PSP freq question

[nvycat14]

Occasionally my scanner stops on a PSP frequency, and what stops it sounds like morse code. That's the only way I can think to describe it.

Can anyone tell me what that is and/or why they do that?

Let me guess, you're listening to 155.475MHz (Nationwide Law Enforcement)? I hear it all of the time on that frequency.

I _believe_ that the morse code you are hearing is the FCC ID of the frequency, but I'm not positive.

Yes, that is FCC identification. I hear it on 155.5800 here in central PA. Not all barracks do it, but there's one somewhere in the area that does.

Does anyone know why in the Harrisburg area I am unable to hear the troopers in the field. I can hear dispatch loud and clear. I am about 30 miles from Carlisle but I can hear dispatch and the troopers in the field on 154.665 loud and clear. Just curious if anyone knows the difference. Thanks for any help.

I am not from that area, but I think you have an error. There is no PSP freq 154.665. Maybe you mean 154.755. That's mobile to mobile, but the base stations use it from time to time as well. For the area, these are the freqs'
Base ..............Mobile
155.58000 154.95000 Gettysburg Channel A
155.67000 155.91000 Harrisburg Channel B
155.44500 B&M Carlisle Channel G
You probably know all this, but your "error" above made me think this could be of some help. If not, then maybe you can verify to you are listening so others may better help.

PSP does use 154.665 C/S KSO727 (Dauphin County,PA)


Type in that call sign in the FCC database for additional related freq's.

Yikes! Of course it does:Channel D. I can't believe I missed that. I WAS looking at troop H, which is the general area of the msg, but still
Because KSO727 just shows the base freq's, the mobiles for that area are on 158.910

Hello, Assuming you are in SE PA,

The CWID is from Berks County's 155.475 transmitter. Sometimes you can hear Reading's TRS patched into this also when a joint op is taking place.

PSP Carlisle Barracks is one of the few areas where the system operates as a repeater (the others being Hamburg/Reading on Ch E and Hollidaysburg on Ch E).
Every other station (except those on OpenSky) operates half duplex so you need to monitor both the base and mobile side. For PSP Harrisburg, this would be Channel B (155.670 Base / 155.910 Mobiles).

Media barracks has been ultra-quiet for the past few months.

I manage to get a few comms on the Blue Route (476) once in awhile.

The BUMS!!!

What is the advantage to PSP using a different freq for base & for mobile? It would seem that either establishing repeaters with one freq for input & one for output....or just using the given pairs of freqs as 2 different simplex channels might be a better use.

Yes, that is FCC identification. I hear it on 155.5800 here in central PA. Not all barracks do it, but there's one somewhere in the area that does.

Yes, PSP-Lamar (Troop F) uses the morse code for there FCC callsign.

What is "FCC identification" exactly? I tried Google, but to my not-so-technical eyes, I didn't find anything relevant.

I'm also not sure which freq it is. I think it does it on more than one, actually, but I'm not always right beside my scanner when it starts.

Thanks for the help.

The FCC requires radio license holders to broadcast their assigned callsigns (issued by the FCC) at certain times. Since the broadcast does not have to be voice, some public safety entities (and others) do this with an automatic morse code burst that transmits the callsign throughout the day.

So this actually is morse code? I thought it was just random beeping.
