@g7soz @m1geo @m0taz Belgium has summits! Admittedly several of them have car parks at the summit, but it's quite nice to be mostly activating in woodland.

Dark and dingey outside? Mosquitoes biting? Must be time to make and test a new antenna! 😁 All set for some 30m SOTA QSOs #hamr #hamradio

After a week+ of SOTA (various pics over at @m0vfc/" target="_blank" rel="nofollow noopener">mastodon.radio/@m0vfc/), tomorrow it's @rsgbiota time! I'm hoping to be active on 20/30/40m CW from Rathlin Island, EU-122. Only on foot, so I'm afraid QRP, but should be on air somewhere around 1000 to 1400 UTC as MI0VFC #hamr

@rdavies6 @M0KVI @QRPerDotCom @PicoAPRS If you do not transmit RF, you do not need a license - there is no transmitter to be licensed. If you do transmit RF, and wish to do so while the transmitter is unattended, then you require an NoV.

@alexbloor If you're keeping return water temperature below the dew point of the exhaust gas, you recover the latent heat of condensation, which isn't insubstantial. I think on a condensing boiler, 70C Vs 40C return is something like a 70->90% efficiency change - worth having ..

*** I should just add that #1 and #2 might conceivably save energy. But, a tiny amount. In certain rare circumstances they could potentially, I think, also case you to use a fraction more energy. Basically it's not going to be a game changer, energy consumption-wise.

Common misconceptions about energy saving. 1) "If you turn down your boiler's flow temperature, it will save energy". But, if you don't alter your thermostat, the system will still be aiming for a given room temperature. Meaning sure it will run lower, but it'll run for longer.

Still watching to see what happens on this platform, but my callsign (M0VFC) on the Radio instance of The Other Place is me. (If the policy changes, I'll post actual link) As verification, this phrase is posted earlier from that account than here: neither-needle-noise-upon
