The DV1 has been around long enough that there is already a wealth of information without having to rehash it all. My short & sweet--- it's a great receiver for
manually tuning the VHF and UHF spectrum. Offers as much digital modes as you can get from a "stock" receiver. It's just ok on shortwave--- the Icom 8600 does a far superior job for me below 25 MHz. If you are a "scanning" enthusiast, this is not as feature-rich as something like the Uniden SDS 200. One should consider the AOR DV1 to be a communication receiver with some added scan/search functionality.
One of the best reviews written is here:
P.S. My AOR DV1 required one warranty repair, which was done at the time at their facility in California. My understanding is that now all repairs go back to Japan--- someone please correct me on this if that's not accurate.
