Low band fire signals

Greetings everyone. I just joined & love the site. I've been following the skip conditions postings along the east coast & was wondering if I hooked up a Maco M104C CB antenna to my Uniden BC785 scanner & pointed it northeast would I be able to receive low band (33MHz & 46MHz) fire departments in Pennsylvania, New Jersey, New York & Connecticut? The Maco antenna has 14 Db of gain & I would be using 50' of RG8X coax. I live in Palm Coast Florida. Thanks in advance.

Well, you would probably be able to providing the band conditions were open from that area to yours.

On a normal day? No way.

A CB antenna jus' ain't gonna cut it good buddy, you need an antenna appropriate for whatever band(s) you're using. Otherwise you may as well use a hunk of wire for all the good It's going to do.

When the conditions are right almost anything works. I have a 6 meter beam that gets much of the 45/ 46 MHz stuff and 10 meter antenna that hears 33 MHz fairly well.

I cut my old CB Antenna to 33.86 MHz in the late 70's. Activity there was a lot more than it is now and reception was unbelievable under normal conditions, never mind any skip conditions (LostNooYawka - if you REALLY want to hear anything, get a hacksaw and saw off 21" From each element... that won't help your CB any... in fact you won't be able to use it on CB anymore, but will work great for 33 MHz).

Thanks everyone for your timely & very informative replies. 902, I've gotten word from a number of commercial & amatuer radio operators since I posted my query who agree with you, they state that exact frequency antennas are primarily for transmitting & for receiving purposes any antenna that maintains a capture surface area fairly close to the segment of frequencies will operate accordingly, any idea how much I should cut of off the elements for the second antenna I will be using for 46MHz monitoring? Thanks in advance. Hal (TLNY)

On another thread I've been talking to some guys in PA about the lowband traffic still in service in their area. Here in Texas, we get their skip on 33.90, 33.10, 33.74 and some other channels, but the past few months it's been very quiet. One of the guys says that the lowband skip conditions are quiet right now due to a low cycle. So I'm looking forward to the next cycle when I can hear the northeastern traffic again.

However, the short skip has been running rampant lately down here. I am in Midland, which is half-way between Ft. Worth and El Paso right on I-20. I've been getting quite a bit of traffic from the Central Texas area, as well as the Panhandle (Lubbock and Amarillo)....not to mention some traffic from Clovis and Portales,NM. All of that is on VHF-highband. The unusual thing is a bit of skip on 800. Midland has an EDACS trunking system, and I've been getting some traffic on one of their EMS channels. Haven't been able to catch an ID, but it's certainly not local; but I didn't realize that skip could run on 800 like that!

Newyawka: On lowband that CB antenna won't hurt anything, as the CB frequencies are all 27 mhz...but on AM, not FM. When I lived in Lubbock, I lived in a 7-story apartment building and was allowed to have antennas on the roof. I had an old Motorola lowband base radio, to which I connected an old plain-jane CB groundplane antenna. Not only did it receive up a storm...it did a fair job of transmitting as well.

Although 800 Mhz is subject to tropo, just as frequencies below AND above it are, that is not likely what you're hearing.

The City of Midland and Midland County have a patch set up between 155.025 ( PL tone 179.9 Hz ) and the city TRS to simulcast some fire (and police) dispatches.

The city's receiver on 155.025 was likely hearing another agency, via tropo, that operates on 155.025 / 179.9 . The RadioReference database identifies 4 agencies that fit ... in Colorado, Illinois, Indiana and Michigan.

Jeff: I'm well aware of the patch set up on 155.025. I have that in one of my conventional scanners. But what I heard was on the trunk...not on the patch frequency. One bit of traffic that I did hear an ID on was in Central Texas....but I can't remember the city now as it's been a week or so ago; but it was ambulance to hospital traffic.

Were you able to search nationwide for that freq/tone combo? I didn't know there was a way to do that. I certainly don't think you went state-by-state.

Gilligan,

To search nationwide open the drop-down menu with the state name and select "- All United States -" at the bottom of the list.
