This transverter was built from a QST project. I have the manual for it. It was used as the backbone of my packet node in SE CT. It can be set up for voice. Unfortunately the crackle paint finish on the top of the was moderately damaged during storage. Selling for $15 AS IS plus $15 for shipping in the lower 48. I can't test it, but it was working when put into storage. Contact me at email@example.com.
