[Icom] Low transmitted audio on the IC-725

Sat, 9 Nov 2002 08:43:36 +0100

Hi Adam,

Many thanks for your very kind support!

I really would appreciate a scan of the applicable pages of the service
manual. This enables us to investigate which components could be changed in
order to get the desired level of transmitted audio.

Enjoyable weekend and 73!

Hans Remeeus.
