The repeater I ordered was new and apparently they got a bunch of defective duplexers and needed to replace them. OffroaderX can tell you all about that. So the company just sent me a new one already tuned to receive the GMRS frequencies.

I would actually like to get one tuned to the frequency I use to see if it changes anything. Not planning on moving the frequency anytime soon so a hard tuned duplexer would be just fine. I would just remove the broad tuned one out of the machine and replace it with the single band tuned. Pretty simple operation. Probably less than 1/2 hour. That's about what it took me to do when I didn't know what I was doing, although not knowing what I was doing was just based on never had done it before. It's just removing some screws, swapping out the coax one for one and returning the screw back in place.

I have the Btech RT50 and it has a full spectrum GMRS duplexer. It says it's rated at .25µV at 12dB SINAD. Can't say I can prove it but it seems to receive well for the antenna and it's height. This is the replacement duplexer they sent me. The originals sensitivity was much worse than the replacement. Tuned full band.

All I got was a card and love from my family.

It might be difficult even for a few krakens to locate FRS/GMRS radios especially if there are many signals on the same frequency. Lots of "ghost" signals that keep moving around. Maybe 3 airborn detectors triangulating with high power optical recorders might be able to do the job quickly. And I don't doubt they have such a system. But with lots of radios out in a relatively small area it might be difficult to lock on a single tranceiver and even harder to hear a single transmission in a sea of similar signals. Don't use a roger beep or any identifying transmission.

Most radios have a physical off switch unlike phones which have electronic on/off switch. No power is no reception/transmission. They could sneak in a bypass resistor to keep the power on for the GPS.

Just asking. Not sure how the GPS would work or be stored, or not. In a phone it's extensive. Goes back days, weeks, months.. I'll bet it's just on the spot for the radio.

Wonder if it's hardwired in there that law enforcement could force the info out of it with a special code.

I would say a 2 way radio is harder to find than a cellphone is. You can ping a cell phone at will with the proper equipment and have it give it's position away. You can't do that with a normal 2 way radio.

Cell phones work very well at -107dBm and OK at -115dBm and at -120dBm it's getting iffy. So a 50-60dB drop may not be enough in a lot of situations. But you'd have to be pretty close to the cell tower for it not to go below -120dBm in the bag. A -60dBm cell signal is usually right on top of the cell tower.

Probably why an EMP bag will let high frequencies through at strong signal levels. The bags are designed for a dc generated pulse.

Stopped them dead in their tracks.

OK, so barry's philosophy of you didn't build that. You know what I mean.

I've had them say to me well I had to pass a test and endure ongoing education. Well big whoop. I had to learn my trade 100% on my own without help from a myriad of teachers and employers. School of hard knocks as it's known. I'm sure they'd have a harder time with my profession then I'd have with theirs. Love it when they say carpenters are a dime a dozen. Ya, crappy ones maybe.

And you shouldn't be. Plumbing and electrical aren't really that hard until you get into big commercial. And the majority of people don't do the big stuff, only residential. Most competent people could do plumbing and electrical and get it done right. Biggest hassle is the ever changing code book.

Just like anyone who has to pass a test to get a license they look down from their pedestal at you like you were trash. I see it in the contracting world all the time with plumbers and electricians.

That's only 4 paragraphs...

If you leave it at home you have an alibi also. I was home, check my ping...

Radio Dork?

Just program them in groups. 1-100 is GMRS and 101-200 is MURS or whatever. That way you don't need to remember a weird channel number. Always starts from 1 and goes to 100. Just ignore the 100 on the MURS.

This guy might have busted himself https://rumble.com/v6uoh8p-nyc-riots-paid-protester-comes-forward.html This guy definitely did, with a smile on his face at that. https://rumble.com/v6uoh6v-la-riots-paid-protester-comes-forward.html

Sure they would. It's the govt.

FM-CB/GMRS combo radio....

They had a net going on? News to me.
