[TenTec] Scout 555 MIC Gain Question...

[Ben Hall]

Good evening all!

I inherited a Ten-Tec Scout 555 transceiver from my father-in-law.  He 
regularly used it on 20 and 40 mobile before he passed away, so I 
believe it is in good working order.

Certainly, the receiver on it seems to work great!

The manual notes to turn up the MIC gain until the ALC light flashes on 
voice peaks.  With the standard Ten-Tec hand-held microphone, I have to 
have the MIC gain all the way up and then speak extremely loudly (enough 
to irritate the XYL in the other room!) to get the ALC light to flicker 
on voice peaks.

Even though my father-in-law used this regularly, I wondered if perhaps 
the MIC was going bad.  So, I connected up a Ten-Tec model 705 
desk-style microphone.  I get the same behavior - need to speak very 
loudly with the mic gain all the way up to get the ALC light to flicker 
on voice peaks.

So my question is this - is this normal behavior for a Scout, or do I 
need to open it up and see if something is goofy in the audio input 
circuitry around U6-B?

thanks much and 73,
