Simi Valley PD Dispatch Switcheroo

[Opfor2]

exactly and my scanner shows ENC on the display. Last night (Friday night) and no Simi action at all is very strange.

Maybe it was just a quiet night. I don't think there's anything sinister going on and they are loud and clear this AM on channel 2.

during encryption a NAC is not transmitted so it wont decode on your scanner if its NAC capable.

That's... completely wrong. NACs are part of P25 at a fundamental level, and encryption only changes the encapsulated data (voice or packet data) and the algorithm ID flag (which, if isn't set to Clear (0x80), the scanner displays ENC and should mute the audio). NACs are present on all P25 signals, and all P25-capable scanners support NACs.

6/20/2020 heard them all day on channel 2

482.4125mhz is very low powered compared to Channel 1 - 453.925mhz.
Barely comes in using outdoor antenna and not with BNC rubber antenna from SFV

I did not scan 482.4125 when I was at the HAT yesterday, just the main one.


btw: Using same outdoor antenna I get Monterey Park and Alhambra with full bars. Simi ch2 barely 1-2 bars from Chatsworth

It’s that damn mountain. I live close to the east side mountain and I can’t get LA for the life of me. I get Simi on a handheld scanner with stick antenna with no issues.

I'll try it on my attic mounted discone and see if I can hear it from Winnetka. Thanks.

I tried listening to 482.4125 for an hour today on my attic mounted discone. Nothing from Winnetka (Western SFV)

Location, location, location. Loud & clear here in eastern Ventura with 996XT & roof discone. Also my handheld (396T) with extendable at my desk. Dispatch encrypted for last hour.
Not much traffic tonight.

 

[Engine104]

Must be the Simi Hills in the way, then. Oh well.....

 

[Paco-Jerte]

Just tuned to 482.4125 about 5m ago and heard a few back to back transmission ENCRYPTED.




SVPD not fun any more

In last 8 min 4 disp/unit exchanges: disp encrypted, unit clear. Unit initiated exchanges.

 

[iscanvnc2]

Now disp in clear.

It sounded like they switched to Tac 2 around the time of the large protest on June 6. Tac 2 seemed to be protest traffic all day. I heard CHP, VCFD and VCSO on Tac 2 all day. I don't know if it's related or not. Units have been using encryption more too.

 

[Paco-Jerte]

453.3500 used today alot too. Plenty of signal on that one using BNC rubber antenna
but mostly ENC

 

[Opfor2]

Woke up this A/M 6-27-2020 and finding that dispatch is encrypted but most of the field units are in the clear.

 

[Paco-Jerte]

482.4125 both dispatch / units ITC

 

[Opfor2]

Yes, they are in the clear now.

At 10:15 pm my scanner stopped on SVPD CH 1 453.925 during a motorcycle pursuit. Normal dispatch followed.

That's right! CH 1 is back. When it came back I have no idea.
