Re: [Elecraft] K4 Delivery?
I guess we need a "no troll" policy as well. A mis-leading subject line. No Elecraft content in the body of the email. A link that leads to a politicized article. That is the definition of a troll email. Nothing about the K4 to be found...

I can find tons of media information specifically on the Bobcat Fire with almost daily datelines when I do a Google search, and I know from personal experience with wildfires here in southern Arizona that agencies have to prioritize literally on an hour by hour basis how and where they deploy scarce resources. Slurry bombers are about the only effective countermeasures in rough terrain (and even then only partially), since sending fire crews into those areas is pure and simple murder. Here where I live (dry grass, dry trees, hilly terrain) the aircraft (slurry bombers, helicopter water drops) try to slow the fires while the fire crews mostly just dig in their heels and try to save the homes ... and there isn't much point in them doing so until the homes are actually threatened. The fire that whipped through this area in 2011 burned EVERYTHING within about 50 feet of my home, but the fire crews wouldn't back off and they saved the house. If you can find the Google Earth satellite pictures from July 2011 you can see what I mean (my .kml info is available from QRZ.com page) ... everything is black except for a cone where my house is at the pointed end of the cone. With 4 million acres on fire in California within a short period of time I think it's unrealistic of you to think that there will ever be enough resources in reserve to cover everything in a situation like that ... at least not when you would like.

I am completely floored by the complete destruction of Bob's place. Bob, I don't know if you're a believer, but I for one am praying for strength for you, my friend. My impression of the Bobcat fire here in Los Angeles, which got to within 2 miles from me and is still burning 38 days later, is similar to Bob's: fire agencies simply let it burn for days without any urgency whatsoever, letting it advance into backyards in the northernmost reaches of Arcadia and Monrovia before kicking into firefighting high gear at the last possible second. In strangely similar fashion, the news media never really reported with any energy on the Bobcat fire. I still can't understand the almost total ignoring of this fire for so long. So I resonated with Bob on this point, and for this reason I refute W6GJB's claim that resources assigned to southern California deprived northern California of the same. It seems that *nobody* had the resources they needed. What a shame. Hang in there, Bob. Please let us know if you've started a gofundme page or something like that.

[Elecraft] Much Better Than Spectrogram

Re: [Elecraft] SOLVED Radiosport MH-350ADJ with K2?
Thanks Don, I already knew the basics of a resistor between pin 1 and 6 from a simple google search, but I suspected there was more to the story with the Radiosport headset. And there is. After conferring with Dave, WI6R and super helpful owner, there is already a resistor inside the CS6-ELK cable and two dip switches to control whether to provide bias to the mic element. Some blocking and filtering is also part of the circuit. The only thing I needed to do to the radio was to wire wrap from pin 6 to pin 5 on the K2 mic header to provide 5V at the mic jack pin 5 in the fashion of a Kenwood radio. Pin 6 was not connected at the mic jack. The CS6-ELK cable needs the provided bias to act like a Kenwood, not a K2. Then set the DIP switches and it works great. Now 1 cable and 1 mic element for both the K2 and K3! I've copied the circuit image inline, I just don't know if the reflector filters them out. If so, be happy to email it direct. Yet another reason why the RS headsets are so darn good and well thought out. 73, Steve W1SRD On 7/26/2020 4:39 PM, Don Wilhelm wrote: Steve, I am not familiar with that particular mic element, but -- If that is a dynamic mic element, no resistor should be used. If it is an electret type, the normal 5.6k resistor should work fine, it is not critical - anything between 5.6k and 10k will do fine. 73, Don W3FPR On 7/26/2020 7:01 PM, Steve Dyer W1SRD via Elecraft wrote: Is anyone using this mic element with the K2?

[Elecraft] For Sale: K2 DSP Filter KDSP2
I dug out my K2 during shack cleanup and was going to sell it but it's been great fun to play with and decided to keep it. Maybe a bit of nostalgia and also remembering pain and joy of the build process :-). Selling just the KDSP2. It works great, but I prefer the sound and simplicity of the KAF2. Side by side the KDSP2 compared very favorably with a Timewave DSP-599zx with v5 firmware. Includes the manual, control board headers and mounting hardware.

Suddenly starts giving intermittent HiCur messages yesterday. Tore out KPA100 and KSB2. -Occurs on all bands tested (40, 30, 20, 17, 12, 10) (no dummy load, but checked R with Rig Experts AA-54 and tested close to 50 ohm points with almost no Z). -Happens with Tune or keying at all power settings -Message displays at key-up when hand keying/tune, will happen quickly with keyer and then fold-back power. -Cal Cur is 3.5A -Measured power output with external wattmeter (SX-200) and power tracked fairly closely to setting -Will not happen if power is lowered to -Checked power supply output voltage with DMM and it matches the K2 display voltage +.4V. PS is set to 14V. -Current draw on 40M @ 12W is 2.3A 13.1V (.5V drop), 17M @ 12W = 3.44A 12.9V (.7V drop) -On 40M Q7 Base is .611V Q8 is .612V -Completely disassembled and visually inspected all solder with magnifying glass and re-heated common transformers and chokes in final. Re-seated IOC and MCU (lifted slightly and pushed back into socket). -Checked T4 windings -Have done the DC voltage tests suggested in the various threads about HiCurr and everything looks normal. Have another few days here, would be nice to get back on the air if anyone has an idea. 73, Steve W1SRD/KH6 __ 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
