Multigrain artisan loaf, not only can i solder, i can bake.
You really have to be Aussie to understand the phenomenon that is Vegemite, so for those that do, BEHOLD, vegemite and cheese scrolls. To make these are rather simple, make a basic bread dough, roll it out, cover with Vegemite and cheese, roll up, allow to prove and then bake in a hot oven. Then eat the bastards before someone else does LOL
I have the Pi all setup now and its making RF. Next i need to see what I have around here in the way of amplification to get a bit more chooch for my chaach.
The signal is actually pretty clean, the noise you see is from the scope, not the Pi. Crap scope and overly sensitive to noise when its down on the lower power settings.
As you can see by the WSJT waterfall, 15m was going bonkers. Its great to see so much action on there.
The band was open all day and in the evening time, opened into the EU. Cant say I did all that well but I managed to make one contact into the EU and it is my first contact for the new solar cycle, it was with a station in Poland. You can see on the map i was not really being heard all that much in the EU. Probably not quite the sunspot numbers I need for my simple vertical antenna to be reliable enough. But seeing its still only early doors on the new cycle, things are looking promising. I did also spend 15m calling cq on CW, self spotted on the cluster and all and nothing. It was worth a shot.
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.
