I read the old post about FreeDV, are people still using it, and what do I need to do these days to try it?

Hey Bill....I tried it back in May when I still had my 6500. The waveform worked ok but wasn't the greatest. I ended up using the Windows freedv client and dax. There were a couple of guys (the same guys) on 20m all the time. That was about it. It worked, but it wasn't a big deal. - Mike, KG9DW

Hello Bill, we in the Netherlands have an active group FreeDV users. Weekly we have a sked on 3630 Khz on Monday, Wednesday and Friday 14:45 UTC for half an our. You can find us on the QSO-Finder: . The Flexradio owners do NOT use the waveform provided by FRS because when transmitting very nasty spikes are produced which at the end can destroy a Mosfet PA. This problem was communicated with FRS, a ticket was made and they confirmed the failure but the issue, dated from October 2016, still is NOT solved. It is an internal timing problem in the Flex6X00 series. So we use the programm FreeDV version 1.2.2 from David Rowe (see ) and we are experimenting with mode 700C instead of the mode 1600.So please take care when you are using the FreeDV waveform from FRS in combination with a Mosfet PA and be aware of the transmit spikes.

I use freeDV as the FRS version only supports USB and the digital voice standard follows the phone system of LSB for 40 and longer. Free DV works well on 630m on ground wave and is within the bandwidth allowed in VK.

I still have it working with the 6300 but have not heard any signals on 20 meters in the last several weeks.
