In some cases it was necessary to "find" a polarizing voltage. This worked fine, with a ground pin, mic audio, PTT, and the polarizing voltage. In order to get this voltage, TenTec went to the 4 pin connector that was very common at the time. This mic element required a small (about 8 to 12 volts at less than 1 ma) polarizing voltage. The 214 microphone looks exactly the same as the 215 (externally), but inside is an elecret condenser mic element. Later models were more of a Chocolate Brown. In addition, there were 2 different color schemes. The coiled cord worked better with the Omni, but the Triton and Argonaut need a "non coiled" cord to reach the connector in the back.
#TEN TEC TRITON IV MODS SERIES#
Some time after the Triton series of rigs, TenTec came out with the 215 PC, which had a plug and a coiled cord on it. The 215 P, had a 1/4 inch stereo plug on it (P for Plug), that was used with the Trition, Argonaut, Omni, etc. The 215 is the number for the plain mic and die cast base. The EV 729 was offered by Electro-Voice for a few years, with Al Kahn having TenTec manufacture the model and warranty repairs/parts for the EV 729 model. The EV 727 microphone was sold OEM to Drake with a Hi-Z ceramic element in 1960s and early 1970s for their 4-line radios.
When Al Kahn left Electrovoice and formed TenTec, he took with him the rights (and I think even the dies, etc.) for the EV 727 “Banana“ Microphone. With 8.5 foot shielded cable with additional red and black conductors.Įlectro-Voice Commercial Sound Catalog, #132A The Electro-Voice 727SR (shown above) additionally features a PTT leaf type switch. It is mounted on a sturdy diecast desk stand for table-top use. The Electro-Voice 727 is all purpose ceramic omnidirectional desk mic. I also used a cheap Astatic mic sold for CB use and commonly available at truck stops or Walmart which sounded surprisingly good with the Omni-C.īasically one of these with the connector rewired for Kenwood 4 pin and then the adapter cable above when I used it with the Omni-C In terms of microphones, there are a lot of choices but I liked the sound of a Shure 444D for general use and a D104 with a FET buffer for DX use with its high frequency emphasis.
Here's the kind of cable I'm talking about: That's what I ran when I owned an Omni-C, a couple of my rigs on the operating table at the time were Kenwoods with the 4 pin mic connector so I just kept a D104 and a Shure 444D with the Kenwood connector and used an adapter cable for the Ten Tec. But there are also adapter cables made for many common microphone styles such as converting from a Kenwood 4 pin or 8 pin connector to 1/4" TRS, adapters exist for most of the major vendors like Yaesu or Icom as well.
