LF/MF
Like I have said many times
before. QRS speeds of 3 or 10 are usually sufficient and maybe
30 in extreme cases but speeds of 120, 240 and slower are not
useful because of QSB and QRM hits breaking up the trace and
producing misleading results.
in fact even faster CW is useful
for an ID under poor or bad fading conditions.
Use as much power as possible and
a good elevated antenna to overcome path fading and qrm. QRP
signals are vy prone to QSB whereas the QRO signals make it to
DX destinations.
Grabbers running at vy slow
speeds are not useful
