Luckily I got an email reminder! In the UK, Monday was a public holiday and I feel a day out. Tonight from 8pm UK clock time the 2m activity contest takes place. This is organised by the RSGB and activity levels are usually good.
Normally I manage about an hour or less because of my poor voice. I use 5W and a big-wheel antenna.
UPDATE 2040z: I tried a "wait and pounce" approach, but waited a very long time for my first QSO. In all, 7 QSOs in 5 QTH squares. Best DX was the Peak District.
