I have an (original) RIGblaster radio-to-computer sound-card interface for sale cheap. I bought it in late 2000 and as I remember I hooked it up once to see if PSK31 was for me. Problem was, it was, and I quickly graduated as time went by to bigger/better units. So here it sits, and it's shack clean-up time. Old tech, but it works. Jumper-adaptable to most rigs.
Perhaps you want a spare for one you use now?
With 300ma wall wart, original software CD, no cables. 4-pin mic in and RJ-45 mic out chassis connectors. Full documentation included.
Paid $99.90 for it in Sept 2000. Yours for $25 + shipping.
