Re: [TenTec] Question regarding Omni VI+ on SSB

["A. Sewell" <n5na@att.net>]

With all the TT705 mic discussion I pulled my instruction sheet out to 
see just what it has to say.

"The Model 705 incorporates a momentary type Push-To-Talk (PTT) button 
(gray), a Push-On, Push-Off locking type button (black), electronic 
circuitry to switch the microphone on, a signal amplifier that adds 13dB 
of gain to the output level, an attached output cable and a battery 
compartment for a 9 volt alkaline battery"

SPECIFICATIONS
.........stuff skipped
ELECTRONICS:  C-Mos PTT switch, C-Mos signal amplifier, NPN T/R transistor.
CURRENT REQUIRED:  Receive mode:  Less than 2 microamperes.
                Transmit mode:  2 milliamperes typical, with 9 volt 
battery.

73,

Alan  N5NA
