Hi,

Weird, as I'm using it everyday on a MD-UV380.
To mark a channel as nuisance, you have to:
1) wait scan stops on that channel,
2) press "*" key.

There are some limits:
- 16 nuisance channels max,
- at least 2 channels has to remain to the scanned zone, otherwise scan stops (pointless to scan 1 channel only).
- nuisance is temporary, once you stop scanning, the nuisance list is cleared.


Side note, you forgot to introduce yourself here.

Cheers.

One further point to note,

When doing a VFO scan the exact nuisance frequency will be skipped but the scan may still stop on adjacent frequencies, especially if the step size is left at its default 2.5Khz. Ideally you should change the step size to be the same as the expected channel spacing (12.5 or 25 Khz), or alternatively you may have to press * several times to skip frequencies either side of the correct one.

Set the zone skip to these channels, this way they will be ignored while scanning (in channel mode, not VFO, of course).

unfortunately in VFO is where I need this skip the most, since this way I can listen to trunked analog. however have to skip plenty of control channels which this radio obviously cannot decode. in any case, since 16 nuisance channels is a limitation, not a bug, I guess we can close this one.
This firmware is designed for Ham radio use, and not primarily to make the radio into a scanner.

You would be better off buying a radio designed to be a scanner.

I don't understand you, why would you scan as vfo in a first place? VFO scan is an old way to find traffic and very hard way - you are playing cat'n mouse.
If you want to scan through frequencies with opengd77, make them as channels. How to find frequencies? Buy rtl/sdr usb, install sdr#, find frequencies with traffic that you want, open opengd77 cps, make new zone for example name it scan; put channels into the zone, flash into the station, scan through frequencies.

Hi,

Why not creating a zone with the repeaters list (VHF, Rxx and UHF, RUxx), they (must) follow the standard's repeater channels.


Cheers.
