[Elecraft] elecraft-dev list shut down?
The last message posted to the elecraft-dev list was in January. I tried posting a few days ago and my post never appeared. Has that reflector been shut down? If it has, what is the appropriate forum for asking K3/K3S related programming questions? Thanks. -- Art Greenberg WA2LLN a...@artg.tv __ 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] K3 malfunction
Follow-up: It looks like one of the KSYN3A synthesizers went toes up. The little green LED on synth #2 (sub rx) was on, but not the one on synth #1 (main rx). When I swapped them, the illuminated LED followed the (presumed) working synth. With just the one working synth installed for the main rx, the radio came to life, and the response to the OM command has the "V" back in it. -- Art Greenberg WA2LLN a...@artg.tv On Thu, Oct 22, 2020, at 17:09, Art Greenberg wrote: > My K3/100 S/N 6522 was fine yesterday.

Re: [Elecraft] Self-fusing liquid electrical tape
Yeah, maybe I'm one of the exceptions. I just used 20 of them to build a lightning ground system for a new tower install.

Re: [Elecraft] Quiet Ductless HVAC System
Albert, I have an 18,000 BTU mini-split cooling my wood shop and radio shack. I started with a high-end Lennox mini-split. When it died out of warranty I could not justify the extra cost to go with the same model over a Mitsubishi. No detectable RFI from either. The Lennox was MS7-HO-18P outside and MS7-HI-18P inside. I'll have to get back to you with model numbers for the Mitsubishi. I cannot locate that information at the moment. -- Art Greenberg WA2LLN a...@artg.tv On Wed, May 27, 2020, at 07:09, Albert Reynolds wrote: > Does anyone have suggestions for an RF quiet ductless, also called a "mini > split" heat pump system.

Re: [Elecraft] SS Amp
I have the 1.5K-FA. I like it. I am not heavily into contesting and I'm not a competitive DXer. Yes, it's less expensive than the KPA1500. It also doesn't integrate as well with the K3. It doesn't control the K3's output power when switching between standby and operate. One needs to remember to do that, especially when switching into operate mode on the amp - massive overdrive isn't pretty and could damage the amplifier. It doesn't remote as well as the KPA1500, either. It comes with a software control panel that runs on Windows. I use VNC to control the amp when operating remote.

I am looking at the SPE 1.5K-FA which is about $1000 less. I like the fact that it has inputs for two radios and 4 antenna connections. Plus the power supply is built into the same box. I know the response from this list will be pro Elecraft but any constructive or informative comments would be appreciated.

Re: [Elecraft] Resistor and capacitor installation techniques: trim before or after soldering?
I guess if you're building something that goes into a spacecraft or is life support equipment, you want to do everything you can to make the product as reliable as possible. In most cases, ham gear, especially hand assembled ham gear, doesn't fall into that category. Mass produced through-hole assembly where the PCB is wave soldered requires the parts to be held in place and leads trimmed prior to soldering. I recall a "staking" tool that would flatten the component lead very close to the PCB and trim off the excess in one operation. Replacing parts where the components were staked in is a PITA. -- Art Greenberg WA2LLN a...@artg.tv On Sun, Mar 25, 2018, at 12:18, Don Wilhelm wrote: > I agree, the stated NASA "method" does amaze me. > First, the K2 is not likely to go a space journey. > > Components with pre-cut leads may require 3 hands.

Ed, I presume you're running some I/Q processing with the LP-PAN. Are you doing that while running a computer based digital mode? Are you using a separate audio interface for the RX TX audio in those modes?
