I was also under the impression that Avin was USA based.

The avin probably comes from the exact same warehouse as eonon and the rest. Too bad you had to ship it back to China. Luckily for me, eonon does returns in the US (surprisingly).

You're right. I thought it was probably a made-in-China product, but also thought I was dealing with a US-based distributor or rep. Turned out to be an expensive assumption. Even under warranty having to pay close to $90 just to get the radio back to the repair facility sure takes the fun out of things.
