Do the bcd and sds share the same favorite list for scanning?

Make sure the sds has the squelch on "2" that's the number I've found to work good.

You'll have to be more specific about which system for anyone to help you.

Magnetic mount antennas for automobiles seem to be dying off. Many trunk lids and other components are now made of aluminum and a mag mount won't work in such an application.

If you are missing responses on Maricopa P-25, RWC, or Topaz; you probably want to create a Favorites list with just MCSO as part of it and exclude the Animal Control, Constables, Courts, Probation [adult & juvenile], MCDOT, and all the other stuff that can clog your listening. Same with RWC, SRIC, and Topaz. This will concentrate the time spent on interesting channels and increase the chances of picking up the other half of the traffic. Lengthening the delay time can work too,

If you are listening to RWC and Maricopa P25, shorten the factory telescoping antenna to 9.7 inches [5/8 wavelength of 760 MHz]. If you are interested in Topaz, their frequencies are ~850 MHz, so for 5/8 wavelength, shorten the antenna length to ~8.7 inches.

This will get you the best reception for those groups.

You can see in the video that the signal strenght from the site jumps from full bars to no bars. A typical case where you probably have to play with different filter settings and also IFX could be tried on the voice channels. You have some interference that desense the SDS200 so it looses the signal completly. Getting a better antenna could probably make the situation worse.

Try each filter setting for that site from Normal all the way to Off. If that doesn't help then set IFX to the voice channels and try all filters once more. Easiest way to change IFX are to check up what frequencies that are voice channels and then use Sentinel and Edit Profile and go to Miscellaneous and enter the frequencies in the IFX Review and Edit box.

This is what I’m using on my SDS200. It’s the small mag mount with a standard 700/800 antenna. I shortened the coax from the 17ft to a foot. This cuts way down on the loss.CE47EF0F-4469-4C7A-ADEC-F2EAD727FE24.jpeg

Whatre you trying to listen to in regards to salt river? Pd dispatch is encrypted.
another member asked me to list what systems and site to better understand what was going on with my sds 200. so i just thru salt river in general. but yes i seen that they are encrypted.
