First Impressions and Quick Review of the Baofeng GT-3 Mk. II

Hey folks,

After some mixed thoughts with the Baofeng BF-F8HP, I ordered the GT-3 Mk. II to compare the two transceivers.

The GT-3 Mk. II is a successor of the GT-3 with some minor improvements, most notably the stock antenna.

The package arrived wrapped to an inner piece of cardboard. Interesting package design that doesn’t require any packaged air.

Once again, the Amazon box had li-ion warning labels, which was a nice safety measure.

The aesthetics is the most notable difference between the BF-F8HP, which sports an all-black theme, while the GT-3 has yellow-orange sides with a keypad contoured with the same color. The UV-5R also has an all-black design with the exception of a glossy metallic speaker grill.

The colorful looks of the GT-3 makes it look less industrial than the F8HP, and gives it a slight tinge of playfulness, just like a yellow Ferrari. The GT-3 might be appealing to teenagers and younger members who want to get their hands on HAM radios.

Another noticeable difference is the display. It uses an inverted display, where the text is white and the background is dark purple. It looks better on the ads than in real life:

In reality, it’s quite hard to see when the back light is off. When it’s on, it looks very cool and uniquely different from the usual LCD displays:

However, the contrast becomes quite poor when the back light turns off (1-10s configurable timeout), and the characters that are supposed to be white aren’t very reflective without the back light.

I found the GT-3 Mk. II quite hard to read when walking in the dark. When I pressed a key or received an incoming transmission, the back light would turn on and it would be great, but otherwise it bothered me.

One nice improvement was the rubberized volume and power dial. It provided great grip and I can able to turn the radio on effortlessly compared to the F8HP and the UV-5R.

Comparison of antennas. GT-3 Mk. II, BF-F8HP, and the UV-5R.

The antenna is supposedly a re-branded Nagoya NA-666 also known as the “Antenna from Hell.” Despite its nickname, it’s performance is quite respectable, although I haven’t tested it thoroughly myself. I found it to wobble around too much while I had the GT-3 clipped to my pants. Might cause unwanted attention, maybe not.

Pros:
-Identical responsiveness to the F8HP.
-Has a physical Band Select button, although the Band Select menu item doesn’t work as in the F8HP.
-Decent stock antenna
-Rubberized volume/power dial

Cons:
-Low contrast inverted display, hard to read when backlight is off.
-Display dims whenever receiving or transmitting a signal.
-Floppy antenna

It’s a very tough choice between the GT-3 Mk. II and the F8HP. I’ll have to return one of them, but I’ve still yet to decide. Thanks for reading the brief review.

Is this some kind of ‘walkie talkie’? What is the range?

It is a handheld ham radio transceiver. Handheld Tranceiver. HT. Or as you say, a small walkie talkie.

These operate on both UHF and VHF. In some countries they can only be owned and operated by licensed radio amateurs. In other countries they may be used on some open unlicensed frequencies.

The range is limited to a couple of kilometers, depending on the terrain. Since the wavelength is short things like buildings, mountains and the curvature of the earth will limit the range. You can extend the range very significantly (>2-3 times) by climbing up on a rock or a hill or by using a cable to an antenna that is placed high up. Or an external magnetic antenna on a car roof. Higher output power doesn't help as much as a better antenna and especially a better antenna higher up.

27 MHz CB radios have better range since the transmission is not as limited to "LOS", Line Of Sight, as higher frequencies are. But they are bigger and much more clumsy.

Radio amateurs can also access repeaters, much stronger radios operated by radio amateurs with bigger antennas high up that automatically repeat the signal and can send it very far and also receive and repeat answers.

A couple of cheap HTs is perfect for a group that is fishing, playing paintball, geocaching, hiking or hunting in a limited area. Or at a building site or some form of event. The HTs will have to be programmed first, so they all use the same channels and call filters.

The price range for HTs is extreme, but the difference in performance not so much. Similar to flashlights. Baofeng is a high volume budget brand, but their radios are still very capable. Sometimes better than radios that cost much more than 10 times as much. A little like something between Conway and Fenix for flashlights.

If you have no previous experience, the learning curve will be steep. There are plenty of resources on the Internet.

If you decide to try, and it is legal where you live, get two UV-5R first. They have perhaps the best capability/price among all HTs. Program them and get them working and try them out. Buy a programming cable and download "Chirp". Then, if you decide you need something more or better, perhaps waterproof, sell them or give them away and buy something better. This way you make sure that you don't buy something less capable than an UV-5R for a lot more money. That is otherwise very easy to do...

Or keep them as spares or loaners. The UV-5R can operate fine together with many other radios that also use VHF and UHF. For instance PMR-radios or hunting radios on VHF.

The UV-5R is popular because it is "good enough" for many purposes, and very cheap. And it has a huge range of alternative battery packs and other spare parts. Using special battery packs you can run a UV-5R from Ni-MH AA or AAA or 12 volt car battery. Or just a bigger Li-ion pack.

I have always wanted one of these. I have a few shortwave receivers/radios but nothing to transmit with. I am fairly sure we need a license to transmit here in the US, maybe not all frequencies. These are recommended for disaster preparedness , I guess you can call for help if the phones are down.

If you are very, very lucky, perhaps. But I doubt it. The main use, if you're not a licensed ham operator, is to get a couple of HTs and set up local communication between them. And use them in a group/family to keep in touch in a limited area.

So you should get at least two, program some channels, and have some talkative friend nearby you can hand one of them to.

If you are a licensed ham radio operator you can use one to talk to other ham radio operators far away via repeaters. But if the phones are down, then most likely the repeaters are also down...

However you can use these HTs to listen to FM broadcast as well. In some regions/countries there might be local emergency information distributed that way.

I got to craft together a programming cable. They’re normally sold for $5-20 but I was pretty sure I had all the parts around.

At the heart of the cable is an FTDI USB to RS232 converter:

At the end were a 3.5mm and a 2.5mm audio jack, normally used for the headset and mic accessories.

I wasn’t able to find a 2.5mm to 2.5mm audio jack so I settled for a 2.5mm to 3.5mm adapter in Robotics Club.

I soldered the wires and shrink wrapped them. I was surprised that the cable works well.

Programming the radio using Chirp make it a lot more useful, especially being able to input custom names to memory channels.

it is a hand portable HAM radio, lovingly known as a handy talky

Amateur Radio Frequencies…if dual band…it even covers those ultra cheap FRS/GRMS radios people use but have woefully bad range on them

Learning how to make DIY makeshift antennas can REALLY boost performance from those woefully inadequate screw in whip antennas

Heck even this and a few feet of coax can triple the range easily! (+10~ dB gain over a stock rubber duck)

oh yeah, there is also a way to tie a cell phone into one of those cheap handy talkies for APRS

and using APRSDroid or one on iPhone

This thing is cool for about the first five minutes. I am now on my second one and the call and moni buttons are now not working. Since I am a Tech Class waiting on my license to be posted, it will be interesting to see if the PTT craps out as well.

Not a Happy Camper…
