FreeDV (HF digital voice) for Ubuntu

[Kamal Mostafa]

FreeDV ("HF Digital Voice for Radio Amateurs") -- http://freedv.org/ --
is now available as an installable package for recent versions of
Ubuntu[0].

Many thanks to David Rowe and the rest of the upstream FreeDV team, and
to A. Maitland Bottoms for the Debian package[1].


The freedv package for Ubuntu is available from either of these PPA's:

        Freedv PPA (and its prerequisites) only
        https://launchpad.net/~kamalmostafa/+archive/freedv

FreeDV is a valuable addition of a new & non-proprietary tool for
Hams.

I listened to the recorded QSO and observed two of the three key
operating variables:

1.  Significant saving of spectrum for FreeDV vs analog SSB. (+)

2.  Significant FreeDV artifacts - muffled audio.  (-)

3.  Missing was an on-air comparison of SSB throughput in rough band
	condition and/or weak-signal performance vs FreeDV (The specs
	say "should be readable down to 2 dB S/N" but can you
	demonstrate the difference is real-world practice via another
	recording of a live QSO, please?

	Do you know if anyone has tested this with an Icom IC-7200
or IC-706MK2g?  If so, what have been determined to be the best rig
settings, please?  (That sort of data would be good to gather on your
Web site.)

Thanks for this contribution to our hobby!

I've been using this package on and off since it showed up in a recent
magazine (CQ or QST...something like that). Codec2 was meant iirc to be
a FOSS replacement for the AMBE series which is used in D-STAR and DMR.

It sounds really good.

Really PJU? :-) I should blog about that! :-)
