Do these four tricks apply to a communications-grade receiver on house
mains, such as, say, an older FRG-7?

BM,

Like most suggestions - This is not a perfect suggestion
that works for everyone all the time.

This is simply one of those suggestions that if you try it;
it just may work for you; this time and the next time it
may not do anything or even make things worse.

The main idea is to see 'if' by adding a Ground to the
un-grounded Radio {Grounding the RF Signal Ground
Side of the Radio's internal circuitry}

So starting with a low cost 'portable' AM / FM Shortwave
Radio with a Plastic Case that does not have an External
Antenna Input or an Exposed Ground Connection.

FOUR TRICKS TO TRY FOR BETTER
AM {MEDIUM WAVE} RECEPTION :

1. Touch a Finger Tip to the Tip of the Whip Antenna
- - - Does the Radio's Reception Improve or get Noiser ?
Try this on the AM, FM and Shortwave Bands

2. Touch a Finger Tip to Exposed Ring of Earphone Jack.
- - - Does the Radio's Reception Improve or get Noiser ?
Try this on the AM, FM and Shortwave Bands

3. Take a 15-20 Foot piece of Insulated Wire and strip-off
an Inch of Insulation from one end and attach the Wire to the
Collapsed Whip Antenna. Route the Wire around the Room.
- - - Does the Radio's Reception Improve or get Noiser ?
Try this on the AM, FM and Shortwave Bands

Finally we get to the root of this suggestion . . . # 4

4. Take a 3-6 Foot piece of Insulated Wire and strip-off
an Inch of Insulation from both ends and attach one end
to a ground within the room (Cold Water Pipe?). Make
sure that the Radio's Whip Antenna is fully extended.
Next "Touch" this Wire to the Exposed Ring of the
Radio's Earphone Jack.
- - - Does the Radio's Reception Improve or get Noiser ?
Try this on the AM, FM and Shortwave Bands
HEY - Even try Touching this Ground Wire to the
Radio's Collapsed Whip Antenna )
- - - Does the Radio's Reception Improve or get Noiser ?

"IF" - When you "Touch" the Wire to the Exposed Ring
of the Earphone Jack the Radio's Reception Improves.
Then Modify an 1/8" Mono-Plug to put into the Earphone
Jack to connect a Ground to the Radio for Improved
Reception all the time {most of the time}.
