Build a movable rack from 3" x 3" aluminium angle mounted on castors, about 2' x 2' x 5' on which I can mount ARC-5 Tx and Rx, plus modulator and 28v power supply, plus speaker & switching. ARC-5 racks & shock mounts and modulators are as scarce as hen's dentures in NZ, so I doubt I'll make much progress. Would make a nice display though. 73 de Neil ZL1ANM
