Hi Dave,

I got back on the air late last year after a 5 year period of station building.   The major change that I noticed was that no matter
where I operated (except for 10 meters) , I was QRMed by unattended Winlink stations.   So whatever busy frequency detector is being
used, it's not working.  

>>>That's because they aren't using busy frequency detectors, not because the ones they're using don't work.

>>>The busy frequency detectors incorporated in WinMor and ALE are actually quite effective. If such busy frequency detectors were
retrofitted into Winlink servers, there'd be a significant reduction in the QRM they generate. Sadly, attempts to make this happen
have been rejected.

>>>With respect to RM-11708, my recommendation to the FCC and to the ARRL is that no unattended station be allowed to use a
bandwidth greater than 2200 hertz within the 97.221(b) subbands unless equipped with both CW identification and busy frequency
detection capability. That would incentivize unattended stations seeking higher performance to incorporate busy frequency detectors.

>>>Independently of RM-11708, I believe that all unattended stations operating outside the 97.221(b) subbands should be required to
incorporate both CW identification and busy frequency detection. Accomplishing this would require FCC action.

         73,
