[evla-sw-discuss] Feed heaters

[Bryan Butler]

i thought at one point that rich was going to put this control onto the F317 
operator's screen (the equivalent of 1 + 2 below)?

rich can correct me if wrong, but my recollection is of seeing a diagram that 
bob hayward gave rich, which had the feed heater info (and ability to control) 
on it.
