shorthand response (remember, shorthand messages will not be decoded if multi is on)... or

you just prefer to not be overloaded with many lines of decodes while in QSO. Regardless of

the reason, the single decode mode has many uses. The default of 100 Hz for single band

width should generally suffice. With experience it will become apparent where the other band

width options apply.

AFC enables automatic frequency control and will attempt to follow a signal that exhibits drift.

Its original intent is to compensate for Doppler shift when using JT65 for EME contacts, but it

has application on HF as well. Not for Doppler shift compensation, but for stations who show

VFO drift. Over the years I've found that having AFC on is the default condition for my station.

It certainly helps at times and, as far as I can tell, never hurts.

Noise Blank attempts to limit impulse noise like atmospheric QRN from lightning. Living in

California I can't remember ever using it, but, during my ten months in Florida it was more

often on than off.

Enable Multi-decoder does exactly that. When enabled the decoder will attempt to find and

decode all possible JT65 signals within the 2 KHz pass band.

Log QSO will be covered in the next section.

Restore defaults will clear the message buffers, set TX DF and RX DF to zero and is a quick

way to clean up for doing a different contact or after calling CQ.

Dial QRG KHz is for entering the dial frequency of your radio. Unless you have RB and/or

PSK Reporter enabled it is not strictly necessary to bother setting this.

Enable RB and Enable PSKR will be covered in their own section to follow.

Decode Again will attempt to run the decoder again on the previous minute's data perhaps

with different settings. It will only be enabled when valid data for the previous minute exists

and its running will not interfere with a 'real time' decoder cycle. As such you will see the

button be enabled and disabled at certain times. This is still a relatively new feature in JT65-

HF and still has some bugs as of 1.0.7. As time permits these will be addressed so, for now,

don't expect decode again to always work just right.

Clear Decodes will clear the text output in the decoder section.
