Ah yes - memories of seeing two 819 line test cards side by side on a 405 line TV!
Being only about 20 miles from Crystal Palace and Croydon, Sporadic E didn't cause us any problems but when we got the first dual standard sets with a dual standard IF strip, we had great fun if we had one in the workshop.
The first was the Bush TV115L, the end of the TV115 run and its successor, the TV125. No UHF tuners until much closer to the BBC2 launch but ideal for VHF 625 line reception! Anyone familiar with these sets will know that the IF strip is vertical. The bottom two sections of the system switch connected HT and IF input to the relevant tuner so it was a simple matter to stick two screwdriver blades between the appropriate connecting tags to do the conversion which, of course, could easily be reversed instantly if needed!
Reception always seemed to rotate in a clockwise direction. Norway first thing, then moving on to Russia, then to West Germany by late morning. Afternoons were virtually always Spanish TV.
We once had virtually continuous reception from TVE one Saturday afternoon - lots of sport, of course, but not a single trace of a bull fight!
