BCD325P2/BCD996P2: missing the first part of the radio transmission

[Wildbillx8]

when opperating an analog scanner against the bcd996p2 scanner.....the 996p2 misses the first part of the radio transmission or pager tone. can someone explain why this happens and how to correct this? thank you everyone for the help...it is greatly appreciated.

The Uniden PL/DPL decoder is quite slow, meaning that it sometimes take a quarter of a second for squelch to open up after a tone is detected. This is especially noticeable if you scan conventional channels, all with PL/DPL enabled, with priority enabled. When the scanner samples the priority channel, then reverts back to an active channel, there is a noticeable delay in squelch opening back up, resulting in someone clipped transmissions. As soon as you clear all of the PL/DPL tones from the channels, audio improves greatly.

So the bottom line is that if you have PL/DPL enabled on the channels you're listening to, especially if you're scanning them with priority enabled, you're going to experience this issue. Nothing you can do about it except to remove all of the PL/DPL tones from those channels, which may not be ideal if you have a lot of users sharing frequencies with different PL/DPL tones in the area.

There is also the distinct possibility that the 996p2 is looking somwhere else when the transmission starts, if you have a huge scan list running and you aren't using priority scan (which as @GTR8000 mentioned samples the priority channel), you will have to wait for a long time until it happens across the active frequency.

How many channels are you scanning on the analog scanner? How many on the 996p2?

Also if the 996p2 is scanning digital channels there is longer delay as it takes more time to tell if a channel has activity on it before moving to the next channel.

If you are using a so called green amplified external speaker on the BCD996P2, it takes a while for the amplifier to turn on at the start of a transmission and clips the audio. I modified the speakers in my vehicle so that they are turned on all of the time. They would completely miss the key beeps when pressing buttons.

Avoid using "All" for audio type and "Search" for tone.

Avoid using "All" for audio type and "Search" for tone.

Setting the tone to Search is fine as long as the audio type is selected, that's what causes a delay in decoding. Read my original post, setting the tone to Search can actually speed things up since the PL/DPL decoder is no longer a factor.

19 channels on the analog scanner and 64 channels on the 996p2 scanner

19 channels on the analog scanner and 64 channels on the 996p2 scanner

Yeah, that'll explain the difference. Compare apples to apples by only scanning the same 19 channels with the 996P2 and see if your situation improves. It takes time to get through 64 channels, you can't expect it to perform the same as a scanner that only has to get through 19 channels.

whats the analog model #?
