Eventually there will be a 600 meter Amateur band, so covering 495kc to 510kc would be a nice feature for the K3. It would be the first commercial radio to cover 600 meters then. If there was a way to add a option kit for the K2 to do this, I would be #1 on the list to buy it...hi hi... 73 Mike WE0H WD2XSH/16 on 600m
