BULLETIN # 15
MODEL: VOX-3
SUBJECT: VOX SENSITIVITY WITH MC-50
                                                      
There have been a few instances of improper VOX operation when
the MC-50 microphone is used. The sensitivity of the VOX-3 may be
increased by removing R-4 and connecting R-3 directly to ground.
Also install a 220mfd 25VDC electrolytic in parallel with C-6.
(These parts are all on the X54-1010-00 board.) If the VOX delay
is insufficient, change C-10 (on the X54-0001-00 board) from
3.3mfd 50VDC to a lOmfd 50VDC capaciter.
