Multigrain artisan loaf, not only can i solder, i can bake.

Beans Beans Beans Beans
Welcome to Dr Sheldon Cooper’s fun with Beans. HAHAHA. As you can see, i have been cooking a bit over the last few days. This is my killer beans recipe with home made sausage. The sauce is tomato based, using home grown tomatos. Plus plenty of spices. Cant wait to dig into this for breakfast.
Vegemite and Cheese
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
Mongolia
I worked a new country today on 15m. Mongolia.
RF Out Of A Raspberry Pi
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.
Pi Hat Ready To go
I have the pi hat built and the filter aligned, its now just a matter of waiting on the heat sink goop to go off so that I can put it together and fire it up and see what it can do.
Last Night On 15m
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.
Amateur Astronomy
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.
15m and The Wall Of Japan
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.
AM Modulation Feeltech FY6600
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.
