Re: [Elecraft] KAT500 failure
I've been at V1.75 firmware for quite some time but random lockups of the KAT500 started recently. It might be helpful knowing what command caused the problem.

Re: [Elecraft] K2 LCD and Backlight assembly problems
I resoldered the LED backlight devices by applying a small amount of pressure and resoldering each pin to make sure they were flush. This made the pins of the LCD flush with the PCB holes. I soldered it this way and it has worked. The LCD is working fine for my K2. Bruce, WB6IZG On Sat, Apr 10, 2021 at 6:05 AM Phil Le-Brun wrote: > Bruce, I am having the same issue.

[Elecraft] K3 with N connectors ?
Good morning all. Quick question. I recently bought a nice K3 ser # 89xx ,and it came with 2 N connectors on the back instead of the usual UHF SO-239.

Re: [Elecraft] K3 with N connectors ?
Larry, One local ham had me change the UHF SO239 connectors to N connectors because he does not trust the UHF connectors. I know he recently sold it, maybe it is the same one. It is easy to change them back to UHF type, but it definitely did not come from the factory that way. 73, Don W3FPR On 4/10/2021 11:44 AM, Larry Shapiro wrote: Good morning all. Quick question.

Re: [Elecraft] K3 with N connectors ?
My K3 Has all BNC connectors on the back. My preference as it travels some for Field Day, special events, etc. Makes it quicker and easier to set up and take down.

Re: [Elecraft] K3 with N connectors ?
Not to start a flame war about N vs UHF connectors, I prefer N and built my KPA500 and Hardrock 50 amps with them. My KX3 remains BNC, and any cable I have that is disconnected often is a BNC, sometimes with a BNC male to N female adapter, which are really common. No one but Hams still use PL259/SO239 connectors. The flange type four screw panel mount connectors are interchangeable. Change them back if you really want to. I now have really good interconnects with N connectors on my radios, switches and amplifiers. Since Hams don't like them, you can find really cheap, really good cables with N connectors at Hamfests, whenever they come back again. By good, I mean double shielded or heliax cable. It makes a big difference in terms of RF leakage compared to the 75% braid crap if you have multiple radios. I also make my own cables with real Amphenol (and other good brand) connectors. I've found surplus heliax cables from Cell Tower installs and test setups made of the really expensive Gore Teflon cable for pennies on the dollar. Real Amphenol silver plated connectors and adapters are common, also very reasonable. 73, Mark W7MLG On Sat, Apr 10, 2021 at 8:45 AM Larry Shapiro wrote: > > > Good morning all. > > Quick question. > I recently bought a nice K3 ser # 89xx ,and it came with 2 N connectors on > the back instead of the usual UHF SO-239. > The seller said it came from the factory that way. > Is this common ? > I have never seen this before. > Thank you, > Larry k6ro > > __ > 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 marklgoldb...@gmail.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

[Elecraft] Elecraft PA via Generator Power?
Anybody know, or have experience using an Elecraft PA (a 500 watt in my case) with a generator supplying AC power (a Honda 2 KW in my case)? I’ve not done it yet. Wanted to check to see if anyone else has prior experience before I end up blowing the final, or some such. The Honda flavor I have is the inverter styleand they have been known to put out a crappy “signal” at 60 Hz on occasion, not to mention fluctuations due to differing load at different moments.

[Elecraft] K2 LCD and Backlight assembly problems
Same here. I am about 75% through a K2 build and faced the same question. In my case the pins didn't quite make it to being flush with the bottom side of the board. Rather than pressing on the LCD and taking the risk of overstressing it, I flowed the solder from the bottom side and then checked with a DVM for a good connection between the topside LCD pins and the reverse side of the through-holes. All looked good, and the LCD works as it should on every test so far. This is my fourth K2. I did not have this problem with the previous builds, probably because those had integrated spacers. The separate spacer and LED pieces in the new kits may be higher by a fraction of a millimeter.
