Astro Spectra Squelch Tail in Scan

[jmr061]

I have been working on getting scan to work faster/better on some astro spectras. I have the rx rule on all personalities set at zero and rx muting rules are set at standard. When the radio is not in scan all works well. But when I scan, any PL personality except the priority channel gets some amount of squelch tail at the end of the transmission. I have noted it only on repeater channels that are passing PL.

Question: is there something in the programming somewhere that will eliminate this? Jacking up the squlech doesn't help. The squelch tail is VERY noticeable.

Thanks

If it's any consolation, I noticed that my regular UHF Spectra, when scanning through modes with a mix of PL and DPL, there's also a squelch noise burst on the active channel when it stops transmitting. Usually it's a DPL signal that's most active, and even though there's a turn-off burst, the radio seems to ignore it.

As with most Moto radios, the combination of receiver unmuting/muting settings and the priority/non-priority settings affect the operation of the Squelch Tail Eliminator function.

When in scan mode, the RX muting setting reverts to OR no matter what the software setting may be. In the OR mode, the STE still works unless at least one priority channel is set. If a priority is set on at least one channel in the scan list, the control logic disables the STE function, and if the scan resume delay is set to zero, the receiver doesn't even wait for the STE burst to complete before resuming scanning. At least this is what the Moto schools teach and what I remember in the tech manuals regarding STE settings and what I've observed with my own Spectras.
