What competition is there for the 817?
KX2? Costs a lot more, does HF RX much better, doesn’t do VHF/UHF.
IC703? Long out of production.
Chinese stuff: Longevity? Build quality? Second hand value?
Altoids radios? Loads of designs to buy as kits or self supply and build. Appeals to different market place.
To my uneducated eye, there’s nothing in direct competition. Noticeable is the provision of NiCD battery and not Lithium. Yaesu want dealers and purchasers to be able to ship this radio in the post without major hassle.
