SSB Drive

[KR4OW]

Hello all I have K2 4320 with ssb module
I have noticed that I do not get any real drive out of
what ever mike that I have used. it is presently wired
Yaesu for a mh 36 mike. But I also have a md1 yaesu
mike that will also work on it. but it too does not
seem to have enough drive.
with the mike and compression seeting to max I can get
1 alc bar and that is it. also I get reports that My
audio is flat Not bad but flat. I have gone in per the
manual to try and taylor the audio but with no avail
it does not do anything for the drive.
So I put the settings back to where they were. Is it
possible the alc is holding back the drive?
Any suggestions or mods I can do for this?? it is the
2.3 rev. July 2004
Thanks
KR4OW

Hi David,

It is my experience that to use Yaesu mics with the K2 you really need a pre
amplifier, either internal or external. I have an internal one built on a small
piece of perforated board, and mounted on the mic jumper block.
It gives me enough gain for my MD-100 desk mic, and MD-31 hand mic.

The flat audio is probably because of the excessive low frequency response in
the KSB2. It can be cured by reducing the values of the coupling capacitors.

I you look on my site,  you will see details about how to cure both problems.
