I have K2 #4456 that is generating a tone starting at 14360.66 kHz and
ending at 14365.65 kHz. The tone is adjustable by both AF and RF gain
controls...
Hi Ken,
You'll notice that the birdie in question is well outside the ham band,
which ends at 14350. That was our criteria when selecting what I.F. to
use.
The K2 uses a high dynamic range, single-conversion superhet
architecture with a low I.F. This means that some birdies will appear
somewhere in the HF spectrum -- it is simply unavoidable with
high-level mixed signal sources (VFO and BFO in this case). We could
have used extensive shielding of all subassemblies, but this would have
greatly increased the cost of the radio.
