Well one point to add to all this. Some time-nuts are hams, some are not. You comment "Used in hamshack" suggests you are a ham. RF interference from your radios will be a problem. It can modulate the EFC and upset things. Granted it will normal up after a while. So do consider a metal box and do use shielded cables. Ground only one end of shield. Might want to consider beads on the rs 232 lines etc. Simply use good amateur radio design/construction techniques. By the way I have a VE2ZAZ system works quite well and for Amateur use is great.
