Sussex Co./VSP/Prisons 700 mhz. Interop

[reconrider8]

Going to throw this out there but has anyone got op25 to work? What about on this system? I don't have a phase 2 scanner but I do have vmware and multiple versions of Linux

Op25

Op25?

 

[reconrider8]

its a linux based sdr receiver to decode p25 transmissions

1109
1090 734xxxx
1111
1080 733xxxx
1107
1119
1047- Sussex
1107- 769xxxx
1119- 769xxxx

I’m thinking that 733xxxx & 734xxxx are Sussex 1&2 and 769xxxx is Greensville

 

[vern23882]

That is correct.

That's interesting. I don't listen to them that often as it is distracting to me if I'm also scanning another trs on the 536. I have noticed that 1090 and 1119 appear to be the stronger TGs of what I do receive. I would have thought that Sussex I/II TGs would be the stronger than Greensville since I am NNW of Sussex I/II, but TG 1119 (Greensville) equally is as strong as 1109 which is good.

Now when you say stronger do you mean signal wise or activity wise. I would think the Sussex 1 & 2 would be more active being that they are maximum security

As long as it's noise free 24/7 I'm happy.

------------------
There are a number of factors which impact a signal from Site A transmitting to you at Site B. There also are what is should be on paper also should be the same when operational but sometimes is not the case. For example, I'm assuming the antenna configuration is equally 360 degrees omni-directional. I am assuming the repeater power inputs are balanced and 50% efficient. The 200 watt input should be approximately 100 watt ERP output plus the antenna's gain which increases the actual ERP to whatever.

I noticed that with no comm activity the 536 signal is 5 bars cycling on the 536. However, tg 1107 just had a short comm at 2 bars strength with audio. The audio was noise free and readable but not as a strong a signal that was physically sourced closer to my location where it would be stronger input to my 536. The previously posted two talkgroups I mentioned being stronger resulted a slightly increased ERP signal compared to the other talkgroups. .

I had similar reception when Sussex I/II trs was analog on 800 mhz. Those signals were noise free and readable but did not have impressive strong signal strengths.

Actually, as long as I can hear whatever to hear is noise free, I'm happy. The biggest problem I have is sometimes trying to understand the words being said with loud background noise on occasion present which almost is as the speaker who sometimes slurred his/her words. Taken as a whole, it has a cumulative negative impact for me monitoring this trs sometimes.

Why no UID for every TG voice comm?

I've noticed on the various talkgroups I hear that rarely does a UID display. Most of the TG comms which appear to be HTs to various particular controllers display no UID. I thought all radios especially in this controlled environment would have a UID???

any updates on this system?

 

[vern23882]

What would you like to know? I have some information.

i finally have op25 running last time i was up near SSR i tried to monitor with regular p25 scanner but was thinking of maybe trying op25 up there soon and seeing what i could monitor if i could monitor
