flux residue is really nasty as might occur with Kester 44 solder. Use of a solder with a mildly reactive flux (Kester 385) will reduce the need for cleaning the board - there is almost no residue. If you do choose to clean the board, make sure your cleaning work is complete. While solder flux is non-conductive, the flux plus the cleaner may be conductive leading to resistive leakage paths. If you can see any white stuff on the board, you have not done a complete job. 73, Don W3FPR On 7/14/2021 6:41 PM, Peter Eijlander (PA0PJE) wrote: Yes Jerry, isopropyl alcohol does this!
