John, this and the recent contacts with G3OLB are of interest to me, given
their range, as I've no doubt that Ofcom will want some feedback on what we
are achieving in terms of range.  We have as you know in mind to try and see
if they will allow us a little more ERP  (but don't hold your breath!).

I'm sorry, but I've been away a lot and often too busy when I'm at home to
check past e-mails, so it would be helpful to me if you could convert the
power levels below into ERP for me (you refer to your normal power providing
an aerial current that would provide an estimated 100mW ERP from your
aerial, but I'm not sure what TX power this is so can't scale the figures
below).

I'd be interested to know as well the estimated ERP for the G3OLB contact,
the nominal RX bandwidth and some indication of how easy the signal was to
copy (I presume that it was conventional CW).
