A new, colorful dual-band HT popped up on my radar screen: the Quansheng TG-620. Prices vary from around $50 (Walkie-Talkie Shop) to around $60 (AliExpress). Prices do not include shipping & handling. I never heard of the Walkie-Talkie Shop before, don’t know if they’re any good. They do accept CC and PayPal though.
According to the specs there’s a 144/245 MHz version too. 245 MHz? Where is that used?

Hi Hans.
More about Quansheng radios:
http://www.brickolore.com/2013/03/quansheng-electronics.html
According to this:
http://en.wikipedia.org/wiki/Personal_radio_service#Thailand
Thailand has 80 channels between 245.000 and 245.9875 MHz, 5 watts, unlicensed CB like use.
Nate.
Thanks. Somehow I missed that list from Brick.
When I wrote that list back in 03/2013, they were just advertised,
no one was selling them yet.
BTW, just spotted the Quansheng TG-R20 (the one made to look like a cute small animal) on kightradio.com, with an image showing it in 12!! different colors!! – unlike the usual Black, Blue, Red, Yellow and Green.
Nate.
$50 ???
Could these be UV5R and UV5RAX in disguise?
Curious minds want to know…

i seriously doubt that. Quansheng radios always have been different and unique in design, and I’ve never seen them pop up under other names.
On the other hand, with Chinese radios you never know.
245MHz is used in Thailand as CB. Regular CB is not permited. Since is not really regulated, 245MHz radios are used by pretty much everyone (security, shopping malls, etc) and also on the countryside. They are known to some as “RED RADIOS” and 245MHz is the “RED RADIO BAND”. Most radios come pre programmed with 80 channels and the legal Tx power limit is 5w. I believe the red color is mandatory, or, at least, a standard amog different radio brands. They are avaliable as both HT and mobile transcievers, some mobiles go up to 10w Tx power but I am not sure if that is legal, the same goes to “freeband” (no default channels) and “scrambler” radios. Amateur 2m is also heavily used, know as the ICOM BAND.
