Fuji Abound
I must confess to being a little flippant, I didn't think it did & I saw the report by Boeing. Though I too used to make sure it was off, & have lately become lax, & the radio seems to have got worse lately.
Pure coincidence.
Ground based stations may be a possibility, 119.*** freqs seem to be more of a problem?
I have no other radio nav kit other than a PDA memory map GPS.
