The RME-69 is a prime example of how not to design a radio if you want good 
performance over its full tuning range. With only one RF stage it still 
needs help above 14 MHz and the sales literature suggested 2 more stages 
from the DB-20 to amplify even more noise and reduce strong signal handling 
ability.
The major reason for the poor performance is almost no padder and trimmer 
adjustments plus rats nest wiring resulting in low gain and a higher noise 
figure than a lot of its competition.

Put it alongside a HRO, NC-100XA, NC-101X, or other contemporary radio.
