[TenTec] Problem with 705 mic

[Edward Crawford]

There is a manual and schematic for the 705 mic available online as .pdf download at www.qsl.net/tentec/manuals<http://www.qsl.net/tentec/manuals> .
Hope you have already got it working from all the other suggestions.

  Subject: [TenTec] Problem with 705 mic


  I recently purchased a used 705 mic and it has a
  problem. Before I send it back, I wanted to see if
  there are some suggestions you folks might have on its
  repair.

  1. The mic came without a 9 volt battery, so I put one
  in and noticed the red transmit LED was on.

  2. Hitting both the PTT and lock switches on the base
  had no effect on turning it off.

  3. I opened the 4 pin connector and all looked good
  there (nothing shorted across PTT and GND pins)

  4. I put the mic on my omni 6 and when plugged in, it
  immediately kicks the rig into transmit and it does
  work, provide audio to the rig.

  When I open the base up later today, any suggestions
  on what to look for (don't have a schematic but can't
  imagine its too complex) ?

  Thanks in advance, Mark N1MT
