I live in Bedford.  I hear 680kHz loud and clear, but that is WBEZ.

 

I only have an SDR receiver with a simple wire antenna set up at the moment.  I didn't hear anything on 14.280.

Thanks for all the replies from everyone. I'm not sure if everyone sees the replies through the reflector, but wanted to add some additional info: 

 

I have two rigs, an ANAN 7000 and an IC-7300. Both rigs see the AM signal at 14.280. 

 

I can tell it's WRKO because I switch to the AM band and hear the same dialog on their station. Of course, their station is booming because I'm only a few miles away. 

 

There is no overload condition on the front-ends of either receiver that I can tell. I can reduce the input attenuation and the signal is still there, although reduced somewhat with the attenuation, which is to be expected I think if it's actually interference being picked up by the antenna, as opposed to an RFI path after the front-end. 

 

I have two wire antennas with two separate feedlines, and have the interference on both antenna's.  

 

This just started recently, and can't correlate it to any change I made in my station. 

 

Thanks, 

 

Craig

Good Morning, 

 

Has anybody else noticed interference at 14.280 from the WRKO station broadcasting at 680 KHz? 

 

This seems to have started a few days ago. 

 

I'm pretty sure it's not receiver overload on my end, but actual out-of-band stuff generated by the station (granted that my QTH is very close to the transmitter in Burlington). 

 

I tried calling the station numbers I had available but just get voicemail. 

 

Anybody deal with this before, or have good contact info for the station engineer? 

 

Thanks, 

 

Craig, K1CWD
