A common question that comes up is what is the AR-DV1 scan speed? A digital scanner is always going to be slower than a conventional scanner but the settings you choose can make quite a difference. We quite often like to search for new DMR systems only and here is an example of how to do it.
- First we do a search in FM Mode with 6kHz IF bandwidth set and lock out any analogue or data signals which I know I don’t want to listen to.
- Then set the mode to DMR, set the squelch type to level, the actual squelch level you set will depend on what strength of signals you are receiving.
- With the step step set at 12.5kHz it will search about 40 steps per second.
The reason we like to fix the mode to DMR on the AR-DV1 is because it won’t let you select the 6kHz bandwidth IF filter when in auto mode, it only allows 15kHz which is poor for weak DMR signals, its quite frustrating that AOR doesn’t allow selection of the filter, 15kHz is too wide if you only want to scan for narrow band signals.
For scanning memory channels we also find the level squelch the best option.
