Monitoring THP

[ropin4gold]

I have not had very good luck hearing both sides of the conversations on my scanner. Would it work better to have a low band radio programmed to monitor, and if so what kind of setup would you recommend.

I have the same problem. I have programmed the other frequencies listed on the forum, with the exception of the ones in the 74.000 range. My scanner doesn't cover those frequencies. So I'm in the same boat. Anyone knowledgable have an answer?

Also, can the Pro95 be made to receive frequencies in the 70.000 range?

Thanks

Acording to the FCC the Marshall county relay is 452.4500 this should allow you to hear the THP cars calling back to the post and you can monitor the post as you currently do on 42.4200. The other relays are Hickman co 452.2750 and Wayne co 452.2500 you may also try the mobile TX frequency of 42.2600 and the mobile extenders on 154.9050. Here in the Knoxville district when there is a pursuit they switch to one of the low band repeater they are 45.5800, 45.6200, 45.6600, and 45.7000.

Thanks for the info. I have 42.42 and the other low bands programmed. I'll put these others in and see what I get then.

Thanks standby 106 I will try that.

I have a Pro-95 and with Don Starr's program 'Win95' (not windows 95)
you can program the pro-95 to recive the 70 mhz freqs.
I have them programmed into mine and the replies are now heard.
The only thing about it is that the receiver was not made to receive
the 70 mhz band so the reception is pretty weak, but i can now listen
to both sides hear in East Tennessee.
I wish they used UHF freqs like they do in other parts of the state.
Anyway, hope I helped you out a little...
Take care,

Thanks n4yek! I have already downloaded the software (win95) and as soon as I find a RS that has the cable in stock I'll be ready to go. Going to another RS today and hope they have it. If not I guess I'll order it on line and have it shipped to me.

btw, nice web site, really liked the "things that make you hummmm... " link. :lol:

WileE,

I bet you pick up that Short Mt repeater 5 by 5!!!

Or maybe it goes right over your head if you are that close & down in a valley. :roll:

Does anyone know what the A2 and A7 repeaters are used for?

Ten miles as the crow flies. I can see both towers out my window as I type. Which one is it? The one with white lights or red lights.

Well, I finally got the cable, RS had to order it and send it to me, got the 70.000 freqs programed in, but still nothing. Maybe I'm just to far out to hear em. Oh well.. I can still hear dispatch pretty good.

Here you can see the sensitivity test for the extended range on the Pro95. At 70 MHz the signal voltage is 1.4uV, you would like to see this number below 1.0. If you are not close to the transmitter, you will not hear much.

ANY scanner not made specifically to cover a specific frequency range will NOT perform at optimum capabilities when "tricked" vias software to monitor that range.

Basically untill we have a SDR type of scanner you have to put up with the limitations of current scanners.

Well, your right. It didn't work for me. So I have deleted the freq's from the bank. I'll have to figure out something else or not worry with monitoring them in my area. Thanks.

 

[ShawnCowden]

that means win 96 that put 700 mhz on our scanners are gonna be less sensitive.


also maybe thp will switch to a new system soon

 

[INDY72]

First part- EXACTLY
Second part- THP is working on an Motorola ASTRO 800 MHz Smartzone but its a LONG way from getting proper funding for buildout.

 

[ShawnCowden]

do u think win 96 will ever be able to make it where u can trunk 700 mhz ??

im sure a 800 mhz antenna will improve 700 some what

 

[INDY72]

I would not bet on the 96 doing 700 properly.....

Eventually GRE or Uniden will freaking wake up and add 700 MHz properly.....

Yes an ant designed for the upper spectrum will help... but its the actual programming of the scanner's capability that matters. The 96/2096 Were NOT designed for 700 MHz, or Mil Air..

Folks keep whining about why cant my scanner wipe my booty????

Was that capability built into your scanner? Or did you use written secondhand software to "trick" it to do this? Or did you yourself add a hand on the ant thinking that would make it uberscanner?

Same applies to anything your scanner was NOT designed from the ground up to do!


It is the same as expecting an Motorola XTS3000 to be able to talk directly to an Jaguar HT in Provoice Digital on an EDACS system with ESK on it.. without any patching!

In other words.. its not realisticly going to happen!

I remember back in the 70's the THP out of Knoxville was simulcast/multicast on 155.505 in which you could hear both sides of the conversation. Was that a control link between sites or something else?

 

[aaronsnet]

I am able to hear the dispatcher of the THP in Knoxville without a problem, but I normally have to be within the same county of the state trooper to actually hear him talking on the same frequency. Its interesting.
