I thought I would dig up some numbers to back up what I have said for years,
the FRG-7 is grossly over rated.
These stats are measured in the lab of the great Ranier Lichte in his
awesome book "radio receiver, chance or choice" the best review book ever
written in the history of shortwave radio. In fact I just modified one of my
copies to make it easy to scan reviews to mail to people for proof of what I
say.

FRG-7 FRG-7700 FRG-8800
SW sens (uV) 2.1 2.1 1.1
3rd order ICP (dBm) -25 -10 +3
selectivity (-6/60) 3.2/8.8 *1 3/7 + 7/18

*1 Wide 11/26 Norm 5.2/13.5 Narr 2.6/8.2

In every category of these most important specs, the FRG-7 loses. In fact
the 3rd order ICP is pretty BAD !!!!!!

The facts speak for themselves, the reputation of the FRG-7 is not based on
reality but fantasy.

I am not crazy about the selectivity of the stock units of any of the FRG's
so my FRG-7 and my FRG-7700 both have mechanical filters and the 7700 has an
upgraded ceramic as well. But the 7 selectivity is way too limited for the
real world !

And the 7700 and 8800 both sound really NICE !!!!
