[hpsdr] [Freetel-codec2] FreeDV always USB or LSB below 10Mhz and USBabove?

[Helmut]

Hi,

it's no sacrilege to use the 'wrong' sideband, if band limits are respected.
On 7 MHz I frequently change the sideband to talk with my friends who run
the Flex 6000 series. The bigger problem is that only a few stations can use
the bit-saving FreeDv mode 700B, which seems a lot more robust and allows
smaller SNRs.

PS: John, I'm waiting and hoping for our first FreeDV QSO as planned before
the UK Brexit make it impossible, hi. Good luck!

Hi All,

The new piHPSDR-Console for ANAN transceivers unfortunatly also has
implemented  FreeDV on all bands in USB. I have allready told them to
change.

Regards 
Gerhard

FreeDV follows the SSB convention as has HF digital voice since day 1.  QRM
avoidance is aided (not necessarily avoided) when both modes are using the
same "sideband."

Flex is now aware of this and I am sure will make the change upon the next
update of FreeDV.

Is FreeDV always USB like all digital modes or does it follow the guideline
of LSB below 10Mhz and USB above?

I use the FlexRadio SmartSDR waveform and have been working under that
assumption that they have implemented it correctly to only use USB. The USB
standard as I understand for digital modes in dependent of SSB guideline of
LSB below 10Mhz and USB above).
