Can JBand be Blocked-So it Dose Not Step on SEPTA PD?

[fourthhorseman]

It FRUSTRATES me to no end that when I am monitoring SEPTA PD I'll get PPD JBand
stepping all over their transmissions..

Dose this happen to the SEPTA PD also..

If no,,How do they "lock out" the PPD rebroadcast?
How can I ?

The J band simulcast is in the background on the SEPTA PD channel. SEPTA officers can step on it any time. They are always in the foreground. I'm sure the dispatcher could easily turn off the J band simulcast but I've never seen this done. The only thing I could suggest to you would be to try the ATT function on your scanner and see if that tunes out the J band simulcast.

... I would say "no"... you can not get rid of J band on the SEPTA PD channel with your scanner... ATT will change reception on the uhf septa frequency and that will alter both the J rebroadcast and septa dispatch.

Attenuation would not do anything, both the SEPTA PD traffic and J Band traffic are transmitted at full power over the repeater. They used to have a PL (131.8) on the SEPTA PD portion, and no PL on the J Band portion, so you could just enable the PL on your radio and problem solved. Now that they enabled the PL on both portions, you can't do that.

Agreed,,Seems that JBand will override despite using the ATT feature..last night and today,no luck..

Fingers are allways crossed for them to build a TRS for their PD...they have the freq's...

Always been the total opposite for me. SEPTA PD transmits over the J-Band simulcast.

That's how it is supposed to be. I monitored it last night and as usual, the SEPTA units were transmitting on top of the J band simulcast.

You have it set to open SQ or to the CTCSS?

ctcss 131.8

Humpfh...

I Swear,Ill be listening to SEPTA Disp and an officer going back n forth,,then J will come over and completely crush SEPTAs signal...

Any time I listen, the SEPTA dispatcher/officers take priority. The J Band rebroadcast is on there for the benefit of the SEPTA officers. I have never heard it actually interfere with a transmission. There are times where it sounds chaotic because there may be a SEPTA incident on a concourse somewhere that has a lot of chatter between dispatch and officers and instead a moments of silence in between, there is the constant droning of J Band flashes (related or unrelated to the SEPTA incident) in between SEPTA transmissions. Sometimes, I just need to lock the channel out. Too much chaos. I honestly don't know how the beat officers can make sense of it if they're working in a noisy environment.

after listening for a few days,underground interference that is causing the SEPTA signal to drop and J to come through feeling like the culprit..
Still is a bummer that the two cannot be separated..
