Fw: [ICOM] IC 775 DXII s-meter lamp flickering

[Vladimir V. Sidorov]

Mac,

 Concerning compression, you have to play not only with the Mic gain, but
 also with Drive level. Check different combinations of them both and you'll
 get a perfect signal, both compressed and with an excellent audio in the
 same time. The SM-20 matches the 775 perfectly.

 Honestly, I don't have any flickering neither at low, nor at high, altough
 as virtually all 775s do, my radio also delays the backlight at start up
 sometimes.

 73,

 Vladimir VE3IAE
