I recently purchased a Uniden BCD436HP and can't get it to connect to Baltimore City PD for the life of me. Has the encryption started? Does anyone have advice on this model uniden and configuration for BC PD?

I just checked. Not encrypted yet. Please export hpe file of your favorites list and I will check the programming.

Thanks for your help. I also have a Howard County hpe centered on Ellicott City zip 21043 that doesn't pick up police either. Both are attached.

The first thing you have to do is update the database and redo the favorites lists. Baltimore County is now a single site. It no longer has north and south sites. You have the frequencies for the old Howard County Motorola Type II system which no longer exists. They are presently using a P25 system.

I cleared data and favorites lists and did a fresh database load and reentered favorites. Howard County Police is working now, still monitoring BC to see if it is fully functioning yet. I think part of the problem was that I installed a firmware and database update, but was still reloading old favorites list.

Right - you have to recreate the Favorites list entries using the new data from the database. The Favorites lists are not automatically updated.

If Howard County PD is working, Law Dispatch is probably enabled in the profile unless nothing was entered in the service type fields in the talkgroups. In that case, the service type defaults to custom 1. You may be suffering from simulcast distortion, especially if you live in Baltimore City. Try backing the squelch down to 2. Try turning on the attenuator. What is your location?

Baltimore City Fire is working. I enabled Law DISPATCH, TAC, and TALK all in "select service types", but whenever I remove monitoring of "full database" so the scanner only scans my favorites, the TAC and TALK both have "--" next to them instead of a "yes" or "no".

I'm located in Ellicott City, about 8 miles from Baltimore City. Range is set to 20 miles. Squelch was set to 2 previously. Not sure how to turn on attenuator, but i'll figure it out and try.

I've set the attenuator to "on" for Baltimore City broadcasts, no luck. I have heard complaints that the BCD436HP regarding simulcast. I've heard the SDS100/200 have implemented I/Q demodulation for QPSK signal. Could this just be a limitation of the BCD436HP?

If you can hear the fire side on the 800 system, then it is not a reception / simulcast issue as both services use the same trunked system. If you are hearing the fire side over VHF (sort of a backup, though unreliable,) then you may be suffering from simulcast issues.

Set your scanner on Hold with the TGID 9002 A2/C2 Dispatch talkgroup for Baltimore City Fire and see if you hear anything. You only need the last 4 frequencies in your list of 27 (24 thru 27) for the Baltimore City trunked system. They are the control channel and alternates. I would delete the others. The scanner won't have to search through all of the voice frequencies to find the control channel. That can take a while. I don.t see any problems with the programming. You most likely have a weak signal or simulcast issues. Ellicott City is in a big hole. Reception of Baltimore City may be difficult with the attenuator off.

I should have said in your list of 28. The first frequency is in position 0. You only need 853.7000, 853.7375, 853.8750, and 853.9500. All of the frequency information is carried on the control channel.

The current cch is 853.8750. No evidence of encryption on the routine police channels, and fire is also normal, monitoring from the UMBC campus.

Ok, a usable signal for the city 800 system drops at around Rolling Road on Frederick Road east of Elliott City.
