Richard,
Good sugestion...I'll check it out now.
Also, just a second thought on the speaker impedance...based on my
experience in Audio as well as Ham...one should match the impedance of
the speaker to the impedance designed into the audio output circuit,
mostly.

Subject: [Drakelist] My R-4B audio?
I have a R-4B here that I'm thinking is still low on audio
output??
For those that have one too....where is the 'normal'
setting of the AF
gain for you....
For a pretty loud level, not super loud just a nice loud
level you
could here fine on loud signals of S9 or so .
What setting on yours would you consider super loud and
want to turn it
down?
Seems like I have to use around 1:00 on the AF gain to get
decent
loudness.
I'm just trying to find out if my audio is pretty normal??
Thanks,
73,
Lee
Another afterthought. The speaker jack in the back is
connected through a contact on the headphone jack on the
side of the RX. If the switch gets flakey it can cause the
audio level to drop. Work the jack with a plug a few times
to see if it helps. Also, the jack is connected right across
the output transformer so you can plug a speaker into it. If
its louder that way its an indication that the jack switch
or perhaps wiring or the RCA jack on the back has a problem.
