looks like i have another Boeing Test Flight frequency. i was monitoring 11175 and saw a signal pop up on 11306, one of Boeing's HF frequencies. this was interesting because there is currently what looks and sounds like an over the horizon radar very strong over a range of frequencies 11306 was right in the middle of.
the pilot made note of that too and couldn't hear Boeing Everett well through it (nor could i). he said "Can we move to 5451 to see if that ticking sound goes away?" so i moved there and they performed some SELCAL checks. the pilot then asked "what UHF frequency would for you today?" Boeing Everett replied back 230.25 Mhz and they moved there.both were heard loud and clear on 5451 i do not have a UHF antenna otherwise i would have tried to follow them there.
