When Brick wrote about the radio I shrugged. Yet another UV-5R variety? Oh please! I did like the looks though.
However, a recent Baofeng news bulletin says the following about this ‘limited edition’:
Fujian Nanan Baofeng Electronic Co., Ltd, world’s leading provider of high-performance ham transceivers today officially unveils its brand new flagship ‘GT-3’ Two-Way Radio, in cooperation with US-based industrial design partner SainSonic. This is a limited edition that offers an excellent combination of performance, endurance and style.
Utilizing the latest RDA1846S RF IC, GT-3 excels in real-world performance with its enhanced anti-interference capability. In addition, GT-3 provides a new noise-reduction feature for noises caused by severe signal intensity changes and tail tone elimination when transmitting or receiving signals between 50Hz with 55Hz.
Further powered by the state-of-the-art RDA5802N RF Receiver Chip, GT-3 delivers an ideal balance of optimum sound quality with varying reception conditions and low battery consumption.
GT-3 also incorporates the UTC TDA2822L Power Amplifier IC, aiming for the best user experience with a low crossover distortion.
“GT-3 will bring to our customers the ultimate in performance, endurance and reliability, at price points that even the most cost-conscious users will find appealing, not to mention its disruptive exterior design,” said Mr. Alex Wang, CEO of Baofeng Electronic.
The decision to design a revolutionary two-way radio dated back to 2012, when Baofeng was celebrating the one-million sales milestone of its UV-5R series. After 12 months’ efforts together with SainSonic, Baofeng is finally ready to launch the GT-3 into the market, which is expected to create consumer excitement by an industry-leading feature-set.
As a limited edition, only 50 thousands units of GT-3 will be manufactured and be distributed by strictly selected distributors. Initially setting the retail price under $70, Baofeng hopes the GT-3 will be owned by every Baofeng’s loyal hobbyist.
I looked at the original Baofeng UV-5R schematics (download here). Basically the chips have been upgraded to the latest versions. This could result in overall improvements, but I’ll have to wait and see for myself. I might have to hurry, only 50.000 units available!
When you stay tuned to new arrivals on Alibaba.com you occasionally will run into interesting products. The TID TD-M2100 (link) might be one of those (thanks to PA0TBS for the pointer).
The picture shows a Vertex Standard VX-2100, the listing says TD-M2100.
Is it compatible with DMR-2? No. Is it dual band? Probably not, in spite of the suggested frequency range (136-520MHz). Is it dirt cheap? I’ll have to say “Yes”, somewhere between $100 – $120 is not bad for a radio combining analog and some form of digital voice.
Personally I don’t care about the lack of compatibility with other systems. Creating your own network might be just as much fun, and with the average price of a DMR-2 radio in mind you can buy a bunch of these and still keep money in your pocket.
In parts. Literally. Victim of a failed attempt to perform a MARS/CAP mod. Not disassembled properly before heating up the soldering iron, but ripped apart instead.
Initial damage list:
- damaged flat cable connectors (no way to secure the cable anymore),
- various burned parts on the mainboard,
- Burned PCB traces.
Needless to say, the rig is completely dead.
Most of the burned components are here:
The charred capacitors were in stock and easy to replace. FB1001 and FB1002 (SMD-sized ferrite beads) were components I never ran into before, so I had to order these.
Progress so far:
I managed to construct my own system to secure the flatcable into the connectors. It ain’t pretty, but it will be very reliable. After replacing the capacitors I created a few (scary looking but safe) bypasses to check if the radio would wake up. It did. All I can do now is hoping that there’s no other hidden damage.
I still need to complete the reconstruction of a few burned PCB traces where the ferrite beads need to go. The main problem is that the width of these traces is a fraction of the size of the average 0603 SMD component. There is no room for errors, wish me luck. I’ll need it badly.
Relying on sources here and elsewhere, I had a hunch that the base charger could be powered from a 9v battery. I have a 9v attached to a type M barrel connector for an Arduino (another neat bit of kit), so I plugged it into the base unit. The LED went red, as if it had been plugged in to the wallwart. I dropped the UV-5R into the base, and the LED went out, as if under load.
- A 9-volt battery isn’t much of a power house, huh? -
(Seen on the UV-5R group)
Key loggers? Won’t work here, unless you gain physical access to one of my less protected systems, which are basically irrelevant / unimportant test systems. My main systems aren’t that easy; even if you have physical access it will take supercomputers years to figure out how to boot the darned thing.
Don’t forget about my dog if you want to break into my house. He doesn’t bite — he amputates.
