Alan seems to be having some success with receiving Marco. Up to now 
I have seen nothing from Marco yet when I had a 73kHz/136kHz with 
I5TGC Alan could not see Cesare. But what we are learning is the 
effectiveness of the technique; and the variability of conditions. At 
the we have not been able to correlate the reception of of a distant 
QRP station with the magnetic activity from the sun, if there is an R 
in the month or observations of QRO commercial stations.

So, as Alan implies, the same QRSS techniques used with amateur QRO 
(circa 1w erp) stations could be used to bridge the 'pond' at any 
time provided conditions were reasonable. The obvious solution would 
be to monitor a station running in beacon mode with QRSS keying.
>From our experience this requires a lot of very close liaison with 
the those involved on both sides of the Atlantic and up to now I have 
not seen much evidence of this, although I would be the first to 
agree that absence of evidence is not evidence of absence.

I don't think that you have to mount large 'DXpedition' stations to 
succeed in bridging the pond - patience, liaison and application with 
the equipment and knowhow we already possess should be enough.
