I have 2 portable (handheld scanners, a Radio Shack Pro 79 and a ICOM-R5) scanners and have connected to the comptuer sound card with no problem, except for mono sound rather than stereo which is no issue to me. I just need to purchase a audio line-in cable which you can find in many stores for $1 (Canadian) which is used to connect to the line-in input of your sound card. That's it.
I don't understand why they said radio scanners are not compatible with computer sound cards.
