Earl,

If you're experiencing low audio with your current headphones check their
impedance.  The K2 is designed for 32 ohms and will produce low output with
the typical 4-8 ohm "communications" phones.  I initially experienced the
same problem with my K2.  I now use a pair of Labtec 820 phones and rarely
move the AF gain beyond the 9 o'clock position.

If you experience the same low audio problem through the speaker then the
most likely problem is crosswiring at the remote speaker jack.
