Baofeng UV-50X3 - new mobile radio

Baofeng just launched the UV-50X3 triband mobile radio and it looks like a jab, cross and left hook to the established japanese manufacturers who were caught dreaming about DMR, C4FM, D-STAR and other leprechauns.

Yes, the chinese manufacturers aren't creative, but they are really good at copying stuff and manufacturing it for a fraction of the price, so the resemblance to some japanese models shouldn't surprise you.

Or maybe the Yaesu FTM-350AR ?
Kenwood TM-d710 looks a bit similar, don't you think ?

Red Pitaya Hamlab - HF/6m 10W SDR transceiver and much more

Red Pitaya Hamlab has just been announced at Friedrichshafen Ham Radio 2016 expo. It is a dual-receiver dual-transmitter DDC/DUC HF/6m 10W SDR transceiver with extended measurement capabilities, based on the popular Red Pitaya development board.

The RF is converted to the digital domain with a LTC2145-14 125Msps 14-bit ADC (comparable to what an Icom IC-7300 uses, for example), so performance should be pretty good. Receiver coverage is 0-60MHz and +15dB preamp and -6/12/18dB attenuators are available for different levels of frontend gain settings.

Yaesu FT-891 video

Got the chance to play a bit with the Yaesu FT-891 at Friedrichshafen 2016 Ham Radio expo. The radio is pretty menu-driven, even some of the most important menu options (like ATT or IPO) are hidden behind a few button presses.

The expected price for the FT-891 would be around EUR 600, which is suprisingly low; the way Yaesu looks at it is FT-891 + FC-50 tuner costs around the same as a FT-450D.
