So what's you major malfunction with that?

If I can find this in less than 30 seconds I doubt anyone else will will have a problem either. https://fieldradio.org/unlock-baofeng-uv-5r-frequencies/

Yeah. If you have cash or a CC they'll sell you a radio. At least a few swaps I've been too, that give away radios for door prizes, will substitute a gift certificate equal to the cost of the radio if the winner is not licensed. At least on the way home they won't be talking to the local fire department, for example, on the new CCR they have no idea how to use other that turn it on and press the big button on the side to see what happens.

Correct. My buddy found out about it when reading the local news paper where the party involved used the interference to justify switching to a digital radio system. He showed me the news clipping. And no I'm not going to provide any details.

Some of my radios I've purchased new. Most were found at local Ham swaps or eBay auctions.

Point well taken. Before going off the rails assuming illegal operation one might have stumbled on a perfectly legal grandfathered system. If it bothers somebody do some research before jumping to conclusions. Even in the Ham world we have to be careful since Hams only have secondary status on the 70cm band, we share it with the primary user, government. I remember doing a frequency search a while back and stumbled across some public safety frequencies between 420 MHz and 430 MHz. The US Ham band officially runs from 420 MHz to 450 MHz depending on how close you are to Canada, Line-A. The 70cm band is a mine field of various users, technical requirements and restrictions. https://www.ntia.doc.gov/files/ntia/publications/compendium/0420.00-0450.00_01MAR14.pdf https://www.chp.ca.gov/find-an-office/central-division/offices/(420)-bakersfield https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf00049.html

The part that's sad is when people act like it's OK. That's how non compliance starts and grows. It can simply start with those that are licensed simply refusing to communicate with those who are not and using GMRS radios. I had a buddy that thought the same thing messing around with his UV-5R unlicensed. I finally got him to get his Ham Tech license and then he got his GMRS some months back on his own. He later found out the FCC was looking for the source of the unlicensed operations and interference. He realized he was lucky he quit when he did, had no idea about the complaints made, and got legal. The reasons why people don't bother, they think nobody gives a crap, nothing is going to happen me, and finally just being lazy and cheap.

So what else are people going to excuse because the rules are inconvenient?

And FRS is stuck with narrow band FM only and limited to a max of 2 watts.

I have several of those NX-300's. They are very nice radios. Might be a bit on the heavy side and a little bit too bulky for shirt pocket carry. The very narrow 6.25KHz NXDN mode would be a great fit to use on the nearly useless FRS/GMRS interstitial channels that are limited to 0.5 watts and 12.5 KHz bandwidth. The guard band between the repeater channels is 5 KHz and the FCC emission for the very narrow NXDN mode is 4K00, which fits in there with no adjacent channel overlap compared to the narrow band FM currently allowed at 11K0. Now all we have to do is get the FCC to change their mind.

A little sagging but still looks good.

They were both involved with a person with the last name of Fieger. However one is a well known lawyer (Geoffrey Fieger) and the other (Doug Fieger) is a musician.

And maybe visit from Jack Kevorkian, then a ride in his van afterwards.

These guys might be sort of busy. There is a large NXDN digital voice linked repeater network right in that area. If you have a hotspot or an NXDN radio with access to a local networked NXDN repeater you could monitor the activity. Checkout the map further down the page for the covered zones. https://ni4ce.org/nxdn-digital-communications/

I think my collection is around that too. Mine are mostly Kenwood. I have a few Motorola's and some Chinese ones. I've been looking at getting more digital radios. I have way too many FM ones as it is. I don't have anything for YSF yet, all the other main stream stuff I have, D-Star, DMR, P25 Phase 1, NXDN, in both VHF and UHF models. I've been looking for some dPMR radios but they are almost non existent in North America and are mostly a European thing.

The antenna needs a ground plane, or the equivalent, to work. I've tested a lot of hand held radio antennas with and without a ground plane. Just about everyone resulted in a crummy match except the 1/2 wave types. I had thought that a good ground plane would yield a good match, nope. Some tested better when stuck on the back of my hand, see sample photo, verses a large sheet metal ground plane. I'm guessing the antennas are specifically tuned to use the small ground represented by the metal body of the radio and coupled into the users arm while hand held. I wouldn't depend on the coax shield either. You get RF on it which feeds back into the radio resulting in "undesirable" operation. For the NA-771G you can try a tiger tail. I'll suspect as the tail moves around the match will change a lot too. If you have a backpack with a good sized metal frame that might work as good if not better than the tiger tail. 483039407_AmateurRadioPedestrianMobileHandbook.pdf

For fiber glass tops a good choice is a 1/2 wave antenna. They typically don't really need a ground plane so you have much more flexibility in mounting locations.

The design of CHIRP only gives you access to a subset of the features in many radios. If you want to use all of the functionality of your radio I advise you use the manufacturers software.

I don’t own any “purposely manufactured” GMRS radios. I use new or used commercial gear, many with Part 95 certification, programmed for GMRS. Generally the commercial gear works better, has more features and more flexibility. A few of the hand held radios I own are 4/5 watts with up to 512 channels, plenty for any uses I need.

The various digital voice modes use variations of FDMA modulation. In the case of DMR it’s also done in 30 milliseconds bursts per time slot. Since the frequency shift is done directly on the carrier, it’s not audio frequency shift keyed, and the bit stream there will likely be very low and high frequency components. The radio’s Discriminator will try to decode it as audio. The high and low frequencies will get filtered out by the audio circuits so when applied to the transmitter there will be high data loss, missing data bits. The loss likely will be too high for the RX radio to perform adequate error recovery so the communications fails.

This is what I read: If you are a licensed amateur in the Philippines, you can use these frequencies legally. 144–146 MHz (all classes) 420–450 MHz (Class A,B, C) ———————————————— In many countries Hams are limited to 430 to 440. I think some of the older Ham gear in the US had the same limitation. In fact checking some of the recent Chinese radios, where you select the “mode”, you’ll see different ranges for VHF and UHF.

You sure about that? To date there are no digital voice modes authorized by the FCC for GMRS. If it’s being done by the city are they operating under a grand fathered license? Checking the FCC database should show what frequencies are licensed and emission mode. The later will be the clue if they have authority to run digital voice.

Except towards the fringe of the coverage area. That's the attraction, better audio when the simple FM signal starts going into the crapper.
