Issue with scan in mixed Analogue/digital Zone

Post by IU4LEG » Wed Dec 25, 2019 8:53 am

Good morning and Merry Christmas everyone.
I noticed that during scanning inside a mixed zone of analog / digital channels (eg favorite channels) if there is a qso on an analog channel, the radio does not stop on that channel, while if it finds a qso on a digital channel the radio stops on that frequency.
I think it's due to the speed the scan is so fast that it doesn't have time to switch from digital to analog mode.

Best regards. IU4LEG

OK.

I that's strange. It initially uses the analogue sampling even on Digital channels when scanning

the squelch is set to 25% in the general settings of the 3 bands, vhf, 200, uhf and just above the noise threshold on the single channel.
if I manually set the analog channel where the qso is present I receive it without problems. in scan mode in a zone where only analogue channels are set, the radio stops where it found a qso. in the zone where I set mixed channels, analog / digital, it only stops on digital channels.

hmm, very strange, has this happened with previous versions of firmware?

Have you checked that the zone skip and all skip flags are not set on the channel?

Does the analogue channel use CTCSS on Receive?

Yes, the zone skip and the all skip is set to off for every analog channel. Rx CTCSS is not set.

I have today tried to reproduce this issue without success.
I created a zone with alternating digital and analogue channels which is probably the toughest test.
The radio always stopped first time on both types of channels.

If you can post your codeplug and tell me which zone and channel you are having problems with I will test some more.
