I've fired up CHIRP and have a few repeaters setup. So far, so good!

A jack of many hobbies and a master of none - spending lots of time on amateur/ham radio, running, and technology.
I have had my GT3 for 3 weeks now. I'm very pleased with it, The new hardware inside is different. It seems a bit quieter and more stable, than other models I have purchased from Baofeng, and the audio volume is comparable to the UV-82. The software features are similar to previous Baofeng radios. It is easy to manually program. There is no "free" Baofeng software for this GT-3 model yet. Chirp does not have it yet either. I chose RT Systems programming software, which make it very easy to program. I have used it on a local repeater systems here. And changing repeaters is a simple process. The screen has a black background, and is very easy to program by computer. Transmitting is clear, and other contacts have said the audio is crisp, and quite running at 5 watts. I have used the radio for simplex operation, and clarity of voice on flat open terrain is exceptional for 2 - 4 miles. Repeater operation is solid also. I also like the Baofeng UV82. In addition I have a ICOM ID 51 D-Star radio, but find myself on the Baofeng's most of the time for general use. Also because I cannot use a earmic on the ICOM radio without an adapter. Overall I'm very pleased with this Baofeng GT-3. Top items that make this radio very worth while:
1. Light weight, (Due to the closed cell plastic)
2. Compact size (Even the rubber antenna is small, but does not compromise on gain).
3. Improved hardware exceeds previous models.
4. Unique look compared to other Baofeng radios.
5, Better hardware and performance for 2014.
The Chinese seem to be listening to their american customer pool.
Brick i just got mine today, Cant go wrong with it.
Pros:
The squelch works now.
Audio sounds much tighter now on the RX at any volume
The radio is more sensitive (at least to me it is)
I can see the screen in very low light when the backlight is not on
The feel of the radio is nice.
The light is much brighter
Cons:
The stock antenna is still junk.
I don't like the rubber around the main knob
Hopefully the silk screening on the keypad does not wear off like the other models do.
"My observations so far.
#1 Same poor performing antenna as what people refer to as the UV-5R "stock"antenna (it's the Baofeng UV-5R Logo antenna)
#2 Battery/charger is not compatible with UV-5R batteries at all - nomodification possible that I see
#3 Speaker sounds a lot better to my ear (I have some high frequency hearingloss and I hear more low freq on the GT-3)
#4 Had to trim my FTDI cable jack as the radio case around the jack is atouch deeper than the UV-5R so the top pin wasn't seating fully
#5 CHIRP speaks to it as a UV-5R
#6 Firmware is BFS311 and reports as BFB297 on power up so should be fullycompatible with UV-5R
#7 The GT-3 software has one more menu than the UV-5R for setting freq rangeotherwise it's identical that I see.
#8 The specifications in the manual are identical to the UV-5R.
#9 I'm seeing better FM performance on my UV-5R then the GT-3. Stationscoming in weaker on the GT-3 with both radios using identical Diamond RH771antennas. My experience contradicts Jerry's review.YMMV apparently.
#10 I'm questioning the weather resistance. I don't see a lot of differencefrom the UV-5R. The speaker grill is quite open and you can see the LEDlight through the microphone hole. The keys don't look like they are sealedto the case. I suppose they might've coated the board (haven't taken itapart yet to see)..that would be the only thing I can think of that mightmake it more water resistant than the UV-5R.manual/box says nothing aboutwater resistant.

"It works, with a few small issues. The radio was marked with a decal in the battery compartment as a 2m/440 radio. A call to Radio-Mart told me to check the antenna markings and power up, sure enough the little rubber attenuator is marked 2m/220 and using a charged battery from my 440 unit the display shows 220. When using the latest VIP programming it will allow me to place the 222 freqs in but chirp will not allow it (the chirp is a one month old nightly)
Power on with holding the #3 key says BFB-296. Talked last night on the net with no issues. All the accessories such as the extended battery and car adaptor are also fine. Only distinguishing cosmetic is the front labelling with some reflective type as a dual band If you needed an extra battery for your 2/70 uv-5ra then this is only 35 bucks more for another radio with a 220 band. It was shipped rather quickly also. So far so good."
"Need to get a sma to pl adaptor to check actual power."
"I like the Puxing PX-888K, but the radio is not without flaws. Phase noise is generally low, but the signal is not entirely clean. TX audio is muffled. The jacks for connecting programming cables and headsets can give you trouble later in time. Harmonic suppression is fine though, and the receiver is quite good. RX audio is brilliant – the most beautiful sounding audio to date.
In spite of the price I can still recommend this radio, but using a good speaker/microphone is recommended."Having never used one or even seen it in person, my contribution to the discuss of the PX-888K is: I like the green color. It has cool retro feel to it.

"Dan replied to my inquiry with the following: " It depends on the radio, of course, but if it is going to happen, it would take less than a week of development time. "I didn't see a way to vote/show support for a particular radio on Dan's site. He's doing this for free, so whatever he decides to do next is clearly up to him. As a quick data point, the relative Yahoo Group memberships are:
He didn't venture when that week might occur. And that tiny word "if" looms large.

"There are two components (the DSP and MCU chips) in the UV-5R that determine the band limits.
1. The RDA1846 DSP chip is the chip that generates all the transmit and receive functions and it specifies the band limit as follows.
134 MHz to 174 MHz200 MHz to 260 MHz400 MHz to 500 MHz
This information is provided in the RDA1846 documentation in the file area. Many have reported the UV-5R will operate outside of these band limit on the 134 to 174 and 400 to 500 MHz bands (no one has reported any success using the UV-5R on the 222 MHz band), so my guess is the above band limits are not "hard coded" in the DSP chip, but are just guaranteed band limits and in fact some chips may operate outside these band limits to some degree.
2. The MCU which I believe is a custom version of the EM78P568-44 microprocessor tells the DRA1846 DSP chip what frequency to tune. If the MCU does not send the correct commands to the DSP chip the right frequency will not be received or transmitted. If for example you load in a 222 MHz frequency, the DSP chip is capable of receiving and transmitting on 222 MHz, but only if the MCU provides the correct commands to the DSP chip. If the MCU does not provide the correct commands, the display may should the correct frequency, but the DSP chip is doing nothing. Even if the MCU send the correct commands to the DSP chip, the RF pre-amplifiers and RF amplifiers external to the DSP chip are not designed to operate on the 222 MHz band so even if the DSP chip was commands correctly by the MCU, the power output and receiver sensitivity would likely be very bad."b1gslacker gives the details of how to make the change here. The usual warnings apply - do this at your own risk.
"For those of you who would like to attempt to destroy your brand new shiny UV-5R, here are the instructions for "slightly modifying" CHIRP to accept frequencies WAY outside of the manufacturers recommended operating boundaries. These instructions are for windows XP only (but will probably work for others also)
1) Download the UV5R.pyc file in the files section.2) Using your favourite zip utility (I recommend winrar) open the library.zip file located in your C:\Program Files\CHRIP\ directory (location may slightly differ based on your flavour of windows, but you get the idea).3) Delete the UV5R.pyo file from the zip4) Add the UV5R.pyc file5) Save the modified library.zip
I know that your thinking, but if you don't understand the instructions, you should definitely not be trying this, so don't even ask.
Now that you have installed the "ever so slightly enhanced" version of the UV5R CHIRP module you should be able to program frequencies between 10MHz-999MHz in the CHIRP application.
NOTE: Even if the radio accepts the frequency and displays it on the LCD display, this does not mean that the radio will actually work on that frequency (in fact we do know that there are definitely limits)"
UPDATE 11-12-12: A new version (1.10) has been released under the UV-X4 model. It adds the ability to update the FM Broadcast memories via the software.With the release of the new Baofeng UV-3R Mark II, the original software has also been updated. (You still have the option of using CHIRP.) And, as usual, Julian is ahead of the curve with his post about the updated software.

Support is added in today's build:Via the UV-3R Yahoo Group
http://trac.chirp.danplanet.com/chirp_daily/daily-07262011/
This is a first stab and only represents a couple hours of work, but it
seems to work for me. Feedback is appreciated, although I'd prefer it go
to the chirp_users list if possible. Future fixes and enhancement
announcements go to that list.
Thanks!
