BCD536HP -NAC settings?

[XPS720]

My SDS200 under settings has a NAC yes/no. Does my BCD536HP have NAC?

Thank you,

No NAC on 536.

No NAC on 536.

My BCD436HP has NACs. Why doesn't the 536 have them?

NAC setting was introduced in the SDS series.

Okay, so if the Network Access Codes in scanners didn't come out until the SDSx00 then why does my BCD436HP have them?

Conventional yes, trunking no. So if the SDS has it, but the 536 doesn't, that's the setting he's looking at.

So the link you provided says that the Uniden Bearcat BCD536HP has the NAC feature. But @wearinshades says it doesn't.

Oh you meant just trunked systems. I didn't think trunked systems needed an NAC since the computer controls it all.

Go into your Sentinel, click the Site tab, and let me know where it asks you "Use NAC Code yes/no" under the 436 profile. That's the setting he's asking about.

In the event two trunking systems are in range of each other, and use the same frequency or frequencies but different NAC's, that's where the setting is beneficial.

I see what you're saying now. I thought you were just talking about conventional P25 frequencies.

That makes sense.

 

[werinshades]

That makes sense.

Sorry for the confusion, I should have been more specific and typed "NAC Trunking was introduced on the SDS series". But I knew what the OP was looking at and directed towards the question.

That's okay. 👍

And then it would be just as beneficial to the 536, but Uniden haven't added that 5 lines of code to the x36 series, making Sentinel and the scanners programming identical to the SDS series for trunked NAC codes.

The SDS series needs all the help it can get to sort out RF problems that the x36 series do not have. The SDS's poor selectivity and receiving of mirror frequencies made it necessary to add the filter settings and the additional NAC for trunked systems, that could just as easily have been added to 436/536 but haven't been done as it isn't needed there.

Oh boy...here you go again... I don't know the reasons, but if two systems are using identical frequencies and are both in range, the SDS series will have the upper hand as the x36hp series doesn't have the capabilities and will probably have a problem with decoding the system. Then again, the x36hp blows chunks when it comes to simulcast unless you have the perfect location/perfect beam antenna/pointing at the perfect point of the antenna/ when the wind isn't blowing from the wrong direction, and....and.....you bend the paper clip just a tad more. So there.... Plus...you certainly have alot of issues with a scanner you still don't own so pipe down over there.

Great response to my question and I did learn a lot.

Thanks All

Apparently @Ubbe has access to the source code and can fix bugs in 5 easy steps. Impressive.
