I have an IRL FSK-500 Terminal Unit available. Free to good home - just pay shipping. I have tables reserved at Radio Expo - Boone County Fairgrounds in Belvidere, IL - on September 28 if that would work better. The manual is at Nick's site at: https://www.navy-radio.com/rtty/irl/fsk-500-ocr.pdf 73, Jim, K9JT
