Harry: All transceivers sold today, when in the cw mode, use a transmit
frequency that is offset from the receive frequency. The amount is not standard
but the average is approximately 750hz; give or take about 250 hz. Therefore,
the proper way to tune your transceiver to answer another stations cq
is to tune carefully until the tone of the received signal you are listening to
exactly matches the transmit offset of your transceiver. As an example, if
your transceiver has a transmit offset of 750 hz., you should tune your
receiver so the
tone of the signal you are listening to is exactly 750 hz. That way,
when you answer his cq, your transmitted signal will be exactly on his
transmitted frequency. (Several years ago, QST Magazine had a good explanation
of the
proper process to tune in a cw signal.) If you tune until his signal sounds
like
500 hz., you wil be 250 hz. off of his transmit frequency. If you zero beat
the
signal of the station you are listening to, your transmitted signal will be 750
hz.
off of his transmitted signal! Because most manufacturers do a very poor job
of explaining this in their instruction manuals, most ham's, including me, find
all this
very confusing and difficult to explain.

Hello,
think my cw offset adjustment doesn t.
Hooked up a second receiver and set the offset to 400 Hz and
listen on the second rx, then set the offset 990Hz and listen again,
the signal was still present on the same qrg on the second rx.
I thought the signal should be 590 HZ up or down now, but is still
on the same frequency on the second rx.
