As one of the developers on the FreeDV project, I'm glad more people are playing with it! It is indeed more commonly used on HF as others have mentioned and can get pretty good results depending on band conditions. (For example, I've been able to decode my signal from an Australian based KiwiSDR late at night on 20 meters before. ~50W into a magnetic loop from the Western US, too, which isn't the best kind of antenna out there for sure.) Anyway, if any of the technical issues you found were related to the application itself, definitely reach out and I can work with you to fix those bugs. While the stability has improved since I first started working on it, there's definitely more that can be done.
@@chrissewell1608 FreeDV is basically a digital voice system (similar to DMR or D-Star) but optimized more for use on HF (vs. something like DMR which isn't set up to deal with HF specific propagation characteristics). Unlike a lot of the other digital voice modes out there, FreeDV also isn't subject to patents nor does it require use of any closed-source software. One of the really nice things about FreeDV is that it's extremely spectrally efficient versus, say, SSB. The narrowest FreeDV mode currently available (named 700D) is only 1 KHz wide, for instance, while the others aren't much bigger. This is really good, for instance, if you happen to be somewhere where you have to run a compromised/lower power station as you may not be able to use voice otherwise. I will say that the audio quality is also pretty similar to other digital voice modes as in it's not going to sound as nice as a really strong analog SSB station, but that's something being actively worked on. Especially now that we've gotten funding from ARDC, that will definitely let us put more work into that for sure (among other things). Anyway, hope this helps!

Again, thank you very much for your effort!
Thank you. It's nice to hear that. The amount of times I had to film this due to crashes etc was a little disheartening, so it feels nice to see some feedback in the comments. I'll keep experimenting!
I'm not a ham yet but am a new GMRSr. will study for ham license at some point. have been very curious about Digital and this explains a bit of how it might work. So Thank you for your effort. It has not gone down the tubes for nothing. It does help. Keep up the good work.
This is awesome. I hope the devs are able to make a version for Android devices since it's so convenient to use a phone or small tablet when operating portable using an application like AndFldigi. Gonna have to test this out myself at some point.
...no problem!...i have been looking for ways to go digital on a BTECH UV-5x3 with Digirig and windows 10...much appreciation for what you brought for us to check out! 73!
Regardless of the outcome it was an interesting video. The only thing missing, for beginners, is something about why one might want to even do this. Maybe it's obvious to most, but probably not to new hams. The experimental stuff is very interesting. Keep it coming! 👍
I'm a non-native speaker of English, and I could understand most of the FreeDV-encoded voice samples, even if it sounded a bit weird. I had a bit of difficulties understanding the first callsign, at 13:34. 73 de SQ2KTN :)
Thanks! Yeah decided not to use it because I wanted SOME static for the comparison. But I overshot it, and way over estimated how the baofeng with the rubberduck would operate. Now I know I guess.
I love those DigiRigs. I just wish he would have used jumpers on the pads on the circuit board. My IC-718 needs the attenuator trace cut on it to work well for FT8 and man that was hard to see! Additionally, I had to run small jumper wires to connect a couple pads to convert mine to CI-V for Icom. If it was jumpers it would be easy to change around.... I'll just buy more if I need them. lol
Can you use the K2 cable only? Then wire it straight to the sound card on your computer? Or does it need to the connected with the Digirig, first, just as a radio interface cable?
I asked someone if this was possible, just to use the baofeng as the transceiver and use computer to handle the digital audio signal but everyone told me it wasn't possible as it does something to the audio signal thats fed into the radio. But that being said it's very muffled, like you're trying to talk with a sock in your mouth, or talking into a pillow.
Everyone was wrong. This is how all ham radio digital modes work. Just audio in and out of the radio coded and decoded by a computer. Sounds a lot better on HF though.
@@ModernHam now, would this be able to work say like listening to a D-Star or FM Fusion repeater and sending the audio into a PC to decode, or would the audio output from the Baofeng be too filtered for the PC to decode?
Not really all that bad, the glass, not metallic shielded is opaque to RF and the primary near field is all side lobes. A magnetic mount is a poor capacitive coupling for ground planes, Diamond recommends not using for HF at all. A fender or hatch mount K40 style with a dedicated ground wire is the best of all worlds. Adding a counterpoise of 19" with some silicone probe wire to the antenna barrel of the handheld will make the far field of an HT quite good in those confines. I myself would choose the Signal Stick with the counterpoise adapter.
You know there is no difference right? You are going Dig to Analog then Analog to digital. Still the same FM signal and bandwidth. Where FreeDV really shines is in a bandwidth saving on HF. Nothing is different on FM.. It does obscure the transmission in a legal way if you were in a situation where you were passing sensitive traffic like for ARES. The media listens to us on scanners but they would probably not think to decode FreeDV.
2400B/2400A is designed to be “readability 5” at -132dBm, which is 10dB beyond the point where analog FM stops working. Listening to others who have done field tests, I am able to hear the digital better at range, but I don't have a good ear for static.

Great vid, Free-dv audio is terrible, is there "experimental settings" for tweeking bit rate/codec/etc etc ?
I'm sure you could mess with some of the knobs. I will say HF actually sounds A LOT better.

Can you elaborate a bit about freedv? It encoded your human voice into a bit stream. But how can it send the bis stream on FM analog?
Good work bud... very interesting..73 to you
Glad you liked it!
so you set this up to talk or to listen? i want be able to listen to folks again!
You can do either. You can listen or talk if you'd like.
Can you use the K2 cable only? Then wire it straight to the sound card on your computer?
Or does it need to the connected with the Digirig, first, just as a radio interface cable?
You can use the K2 wire only.
Have you tried the K2 cable wire to an external sound card, then to the PC?
Free! for $90...🤣 Great video, thanks!
You have to solder everytime you use a different radio. On the digirig.
Nah, maybe very specific ones, but I can bounce between the 4 I have just by swapping cables.

Rubber ducky in cars suck (rolling faraday cage more or less)...get an external antenna magmount and it will increase range ALOT
Yeah. I had one, but thought it was overkill. (Wanted a little weak signal to show the difference) I guess I overdid it.
