| Both woolly and GPS hats required! |
Today's very brief experiment from a snow-swept Eryri range, was to see how WSPR would get out from a deep valley within the mountains. Due to travel restrictions, I only had time for one transmission cycle to conduct the test, as the main reason for being out was care duties.
I found that, with only intermittent mobile phone signals, getting the Raspberry Pi clock to update via the internet was problematic. To address this, I will need to add a GNSS HAT to it, so that time (and, of course, grid square) can be obtained via a non-mobile phone route. The price of these is quite steep, at about £45.
Quite surprising to see that one cycle of 1W was getting out quite well at 14MHz:
