[IRCA] WKDN 950 Philadelphia harmonics

[Aaron Kreider <aaron@xxxxxxxxxxxxxxxxxx>]

Should I be able to hear harmonics of local Philadelphia WKDN 950 during 
the day?

I live 3.5 miles from the station.  I'm in the path of their directional 
beam.  They use 43 kw.

I wrote the station engineer and he said they were following the law.   
I can hear them on the 2, 3, 4, and 5 harmonics using my Wellbrook 
1530S+ (active version - less amplification) and QS1R. They also mix in 
with 900 khz and a local RFI noise (probably a switching power supply).

Their strongest signal (950 khz) is only -13 dbm (loop pointed at the 
station).  On 1900 khz they are -75 dbm.  On 2850 khz they are -71 dbm.  
I cannot null the harmonics.

My antenna is 10 feet from power lines (unfortunately there are power 
lines all over my property), so they are possibly being radiated by that.

Can anyone else near Philadelphia hear them?
