Something pulsing on 453.475?

Oh yeh, I forgot that part... LTR will save the world!

How could I EVER forget that!

I can't imagine that Windsor's system actually interferes with the Madison PD's officers radios. Are Madisons antennas for their system directional and pointing to the north? Is it just bothersome or is there loss of reception?

My understandiing is that a trunked system on shared frequencies is supposed to be noninterfering. I always believed that to mean the channel would not be assigned if another user is active on the system. I would imagine there has to be level of interference before the channel has to be reassigned.

I still can hear UCONN FD over the LTR Passport on Bloomfield's system. I can hear the keying, but then I am a casual listener and not a UCFD member trying to hear the system.

If you don't believe me, come down here and have a listen for yourself. It is on the repeater OUTPUT so it isn't preventing officers from calling in. However, it is effected talk-out from the repeater to mobiles/portables.

The digital crap from Yonkers isn't helping either.

Matt and Mike,
I get the key ups on Madison all the time. Haven't heard Yonkers. Matt you sure its them? Being right by the pond, I'd figure I'd get all the interference.

Hi JOe:

Its definitely Windsor, that much has been proven.

I am involved with a couple of 452 channels over here that also get torn apart by the 2 second burst. And every morning at 0700 there is a 1 hour stream of data oan one of hte channels.

If I wasn't such a suspicious individual, I would venture to guess that when the coordinating association saw the list of around 100 or so frequencies, they saw $$$ and didn't bother to look at the proximity of other users and the possibility of destructive interference... and say "no"

of course, we could always throw a 5kW amplifier on the output of the repeaters getting hammered down here! (oooooh)

keep smiling... it confuses everyone else!!!

73, catch you for coffee one of these days real soon..

My question wasn't whether or not you could hear them, but if they actually caused interference. (Of course, if you go by what appears to be the standard set by the FCC vs Nextel, that is a pretty high bar). It is pretty poor for a system to cause problems that far away.

There are several frequencies in the UHF business band that have several LTR/LTR Passport systems on them and there seems to be no attempt to keep any interference from going on.

Still waiting to see what Windsor is going to do with the system as it appears to be still sitting idle.

Good point. The Madison system could be rendered totally inoperable and they wouldn't do anything. The FCC's response would be something like:

"We have determined that there is a possible problem. After spending millions of tax payer dollars to come up with a comprehensive solution, we have decided to give Marcus Speactrum the entire UHF band. He will then put all the agencies and buisnesses he displaced by this ruling on one of his save-the-world LTR systems."

those bursts are annoying, they are part of the LTR system that is being put up by Marcus...covering most of the reigon...i think the farthest allocated tower down south is Haddam (although at work i had my mobile pick up something down in Fairfield county - and a kid actually ID'd on a linked system outside of Cedar Sinai, and got dispatch).

windsor will be idle for a LONG time, atleast till they get the bugs worked out in the reigon.

and cg - as far as the freq. allocation for LTR, the only people that will have problems with LTR interference are non LTR users should a freq. matchup occur. What matt is getting is true, i was down in the area and actually snagged the newington tower's output from about 30 miles away. The reason you can hear the local yokel's up at UCFD on the windsor system is that the trunked freq's for windsors system are the same as the UCFD channel (i think)...as the trunked radios are recieving CSQ on those channels, they will pick up UCFD should they talk.

Windsor's system is not part of the Voicelink Network. http://www.voicelink.net/ It is a standalone LTR Passport system. There are going to be Windsor and East Windsor sites on the Voicelink net but last time I checked, it had not yet been turned on. I haven't monitored Windsor in a bit to see if they are back online yet. Bloomfield obviously is still adjusting their system.

It was Bloomfield PD (conventional simulcast 460.5125) that was cutting through on my scanner to Granby PD (460.5250) Now they have made that a trunking channel at far more than the 2 watts they are licensed for. I was in Bloomfield yesterday and my Maxtrac couldn't copy Granby PD due to the interference. (5 miles from the Granby line)

One of the selling points (at least with the East Windsor system) was the "automatic" switchover in case the primary system failed. It was been reported that the backup system is the Voicelink system.

I'd be interested in how that's licensed for both public safety and commerical uses, if that is the case.

East Windsor is still in the "wait and see" mode last I heard, with the outcome of the Windsor install.

I wonder if our system fails over to the voicelink network? Am i wrong in assuming that the systems (while data compatible) could fail over to each other .... :?:

 

[nmfire10]

But it isn't just a normal LTR system! It's a high tech anti-terrorism save-the-world-marcus-LTR system! Hahahaha.

Ok let's talk licence A system is not licenced the frq's are

 

[nmfire10]

Umm, ok. What's your point?
