[R-390] R390A Popping

Sat, 27 Sep 2003 21:28:44 -0700

Dear Chuck,

 I also have a R-390A and am hearing a popping sound.  In my case however I
am hearing it on my R8500 as well.  I had to use  the wide Am bandwidth
setting and turn the noise blanker off.  I never heard this popping until I
moved out to California. I have heard this popping at a different QTH in
town so I know it is not local to my house.   The limiter on the R-390A does
eliminate the popping but at the expence of some fidelity.

Best regards
