Re: [IRCA] Sorry, some of my carriers were local noise

[Nick Hall-Patch <nhp@xxxxxxxx>]

If it's any consolation, George, I had a similar experience with the 
receiver itself doing the dirty work.  Some years ago I was working 
in San Diego and staying very close to the ocean.  A friend in the 
city loaned me a Cubic receiver, very high end, figuring I might hear 
DU's from my location using my little active antenna.   First 
morning, I heard tons of 9 kHz carriers, and went off to work 
figuring that audio would only be a matter of time.   Practically no 
carriers were heard on my own receiver, a Dymek DR333, but hey, the 
Cubic was high end, and was obviously proving itself.    Each 
morning, lots of carriers on the Cubic, no audio, until one day I 
came back to the hotel midday for something, and figured that I'd 
spin the dials to see how this sensitive receiver heard daytime 
DX.   Um, carriers every 9 kHz; none on the DR333 though.   Ouch.

best wishes,

Nick
