Locked JT65B "Sync Threshold"


Christian BARTHOD F8GHE
 

Hi Team,

The JT65B "Sync Threshold" parameter (from -1 to 10 on the main screen) is not very clear for me.

The user guide speaks about it but I don't understand : "The Sync control sets a minimum threshold for establishing time and frequency synchronization with a received signal."

Who can help me ?

Hi Christian!

Think of it like the "SQUELCH" on an FM handheld. -1 setting turns the "SQUELCH" OFF. As you increase the Sync Threshold, stronger signals are required before there is any decoding. GL and VY 73, Lance

Hi Lance,

OK now  I understand but is there a recommended default value between -1 and 10 to start or is there a specific method to control (check) the right level of this parameter during the decode processus ?

Hi Christian,

For EME, we always start with the most sensitive value of -1. GL and VY 73, Lance
