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 ?!?

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.
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.
using a nice 100 to 600MHz log periodic, am only ~8 km from
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 yet)
jan is now on holiday but will be back in a few weeks (mid

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
-Gr), then the
CPU drops to only 10%.
Edit: the Airspy problem
is proably related to how Welle-IO
handles SoapySDR. Not very
