[RTTY] Filtered AFSK transmission

[Joe Subich, W4TV]

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.

73,
