BCD325P2/BCD996P2: Scanner is skipping transmissions...

[RudeMule]

So i have had the P2 for about a week. I have mostly conventional systems programmed and I have been doing a side-by-side comparison with an old desktop BC340CRS. The 340 is picking up the transmissions from the beginning and the P2 is about 2-3 seconds late to the game. This doesnt seem to happen every time but about 50%.

Squelch is set at 2 on the P2 and set about 12 o'clock on the 340
Antennas are the same and the P2 picks up the WX channels much better/clearer.

This has to be a setting that I have overlooked correct?

does it show ATT on the screen ?

Are you scanning the same number of channels/systems on both?

It could be the digital delay if these are analog transmissions. It will wait (typically 0.4 seconds) to make sure the transmission is not digital. To solve that program those channels as analog only.

Before a proper comparison is made you need to consider what Joe Bearcat has stated. Both scanners must be programmed alike. And to further refine the comparison, again, as Joe Bearcat has stated, keep it simple... use only all conventional (non-trunking) choices. You could also compare just trunked agencies in the same manner, just use the same agencies in both scanners. Let us know what your results are.

it does not show ATT

they are not programmed with the same channels but I can make that happen.
I will have to double check but I think I have all the analog channels set appropriately in FreeScan.

I will make some adjustments and report back if I discover anything.

thanks for all the suggestions

if you are trying to see which scanner is missing transmissions both scanners wiil need to be programmed the same way 100 percent and connected to the same antenna at the same time.

So I removed the Project 25/Phase I systems from the 996P2, and tested it with the exact same conventional frequencies as the BC340CRS and it functioned exactly the same.

It appears that including the digital systems in the 996P2 is causing my issue

i will guess you mean trunking systems.
the radio spends 2 seconds on every trunking system for 'housekeeping'.
so if you have 1 system it will be on that one for 2 seconds
if you have 2 systems it will take 4 seconds and so on.
even if you set the hold time to 0, it takes the 2 seconds.

P25 control channels broadcast a repeating loop of data that indicates active calls and other stuff. The loop repeats every 1-2 seconds, and the scanner needs a complete loop to know what calls are active. So there's no way to make that part faster.

Mr Mule that is why I run as many scanners as I do over 20 active Unidens each one scanning different counties and or systems.
Run your digital systems on 1 scanner and your analog on a different scanner you will hear more traffic.
