Hello radio friends ..
I want to announce my negative experiences that no one is wasting his time with the Signalink USB.
Connected to the Signalink with the original data cable on the Ft8900.
Result after 2 days and endless attempts to let the Echolink run with the FT 8900 at Win 10 64 Bit no chance. The money for the Signalink can be saved and with about 5 Euro self-made something better to build that works immediately.
Very disappointing what the product Signalink USB with Echolink delivers
