[1000mp] Humm

[Jerry Spring]

I bought a signalink USB device about 2 years ago for Field Day and it works great with my TS-440SAT.  Having the sound card built-in is definitely an advantage and they are less expensive than the Rigblaster Pro.  The tech support at Signalink was also first class as I had a small problem getting it going and the guy walked me through it on the phone.
