Re: [Elecraft] Knowles HC-3 Mic Element Replacement For Heil HC-5
I agree with Fred (Skip)- electret mic elements are hard to beat, especially with Elecraft rigs or others which have frequency compensation. The electret elements are small and inexpensive. With their flat responses, they will need some equalization for use as ham mics - reduced low frequency response mainly. If you want a boost in the 3000 to 3500 Hz, equalization Will do it. They do need bias to function, but that is no problem with Elecraft gear, just turn bias on in the menu. 73, Don W3FPR On 3/21/2022 6:15 PM, Fred Jensen wrote: "It would be great if these elements could be modified to perform better" Au contraire, Tony. They were designed for a particular purpose and they perform very well for that purpose. Unfortunately, that purpose is just not normally found in ham radio. It is very hard to beat electret mics. They're cheap, tiny, have flat responses, and tend to be immune to breath-blasts if you talk across them rather than into them. Some mics [dynamic and especially ribbon velocity mics] will emphasize the lows as you move close to them. The classic RCA 44-BX series [fairly large, prismatic-shaped one, Johnny Carson used to have one on his desk] was particularly afflicted ... when I was 17 and on AM, I sounded like I was 17. Crawl up very close to the -BX and I sounded like Morgan Freeman playing God in "Bruce Almighty." There is little speech information in the low frequencies but a lot of power. Electrets are generally less prone to this. Most of today's rigs provide the DC bias electrets require right on the mic connector. __ 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] De-soldering Tool Recommendations?
As a valuable side note, the Hakko 808 makes an excellent enameled wire stripping/tinning tool for toroids and similar. I prop my up vertically, melt a blob of solder in the tip, plunge the enameled wire into the tip through the solder blob, wait a second or two and activate the vacuum. The excess solder is whisked away along with the enamel insulation leaving a brightly tinned and stripped wire. I believe I’ve actually used my 808 more for this than desoldering! It actually made building the toroids for a K2, T1, and other projects fun. Consider this valuable additional function as you justify the cost of a similar tool.
