I’m kinda in a marginal 800 signal area at this point so I’m thinking a dummy load wouldn’t receive anything. Am I reading you incorrectly?
Your signal must not be that marginal if simulcast is an issue. Simulcast issues means you are getting a strong enough signal from at least two different sources to cause conflict. It is cheap way to try and fix the problem, a directional antenna is another way. Just throwing some ideas out.
Understood. At my last residence there was a single tower covering the entire corner of the county and I had the same issue. That’s one reason I’m suspicious that I may have a setting wrong
That looks to be the newest update for the 996xt. There is a thread in the Uniden forum from back in 2013/14 indicating that 1.07.03 will be the last firmware update for the model. It seems that Uniden is only updating their current line of radios, and the recent updates were driven by new hardware componentry, and not better performance or new features.
Could you post your Freescan file, although I doubt? Another possibility if you think it is not simulcast distortion is a hardware fault or defective antenna, antenna cable, or antenna connection to the circuit board. What does your display show for RSSI?
Try using the attenuator under the site settings. Some reports it helps and is a simple thing to try and costs nothing.

The OP said he was "near" the transmitting radio. Depending on how near and if a repeater was involved it could be desense from the transmitting radio blocking the scanner receiver.

The transmitting radio was probably a 2W portable transmitting in the 806 MHz range; probably too weak and out of band to be much of an issue of his scanner receiving in the 851 MHz range.
Well, the update is that I'm auditioning tvengr's file and seem to be getting better reception on the 996's. The main diff I see is that he loads the control frequencies only whereas I loaded them all. I think that this system is particular to loading frequencies in a specific order (I did per radio ref's database) but perhaps the list is a touch out of order causing transmission skips. I'm hearing notably fewer garbled transmissions.
The 396 is still in question, it seems that the antenna on that is not longer functional so I had to try with a piece of wire.
QUESTION: Can anyone recommend an SMA antenna for my 396? I use the 800's + VHF high & low.
I'll try to search the forums for this but I usually can't find the info when I actually need it.
It appears that ScannerMaster is out of stock on many of these. Drat.
Thanx all.

The control channel can be found faster if the active cch is the first in the cch list. Loading traffic channels in a Motorola P25 system does not have any advantages, and may result in missed calls during the time the radio looks for the active cch. One scenario *could* be is that your radio was losing the chh, then started to search for an active cch. The radio's logic would advance to the next frequency in the list and sample that for a number of seconds, then move to the next frequency and so on. If you had a list of 8 channels, that could take ~30 seconds to return the the active cch. Some people only program the active cch (again in Motorola SmartZone and P25 systems) which probably would help in your situation *if* the Carroll County system doesn't regularly roll to an alternate.
HRO shows the 800 version in stock:

This developer saved me from buying a SDS to solve the same problem on the Baltimore City system. I use an Airspy, but if you don't want to spend that kind of money two or three RTL-SDR dongles should cover the frequency range of most systems in Maryland. There's a bit of a learning curve, but once you get set up, it runs itself. It also links to the RRDB to make setup easier once you get the system programmed.

that's what I just ordered, thanxI've always had good luck with Remtronix antennas. I use the 800 MHz version since that's what I listen to the most.

This file seems to work better than mine, thanks so much.
Per chance, would you have something similar for Baltimore County? It's prob 2 diff groups one for south and another for north.
Thanx Thanx Thanx
Baltimore County is now a single zone simulcast system, so no more North and South simulcast cells (sites) - they've been combined.
That probably explains much of my receiving difficulties there. Thanx
That said, would anyone have a Balto County freescan file you’re happy with and don’t mind sharing?
