I recently picked up one of these interfaces for my Icom 756 Pro as seen on eBay.
I saw G4ZLP sells these on eBay for a very reasonable price of $8.99
It came in a couple of weeks in the mail. No insert or manual at all, just the cable.
I am happy to report this product works flawlessly with my Icom radio and software from HRD, Ham Radio Deluxe. Don’t hesitate to buy one of these for your radio!
