A friend of mine Simon, who is also a ham, send me this image he has taken today of the sun, clearly showing 2 sun spots. Pretty damn cool if you ask me that a home gamer can take these kinds of imaged with a telescope in his back yard in suburbia.
5pm local time and Japan is running hot on 15m. I have not seen this many signals on 15m in god knows how long. I am even working some of them. My plan was to come in here and solder up a filter for the Pi board and here I am making contacts. Japan might be easy DX from Australia, but they are plentiful and that makes it fun.
I needed an AM modulated signal for something I am dicking about with. Selecting the AM wave type with a 7Mhz carrier produced a 50Mhz singal. I am not sure what is going on there, but I think it might be the DAC aliasing. So after RTFM and coming to the conclusion it was as good as toilet paper, IE something to wipe your arse with, I did the old Jazz hands routine and searched on google for the answer.
The answer was actually quite simple, set channel 2 to the modulation width you would like, in this case i think I went 20Khz, set channel one to the carrier frequency and the hit the modulation button, select the modulation type and Bob is your uncle.
This is the 20Khz signal 100% modulated.
And this is the view on the spectrum analyzer, it kind of sorta looks like an AM signal yeah? I probably should have reduced the carrier power level and increased the modulated signal level to make it look more legit, but hey, i was excited enough to get this far and was over the whole fix it till its broken work cycle that I employ. Anyway, I now know what I am doing, and probably need another signal source to try demodulating AM signals, something to use as the LO as I am tying up both outputs on the function gen.
Onwards and upwards.
