20 M has been cleaned up significantly.  40 Meters still has a big
hum problem - I can see as many as five spurs spaced 120 Hz from
presumably 180 to 680 Hz above the (suppressed) carrier.  They're
all -35 to -50 dBc.  The hum was apparent on both the RTTY and PSK31
bulletins tonight - looks very much like an "open ground" on the AF
input.

If you have been listening to W1AW's RTTY bulletins since yesterday
(Thursday), they are now using this version of fldigi.

Oops, that should be the day before yesterday -- Wednesday's Bulletins.
