Could only hear acft on 132.55. UHF ducting only lasted for about 30 mins. Happens every now and then on certain freqs depending on wx conditions.Interesting. Can you hear the VHF side as well on 133.550 or the LDN VOR on 114.300 ? I wonder if it could be a case of ZDC using their backup transmitter ? According to the SOP the backup site is located at "Plains Radar" but it doesn't specify where that is ?
Might be a good day to try some Sporadic E (25-50 MHz) monitoring?
