Hi Everyone,

I have a Model 705 Desk Mic for sale. Bought this new several years ago 
but sold the rig for which it was intended. Never used by me except to 
check that it worked when I received it. Condition is 9.9  (would be a 
10.0 but it is technically a 'used' item.

I do not have the original packaging or instructions any longer. The 
specs below come from  the Ten Tec Wiki:




The Ten-Tec Model 705 is an Electret desk microphone designed for use as 
a station microphone in commercial and amateur radio communications and 
in public address and paging installations. The microphone consists of a 
base section and flexible gooseneck mounted microphone. 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 13 dB of gain to 
the output level, an attached output cable and a battery compartment for 
a 9 volt alkaline battery. The PTT circuitry allows switching 
transmitters and/or transceivers, that have a low voltage positive T/R 
lines, into transmit mode. A light emitting diode in the base signals 
the transmit mode.
