OK; just checked out the Service Manual for the 'President George'. Looks interesting. Never seen or heard that one before. But I suspect that since BOTH of those radios are ultimately made by Uniden (IIRC) they should both be formidable.
I would use one as a base; the other as a mobile. Trade positions for each radio from base to mobile. Re-test, compare, and let us know.
