Negative Delay setting for search will solve that.
Yes there is. Program the tone or DCS code for a conventional channel, and it will not hang on digital. Program the frequency as part of a digital trunked system, and any analog transmissions on that frequency will be ignored while scanning that system.
Negative delay does not solve it, it just continues after a set delay time, not a delay time with no audio, negative delay is the "botch" answer as you well know.
Not all analogue systems use a tone or DCS and that doesn't help in any way when searching.
Its a basic feature that's missing, the TRX scanners don't suffer with this, the AOR DV1 doesn't, my MD380 doesn't, my Moto SL4000 TRBO radio doesn't, my CS580 doesn't, its only Uniden that have missed this important option out and are continuing to do so.
The trouble with Uniden is they are still trying to use the old fashioned way of detecting the carrier ratther than the digital content, I was hoping ths SDS was a move forward but I'm not so sure, it feels more and more like a re-packaged 436 with *maybe* the final few kHz digitised so it can be called an SDR.
