Hello all,

 

So, I'm in East Haven CT.  On my way home from work about 1230-1300) I listen to these two operators talking on channel 17 (462.000). Been listening for about 2 weeks. Now my MXT400 has 3 power settings, low is about 3w, med is about 15w, and high is about 40w.

 

I had the radio on low, when I could I keyed the mic, gave my call sign and said monitoring. Did that for a few days. No response. Then I went to medium power, same thing, nothing.

 

So today, 3/22/18, I listened to them all the way from about North Haven CT (about 1/2 way home). The closer I got to my house, their signal strength got higher, and then about 1000 feet before I got to my driveway, their signal pegged my meter all the way up. So I started looking for antennas on houses and vehicles, figuring these guys are right here, few houses away, basically right on top of me. Saw nothing.

 

Now I have lived here for 18 years, I know the neighborhood well.

 

I initially thought they were using a privacy code, I could hear them but they couldn't hear me..(if that's how the privacy codes work on GMRS)..don't know.

 

 Then they started talking about this last snow storm. Now in East Haven we got maybe 3 inches of snow. They were saying they got 14 inches. I said whoa, 14 inches, where are these guys??

 

Then one finally said......."yeah here in Suffolk County we got hit good". Suffolk County, that's in Long Island, NY. So I checked the distance, from East Haven, CT to the closest point in Suffolk County is 50 miles as the crow flies.

 

Sooo, if they are on ch17 GMRS, their signal is knocking my door down, I hear them crystal clear, and I keyed at 40w....how could they not hear me????????

 

Now if this was my CB, ok, I get it, I'm "shooting skip"........I have talked from CT to Indiana on skip...................but how is this working on GMRS??

You are hearing a repeater output. they can not hear you unless you activate the repeater input on 467 with proper PL.DPL tone.

Lol. Wow a bit shocking. Logan5, how far can you reach on high without repeater? I could just imagine your face when that meter pegged. What are you using for a mobile antenna? I have a friend in Groton that I'm trying to get him to buy a radio so we could talk. We use to talk on the CB back in HS. He is an Engineer for GDEB.

Two yagi antennas pointed at each other one 25 feet and the other 35 feet @ 5 watts really only 3.7 a lil over 11 miles, with the limited height it was only 4 out of 5 but usable, now that I have 55 feet on my end is 5 out of 5, but we use the repeater, as a dedicated link takes up too much tower space. I truly wish I had access to the roof of a 12 to 20 story building, then I could do other UHF stuff with my tower. I shut down from time to time to scan the other GMRS channels, has been a wile. got a Mag NMO on the truck, use a cheap window clip in the new SUV, around the house, I use low power 500mw and a unity nub BNC antenna. Out and about I use the typical soft rod 12 inch antenna in the BNC version

just as a reference,my midtown machine can be heard and talked through in Patchogue LI on the south shore. roughly 55 mi.

you're ~25mi from the north shore and ~35mi from the site you were hearing.

Hi Logan5, the repeater would explain how my meter is pegged. I hit them several times wide open ch17 at 40 watts, got nothing. So how do I find out the PL.DPL tone to talk with these folks?

 

Couger100101, on my Interceptor I'm using the Midland MXTA11 27 inch 6dB gain, mounted on the trunk lid through a hole with a NMO mount.  Of course the radio is the Midland MXT400.

Not surprising, there are several repeaters on LI that are on really top-notch tower sites and are heard for quite the distance. Based on your location its not impossible for you to be hearing these repeaters full-scale.

No doubt gatekeep, I have been operating high end CB radios for nearly 30 years, these guys from Suffolk County were blowing my doors down. I just don't know how to find out the PL.DPL tone of these guys. They are local to each other, like 5 minutes away.

Does that 400 have a tone scan feature? Is the repeater listed in the repeater directory? with UHF, if they are up high, the signal will reach you. And it's going across water so no obstacles...

Well, the 400 does not have a tone scan feature. I have no idea if their repeater is listed. All the radios screen shows is the channel I'm on, which was 17.

Channel 17 on most blister packs or radios that use Ch #'s have Ch 17 as 462.600.

Yeah I did check into that, yes ch17 is 462.000.    How would I go about finding out the repeater info to see if its listed in the directory?

If you can make contact with the repeater users again over the output, ask them for the repeater's tone and location. If it's a private system, they may not give it out. Alternatively, if the repeater sends a callsign, it may already be in the database under that callsign.

Broken segment on your MTX400 display, perhaps? 462.000 MHz is not GMRS, it is business land mobile frequency, under Part 90.

Hey JohnE, I looked at that list for NY, only Suffolk County listing was a closed private system started by law enforcement for their families. My search continues. Oddly enough, the MXT400 receives great, everything works, but to date I have not made any contact with anybody.

 

I have it set on "scan" and when it stops on an active channel, I wait a little and announce "WQYX865 listening"..........or "monitoring"........

I'm just a bit surprised that I cannot get any response. There is traffic here in CT on ch1,2,3,17,20. Maybe I have the radio setup wrong, I don't think I do................... :-O
