[PCR-1000] PCR-1000 Front end overload

[Martin Francis]

Hi there Dave,

I have a similar issue - I use my PCR to DX NDBs in the 198-520KHz band, 
and without a lowpass filter I get far too much bleedthrough on the lower 
frequencies.

I'd like it if someone could suggest a way of having SEVERAL RC filter 
shunts to kill each of my local offenders rather than attenuate the whole 
band.

Anyone know how to do this?

I live less than 3 air miles from a 50kw AM station (WBT - 1110).  Front 
end overload makes AM band reception useless.  I am using a longwire abt 
30' above ground.  Radio is grounded using the house ground at power meter. 
 Someone once suggested using an RC filter to shunt 1110 to ground, but I'm 
not sure what components to use, etc.  Any help would be appreciated!
TIA,
Dave
