REPEATER MAINTENANCE LOG
1976

This is a transcript of the Repeater Maintenance Log for the year 1976.
The only editorial changes made during the transcription is that
I've added VE to the callsigns which in most cases were logged
as 3xxx since at the time only VE3 calls were issued.
Comments in RED added during transcription for clarification
