Sold as a Single channel 100MHz Scope for less than $80 with what does come with a few flaws, feebles and bugs, which makes it really a 20MHz workable unit. But it does go to show the Chinese are hot, and going places, where manufactures in the West would never enter a market for such a bargain price.
I did a bit of research afterwards and Banggood sell what appears to be the same model as the Dainu ADS5012H for less than £54 UK!! link here.
One person that always inspires me with his enthusiasm for Real HF Mobile radio, is Dave G4AKC.
Dave often takes off to the front of Blackpool promenade, on either his bike, or his recent electric trike towing a trailer load of equipment behind him, that puts most shack's to shame. His late night shift on the cold sea front, or early mornings well wrapped up, quite often produces some long path and rare DX surprises that you wouldn't get from the home QTH, due to a good signal bounce off the sea water and lower noise being out in the open making reception far easier.
The G4AKC website https://www.g4akc.co.uk/ where you can learn more about his exploits has now been added to my Blog right hand panel "Sites that do it for me links".
Another good Blog link EI7GL for Ireland has also been updated in "My Blog List" link again on the right hand panel.
What could be handy little tool, but it pays to do your homework and research across all selling platforms before you open your wallet.

HF Signals the small company in India headed by VU2ESE, that has recently brought us lots of fun with the BITX40 and the uBITX HF radio kits, has now done it again with the launch of the Antuino.
His headline for the device is A compact Radio Lab for Antennas and Radio circuits.
I would like to think of it as a mini Radio Test Set that can help us understand what is going on up the antenna, as well as being useful tool to help analyse what is happening within the radio or what problems exist within the RF signal it outputs. The plus of course it is hackable, so anyone can join in the fun and improve it with addons or make it's firmware better.
At $99 this is sure going to be another useful instrument to any Amateurs test equipment toolbox.

All the best to you all!
