Hearing 6M Beacon at 16.6032
I have an interesting case to report.

I am receiving a beacon on the KiwiSDR, iding as K1MS. It's actual transmit frequency is 50.063 MHz. Both the beacon op and I confirmed with a separate receiver (he a PROIII, me a IC-706) that this is not a real signal but more a case of intermod.
My setup is a delta loop antenna down to a PolyPhaser arrestor at the building entry, then an Array Solutions AS-RXFEP receiver protector, then into a shielded enclosure with an additional Mini-Circuits SLP-70+ low-pass filter on Kiwi antenna port. Lambda linear supply. All in a barn with little else.
Looking at the simple sum and difference, its either 33.460 or 66.666 MHz.
Thoughts?

The LPF was from the previous SDR, selected to attenuate the FM BCB but leave HF with as little attenuation as possible.
I'll get back out and check on the beacon signal level. I don't have a LPF right at that cutoff but in light of this I think I'll get one.
I've purchased a low-pass with a more appropriate cutoff.
Thanks folks!
