Dear Dick,
It depends what sort of operation you are going
for - most random 2-way QSOs take place between about 137.650 and 137.750kHz
at a speed of 3s/dot. At this speed, a few Hz drift is not a serious problem,
and VFOs are quite practical, provided you monitor the frequency. The easiest
way to do that is to watch your TX frequency on the RX spectrogram display -
that way it is easy to see if your QRG is drifting across someone else's
signal. At most QTHs there are fixed-frequency spectral lines visible in the
display which make convenient calibration markers when you get to know them.
Most operation seems to take place after dark and before midnight, but it is
not unusual to see QRSS during the day.
For the transatlantic or other long-distance
beacon-type operations, longer dot lengths are needed, usually 30s or more,
with consequently better stability. The choice of frequency varies according
to prevailing activity - at the moment, the trend is for non-european stations
to use frequencies around 137.78kHz, while the Europeans use around 135.92, to
avoid causing blocking to nearby stations - but this varies between individual
operations. For transatlantic beacons, propagation normally starts to open up
about 2300 or so, and to fade out when it gets light, about
0800utc.
Good luck - not sure if I will be QRV today or
not, but will try to be tomorrow evening, so might see you then.

As I am new to QRSS I have some questions:
1. What
frequency to be used.
2. What speed to be used.
3. At what times
transmission to be started and finished.
Hello Dick
If I see or hear your signals during my visits to the
shack I will let you know. If you QAP on 7025 khz +/-
QRM when you are active I will work you xband if I see your
signals. I do not spend much time in the shack, this is a hit and miss
operation but you never know hi
