The R-2000 is the only KW receiver that I've never owned. I know these old Kenwood and ICOM receivers had deliberate attenuation below 2 MHz. I did a Google search for a mod to remove it and this is what I got from their AI:
"AI Overview
The Kenwood R-2000 receiver has a sensitivity of less than 2 µV for SSB/CW and less than 20 µV for AM in the frequency range of 150 kHz to 2 MHz.
The official sensitivity specifications (for 10 dB S+N/N) are as follows:
SSB/CW: Less than 2 µV
AM: Less than 20 µV
It is worth noting that some users have found that the sensitivity on the low frequency bands (below 160m/1.8 MHz) can potentially be improved by changing an internal link setting from the default 'Local' to 'DX', though this requires opening the unit. A good outdoor antenna and proper grounding are also recommended for optimal performance on these frequencies."
Local/DX internal link? Do they mean a wire to cut or a switch? I know that the R-1000 required removing resistors. Has anyone done a mod to bring up the LW/MW sensitivity?
