Yu's upcoming rig in its prototype case

6-80 meters, 50 watts SSB/CW, 20 watts on digital modes.

No projected release date or price yet.

Images of Yu holding it give a better perspective of the radio's small size than if it were simply on a tabletop.

  1. John, do you know if the new BG2FX radio will have a built-in soundcard where we can run audio and control via a single cable? A pretty cool SOTA/POTA radio!

    1. Yu is mostly posting just photos for now but said that more details will be coming "soon". There looks to be two USB-C ports on the case.

  2. Hey John, hope you’re well. I’m very interested in seeing Yu’s latest project - it’s fascinating to see the development of a tiny 50W transceiver, but I doubt I’ll be ordering one. I suspect the price will be quite ‘choppy’ once you’ve paid carriage and import duties, etc.

    I’ve got the latest (Mk3) FX-4CR and 20W is more than adequate for me, since I only ever use the radio when outdoors in great locations. No doubt I’ll WANT one when it goes on sale, but I don’t think I’ll actually push the BUY button.

    1. Hi Tom, I'll "want" one too, no doubt, but I've already decided that I'll sell something if I decide to buy it. No out-of-pocket for this one and I'll wait at least a few months for reviews to hit the 'net before deciding. At least that's my story for now!

  3. I'm guessing this radio is just an upgraded FX-4CR, so it will have an integrated sound interface and Bluetooth. I still find Yu's firmware to be poor. F5BUD's firmware is light years ahead. I'll only be interested in this new radio if it is supported by F5BUD. And I likely won't buy from the first batch. Yu has a history of undocumented changes during the life cycle - which is frustrating. Having said all that, Yu has made some pretty good hardware and I love my FX-4CR with V2 firmware.

    1. Hi Dave - just an hour ago, Yu made the following comment on FB:

      "Testing the new firmware shows a significant performance improvement in CW mode. FM mode reception has also been improved. If you are familiar with CW mode, please email me and help me test it out and find more improvements. Thank you."

      He's trying and I'm hoping for good CW performance. Maybe he's working with F5BUD...?
