All Activity

I have the QYT KT-7900D which is a tri-band (140/220/440) rebranded version of the DB25 and the BTech UV-25X4 and it's fully supported by CHIRP. It's not a bad radio for the price, but it has some behaviors I don't like. If you're monitoring more than one channel, whenever any monitored channel breaks squelch, the radio goes to that channel and there's no way to leave it until the squelch closes. I don't care much for that. Also, it scans very slowly; so slowly that it's nearly useless. I ended up programming only channels in the 1.25 meter band and using it as a dedicated 1.25m radio. In that role, it works just fine, since only monitoring channels in one band means I get less unwanted traffic "trapping" me on a channel. As a dedicated GMRS radio, it should also work just fine. You'll probably want to only monitor no more than two channels at a time, though; the quad-watch can get overwhelming. If I were using it for GMRS (which may happen), I'd monitor a couple of my favorite repeaters and leave the other two channels set to something I might want to switch to but not continuously monitor. It does output the advertised 25 watts, which is refreshing. The receive audio isn't the best, and I have to turn the volume pretty high to understand it. Transmit audio seems to be just fine, though. It receives about as well as my other radios. Overall, it's a decent radio for the price. For $90, I really can't complain. Interestingly, it's $11 cheaper than the DB25-G, at least on Amazon, although Radioddity offers some bundles which are less expensive than buying the QYT and accessories separately.

The StingRays used today can zero onto someone and track them within inches.. Cops can use StingRays to also identify the activity around crime areas, i.e. a guy throwing rocks and bricks at law enforcement cruisers. How did they do this.. video surveillance (either private or public) provides a location, time, date, the crime and even video footage, in this case a masked person. Police match video evidence to that what StingRay provides , a date, time and exact coordinates of person committing a crime. Further investigation reveials who owns the phone creating all this criminal activity. Bingo,, Now the cops have somone they suspect and want to talk to.. Now this is a scenaro played out on X how they found the guy..

During WWII the Germans used DF equipment to locate resistance radios. But the resistance also used radios to ensnare folks into traps.

Yes it can be confusing. At least Midland puts a chart in their manuals, that does help until you learn the codes.

I have several LifePo4 batteries. I have a 100 AH and a 50 AH that I keep in the shack for when I need them. I have a go box setup for portable radio with two 50 AH batteries and an ammo can style battery box with four 10 AH batteries hooked up in series. My next project is going to get some solar panels for my portable setups.

Every branch of the military definitely has DF capabilities. What capabilities they have will depend on the type of unit it is. But even combat units such as infantry and armor units have at least basic DF equipment. Now once you get to intel units, they will have all the good stuff that will find someone in a matter of seconds. I don't see most state and local law enforcement having the equipment for DF since it can be expensive. Federal agencies will more than likely have DF equipment. It will depend on the agency on what capabilities they have.

Having 2 is nice. You can have one charging while using the other. Swap out when it dies. My 100Ah setup will eventually be a 48 volt system.

The different terminologies can be confusing, especially when a manufacturer uses something completely different and you have to look it up in a table.

I now have two 50ah LiFePO4 batteries which should work better, but I haven't tried them yet.

If I need battery power I have four 100Ah 12v LiFePO4 batteries. They really hold a charge well. Been at full charge for a couple of months now and basically no depletion. So it's a great standby backup for me. Eventually one or more will get hooked up to my repeater. I also have ten 100 watt solar panels and a 40 amp solar charger that can be deployed at anytime. Again, eventually that'll go up in my backyard and supplement my household.

They can, but I'm guessing it was because I was using the "cigarette lighter" socket. It's something I got really cheap and they probably cut a few corners. It will crank my car but not my truck, so it's not the greatest starter pack in the world, but it's small and cheap.

It wasn’t that they didn’t try. The code wasn’t like other radios. The programmers hit a wall, multiple tickets had been opened but progress stalled. A few months back RT Systems cracked it and came out with a Windows version on their site. I suspect this enabled the Chirp team to finally move forward..

Using two-way radios may not be of a benefit when sophisticated DF gear is used. The local PD likely won't ave this kind of gear, but the US military, including the National Guard, might. Things get really crazy they will start looking for people. One example is this brochure. The portable units can act together in a networked configuration for faster and higher accuracy location determination. https://scdn.rohde-schwarz.com/ur/pws/dl_downloads/pdm/cl_brochures_and_datasheets/product_brochure/3606_9591_12/MP007_bro_en_3606-9591-12_v0600.pdf

Well, CANG and USMC do have CEWI BN's, right??? (although the nomenclature may differ)

Click on the repeater. Click on View Details. Click on Request Access.

How does one "request access" from a repeater owner? I'm looking at the map...I've made a list of repeaters I'd like to get access to, but I don't see a way to request access from the owners. DISREGARD

Now that Chirp supports the DB20-G it is literally the best choice analog GMRS/Ham Radio dual bander for the price!

This is correct. A phone that has been turned off but still has its battery in can be traced through the built in GPS chip. And most new phones don't have an easy way to remove the battery. As far as the rioters using GMRS or amateur radios without licenses, I don't they even care.

Surprised it wouldn't put out full wattage. Those packs can put out some good amperage.

It's just a ping. Sends out the phone ID, ratting you out. Yes it would make it harder, but not impossible. Best option is to leave your phone. And while an HT is an open communication it doesn't ID itself or give it's position away easily. You can communicate discretely while not technically legal it gives an alibi.

That doesn’t mean that you can’t replace it yourself for just the price of the parts. See if the LED is getting voltage. It’s probably less than a volt to turn on and under 1.3 volts (dc) at max brightness. If it’s not getting voltage then it’s probably one of the chips upstream. Just trace them upstream. Or just start by changing the LED.

As long as they don't use on of those radios wtih GPS in them

Afraid not... oh well; will probably buy another one. Maybe I'll try a Retevis and see how they hold up.

Yeah I checked that. Thanks!
