Fellow hams, I have one of the vs1 speech chips. I purchased three of them about 2 years ago from a local ham n6vg, Jerry. I have installed two of them in Kenwood 2570 and 3530 rigs. They work very well. I think that they were removed from rigs that Jerry had pass through his shack from time to time. I paid him $50.00 a per chip for them. I am willing to part with the remaining one for what I paid for it if you understand that I cannot give it a gurantee other than to refund your money if it does not perform. I purchased all three knowing that someone would be looking someday. Let me know through email if you are interested and I will respond to the first contact. [log in to unmask] Chuck ki6hk
