Greetings, again...

One of the responders, to this message, was kind enough to send me a .pdf
file of the icom 22s schematic... again, to him, many thanks..

From this schematic I learned many things about differences between the 22
and 22s...

Now I need the component and conductor drawing of the 22s... I know that
the transmitter is being keyed, when the ptt which is depressed but there is
no audio being transmitted... I also discovered that the +duplex
and -duplex functions are not taking place... the audio turn on and the
duplex function may be originating from the same ptt function...

Does anyone know where I can get the print circuit board layout for the
conductor side and component side for the main circuit board for the icom
22s transceiver??

Greetings again..

I found the problem with the audio output chip, so that problem has been
solved...

Does anyone have a copy of the icom 22s.. this is the diode matrix
version.
the manual I have, ic22, has the crystal board version..

I am looking for someone who has a computer scanner who could scan the
schematic drawing and email it to me. My photo program and scanner can
handle .tif and jpg formats and possibly other but I am only familiar
with
those two..

If you can, would you scan the page and send it to me uncrushed.. I
scanned
a blank, 8.5 by 11 inch page and it took about 120k.. my isp can handle
that...

I now have a good copy of the schematic, will send it to you on request.
