I made some CW qso’s in the past on 2 meter, but very rare. There is so much empty space on 2 meter. A big noisy silence, there should be more CW activity there. I think that most of the VHF/UHF hams are not being able to work CW. My problem is I didn't have a horizontal polarized antenna for 2 meter. Only a vertical for FM use. But when there is a great opening, even with a vertical I could make CW contacts.
Yesterday I worked RU9MJ on 12 m with PSK31 with 5 watt. On 17 m I worked YU150TC and LZ60RCP with CW 5 W. On 20 m I worked RV3KJ with 5 watt SSB, he was 59 here with 300 watts, and I got also a 59 with 5 watts, so he was very surprised that I had such a nice signal with QRP.
This morning I was working CW QRP with 1 watt on 40 meter. I worked F5SYC/QRP Phil he was running 3 watts - and G4EHT Bill (see photo) from Lichfield, UK.
