Hi Tom. I imagine a loop *could* be subbed if all of the rules are followed. Unfortunately I've never encountered such a case. Plenty of noise here!
I use my 24" external loop even for day-to-day listening of semi-local stations. Is a DX King! And since I use an external tuning cap its infinitely variable for any application.
To sub an ersatz loop into the Philco 60 would require disconnecting the original ant coil (which could be bad anyway) and not only subbing the AA5 loop to correct inductance at the high end of the trimmer range but adding a precise (unknown) amount of capacitance to get it to track.
Not to say it can't work but it hasn't been shown in this or any other random examples.
