[1000mp] MP Roofing Filter from INRAD

[John]

Turn off the DSP ......

It hiss like a snake. Actually almost all the annoying noise in the MP is in the 455
IF section...and specifically in the 455 notch circuit. I have bypassed the Manual
notch in my MP and it is quiet as a mouse...... of coarse I lost the manual IF
notch...but I use the DSP one anyways. I like to run my MP in the analog mode at
times and the hiss was just unbearable to me on the higher bands. Now the radio is a
pleasure to use.....
