LynnGUEST
It's also expanded in some other radio control apps.
LynnGUEST
The new Ether SDR supports MIDI, so it burns in that.
LynnGUEST
Before we
MarvinHOST
get in too far, let's just see if we can get a little bit of the Ham Radio Today stuff in here, which will kind of, I think, lead us into our next segment of some changes and things that's happened.
8 MINS LATER
LynnGUEST
Smart SDR for Windows doesn't support MIDI control.
LynnGUEST
Raimu SDR and some of the other newer ones, SDR, Oxide, and I can't remember the other ones that are coming out there.
LynnGUEST
I've heard of them, but Ether SDR is probably one of the most popular apps right now for radio control.
MarvinHOST
Yes, it's a very good program.
Pedro ReyesHOST
So we've got USB host here, so it could be for microphone or for keyboard.
Pedro ReyesHOST
What is it? SDR, STI, the radio communications.
Pedro ReyesHOST
Up teasers of that.
Noel RuizHOST
And
ForrestGUEST
So I put up a, and by the way, it holds my club call K7BKG.
ForrestGUEST
I put up a two meter RBN node and I really love the question and I would be very excited to talk about it, but it took me about like 48 hours to fry my SDR from my kilowatt beam on my roof.
ForrestGUEST
Rest in peace, the tiny filter, by
AraHOST
the way.
AraHOST
we designed it for
ForrestGUEST
that.
ForrestGUEST
I actually believe, and somebody could push back on this in the comments, it's extremely easy to damage a 2-meter SDR if you have HF... within the vicinity.
ForrestGUEST
Yeah.
Lloyd Van HornHOST
Thanks to really good Pacific Northwest conditions last Sunday night, I heard 1320 CHMB in Vancouver, British Columbia, and 1600 KVRI in Blaine, Washington.
Lloyd Van HornHOST
Both matched the Kiwi SDRs out west.
Lloyd Van HornHOST
Those are two which I had on my watch list earlier in the evening on Sunday.
Lloyd Van HornHOST
Also heard 1550 KQNM in Albuquerque, New Mexico, shortly before they dropped off at sunset.
TimHOST
Next up is web workflow display stuff, which is what I am working on this morning so far.
TimHOST
and i have this running here which is working on the esp version of this so uh to to set the stage a little bit i would it looks like it just finished which is nice um to set the stage a little bit while i've been capturing all of these uh photos from the iss and doing all these other ham radio projects actually have another learning guide in the works that's unrelated to ISS stuff but is still in radio land with an SDR while I've been working on all this SDR radio stuff I've realized that it's like the antennas really want to be outside to work the best especially for things like the SSTV pictures and stuff like that So the antenna wants to be outside.
TimHOST
The fruit jam needs to be with it because the antenna needs to plug into the SDR.
TimHOST
The cables aren't super duper long.
TimHOST
I can do a thing where I sort of like run the cable outside and keep the fruit jam inside and that sort of works as well.
Michael BurchHOST
Now to the space 2.0, where we're seeing, as you said, the COTS, the commercial off the shelf components changing.
Michael BurchHOST
You know, you got FPGAs, and now we have software-defined radios or SDRs, and that allows, you know, a user like myself to be able to actually orient and, you know, be able to track a satellite and get the downlink depending on a number of factors.
Michael BurchHOST
But to have that be at the user's control technology-wise is a really great place to be.
Michael BurchHOST
And as you were saying, like, these are new problems and a new domain, and it's That innovation is really the drive that brought me in and kind of following in your footsteps there.

Expressing gains in PID controllers through mathematical notation In this paper, we analyze the mathematical representations of PID controller gains used to tune the algorithm.
Steve O'BrienHOST
that can listen to any frequency that, well, I don't know.
Steve O'BrienHOST
Depends what the SDR is capable of listening to.
Steve O'BrienHOST
And once you have whatever channel you're trying to get, there's, of course, physical limitations and this and that, and technical limitations, software.
Steve O'BrienHOST
But you can do it.
TimHOST
So last week the SSTV receiver guide came out.
TimHOST
So this is now published, all about receiving SSTV photos using a USB SDR device and then various different antennas.
TimHOST
A lot of this guide ended up being centered around receiving photos from ham radio, amateur radio folks.
TimHOST
But the real thing that sent me down this path was actually more so the ISS, the AR ISS, Amateur Radio ISS program.
TimHOST
They do SSTV events a couple of times a year.
TimHOST
As it turns out, there was one a couple of weeks back.
TimHOST
And so at the start of that is really, the start of that last event, Series 33 Student Education, that is when I started getting into this and I real quickly got the Fruit Gym and the SDR set up to be able to try to catch some of these photos from it.
TimHOST
So for anyone who doesn't know exactly what is going on here, I will back up just a moment.
Zach MillerGUEST
So I'm one of the things I feel like, especially from my last job we learned is that some of the really cool RF stuff that happens in the world right now is treated like black magic because it can do some really cool things.
Zach MillerGUEST
Sure.
Zach MillerGUEST
And so I'm playing with SDRs in my home lab, trying to experiment with that.
Zach MillerGUEST
I think that's maybe a good place for me to stop.
Aaron CrowHOST
No, those are all awesome things.
