Italian efficiency when it comes to coffee should be studied. In Italy: - Walk into a bar and look at the guy - Un caffe - 30 seconds later it’s ready - Shoot it - Leave €1 - Walk out In the US: - Join a line - Wait - Order coffee - Answer 12 questions: Size? Milk? Roast? Sugar? Temperature? Colombia beans? Name? How do you spell it? - $12.34 - Ask for a 20% tip. Click 5 times on a ipad to have a custom tip - Tap phone - ask where to send the invoice - Wait again on a different line - Someone call a name that sounds similar to mine - get the coffee - too hot, can't drink it - finally at temperature taste like shit

Hi @rigexpert, nice tool that I (and my LLM friend) built. It uses rigexpert.com/kits/zero-2/ and ESP8266 to control it over MQTT. #hamradio github.com/s53zo/rigexpert_z… I used D1 Mini but can be ported to other ESPs.

2025 9A/S53ZO/MM South Adriatic family style activation is over. 1067 QSO, 852 unique calls, 65 countries, 6 continents. 67% CW, the rest PHONE (so only human modes). Antenna used was 20m long EFHW wire, TS590S and 100W. The setup performed really well. #hamradio #hamr
