[NLRS] CW Operation question

[Dr. Gerald N. Johnson, electrical engineer]

If you need to retune up 700 Hz when going from SSB to CW, it sounds
like you have a Yaesu 726 or 736. I have both, but I find that annoying.
Generally when I call CQ, I dial up 700 or 800 Hz above the calling
frequency. That way the CW signal is sure to be in the SSB receiver
tuned to the calling frequency, and likely to be in the CW receiver
tuned to the calling frequency or 800 Hz above it pass band unless the
CW receiver is using a narrow filter.

On a scheduled band change, most will tune about a bit if they don't
hear a signals because the frequency display resolution is as much as a
couple KHz more precise than the accuracy of the true frequency. E.g.
especially at 432, the radio can be on a frequency as much as a couple
KHz from the true frequency. As the result most of us disagree a KHz or
two about what IS the frequency.

I've learned to not grumble about the differences, though I can set
frequency to a few parts per billion, the radio doesn't hold it between
calibrations. So I tune a bit as do others.

When on CW mode and you are about to answer a CW CQ (or tail end a QSO)
you set the tone of the received signal to 700 or 800 Hz and then you
are about Zero beat with their signal. Most radios make the sidetone
about that same pitch so you can match that to be closer.

These techniques work, if I can only remember which way the &*&%$# radio
moves when I make one or the other mode switch or if the other signal
stays there long enough for me to complete the mode switch and the
frequency correction. Future radios won't bother me that way. I may have
to build them from scratch or use a transverter with my Tentec Corsair
II.
