One possibility is that the rig has only been type approval tested in that configuration, so anyone wanting to operate it with a different filter would require a professional RF spectrum analyzer. Top posted through policy, not belief. Brian Machesney wrote: reflector. The only authoritative

Early versions of the firmware did, in fact, allow transmission through the 2.1kHz filter, and that capability was removed. I suggest that speculation is futile, since there are authoritative sources available. 73, doug Date: Tue, 26 Jan 2010 08:41:18 + From: David Woolley (E.L)

I've searched the archives and found that use of a filter other than 2.7kHz for SSB TX seems to be forbidden. One selects a non-standard filter for ESSB; why can' t this filter be the 2.1kHz or 1.8kHz filter? -- 73 -- Brian -- K1LI __
