Last year, I used this tiny antenna on many HF bands.
It is only about 50cm across and sits on the shack windowsill, but worked remarkably well on FT8.
I must try it again on bands like 17m.
At the moment I am on 10m FT8 RX. Plenty coming through.
UPDATE 1710z: 500 stations spotted on 10m FT8 RX today.
UPDATE 1926z: 603 stations spotted. Stragglers are North and South
Americans mainly. QRT soon.

Oscar 100 activity
Every few weeks I take a peek at activity on the geosynchronous satellite
Oscar 100. Activity levels are similar to the last time I looked: not high
and still plenty of space.
