Re: [Elecraft] Removing/connecting PL-259s
Folks, let's close the PL259 threads now in the interest of reducing list email overload for the rest of our readers. 73, Eric moderator, even on my days off.. elecraft.com _..._ > On Feb 17, 2019, at 8:58 AM, wrote: > > I had that happen once too many years ago with an Amphenol PL-259.

Re: [Elecraft] Removing/connecting PL-259s
I had that happen once too many years ago with an Amphenol PL-259. Since then I make sure that they fit together before soldering!

It's not too bad since I'm mostly a CW operator and don't usually have a lot of other peripherals, SDR, computer, etc. connected to the K3. BTW, I don't trust the Amphenol name particularly after getting a bad plug that wouldn't thread correctly (only realized after soldering the thing on the coax and trying to use it. Arggh!). Amphenol is offshore product now. 73, Drew AF2Z __ 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] Removing/connecting PL-259s
I use a single PL-259 for all the transmitting antennas as a lightning disconnect. I can attest to the fact that trouble ensues if I forget to tighten it with the pliers. I crashed my computer during the contest today. Twice, before I caught on. 73, Scott K9MA On 2/16/2019 21:40, Drew AF2Z wrote: No, a bit paranoid perhaps but I disconnect the rig entirely, including p/s cable.

Re: [Elecraft] Removing/connecting PL-259s
Don et al: That is the best idea! Plus if one has a adequate outside lightning protection system, properly bonded to the AC mains, and then disconnects inside where they use a coax switch with gas discharge tubes and a grounding position, they are negating part of the system protection. 73 Bob, K4TAX On 2/16/2019 5:24 PM, Don Wilhelm wrote: Drew and all, I have changed the subject line to something more akin to the current discussion.
