• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

If I already have a AC/DC inverter for my car would it be ok to use the supplied AC adapter or would I be better suited to get the DC adapter for the car?

A DC-DC adapter would be best (more efficient and much less space required), but I see no reason why a DC-AC inverter wouldn't work.

Most DC-AC inverters generate RFI....DC-DC converters that use a higher input voltage than the output typically use a passive non-switching circuit without components that generate RFI.

Yes my inverter does generate noise, however it's not too bad on the scanner (unless I have the audio output plugged in to the aux input on the stereo).

As far as efficiency with the inverter, you're taking 12v dc, turning it in to 110v ac (modified sine most likely), then in to the transformer where it's going from 110v ac to 6v dc. With the cigarette adapter your going from 12v dc to 6v dc, simple as that.
