Hi,

I mostly do MW listenign/dx'ing. I would be interested in feedback
on how well the R75 performs on MW. I know there are Kiwa mods to
increase the MW sensitivity. Are these really necessary? Is the
difference that dramatic?

Well anyway, I would be interested in any user input on the R75.

Thank you

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...

The K9AY is a good antenna. Is your antenna amplified? How is it
configured? Do you have two or four loops?
