Facts About Microphones - Part 3

This is the RAIN Hamcast Podcast #113, posted 04-20-24. Voiced by Will Rogers/K5WLR.

[The running time for this RAIN Hamcast Podcast is 12M00S there is a station ID at 06M05S then timer resets approximately every 3 minutes.]

Bob Heil/K9EID was the only microphone manufacturer to be inducted into the Rock'n'Roll Hall of Fame. Bob passed on February 28, 2024. This is our third and final excerpt from Hap Holly/KC9RP's hour-long conversation with Bob conducted in 2018. At the end of part two of Hap's interview, Bob talked about the importance of perimetric equalization in the audio chain of your ham station and computer. I'm using a Heil HM12 as you hear this script.

That's it for our tribute to the late Bob Heil/K9EID, who sold well over 100,000 Heil Sound microphones during his illustrious audio career. If you open up a modern-day ham transceiver, chances are you'll find some of Bob's handywork in the audio section; and you may discover his HC-3 or HC-4 elements in the microphone plugged into your base or mobile transceiver. 73 Bob, you will be sorely missed.

No one connected with RAIN, the Radio Amateur Information Network, receives compensation from or for his/her efforts, and that includes Hap Holly/KC9RP, who was Founder/Producer of the RAIN Report from 1990-2019; and the RAIN Hamcast Podcast since 2019. hap recorded the Dayton Hamvention forums annually with help from long-time friend and the man behind the 160 Meter Gateway Radio Newsletter, Vern Jackson/WA0RCR. The RAIN Report archive consists of many excerpts from those Hamvention forum recordings. And the Classic RAIN Ham Cast features previously unreleased ham programming by Hap, who spends some 5 hours producing the biweekly Classic RAIN Ham Cast. Now in the spirit of full disclosure: For a few of the last years of the RAIN Report DARA (the Dayton Amateur Radio Assoc.) And NSRC (the North Shore Radio Club (Highland Park, IL) helped subsidize RAIN. There is no such funding today. Having said that, the Radio Amateur Information Network is not a tax deductible or tax exempt organization. Hope you can help.
