Re: LF: QRS SPEED

Mal,

If you read the posts you will see this QSO has been very well documented here on this group.

Om

Can you please produce evidence of your JA qso.

I would like to see the Argo shots of your QSO ie Callsigns in both directions and reports exchanged.

I can supply evidence of my DX QSO'S TA and normal CW QSO'S with Russian stations.

I and others await this information

What do you know... Answer, nothing useful to this discussion.

You have no experience using long dot lengths or paths outside the small confines of EU on LF where it's easy to preach your BS as it only works because of the density of stations...

Also your preaching about much power and huge vertical antennas is not relevant.  Once you reach a certain point say the 1W ERP limit we are all equal. So the only multipliers left is integration and operator practice using long integration technologies.

Alas, this is what burns you up as you have no skill in these areas and when you try you end up working the neighbour's toaster oven as your comical attempt to copy Stefan on 9KHz demonstrated...

It's too bad you're the type of dog that can't be taught new tricks...

So rather than waste BW on the reflector spend some time TRYING to work some real DX at say the 12000km or 7100km range and then post some meaningful comments.  You'll find that your worn bag of tricks won't work.

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
