Is the receiver modified? *Is the preselector effective?

NO modifications.
I use an outboard antenna tuner a "Gilfer BCL Antenna Coupler Model
Q5".
On my FRG-7 which is marked as a SEARS COMMUNICATION RECEIVER, (Yeasu
just put SEARS marking and a "Death Star logo on a stock FRG-7), the
internal preselector is rather broad.
