The 949 is an antenna tuner. To make it accessible, you will need an external swr meter that is accessible. This could be a meter such as the LDG PW1, or a meter adapted with an audible circuit which would decrease the pitch of a tone as the swr became lower. Manuals in pdf format are on the mfj website. Other than the drawings, they usually read pretty well with Adobi. K5XU
