[Elecraft] Elecraft CW Net Announcement
Good Evening, The weather has been seasonal: one day it's pouring rain with high winds, the next is sunny and warm, a day later it is snowing. The daffodils are open with a forecast of six inches of snow. Coyotes have returned a few times. The mountain beaver population represents a lot of calories. Hopefully a coyote - mountain beaver - rhododendron balance can be established. This week the sun was less active with inaccurate aim. Without the pummeling the ionosphere should induce less noise, maybe less QSB too. I expect active sunspots will return next week. Please join us on (or near): 14050 kHz at 2200z Sunday (3 PM PDT Sunday) 7047 kHz at 2330z Monday (4:30 PM PDT Sunday) 73, Kevin. KD5ONS - Mike - Mycroft - Adam Selene RIP 2076 A.

Re: [Elecraft] K3 and Kenwood MC-50 mike
Joe W4TV and Bob N6TV, I have been following discussion on the Elecraft and Elecraft K4 groups about MC-50/MC-60A and dynamic mike bias off (not being off, at times). I have been using a Kenwood MC-60A with my K4D, I plan on re-wiring my Heil GoldLine HC-4 taken from TenTec Orion II, and it looks like both mikes NEED the 1uf Tantalum Cap inline with the dynamic element as neither of those mikes have one. I also need to research my Heil Elite Pro HC-6 dynamic as "I think" it may have one. I have also "just" come to the understanding that MICBIAS and BIAS (pin 6) are TWO different "things" (correct me if I am wrong - reason for schematic, below) As I can see MIKEBIAS goes to Mike Pin 1 (J2). Thank you for pointing out that the Kenwood mike uses a different pin for the +8v bias (SO, Elecraft did not follow the Kenwood mike layout 100%) ?? I enjoy ALL your comments and advise. 73, steve WB3LGC On 4/9/22 09:57, Joe Subich, W4TV wrote: The MC50/MC50A/MC60A are a decent quality dynamic mic and a good match for the Elecraft transceivers.

In the world of audio, impedances have not been matched for half a century. Only those with blinders working in the world of RF have not gotten the message. RF impedances ARE matched. Audio impedances are NOT. Low-Z out, high Z in. K2 and K3 are done wrong. 73, Jim K9YC __ 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 and Kenwood MC-50 mike
I do have the K3 set for high impedance for the MC-50 (tap 1 in the mic selection menu) and then I switch to low impedance for the CM-500. In MENU:MIC SEL, tapping 1 toggles between high gain (dynamic mic) and low gain (electret mic) input levels. I tried low impedance with the MC-50 (yes I positioned the cable on the back of the mic correctly) and have settled on high impedance as it seemed to drive the K3 better when it is also set for high impedance. The high impedance setting of the MC-50 will have more output but the impedance mismatch may result is some frequency response issues. However, any frequency response problems may be addressed with the K3 TX EQ. I've found the MC-50 to be one of the best microphones ever made for modern radios. The MC50/MC50A/MC60A are a decent quality dynamic mic and a good match for the Elecraft transceivers. With the MC50A/MC60A one can (should) turn off the preamp in the base unless the 8 pin output jack is modified to move the +8V input from pin 5 to pin 6. 73, ...

Anyone have experience with this? Is it reasonable to use this with my K3. It is dynamic so no bias. I think the 600 ohm setting is what I am supposed to use. Do I need to change my equalization from what I use with my condenser mikes. Also I need to find a 4 pin jack to make an adaptor. I don't see anyone listing such a thing for sale. I will probably plug it into the back if I use it. Hi David. I have an MC-50 connected via a four pin to eight pin adapter I probably picked up off ebay. The idea at the time was swapping the mic between the K3 and the TS-520SE I have. I also have a CM-500 headset connected to the back panel which needs bias. The mic menu makes switching then rather easy. I do have different mic gain and compression settings between the two stored in the K3 utility.
