Carl,
My Model 705 manual says "The standard Model 705 may be externally powered if
desired. A source of 7 to 14 volts DC capable of delivering at least 5
milliamperes is required. If no external power source is contemplated, or when
model 705a (a similar, but phone-plug fixed mic) is used, a 9 volt alkaline
type battery (not supplied) must be installed."
The list of Ten-Tec radios indicated as wired for the 705 did not include the
Delta or Delta II, but that may have been because the instructions may have
been writen before the D-II's existence--it doesn't refer to the Omni VI,
either.
As for the Corsairs, Clark, the 705/705a manual stats that "with a minor
resistor change in the Corsairs, the standard unit (705) may be powered from
the transceiver without the need for a 9 volt battery."
My Delta II manual says in the spec sheet: "polarizing voltage is available for
electeret types." The front panel connector is as I described in a previous
post this morning, pin4 =+4 VDC, pin2=GND, pin1=Mic; pin3=PTT.
Your Delta II should have voltage at pin 4, Carl. You shouldn't have to run
off the battery.
