Ken,
Fantastic.  Very exciting. Thank you for sharing your success and show
casing John's work. What an incentive to get some hardware of my own!
Interesting experience to be able to use a Receiver in Canada and UK at the
same time sometimes seeing the same signals on both.

Minor detail compared to the achievement  - I note that the your receiver's
tuning frequency does not tally with the scale but John's does.

73's

James
