Re: [IRCA] 1053 Jammer - who hears what?

[Nick Hall-Patch <nhp@xxxxxxxx>]

Does your recording of the "beehive" jammer have some of the siren 
jammer riding along as well, Chris?

What I've heard here is the basic low grumbling sound with no higher 
frequency components such as on your recording (I don't think high 
frequency components were heard in PEI either).

Part of that may be due to the DXer's tendency to cut off the 
received audio above 2800Hz.    I think I have some SDR files from 
earlier in the season that I can play back with the passband opened 
up a bit more to check.

best wishes,

Nick
