June 1965 73 Magazine. Converting the R-508/ARC VHF receiver. High Power with the ART-13 or ATC. Would you believe 500W! Converting the ARC-4 220 Mc Converter from the ARC-27. Now you know what to do with all your spare stock of these goodies. Merry Xmas to all the list members. Without you we wouldn't be here. Larry W0OGH
