Is there a way to control the transmit volume of the roger beep on my DX66? I bought it new about 3 years ago. Also, is there an internal tone adjustment for the beep?
Thanks Tech(s).

Nighthawk,
The tone and time of the roger beep on the DX66V can be changed as follows,
The Roger Beep tone is controlled by R181 which is 220K ohms.
For a higher tone try 150K to 200K ohms
For a lower tone try 270K to 2M ohms
The Roger Beep time is controlled by C134 which is 2.2uF@16V DC,
For longer time try 5uF or 10uF@16V DC.
For shorter time try 1uF@16V DC.
This is about all I can find that might be of help to you.
