Hi Brad,
Just some random ideas... What you are trying to do is very doable. Ive
seen a lot of people do it for VLF reception... Usually along with some
kind of FET amplifier before the mic...
The frequency xlating FIR filter doesn't have great performance on the rbpi
at the moment.
The frequency
As an avid fan of Raspberry Pi, often putting them to use for DSP
applications, I just want to say thank you for your hard work keeping
gnuradio working and optimized on the platform!
I've seen some great FET preamp circuits available on the internet, a few
of which I've tried out. I'll dust one o
Thanks for the support!
Regarding your VLF experiments there's an historically interesting VLF
transmitter Grimeton SAQ sometimes active on 17.2kHz.

Hi all,
I am honored to be accepted by GSoC and GNU Radio. I could not do this without
the support of community members and mentors.
I will continue to work with the community and try my best to bring the Verilog
simulation feature into GNU Radio. I will report my progress weekly on the

Hi Moses -
And just to confirm, if you remove your LDPC block from that flowgraph or
replace it with a passthrough, you don't see the leak?
Cheers,

An official gnuradio raspberry pi image or PPA would be really neat!
Raspbian comes with an older version of gnuradio not properly optimized.

My understanding Raspbina was bult for the orginal armv6 Pi. The 3 is
aarch64 which is far more interesti
Yeah I think raspbian is built to run on all versions of the raspberry pi
so it's 32 bit and no neon...
I'm running Ubuntu server now built for aarch64 and especially the
improvements in NEON makes it very attractive for SDR indeed..

There is some magic involved in shrinking a RPi image so that it will
then expand when reinstalled, like the original Raspbian. I went
through the pain a while ago and documented it here:
