Jim,

Thanks for the reply. I had known that Al Kahn had founded Electro-Voice. I wish I had the chance to talk with him. My dad was a huge electro-voice fan and he and his best friend from High School, Bart Locanthy, had both designed and built their own sound systems, starting back then. . When Bart Locanthy (of JBL and Pioneer) came to visit after Dad had completed his last speaker enclosures, Dad was like a little kid because Locanthy just sat in the chair and smiled. Talk about hams being taken up by their hobby.

Anyway, Yes I like my Jupiter a lot. And I do get complements on my audio using a Shure 444 but only after playing with the levels and balance until I got it right, to me at least. I am in quandary regarding mikes. I like the 444 and do get great reports on my audio. I also have a HCL-4 element mounted in an unknown mike. I have gotten good reports with that mike when I was using it on my Kenwood but have not yet rewired it for the Jupiter. After operating in several venues with headset and mike combos, including W1AW in Newington, and during Field Day, that also sounds good, so to speak.. What can I say. What else can I do. I plan to re-plug (more properly) the HCL-4 mike, consider the new Heil cartridge, and probably get the Yamaha headset. THEN I can decide what works best for me. Thank you for your suggestions.

John / WA1JG

Sorry, I sold my last Ten Tec transceiver several years ago (but still
use Titans and a Herc II). Ten Tec's audio inputs have always been
pretty good -- remember that Al Kahn, the engineer who founded the
company did so with his returns from the sale of Electro-Voice, one of
the finest pro microphone and loudspeaker companies on the planet at the
time. In general, just about any decent mic will work just fine with any
Ten Tec rig I've seen with the exception of a BALANCED professional
electret mic, which can't easily be made to work with ANY unbalanced
inputs.

So I'd say, by all means go ahead, following the guidelines in my Ham
Interfacing Power Point slides.  And while there has been discussion of
using a pad (resistive attenuator), I'd be very surprised if it is
needed.  It was NOT needed with an FT1000MP, which has a very sensitive
mic input, and had be turned very close to zero with a CM500. But when I
did that for testing with a very good engineer and serious contester
listening only three miles away, he gave me a clean bill of health.

One other VERY important point. With any mic like this, it's good to
keep it away from your mouth to avoid breath pops and bass boost. That
spacing will also reduce the need for a pad. I wear mine with the mic
about 2 inches above and 2 inches to the side of my mouth. Sound-wise it
would be fine at that spacing below the mouth, but you can't munch or
drink coffee with the mic down there, so I settled on the high and to
the side position. :)
