Good fun on the 145 Alive 2m FM activity event yesterday. The map shows all the stations I worked (my QTH is the blue dot). Best DX was 95 miles. Pretty happy with that running 5W into a 3 ele Arrow 4.5m above ground. (QTH 100m ASL)

Made a nice satellite QSO via TEVEL-4 with Sergei (ES4RM) in Estonia using my FT70+Diamond RH770 whip antenna.

Yesterday, I set out on my first wx balloon/radio sonde hunt. Unfortunately it landed in the sea as is often the case for balloons that come my way. Still, it proved my tracker receiver and phone app were working but I need to put an external antenna on the car to make it more usable.

I worked the Greencube (IO-117) satellite today for the first time.

I managed to made 6 QSOs which was way better than I expected for a first attempt

Of those six, 4 were first time QSOs and I got 5 new grid squares and 2 new DXCC entities πŸ˜€

A few days ago, I resurrected my TinyGS LoRa satellite groundstation (https://tinygs.com/station/M5JFS@1596546728).

Using a modest 1/4Ξ» ground plane antenna temporarily mounted outside a conservatory window about 6 feet off the ground and facing west, I've been getting some good results.

Looking forward to getting the antenna mounted higher soon.
