BCD436HP/BCD536HP: Bcd536hp problem after update

[n4anz]

I have a Uniden BCD536HP scanner. I performed an update on the scanner last week, and since the update I have no longer been able to hear Vanderbilt LifeFlight. I was receiving Vanderbilt LifeFlight normally before the update, but I have not heard any of their transmissions since updating the scanner. I would like to know if something changed with the system, frequencies, talkgroups, or database information that could be causing this issue. Not sure what has happened Any help would be greatly appreciated

Hi. Have you tried pushing your config to it again?

Hi. Have you tried pushing your config to it again?

If I also forgot to mention that I have this configuration programmed into the sds200 also and I'm not hearing it on that scanner either when I was hearing it on both of them

Zip up and post your Sentinel .hpe export so we can have a looksee on your programming. Did the SDS200 undergo an update too or did it randomly fall silent untouched? When you say "update" are you referring to firmware or programming?

I am not around the Sentinel softwares this time but I can do that later this afternoon for your question about the SDS 200 I also did an update on it

Vandy has moved to the TACN Trunking System 100% they no longer use their old radio system.
Uses talkgroups 48250 and 50992. Conventional appears to no longer be in use (6/26)
This also has been discussed here in outer threads

Vanderbilt Lifeflight 4 CC

Does anyone know the control channels for Vanderbilt Lifeflight 4 Mt Pleasant TN

The TACN trucking system is what I was receiving to them on. once I did the update I no longer hear them on the 536 HP or the sds200

Are you using Zip Code to scan with? Do you have a Favorite List setup? There was a massive update to the TACN system on Aug. 15, 2026.

 

[n4anz]

I am not using zip code to scan I do have a favorites list

 

[Enforcer52]

I am not using zip code to scan I do have a favorites list

Once you updated the database then did you update the favorite list? Because favorite list doesn't automatically update when you update database.

My 536's SDS200's SDS100's SDS150 996P2's and 325's all were working yesterday.
Are you hearing other TACN Traffic?

Yes

I seen thp on the display yesterday afternoon but I never heard any audio

In the meantime please confirm the EMS Dispatch service type is turned on and the talkgroup(s) aren't avoided

 

[n4anz]

Service types are all turned on and nothing is avoided

You are scanning 139 towers across TN and GA and who knows elsewhere, with 821 frequencies which include ALL frequencies on those towers. The majority of which are out of your range!

Do you realize just how long it takes to scan thru this list just ONCE!

Edit: There are only three TACN towers within 25-30 miles of Hampshire, and only one showing in Maury county. I would think you would need a good outside antenna, in your terrain, to reach any of them.

You need to cut it back to just the towers in your immediate area to start with. Just my first impression and opinion.......

As Enforcer has noted, you have way too many sites in your list. You probably created that list by appending the system via Sentinel. During the append, you can carefully select only the departments you want, and append only them. But Sentinel will still append every site in a trunked system. No way around that.

You can either go through and delete the distant sites, or set them as Avoid (locked out). But, you can effectively trim down the excess by using location control. Set your list to use Location Control, and set your location, as well as a reasonable range, in your profile in Sentinel, then send the list to the scanner.

 

[Enforcer52]

Here is what your Favorite List should look like with Maury County TACN and all the TACN counties that surround Maury. Only the control channels are included, which is all you really need. I included the TGIDs that you had programmed in.

Towers reduced from 139 to 10, Frequencies from 821 to 18. So scanning will be much faster.

Download the MauryTACN file, unzip and use Sentinel to import the .hpe file. Then write to the scanner.

And then go and buy a copy of ProScan, much better programming software than Sentinel, and does tons more!
