Thanks @WRTC928 this is good information to know. I too am interested in a radio with all the controls in the mic. I tried the QYT KT-9900 which, I think, is basically the same as the Anysecu WP9900. Meh.... It was okay, but I ended up returning it, in favor of searching for something with a better build quality and duty cycle. Some of those mini radios seem like an overpowered HT on a bigger heat sink. Still, when I keyed up for more than about 15 seconds the fan kicked on in a desperate attempt to keep it cool. It was not thermally stable. Also, the QYT was ham locked and if possible, I'd like to find an open/unlocked dual band unit with mic controls.
I will be interested to hear your impression of the Abbree AR-7600 after you have had it and used it for a while longer.
Thanks again!
