One interesting signal source to play with is WWVB. You will have
to "tweak" the W3FF dipole for the selected freq. It is a stable
(given atmospherics) and strong source. See which one does better.
I did a quick WWVB (10 MHz) test with the MP-1 and the B&W AP-10A
It's a tiny nit to pick, but you mean WWV at 5, 10, 15 and maybe 20MHz, and
WWVH in Hawaii on similar frequencies.
WWVL is the VLF emitter at 60KHz
WWVB is defunct
IF I recall correctly
