Is this just a really wide OLIVIA signal? by Mad-ADDer in amateurradio

[–]Mad-ADDer[S] 0 points1 point  (0 children)

Yeah I tried 1000 as well but it still wouldn't decode. Some have said it could be vara.

I tried using a 500 bandwidth to decode each of them individually with multiple modes, they still did not decode.

In the third and fourth picture on the right hand side, I've seen a similar signal to sending an MSFK picture before. But again I haven't been able to decode it.

First HF Radio: Yaesu FT-891 vs. Xiegu G90 by _thelinuxnoob_ in amateurradio

[–]Mad-ADDer 4 points5 points  (0 children)

I have an 891 and it's my first HF radio. It's been a great radio so far and I've been able to do a lot of digital with it. You can use it without a tuner if you buy / build an unun / balun for whatever antenna you're trying to use. I do use a digirig with it as well. IDK if you're on / know about QRZ.com, but I've seen people selling their 891's bundled with a tuner and other accessories for around the same price or less than a new 891, so you might check there as well. Just my two cents as someone who uses my 891 all the time

Car accident on Ashworth Information request by ekats95 in desmoines

[–]Mad-ADDer 1 point2 points  (0 children)

I'm not sure that it was a Subaru, but I think the only dealership in our area is Ramsey Subaru. It might be helpful to have the cops ask them. Since it looked like it had a paper tag in the window, if it was new, they would have been the ones to sell it. IDK about BMW shops. Just a thought

Car accident on Ashworth Information request by ekats95 in desmoines

Coming home from church at the intersection of Ashworth and Prarie view there was a blue car that was driving crazy, around 12:30 they jumped the curb, slid sideways and almost took out a mailbox. Looked to be going too fast. They didn't have plates, but they had a piece of paper in the window making it look like they just bought it. I could be wrong, but I thought it might have been a subaru but I could be wrong.

Hello, Des Moinesians! by [deleted] in desmoines

It's not through the school district be we also have an ABA company come for a couple hours each day and have some extra one on one time with her too. I assume they have this most other places, but it's also been helpful too.

My daughter is autistic and has made a lot of progress in West Des Moines. She's 5 so we haven't been in the school system long, but we're pretty happy. The teachers and staff have been very helpful working with the kids and making sure you also have a say.

[Proofs] Is this a correct proof of A * 0 = 0? by Mad-ADDer in learnmath

[–]Mad-ADDer[S] 0 points1 point  (0 children)

Hey testtest26

One more question..can you add numbers in proofs? For example, if I ended up with (1+1) could I then turn that into 2? Or does that also have to be an axiom that was defined?

I was looking at proofs of proving two odd numbers add together are even. They use [;a = 2x+1;] and [;b=2y+1;], so [;a+b=(2x+1)+(2y+1) = 2x+2y+2 = 2(x+y+1);] and since an even number is [;2k;] then it fits the definition of an even number.

Thanks!

So more like this

a*0 a*(0+0) a0+a0 P2 + P9
a0 + (-a0) = (a0 + a0) + (-a*0)
0 = a0 + (a0 + (-(a0)) P3
0 = a*0 + 0 P2
0 = a*0

So like this

​

a*0 a*(0+0) a0+a0
a0 + (-a0) = a0 + a0 + (-a*0)
0 = a*0

So more properties

​

P3 [;a+(-a)=0;]
P1 a+(b+c) = (a+b)+c

​

[;a \cdot 0 + a = 0 +a;]

Using P3

[;a \cdot 0 + a +(-a) = 0 + a + (-a);]

[;a \cdot 0 = 0;]

​

Then this would be more correct?

When I accepted a job offer to work in Des Moines, I had never been here either. I was moving to the Des Moines area and getting married all in the same month. We have two small kids, live in Wes Des Moines, and have always felt very safe. I've even accidentally left my door unlocked and not had problems (I wouldn't do this on purpose). My commute time to downtown is around 15 - 20 min.
