"Ditto" on your comments, Ken. My modified R75 does quite well for me. I
find it easier to tune and just as sensitive and selective as my hotrodded
Racal RA6790GM. For example, yesterday and today around dawn I had audio on
13 trans-Pacific MW split frequencies, including Japanese, Korean, and
unidentified stations. Hearing these signals between local powerhouses on
the 10-kHz channels takes selective and sensitive receivers with frontends
that have very good close-in IP3 & dynamic range performance. The R-75, when
modded with a few extra parts, is certainly up to the task of foreign
mediumwave from inland locations such as mine. (However, there is a LOT more
foreign MW DX to be heard at a coastal location like the Grayland, WA
DXpedition site.)

Hi Russ:I have removed the attenuator and did the Pete Gianakopoulos'
Advanced MW Attenuator bypass mod and the R75 now shine in the MW band
sensitivity area without using the 2 pre-amps that the R75 have.But
with a good external ant or MW loop like the quantum/justice/kiwa or a
big homebrew MW loop and using the pre-amps you will not have any
problem picking up a lot of far away or weak stations with an stock
R75.An remember that the R75 include a lot of features to help in the
signal intelligibility.The most critical factor in MW dxing is to have
a good antenna and the knowledge of how to use it.I have a K9AY
external MW loop and I recomend it if you have at least a 30 square
feets space in your backyard.For my CCradio plus I use a justice
[Crane co] double coil ferrite ant with very good results...
