I used to use a Kenwood R-1000 modified with 1.9 & 2.9 Collins IF filters
switchable in narrow. It was used with a Radio West 15" long ferrite loop. When
I used this combo in Golden Valley, MN, back on in the '80s, I had no noise. I
had Australia on both 702 & 738 at once, definitely in // & got the ID of sorts
clearly "this is ABC".
The sensitivity of the R-1000 was rated at 35uv on MW. The IC-7200 is rated at
13uv on MW & LW (10dB attenuator) & the 10dB preamp works down to 250 kHz. Even
below 250 kHz QST thought it good. A technical type says when you reduce DSP IF
bandwidth, the sensitivity improves. I guess I may never be able to take
advantage of full sensitivity of receiver with so many noise sources. How many
of you have S-0 noise? Some of us may wish to become your neighbors. 73, George

It would be good to know if the IC-7200 has a built-in high pass filter as
many of the previous ICOM models do (e.g., IC-746 Pro, IC-R75, etc.). For
the best MW DXing (esp. with weaker TP/DU signals) these attenuators need
to be removed or bypassed to make the sensitivity competitive. With the
surface mount construction so common now, this is not an easy task.
For domestic MW DXers though, the IC-7200 could be fine out-of-the-box.
