Indeed. For his background musing er music something
small like SDRSharp used to be is your tool. Call it maybe
DABSharp. Fire it up in the background, probably on the cheapest
NUC he can get. Hm, I have a collection of junkers around here
(former theme park ride vehicle audio playback devices). Some of
them still boot. So what if they are XP machines? I did say "old"
sdrsharp, didn't I?

only 8km away ?? then you do not need a big antenna like your
lopper (but seems to be a good wideband solution)
a paperclip poked in an rtl dongle should work (for your local
for dab"dx" you need a good vhf yagi for around 200 megs but
you sure know that
... while talking about antennas ... is your feed mounted ?!?

Probably I’ll develop as a plug-in as I have the radio
interface available. Once working I could then make it a
standalone program but that’s quite a lot of work.
One reason for DAB+ is I then have the classes
available for future work, also I can listen to Jazz FM
(UK) and also play DAB+ when we get good Tropo.
Currently using a nice 100 to 600MHz log periodic, am
only ~8 km from the transmitter.
could you include that in console?? or will it be an extra
app like qt dab?!?

QT-DAB does work, drives the Airspy
correctly. My birthday present from me to me in October
will be my own DAB+ receiver app 😊
look for qt dab ... soft from jan
lots of hardware included (rtl dongle, sdrplay, lime,
pluto etc etc) ... he even works on receive via dab and
retransmit on analog fm stereo (if you use a pluto) ...
then you can receive your favourite dab station on any
normal fm radio in your house (retransmitting not finished
jan is now on holiday but will be back in a few weeks
(mid of july?!?)

haven’t built it or even looked at the code.

It depends. If it is built to use FFTW, then yes. The
CPU-load in my case is around 17%.
But if I build Welle-IO
using Kiss-FFT and
compiled using fast-calls
the CPU drops to only
Edit: the Airspy problem
is proably related to how Welle-IO
handles SoapySDR. Not
very good IMHO.
