Sorry on the other board they were talking about Laser and 729, I was just going to reply but my IP got blocked. And since I wrote it I wanted to post it so here it is. But feel free to trash, it’s so much easier to remember your name and password than get your IP unblocked. Lazy me

The reason for the test may have been the land based and the operational management not singing off the same song sheet. I remember they were supposed to be called Laser 730 and I believe there was promotional material that was produced. Although my imagination could be making this up. But someone pointed out that we don’t have 10 mhz spacing and hence the 729 test.
Suppose you’d really have to ask those that were there. I’m just a well read anorak and a poor memory from wherever I pick this stuff up .
