@geerlingguy Jeff, should I wait for the #HackRF Pro? Currently tempted to buy my first HackRF One and a #PortapackH4M. But the more I dig into it the more I read/hear that the HackRF One isn’t really that good. 😳 Many issues fixed and optimized in the HackRF Pro. But how long will it take until a #Portapack for the HackRF Pro will be ready? – Maybe a short video with your thoughts? #HackRFOne #HackRFPro

@Moosader Do it. Renewal is cheap and you won’t need to retake the test. Point to point communication will be useful, even if you cannot legally encrypt it. Familiarize yourself with SDR, in particular the #HackRFOne made by @GreatScottGadgets

OK, I did my double-slit experiment using narrow-band #FM transmission on the 23 cm #HamRadio band using a #HackRFOne and an RTL #SDR. Raw data looks inconclusive, but I'll have to plot it to see what's going on. I hope I can see at least a little interference pattern. If not, I'll try the anechoic chamber to check under ideal conditions.

I finally built the screen for my double slit experiment. Time to fire up that trusty #HackRFOne #SDR. If my math is right, at 23cm wavelength we should see a separation of the interference fringes of 1.15 m at a distance of 1 m behind the screen. I just hope edge diffraction and multipath is not going to totally kill it. Will find out hopefully tomorrow. If it works, it'll be a nice assignment for my students. If not, I'll have to stick to boring old lasers.

Curious to know what people’s favorite uses of the #hackrfone and #FlipperZero have been so far

@kylewritescode Hang in there, my friend.

As for me, I’ll try to do the double slit experiment on the 23 cm #HamRadio band using an old Covid barrier wrapped in aluminum foil. The idea is to demonstrate interference, edge diffraction, and multi path propagation to my students. No idea whether this will work in our lab/classrooom with the el cheapo RTL #SDR receivers and the #HackRFOne I have. I shall #FAFO.

Monitoring 10m today using the HackRF while noodling over that antennae software, I heard a thin voice calling out his callsign, not all of which I could make out.

“CQ, CQ, CQ” he called, followed by his callsign, only the first four letters I could make out “0N6R—‘

“Seeking any station with an interest in exchanging signal quality reports”, he kept saying.

I’ve happened on many an established sideband conversation under way, which feels more like eavesdropping a telephone conversation than doing radio - this was the first time I ever heard that Ham in the distance, transmitting that request for contact.

I really felt bad I didn’t have a proper transmitter operating so I could properly respond to his call.

This is basically what I’m attempting to do with the hackrfone. I do not have the enclosure this fellow has. Mine is built into a custom ham radio cyberdeck dealio built around a raspberry pi4.

https://youtu.be/0OvrzxlSv90

I think I’m probably about to drop the change for a Usdx Usdr HF Qrp SDR Transceiver, 8 bands, all modes, around 140$ on the amazon.

Yes it does SSB. Also SDR means I should be able to configure it up with gnu radio companion.

#gnuradio #amateur #radio #hackrfone #sdr

I just got my first receiver working with gnu radio companion.

Nothing fancy, mind you - an osmocom source, a slider for center frequency that doesn't do what I expected at all, a waterfall, an AM demodulator, and an audio sink.

I thought I'd tune it by adjusting the center frequency but it's not the case.

It does show the expected spectra on the waterfall though, and there is radio noise and static playing back over the speakers.

I can't tune it, but it does make radio noise! Hey, it's a start :D

Fun RX on the 10m band with the #hackrfone and CubicSDR.

Mostly truckers, and some guy in southern Cali reminiscing about an old job at Northrup Grumman in the Satellite division.

Cool Stuff. 10m is rarely active for me here at EL29kl.

#amateur #radio #hamradio

So I got this other flow graph put together that is built for a slightly different (simpler) SDR, which I chopped out of the flowgraph and dropped in the osmocom for the hackrf in it’s place.

I’ve got all my filter taps in place, per the diagram.

Problem is, those taps refer to each other by name, and some of those are abbreviated by grc using the elipsis…so I’m having to work out which ones are what. I’ve also found a decimal point off by one in one of the variables and corrected that.

I still have some red lines here and there, but I’ve got a complete system on the grid now that I’m debugging instead of a parts of things I’ve seen that don’t work with bits missing and whatnot.

I still suspect that some of my blocks need upgrading or patching or something, but for now I’m moving forward and see how it goes.

So this morning when I started, I was pretty sure I had everything I needed to support the HackRFOne and went merrily off to follow the tutorials until I am become The Wizard.

Yeah, sure-sure.

Of course, thats not how any of this works.

The HackRFOne tuts were stale, and there's still a good deal of confusion here and there; the wide band fm reciever block, for instantce, provides an interface for de-emphasis tau, but the code generated for the block has no idea wtf that is even about.

So I found some stuff that didn't depend so heavily on on such special-purpose blocks, and build up a proper FM receiver based on a lot of other fundamental blocks and relevant block connection paradigms involving virtual sinks, fast fourier transforms and the typical like -- and I'm hopeful. I've yet to add some proper defaults to some bandpass filter taps.

I may sneak up on it, if I decide the whiskey wont interfere.

I'll keep ya posted.

So I've noticed that gqrx seemingly drops an incredible amount of the sample, did someone set the sample rate too damned high?

I know that CubicSDR seems not to have this trouble, but it does have other less annoying issues.

@rombat @kelvin0mql

You are quite correct, except that spark-gap CW is verboten. Othere than that, it's all pretty much wide open, as you say.

Another important directive to the Ham from the FCC is "never use more power than is required to transmit a clear signal".

Just for the record, I have in fact made a foxhole receiver or two, and tuned in a local AM news radio propagandacast.

So today I’m continuing to extend my capabilities with my raspi4/hackrf build.

My first pass today was to follow the suggested path through the hackrf video tutorials. These are extensive, and there is a few hours, maybe more of these, and its a shame that they are out of date, focusing on an older version of grc, which incorporates a mess of wxwidgets blocks that are no longer preferred (QT is currently the rage).

These will no doubt still be incredibly useful at a later date, when I have gotten some traction with some slightly more general material.

I’ve already found some more generic instructions elsewhere, will note in replies concerning anything I find that’s useful.

My current project is to see if I can get my Great Scott Gadgets Hack RF One to do some WSPR stuff in the 10m and up band(s).

I have a dipole antennae I made in my attic out of 70 ohm coax; it was measured for those frequencies.

I put a NanoVNA on the antenna the other afternoon, down here on the end of the cable where the RaspPi/HackRF connects, and measured about 2.4 at 10m, and down about 1.2 at 70cm.

It isn't perfect, but I think everything should be fine at 5w and under.

come at me bros

Any #radio enthusiasts want to suggest a good #SDR for someone looking to move up from cheap RTL-SDR dongles to something that transmits?

I'd like to learn more about modern digital RF, particularly cellular and spread-spectrum waveforms… so initially I started looking at the #LimeSDR and #BladeRF type units. (The #HackRFOne is neat, but can't do full duplex…)

What about the ADALM-PLUTO (and clones), though? It's cheaper and seems to be a favorite of the #AMSAT folks.

A favourite part of my job is that I get to give Great Scott Gadgets hardware to people and groups that are actively working on contributing to their community. I spend hours every month sorting through applications to pick one that will make a difference to research, accessibility, and making events happen.

Most of the applications I have received aren't incredibly inspiring. The current applications lack a descriptive motivation, don't elaborate on how a device that is received will be used, and they lack flair.

I know many of you are creative, thoughtful, and well-connected people. If you want free Great Scott Gadgets hardware fill out the free stuff form below, or if you know someone who would be a good applicant please share it with them. Help me make a bigger impact with this program. https://greatscottgadgets.com/freestuff/
