San Francisco centre KSFA I receive almost daily on 8867MHz from Sydney Australia. Signal 5/9 is the normal. Commercial aircraft’s leaving Sydney’s International Airport and departing to Los Angeles KLAS airport or San Francisco airport first communicate with Sydney departures 123.000MHz. Then there transferred to Brisbane VHF centre and then transferred to San Francisco Centre KSFA HF 8867MHz. At thi point I loose the signal because it’s VHF.
