dl-fldigi built on Linux.

[Dave B]

Hi.

Well, after a long wait, now I've upgraded and standardised the shack
PC's to Mint 19.1 64 bit.  So, I set to, to build dl-fldigi, knowing
that others had done a fair bit of work to update it for current
'nixes.   Many thanks to them of course...

Using the instructions at :-
https://ukhas.org.uk/projects:dl-fldigi:build-ubuntu#building_on_ubuntu_1804

Sadly, the instructions using  git://github.com/ukhas/dl-fldigi.git 
Fail, with an unmet dependency relating to ssl libs.

However, scrubbing that, and trying with those that use  
https://github.com/philcrump/dl-fldigi.git   and it's related
instructions, works very well as they also load the needed ssl dev libs,
that the previous instructions fail to do (or assume that the users
machine already has them.)   But build it did.

I managed that on this laptop, and via a ssh link to home, on another
machine.    Lots of compilation warnings, but no errors on either case.

Launching it, on this laptop seems fine, but on the home machine, RTTY
mode seems to have pinned the incoming audio indicator to full, but no
signal is present (I know that, because the radio is off!) or shown on
the waterfall, it also complains about a Pulse Audio error.  The link
home was unstable anyway due to others saturating out bandwidth, so I
just bailed out and will investigate more later.

On the laptop in front of me, I get background noises and sensible
incoming signal indication.   So, as above, I'll see what the shack PC
does when sitting in front of it later.

Anyway, is the "philcrump" version the recommended up-to-date issue, to
use with habhub these days?   "Help About" just reports the base Fldigi
version, no mention of the habhub/ukhas revision/version or whatever.

I can't at this time remotely power up any radios, so will have to await
the weekend to test it all for real, hopefully, so long as I don't get
tasked with doing something else.

Question.  At some point (way) in the future!  I will have AZ/EL
steerable beams.   Is there any way to get the needed antenna pointing
data out of dl-fldigi (once it has acquired the payload) in any format
for use with an antenna tracking control system?

Comments welcome?

Regards to All.

sensible replies!)

dl-fldigi has a pipe on which the decoded characters are sent  - you can
read the pipe decode the strings and then with a bit of simple math
calculate the Az/El

Hi.

The odd behaviour of the Received level indicator/squelch control, more
or less vanishes when there is actual audio from a radio.

Next step I guess is to wait for a HAB to attempt to track with this
build, on the main shack PC.
