Alinco R8T HF Receiver on the Bench



Right now I'm up in the shack looking at the faceplate of the new Alinco R8T HF receiver. This has been a very interesting radio to test so far and may be a very worthy candidate if you are looking for a desktop shortwave radio. I will be working up a review of this radio shortly for the pages of Monitoring Times magazine in our First Look column.

You can get more information on this radio at http://www.alinco.com/Products/DX-R8/
