I picked up one of these units last October.................anyway, I
noticed that the sensitivity wasn't as good as my other units, so I decided
to make some measurements. Across the whole tuning range, the MDS is .3uV,
while with all of my other receivers (7 of them), the MDS is below .1uV.
Is there any failure mechanism that occurs with this receiver? I do have the
schematic set.
