Oscilloscopes have changed a lot in recent years
Has anybody used GNU Radio to make a basic oscilloscope?
There are many generic ADC to USB devices now, some are purpose-built
for use as an oscilloscope. Has anybody tried any of them in a pure
free software environment, either with GNU Radio o
Hi everybody,
How feasible is it to implement multiple home automation protocols (e.g.
Zigbee, Z-Wave, BLE, LightwaveRF) and run them on low cost, low power
hardware, e.g. Raspberry Pi + LimeSDR?
If that particular hardware combo can't handle it, is there any other
permutation that may be viabl

Hi all,
The workshop at OSCAL[1] was successful and on the second day, the SDR
setup was in the courtyard with the info booths where just about
everybody stopped to see it.

Up to now the equipment I've been using has included the RTL-SDR dongle,

other events.

I'm going to Tirana, Albania for OSCAL'17[1] (13-14 May) and will give a

awareness of the event?

What solutions are people using for transmitting on HF bands (1 - 30 MHz)?
There is a lot of information online about upconverters for receiving
the HF bands.
However, like receivers, many of the SDR transmitters only seem to cover
bands above 30MHz[1] e.g.

One specific issue I notice when comparing hardware is that some devices
cover HF bands (under 30MHz) while others don't, e.g. USRP B2x0 starts
at 70MHz. There are some discussions about using upconverters (with
insertion loss, and receiver only) or just buying multiple SDRs.

Based on the USRP specs (up to 100mW output power), I started looking
around for amps that would get me up to a level comparable with other
amateur rigs. This is one of the first I found:

I realize that SDR provides more than one way to view the spectrum and
tune to a frequency, but I can imagine some people feeling comfortable
with a tuning knob similar to a traditional radio. There doesn't appear
to be any technical reason why a VFO knob could not be part of an SDR
application.
