I was going to say, don’t forget to place an alert at https://sotawatch.sota.org.uk/
But I see you’ve already done that (new UTC time 02:00 not 01:00 noted):
I suggest you go back in and edit the entry though - that should be 7.032-CW not a comma while not so important on alerts, it worth making sure when you spot yourself from the summit, that you get that right there as some chasers use programs that look for specific modes and the comma rather than dash might mess that up.
Apart from that, there is a whole list of equipment not to forget. Since you are planning on 40m, the antenna and something to support it, all connecting cables back to the rig, the battery, the morse key, the log book and pen (or smartphone or tablet with logging program). Then there is all the comfort and safety and food and water requirements…
In short there’s lots of possibilities to forget that one 3 cent part that is essential! If you still have time, before you leave take all the gear out in the garden at home, connect it all up and test it and then make sure EVERYTHING goes back into the rucksack.
Good luck, 73 Ed DD5LP.
