[1000mp] Another kind of mod

[Pete Smith]

According to INRAD, there is a default active low pass filter in both RX 
chains of the MP when the DSP is off.  On some radios, the main RX is flat 
to about 1.5 Khz, while the sub-RX peaks around 700 Hz and has considerably 
lower response above 1000 Hz.  They say adding one .047 uF cap to the main 
RX LPF can cut high-frequency hiss by 10-15 dB, and include the cap as a 
"bonus" with their IF mod.

I'm wondering if anyone has installed this mod and what you think of it?  I 
note from Inrad's instructions that they say some MPs have the same values 
in both LPFs already, while others have a different value for C3015.  They 
don't say whether Mark 5s all use the same values and therefore have the 
same LPF response.
