Yet another new rig from China.
HF to UHF (but no 4M :cry:)

The specs seem quite good with 30W HF and 5W V/UHF and with 5 - 32 volt power requirements, could be run from a variety of sources. (output power varies with working voltage).

In my opinion itā€™s layout looks more like a labratory instrument than a rig and getting 32 volts to get the higher output (if ever needed) will be interesting, but if this doesnā€™t turn out to be ā€œvapour-wareā€ it could be an ideal SOTA rig with small size BT connectivity and low weight. Iā€™ll probably hold off buying the new Xiego G90 in favour of this rig if the first published tests are positive.

I note the English article says itā€™s for the Chinese market - I guess that will be until they get the needed European and US certifications.

Addition of 4 metres may just need a firmware upgrade. The same with 60m - at the moment it only covers the WRC15 band.

GPS antenna connectorā€¦ very interestingā€¦ maybe APRS in the box?

From the linked to English article - point 15: 15. GPS time (requires optional GPS module).

So although there is a GPS antenna socket, it seems that you need to buy and extra module and itā€™s to ensure the system time is accurate. No mention is made of any digital data mode support, so I expect it really is just to keep the displayed time on the little screen or via the remote control, bluetooth linked SmartPhone App accurate.

It looks like the lack of a VFO knob is putting a few people off.

no tuning knob; sorry it looks like an ergonomic nightmare to me if it ever actually ships

Well for FM operation on 2m and 70cm you probably donā€™t need a VFO knob but SSB or CW on any band, tuning with the arrow keys could be a problem.

Itā€™s a shame they donā€™t show their Bluetooth smartphone control App in one of the pictures - that may have a VFO like capability (as in PocketRxTx that I use with my Xiegu) which would half get around the lack of a physical tuning knob.

I wonder if any European dealer is planning to show one at HAM RADIO Friedrichshafen at the end of June? (As of yesterday itā€™s still on). https://www.hamradio-friedrichshafen.com/news/2020/ham-radio-on-the-trade-fair-schedule/
