Factory Tour - Injection Molding

Not directly ham radio related, but I suspect the process for creating the cases for the radios is the same. Also, given the amount of effort required to make a mold, you can see why the TYT TH-F8 and Boafeng UV-5R (among others) might look the same.

MIT Media Lab IAP 2013 - Shenzhen, China:
"The tool and die shop was amazing. I had no idea how massive the tooling was just to make a simple enclosure. The tooling is cut out of steel using CNC, EDM (Electron Discharge Machining), and manual milling. Each steel mold can weigh a ton or more and requires a lot of manual and automated work. Depending on the finish, the molds also need to be hand polished. To tool and die shop consists of a lot of heavy metalworking equipment. The steel blocks are first cut on the CNC machine. The EDM machine is used to remove steel in parts that can't be cut accurately using a CNC machine. It uses electrical current to remove steel at a rate of 5 microns per electrical burst."
And on a side note, the drinking matches my experience, too. The hosts would, one-by-one, engage you in a "ganbei". This might result in your having four or five drinks to their one. You could often respond with "cheers" and you would just have to take a small drink instead of finishing your glass. Another tactic would be to tap the table with your drink and it meant everyone at the table had to "ganbei."
"This concluded our tour of this injection molding factory and the boss of the factory took us all out to lunch. I didn't realize that lunch included drinking alcohol and we had many "ganbei" (chinese for "bottoms up") glasses of beer with the boss. By the end of lunch, I was fairly trashed and Bunnie was getting there too."
Oh and the "white lightening," as we called it, was horrible. I much prefer the warm Coca Cola and ginger drink that they also encountered. I've actually made that drink at home a few times.
"AQS, a contract manufacturer that was helping to organize all the tours and also a company that Bunnie works closely with, took us all out to dinner with their staff. It was a wonderful dinner and we talked about a lot of the things we saw with them. They also broke out the Chinese hard liquor (53% alcohol) and proudly proclaimed that they wanted to drink with us. I hid from the "white liquor" since I've had a few bad experiences with it but most of the others were game to try it out. Overall, it was a fun evening with AQS and it was our first real dinner together as a group. It was a wonderful chance to meet everyone and hear about what they were working on, why they were on the trip, and just randomly ramble on in a happy, semi drunken state :) "

Chinese Radio Reference

I'm losing track. I'm gonna build a reference list. I'm not sure of the format, but I thought I would link to the manufacturer's website, maybe get pricing, link to my posts about that radio, and then any notes about what made that radio special. Maybe a list like this...

Kight Radio $109.95
409 Shop $105.00

Chinese Radio Mega List by Nate - Part 2 - HTs

Here is the second part of Nate's e-mail with the information about the HTs. (Most of this is from his e-mail, but I've edited it so assume any errors are mine.) Part I was about mobile radios.

Baojie BJ-UV88

BAOJIE have an HT model: BAOJIE BJ-UV88


HYS have an HT as well: HYS TC-UV11 and HYS TC-UV99 (if you need a larger flashlight). And the HYS TC-UV88 that looks a little bit like the Baofeng UV-5R / TYT TH-F8.

More UV-5R clones / brands:
ZasTone ZT-V8 ($85.50 on AliExpress)
Mstar M-UV1 ($56 on AliExpress)

Mstar M-UV2
Mstar also has the M-UV2 (Totally different radio)

Baofeng UV-5R: Ronson UV-8R

So, we have the Baofeng UV-5R, the Waccom UV-5R, the original TYT TH-F8, and now the Ronson UV-8R that looks like the other radios, but claims to be a7W dual-band HT. I don't see the radio on the site yet so no price or other details..

Baofeng UV-5R: TYT Spare Batteries

Hans compares the TYT TH-F8 and Baofeng UV-5R batteries. The batteries appear to be the same except for a slight weight difference and some cosmetic molding. And despite the different rated capacities, he suspects they may be identical internally. He's going to do some more looking, but if that is true then the TYT battery is a much better deal at $4 less than the Baofeng. Looks like the Baofeng brand is beginning to be worth something.

Chinese Radios - The Center?

The Baofeng UV-3R is a re-branded Vero Telecom UV-3R.

The Vero Telecom VR-2200 is a re-branded TYT TH-9000.

The Baofeng UV-5R (which I cannot find on the Baofeng site) is similar to the TYT TH-F8.

When the UV-3R came out, I thought VeroTelecom was going to be the actual manufacturer - if not the design house, too. The UV-3R was availible as a Baofeng UV-3R, Magiksun UV-3RComtex UV-3R, and a Zastone ZT-UV3R. Vero Telecom was going to be the source.

Now it appears that the VR-2200 is actually a TYT TH-9000. And the UV-5R looks like it has it origins in the TYT TH-F8.

Is TYT going to be the center of the ham radio world for China manufacturers?

Does ICOM buy Yaesu radios and re-brand them? Is Elecraft reselling Ten-Tec rigs? The game is different in China. Maybe they just like to keep us on our toes. I am going to need a map.

Baofeng UV-5R: Schematics

Via, a direct link to a PDF Schematic of the UV-5R. It is interesting that the file name is F8UV-1846 (bottom right in the drawing). I wonder if the F8 is for the TYT TH-F8 and the UV is for the UV-5R. Just some idle speculation on my part.

Baofeng UV-5R: Waccom UV-5R 5W

Steve points out that the 409Shop has a Waccom UV-5R for sale. The description says the unit is 5W. We've seen the other versions of the UV-3R (Magiksun, Comtex, Zastone), but the specs were normally the same. I still want to know if the UV-5R is a Baofeng product or if they are just re-branding some's hardware like they did with VeroTelecom and the UV-3R. Clearly, it is similar to the TYT TH-F8.

Baofeng UV-5R: Dual Band?

If this picture is accurate, then the UV-5R is a dual-bander instead of a single band radio like the TYT TH-F8.

Also, a hat tip to Nate who pointed out the OH6HGN web page.

Baofeng UV-5R: New Baofeng Model

Chris (NH7QH) at Hawaii Radio Sales sent me the following about the new Baofeng UV-5R. (On a side note, Chris is now also selling ham equipment via eBay.)
"Just got this email - looks like it is a TYT TH-F8 - same marks and all mono band, already FCC approved since a TYT."
He also included a couple of pictures - see below. The styling looks more like the UV-3R +. Other obvious features are the charging connectors on the battery pack (so a drop in charger) and the keypad. I am not as familiar with the TYT radios, but it looks like Baofeng is willing to leverage the success of the UV-3R to build its brand by buying radios from multiple companies (Vero Telecom and now TYT). This model also more directly competes with the Wouxun. (I felt like the UV-3R was more of niche radio than a direct replacement for the Wouxun's.) These Chinese radios are keeping it interesting for sure. Maybe Baofeng needs to rebrand a mobile and steal the thunder from the much anticipated KG-UV920R.
