There is an error in the BC-230 circuit diagram that appears
on my site zl1anm.com. The diagram is labelled:

"Circuit diagram showing modification, fullsize in new window"

The DC feed to the microphone from the filament supply is
shown connected to a junction of resistor 101 and terminal 1
of the mic transformer. The junction does not in fact, exist.
The feed is simply to the top end of the resistor and there is
no connection to terminal 1, which connects only to terminal
33 of the PL-64 socket.

The dot that currently shows a connection will be removed
and the correct version will be uploaded as soon as possible.
The error has no effect on the mod but I'm concerned that,
because the diagram is large and clear, some readers may
be referring to it when modifying their transmitters.
