Re: [Elecraft] K3/K3s; Digital modes, specifically DV
I loaded FreeDV today, on an Ubuntu i5-64bit laptop. It works quite well. I heard no calls on 14.236 MHZ, but the receive function is working. I'm having the usual fun setting up PTT, but it will come along over time. Tried doing the same thing on the Windoze 7-64 box, and Panda AV decided it was a virus and sidetracked it, meaning it IS a virus. That would be the installer program. Has anyone else had this problem? Just curious. I've had other programs trigger Panda to flush them, but nothing like this.

Another fellow about 125 miles away experimented with me on 75 meters during a summer evening in conditions we would not have wanted to operate in otherwise.

Re: [Elecraft] K3/K3s; Digital modes, specifically DV
I'd wait until David VK5DGR gets the FreeDV bit rate lower which will improve the Eb/n0 requirements and bring the performance closer to that of SSB. If you're not already following along on David's blog it's worth a read (http://www.rowetel.com/) his writing style is easy going and he explains things well. His current work on Codec2 700C surpassing MELP 600 in performance along with some new modem ideas will push the limits of what's possible with Digital voice on HF. It will not be long and the performance of FreeDV will be equal too if not surpass SSB on a standard HF channel. Yes this can be done already, however you do end up sounding like donald duck and a bit robotic for my liking on current technology. The work on Codec2 will change this. While the FreeDV code base (Modem + Codec2) is open source the integration work is not insignificant. The current FreeDV codebase in the SM1000 runs on a STM32V405xxx 32-bit ARM core clocked at 168MHz with a real FPU and no RTOS it runs bare metal. That is some serious beans in terms of DSP processing !!! The effort involved in bringing this into any product should not be underestimated, there is still some very serious work to do which results in $$$ spent. While FreeDV is under active development interfacing a linux based laptop to the K3 and using this to keep up with the Jones's is perhaps the best course of action. Those with the K3s are already ahead of those with a stock K3 since they already have the internal USB sound card. However making cables for laptops and PTT cct's isn't hard either. Once the performance of FreeDV surpasses that of standard SSB then would it be time for internal integration work to begin. I'm fingers crossed that the processors and DSP in the next iteration of the K-line will have enough processing beans to "answer the meaning of life the universe and everything" in real time. As David tells me on the local repeater most mornings "MIPS are cheap". That is about the time frame I'd expect both of these technologies to collide. YMMV. 73 Matthew VK5ZM On 28 March 2017 at 04:40, Richard Fjeld wrote: > Greetings to all, > > The K3/K3s is an excellent radio for digital modes due to the ease of > interfacing with a computer if desired.

The mcHF is nice but it is still a work in progress.
But it does show what can be done.

The more I look at the mcHF, the more impressed I become. Once I
get caught up with my current projects I'll seriously consider
getting one.
The FreeDV code and more importantly Codec2 are indeed open
source. I don't know how much room there is in the K3/KX3/KX2
firmware to add something like this but if possible, it would be
quite useful in getting more FreeDV activity going. in the
meantime, I'll make up some cables to connect my KX2 to my SM1000
and give it a try.

Re: [Elecraft] K3/K3s; Digital modes, specifically DV
While the mcHF has some digital audio circuitry, I don't believe it provides a digital voice mode. FreeDV is a very narrow-band (1.1 kHz) digital voice mode using the open-source Codec2, developed by VK5DGR. One can run FreeDV without a computer using the Rowetel SM1000 adapter (https://www.tindie.com/products/edwin/sm1000-freedv-adpapter/). This should work nicely with a KX2 or KX3 for portable FreeDV operation. I haven't tried doing that but it looks fairly straightforward.
