For Sale: bladeRF x115 with GPIO expansion

GNU Radio
1

I just don’t use it much since I primarily use 2m amateur band. Very
clean and little use; never left my lab bench. The x115 is the large
FPGA version. Also included is the GPIO expander board and the 1m USB
3.0 cable. Works great with GNU Radio via gr-osmosdr.

Asking $600 via PayPal with USPS Priority Mail shipping in USA.

Yes, thanks, I’m aware of that. I already have an N210 + WBX +
LFTX/LFRX cards so that’s getting all the use. I have been doing allot
of LF DX monitoring recently, so 60 kHz isn’t even low enough.

Thanks,

BladeRF have released an transverter that extends the frequency range
down
to 60KHz. Are you sure you want to sell?

I’ll point out that for VLF monitoring, a 96kHz (DC-48kHz) or 192kHz
(DC-96kHz) sound card works quite well.

Quite so. I have a GPSDO though, so it’s nice to be able to lock to
that. Last week I recorded WWVB (60 kHz) amplitude and phase for 1 week
to monitor propagation. Interesting results to see the fades over 6
days Phase was futile though as their new BPSK mod messes things up.

I’d be interested in the results of your analysis.
Heck, i’d be even interested in the raw data :slight_smile:

And yes, the insanly stupid PSK modulation scheme of WWVB is a pain for
everyone. :frowning:

I switched this reply to the thread I posted last night, which has the
plot and python files. Here is the raw data:

I built a prototype WWVB receiver in GR a couple of years ago, but I
don’t locally get WWVB :frowning: Neither did my LaCrosse clock though, so it
wasn’t my fault :slight_smile:
