Can I add my "AMEN" to the thoughts below? I also use a CM500 after dialing in some EQ and processing and, especially, TX GATE for my rather noisy operating environment (its either the garage next to the laundry or no shack, so I make do!)
Although I do find it fun to test the AM capability of my receivers listening to ESSB guys. Some have enough energy past the carrier frequency that you can demodulate their signals in AM... All that bass creates a phantom carrier. These guys were ahead of their time in the unintended implementation of MDCL technology (Modulation Dependent Carrier Level, a way of saving electricity at AM stations newly blessed by the FCC for broadcasters). My station on air sound may not be very "manly", as an ESSB guy once told me on the air, but in most cases, the other guy tends to copy me well... And that is what this game is all about, right? -lu-w4lt- K3/P3/K1 ====================== Message: 18 Date: Tue, 19 Jun 2012 12:39:50 -0700 From: Jim Brown <j...@audiosystemsgroup.com> Subject: Re: [Elecraft] more Bass in K3 with PR-40 To: elecraft@mailman.qth.net Message-ID: <4fe0d586.3050...@audiosystemsgroup.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Second, while I don't know the specifics of the Heil mics, I'd guess that there's a strong presence peak around 3 kHz to compensate the rolloff produced by crystal filters in both the TX and the RX. This is also good engineering practice, but taken too far can be too bright. The easy solution in the K3 is to use some cut on the highest (and perhaps next to highest) filters. Third, a little proximity effect goes a long way, and proximity effect is VERY sensitive to distance. Proximity effect also increases breath pops and handling noise. When you work a mic TOO close, proximity effect will cause the lows to get louder and softer with very small changes in distance from your mouth. I use a Yamaha CM500, and keep it a few inches above and to the side of my mouth so that breath pops don't hit it (and so that I can swig coffee). I have the TXEQ and compression adjusted for competitive contesting and DX audio, and I get reports of great audio. Like Joe and Scott, I'm a retired broadcast and pro audio engineer, and I own several dozen pro mics, but I use the $40 Yamaha in my ham station. ______________________________________________________________ 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
