[RFI] Help with noise

Wow .. how close are those to your station?

Do you have any attenuators you can place in 
line with your HT in AM mode (so as to 'get out' 
of any possible saturation in the AGC loop) and 
try DFing again?

If the HT is AGCing on that noise, and you're 
trying to DF it, a change of 10 dB in signal 
strength might only be barely detectable in
the 'sound' coming out of the speaker *if*
the noise is strong enough to engage the 
AGC to the tune of 20 or 30 dB.
