PX3 makes tuning in a PSK31 signal more accurately

Well one of the things I have found that the PX3 helps with is being
able to more accurately and quickly to tune in a PSK31 signal verse
using the CWT Tuning Aid. I set the PX3 span to 2 or 3KHz and tune the
VFO so that the PX3's cursor's bold line is on one of the 2 PSK signal
peaks. If you put the bold line in the center of the signal then it does
not decode. I have also noticed that tuning to the left peak seems to
decode better than the right.

BTW, I have started posting to this reflector as the KX3 Yahoo reflector
seems to have issues with messages being posted, I have noticed it takes
a long time to post and when it does I have noticed my messages have
been altered.

Re: PX3 makes tuning in a PSK31 signal more accurately

The method you just described has been exactly my experience. Using the PX3
I tune to the left peak, and it decodes well every time. Tuning to the
center does not work. CWT has never worked well for me.

Re: PX3 makes tuning in a PSK31 signal more accurately

My 2 cents on CWT tuning: I find it usually takes two times to get it to
decode reliably: first time gets close, then pressing CWT a second time a
second later gets it right. Works best if no other PSK signal is around,
otherwise it gets confused...

As Ed also noted the CWT sort of works, sometimes, but using the PX3 it
is always right the first time when using the built in decoder.
