[1000mp] On-Air test for Roofing Filter check ??

[n4gi at tampabay.rr.com]

As the INRAD web page says:
"Casual operators would probably not notice any difference in receiver performance."


Tuning through an oscilator signal on an empty band is, well, slightly less demanding than S&P on 20 during CQWW.

Any discouraged folks want to sell me their roofing filter unit so I don't have to wait a month?
