2021-05-03: Two aircraft inbound to Penticton, BC (CYYF) were not heard on the mandatory frequency (MF) 118.5 MHz during their initial call-up. On closer inspection, it was found that calls were received from both aircraft, while the aircraft were receiving broken transmissions from the Penticton (YYF) flight service station.
