[1000mp] Data fiters

[Jim Smith]

I'm working on eliminating the 500/250 problem from within WriteLog.  
SM6CNN has used Macro Express to automate the process I outlined in a 
separate post on the 500/250 in AFSK/PKT/RTTY topic.  I only had a brief 
time to try it before NAQP RTTY and ran into problems.  I believe that 
the problem is localized to the area between the fingers and the chair.  
During NAQP I grudgingly manipulated Menu 5-4 to switch filters and 
found that, while not a truly desireable solution, it was way better 
than not having one or the other filters.

At the start of the contest I dialed up Menu 5-4 and set it to 8.2 with 
the Main VFO knob.  This selects the 250 Hz filter (I have just one, the 
8.2).  When I wanted the 500 I hit Fast Enter, turned the Main VFO knob 
to select 500H (didn't have to reselect menu 5-4, the rig remembers the 
last menu selection until it is powered off) and then hit Enter.  To 
complete the filter selection I then hit Nar1 followed by Nar2.

Not great but better than nothing.  The fact that I don't have to 
reselect Menu 5-4 is a big help.  When I get the automated solution 
working I'll announce it.
