Byron, I use the Heil ProSet7 with my K3, and it works very well.
On the earphone side, I think the drivers are optimized for communications, and that is fine. They are very sensitive, and I rarely operate with the AF gain beyond about 9 o'clock unless I close down the filters in CW mode. The passive noise-reduction via the fit of the ear pads is outstanding. I can barely hear when the KPA500 fan commences to roaring. Regarding the microphone, I went with the HC7 dynamic over the iC electret element because the HC7 seemed to me to have better built-in EQ that would be favorable for good communications audio, than the iC. The HC7 requires a bit more gain, but the K3 can easily provide it. I connect via the front-panel Mic connector on the K3, and use the built-in K3 mic preamp for the front panel microphone connector that is accessible via the menu options: Menu > MIC SEL : FP.L (with the preamp engaged by pressing the "7" keypad key while in the above mode. I find that a front-panel "Mic" setting of about 50 works very well, and I generally use a front-panel compression setting (CMP) of about 18. Close-talking the microphone will probably be required, unless you naturally speak loudly. I do not. As a starting point for the EQ, I would suggest that you begin with the following settings: 1 -16 2 -9 3 -4 4 -6 5 -2 6 +5 7 +10 8 +10 The resulting tx audio is very articulate, and sounds good to my ear and evidently to others who had commented favorably on the audio quality without being asked. I happen to be a big fan of the Heil HC5 element, which sadly, is no longer being manufactured, and with some significant EQ, this HC7 can be made to sound pretty similar. This is a very subjective topic though, so some experimentation is in order for your particular voice and personal preferences. Have fun! 73, Dale, WA8SRA I went with the > Has anyone real experience with the ProSet 7 and the K3S? > My vintage ProSet is making noises in one ear and I wonder how good the > Pro7 is with SSB and CW. > > 72, Byron > > ______________________________________________________________ > 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 d...@lightstream.net > ______________________________________________________________ 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
