Lu, if you have access to an SDR receiver that can record it's output on a PC, it might be easier that using a noise source.
When comparing several microphones and headsets on my K3, I used a Perseus SDR to play back the results for A/B/C/D comparison in order to pick the best equaliser/mic combination. The saved files from the Perseus were labelled to match the microphone and can be played back very easily, in addition, recording a wide chunk of frequency means the bandwidth can easily be checked if that might be an issue. 73 Dave ______________________________________________________________ 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
