[600MRG] Receiver bandwidth for WSPR

[Brian Pease]

I have found that my WSPR reception seems slightly better using the wide 
3100Hz bandwidth on my HP3586C receiver compared to 400Hz. Have others 
tested this? My theory is that the static bursts reach the sound card 
sharp and crisp without the ringing from the narrow physical filter.  
There should be no effect on the desired signals. The extra noise on 
other audio frequencies may not matter.  Of course it could be related 
to my particular man made noise.................................
