Had to cancel my dad visiting today as most of the kids are ill. In some ways I’m relieved as it’s always hard work.
Picked up a second hand Morserino now. Let’s see if I actually do anything with it or it just sits on the shelf like the other SBC based projects… 😅
Had to calibrate my radio yesterday as people reported I was off frequency. You can use a signal generator (don’t have one) or tune into some standard frequency broadcasts. There’s a time broadcast from the USA which is called WWV. They broadcast on 5, 10, 15, 20 and 25 MHz and announce the time. I couldn’t hear any of them when I tried. I think later at night makes it possible to hear it on 5 or 10 MHz. I thought I could hear a carrier signal on 10 and so tried to use that to calibrate the radio - but this just ended up with me being wildly out of calibration!
A friend said as I have two radios I can just transmit into a dummy load and the radio next to it would still receive it. So now I could test easily myself and just adjusted the settings until I was close enough. Seems to work now.
Told another ham friend about it and he had the same issue with his.
