Re: [Elecraft] K3 - Proset K2 Mic Frequency Response
To avoid any possible doping scandal and reduce any inflammatory outcomes perhaps they should use a catabolic chamber. 73, Pete F5VNB Bob wrote: Is it a chamber lined with well known high priced and overpaid athletes? 73, Bob K2TK Bill NY9H wrote: ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 - Proset K2 Mic Frequency Response
In a message of 3 June 2008, [EMAIL PROTECTED] said ... Last week I posted a message asking for info about the frequency response of the mic in the Proset K2. I didn't receive any replies but I've now heard from Bob Heil that it's 40 Hz - 12 kHz. Just thought I'd pass it on in case it's useful to anyone. Yes, Geoff, that is indeed very useful and interesting. In the absence of a graph one has to assume that the response is substantially flat, falling off by 6dB at 40Hz and at 12kHz. 73 -- David G4DMP Leeds, England, UK -- ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 - Proset K2 Mic Frequency Response
David, As Jim Brown stated a day or 2 ago, just the frequency range is not sufficient information. The response curve used to be posted on the Elecraft website, and it was *not* flat. 73, Don W3FPR David Pratt wrote: In a message of 3 June 2008, [EMAIL PROTECTED] said ...

Re: [Elecraft] K3 - Proset K2 Mic Frequency Response
nice chart looks like the results are from a Bruel Kjaer. But can you explain what sort of chamber was used, maybe it is a left over from the psychedelic days ... Shure Bros , AKG Sennheiser use an Anechoic... (n. anechoic chamber is a shielded room designed to attenuate waves) No sure what tests do you do in an anabolic chamberbut i don't want to do the testing. Must be a Southern Illinois thing. First saw this about 5 years ago in a CQ magazine review.

Re: [Elecraft] K3 - Proset K2 Mic Frequency Response
Frequency response curve looks reasonable for a communications mic, but at what distance was the curve run? And what fundamental microphone types are these mics -- omni, cardioid, hypercardioid, supercardioid, bidirectional? VERY important. Anabolic is a new one one me too! :) Most microphone measurements are done in anechoic chambers. I'm saving a copy of that graph to use in my lectures! 73, Jim Brown K9YC On Fri, 06 Jun 2008 17:30:42 -0500, Bill NY9H wrote: nice chart looks like the results are from a Bruel Kjaer.

ALL ham mics (as well as many pro mics) meet that VERY broad description -- it tells us nothing! To be meaningful, there's must be a +/- dB tolerance, AND you need to see a graph of the frequency response. To understand ham mics and their frequency response, study pages 41-45 in http://audiosystemsgroup.com/HamInterfacing.pdf Also, study Appendix 6 of http://audiosystemsgroup.com/RFI-Ham.pdf 73, Jim Brown K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
