Philly 800mhz System Status

[phillydjdan]

BTW, just wanted to let folks know I managed to adjust the alignment pots inside my Pro-96 and I got it working on the new system.

[mikedel83]

Dan, what did you do to adjust the levels? There is a screw on the logic board that I believe is red or orange, is this the one you turned to adjust and align the levels?

[phillydjdan]

No, not the big red one, refer to my post in the other thread

Anyone else notice some of the "sensitive" channels are half in the clear? From time to time I get a "wild card" hit from one of the encrypted channels but only one side of the conversation is scrambled, can't they tell they're not completely encrypted?

They'll know now.

I hear this happen on other supposed encrypted channels, not just on this system. Seems as though the radios are set up as to make the secure mode switchable on/off via a programmable button as opposed to programming the channel as secure only. They must have their reasons for doing this. My guess is that not all radios in the group are secure equiped....yet.

But how does a non secure equipped radio decipher the ones that are, this is what I'm saying, two people having a conversation, one clear, one not.

I hear what your saying,,User 1 is say...a spotter...calling out targets in the clear,User 2 is say...a scoop up team..responding in the full ENC mode..

its simple,the radio will receive and decrypt the signal,being on the same TG the radio dose not care if the transmission is encrypted.either way the user will hear the others TX..as long as the (encryption) keys make the proper -Handshake- its all G2G...the PPD TRS dose not use any OTAR systems,so i believe the keys are set and left...

Fed systems sometimes have the issue of radios not being loaded with the matching Enc-key..you will,,on occasion hear a user say,,switch to clear,i cant understand you.. or
something to that effect...(been a while since i monitored FEDs)..

this is due to 1 radio being updated via OTAR and the 2nd Not being updated...again,,the ctiy dose not seem to use this set up..Yet

Philadelphia (Project 25) Trunking System, Philadelphia, Pennsylvania - Scanner Frequencies

The above page points to the current Philly system. My understanding of the system is zone one is fire and most city services. Zone 2 is mainly police.

Recent wildcard hits TalkGroup 1303 and 1305. It is very active. It sounds like it's the Philadelphia Parking Authority. Can anyone verify?

[fourthhorseman]

PPA..tomorrow (philly's marathon sunday)
would be a good opportunity to verify,they
may be doing car relocation for the race -
especially after the boston marathon..

Loading those TGs now to see who uses them..

Thanks for the update!

PPA Conventional Channels are silent now. It appears they have TGs 1303 and 1305 - I can confirm 1305 sounds like PPA Channel 3 (Tow Squad). Also last night picked up a wildcard hit on TG 1803 - sounded like a radio check but couldn't identify what it was.
