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?
