New Tower

Shively
Old Manslick and I-264 226 New In progress


This tower is in place and has the microwave links and other antennas on it ready to go. My youngest and I watched 3 guys climb to the top of this thing hooking all kinds of stuff up. I will try and take a pic and send it out as well.

Tech's on TG 19

I heard tech's talking today on TG 19, also heard another TG once.
They were talking about swapping or setting up radios. The downtown Louisville site also was down this morning.

And the Tech's have encryption capability, so I imagine the whole system could have it.

At least there is some progress. ;)

They have or will soon be, "moto-bridged" county fire 1, 2 and mutual aid, as well as EMS 10 to the new system. It is being done for more testing. Any comments on quality are welcome. The quality may not be the greatest due to patching.

Actually, the little that I heard was not too bad. Except for the encryption part. ;)
Now the analog to digital delay would be maddening if I was listening regularly to two radios, one digital and one analog.
And I guess just comment here?

I have a tower right outside my window almost. I watched them build it but have yet to take pics. I am going to the car show tomorrow and should have my camera, I will try and take some pics of the tower....And some cars...lol...

I heard the encryption the other day. I think I know which ones use it and which ones don't.

Sounds like we have some good listening ahead of us.

Here's a question that's been bugging me for a while, after the new system is online and the old VHF and UHF systems have been taken down how are they going to page out all the volunteer firefighters in Louisville? Motorola doesn't make an 800 MHz Digital pager as far as I know and I don't think that they will give a $5000+ take home radio to every volunteer in the county.Are they going to alpha-numeric pagers and ditching the radio ones?

They will probably leave the 4 VHF towers for paging. They could also go to alphanumeric paging. Most departments don't like this option. Might be the time to start asking so one could have input.
Also, I think they need the VHF for the setting off of the warning sirens as well.

But most counties keep their VHF/UHF for paging. The city FD will most likely go to something like this, either Zetron or Moto

As I no longer have intimate knowledge of MetroSafe, I would think since the paging system is the Zetron system and they will more than likely continue to keep the vhf licenses, that they would either simulcast the dispatch channel or just dispatch straight off the vhf system and then switch to the 800 for the rest of the traffic.


The console radios that they use at MetroSafe are Motorola touch screen radios with infinite room for expansion. Very nice setup and extremely easy to use.

Pagers? We don't need no stinking pagers.

The tone and voice pagers carried by firefighters will continue, with one heck of an improvement. Radio shop Ron and his crew have come up with a federal grant to improve the tone and voice paging for firefighters. The new set-up will be a five (5) site simulcast system as compared to the three (3) site single-cast system we now have. The coverage maps look awesome.

While this is kinda separate from the MetroSafe radio project, it will be done as a change order. Yesterday I was told they hope to have this up and running by the end of the year. It will be on a new frequency 152 something or another (an abandoned paging channel I believe).

If this got done yesterday it wouldn't be fast enough. Moments ago our department was dispatched to a fire. The pager I have in the basement did not go off, but the one upstairs did. So an improvement in the coverage overlay is more than due and Ron I love ya for that!

I haven't heard anyone promise this yet, but it's pretty much a "no-brainer". I imagine they will patch the VHF dispatch channel (the pager one), to a talkgroup, so what is being said on that dispatch channel will also be heard on that dispatch talkgroup.

I suppose I won't get shot because the papers that I got yesterday were not stamped "Top Secret", but here's an update of the Radio Project:

The remedial tower work at Meidinger, Waverly Hills, Mitchell Hill and the transmitter shop have been completed. I don't know what needed remediating, but whatever it is, it's done.

The Fern Creek station 2 tower, the Manslick site and the MSD Tower sites are complete. The Hopewell site is supposed to be done 8/8. These are the newly constructed towers.

There are four other sites which are co-location deals with cell service providers. There are lawyers involved signing agreements, and as you can expect with lawyers involved, things never move swift (other than their bills).

There was an issue with the original Utica site and they had to come up with another site, so that's led to a slowdown. They hope to have this new site and the four above completed (from a construction standpoint) by the end of this year.

They will be finalizing the radio counts during the months of October, November and December.

The master site renovation is scheduled for completion March of 2009.

They hope to have the fleet-mapping done by March of 2009. (That might be fun).

Acquisition of subscriber equipment (I don't know why they can't just say the portable, mobile and base radios) will start January of 2009.

The radio programming (that might be even more fun) and distribution with begin April of 2009. That will also be when the formal testing begins.

What they are going to do, sounded funny in the beginning, but makes a lot of sense when I think it through, is issue the public service people their radios first. So they will be the proverbial canary in the mine. I'd rather have them discover a flaw instead of public safety.

That's my story and I'm sticking to it.

So I'm guessing that during the "Formal Testing" the old V/UHF systems will still be operating at the same time (simulcast) or will they shut everything but the new stuff down for the testing? I'm trying to guage how long I have before I have no choice but to get a P25 scanner.

My guess if you want to begin listening, January 2009, but these things always run behind.
I would start counting pennies now. Lot's of P25 in Louisville, Knox, other un-identified traffic, Safe-T digital, and KSP.

I think there is enough (traffic now) to justify it... to yourself... but the wife or significant other, bills to pay... well that's another story. ;)

Chief: Has there been any serious discussion on the digital vs. analog issue for fire fighters at a working fire? My link to the report doesn't work any more, go figure! But given the number of basements and high-rise buildings in Louisville I could see some possible comm problems.... Lexington has enough trouble at times with basements and high-rises with an 800 analog.... (Sometimes I think it would work better if they'd designate a few of their freqs for use as scene operations... put vehicle repeaters in each of the District Majors' Vehicles and operate as conventional pairs--they already do that with their talk around freqs; then, maybe put it on a talk group so the bosses can hear, but keep the folks in the fire safe)

I imagine that they will keep the VHF and UHF systems up and running for a period of time, hopefully patching the new system with the old as much as possible. However, Newsalan offers the same advice as I would.

The purpose of last Friday's meeting was to address the digital-analog issue with the Motorola factory folks. It was said that since May, Motorola upgraded some of the innards of the radios in hopes of improving the situation. I got the impression that Motorola has put a lot of effort into resolving this problem.

We are going to be trying some different things, such as programmable settings, with the few radios we have, just to see what might work best. So that's why they have done the patching.

It was also said Friday that there will be some simplex/analog channels available and programmed into the new radios for use in bad areas. I'm thinking that the magic number often used is 95% coverage, meaning there isn't coverage in 5% (and I'm okay with that, it's just the facts of life), and these simplex channels will overcome that 5%.

That's awesome, Chief.... ironically, i noticed the same problem with my shotgun mics a number of years ago when we switched to digital recording.... my communications isn't of a life-or-death nature (although bad sound is never good for TV) and originally didn't equate the problem as being a "digital thing" as opposed to just the switch in cameras until I looked at the sound on a scope.... wonder what throat mics would do to solve the problem...
Plz keep us posted, I know there are a number of firefighters who watch this board and a couple have asked me about the problem based upon their reading here....

I don't want to get a digital scanner at all but I'll have to. I just want to get an idea when dispatch and ops on the analog system will be discontinued.

This radio APX7000 P25 Multi-Band Radio from moto has two microphones, spec sheet say to improve sound.

It's something they need to fix, but I'm not sure cities and towns can pay the price for fixing it.

The moto guy said that the main culprit is the background noise may be louder than the transmitting person's voice, thus resulting in the garbage. So we'll have to learn to speak a little louder in high noise environments.

They also said throat mikes do resolve the problem, but in their testing, they found that they may not be the best answer for the fire service. If a firefighter who is wearing full protective equipment snags the cord from the throat mike to the radio, on something and dislodges it, putting it back is difficult because of the gear.
