|Reports from the first transmission|
I was curious what the current drain would be as that is important for powering it with solar energy. I have a DC amp clamp meter which shows roughly 500mA when transmitting with 1W. A little high I think, should measure it with another multimeter. On standby it should be 34mA. At the end of the day I decided to switch it off. I was reported by 44 unique calls and best DX was VK5MR at 15690km. I ordered a 78L10 voltage regulator so I hope to connect the WSPR TX directly to a 12V supply like a solar powered battery. Not shure about the housing. And I probabely need to use a low pass filter to supress the harmonics. Anyway, that are worries for later. The WSPR TX kit works and that was one of the goals of this project.
