17.7 dB transfer loss from RF IN to IF OUT is why...
But isn't that just an engineering design decision made by the
Elecraft team? Since that decision was (hopefully) made with regard
to the entire radio system, isn't that decision likely to be a good one?
As one data point, my K3 is not modified, yet the IF panadaptor works
extremely well, and PowerSDR gives peak heights approximating the
true signal strengths seen at the input of the K3. When I feed in a 1
uV signal from my KG-2 signal generator, I see a definite distinct
peak on the panadaptor, and when I feed in a 50 uV (S9) signal, I see
a large S9 signal on the panadaptor.
I am a loss to understand why you guys are quarreling with the
Elecraft design in this instance. I am beginning to suspect that it
is simply because it does not agree with the usual designs provided
by some military contractors who are probably using an _arbitrary_
"standard" anyway.
I would think twice before possibly damaging my radio or lowering its
resale value with non-factory authorized modifications.
YMMV.
