[Elecraft] Possible misfeature, K3 RTTY DTF

[Doug Faunt N6TQS +1-510-655-8604]

I find if I turn the RTTY dual-tone filter on when the width is wider
then 400 Hz and then off, the bandwidth doesn't return to what it was
before the use of the DTF, but is left at the narrow bandwidth
appropriate to the DTF.  It seems to me that it'd be correct to revert
to the previous width setting.  

Also, turning on the DTF doesn't switch roofing filters, either.

Am I missing something?
