Introducing RadioHat 2
Some time ago I designed a card called “RadioHat” for use with Raspberry Pi computers to allow them to operate as the heart of HF radio transceivers or to drive transverters for UHF and VHF.
I’m making this video to introduce a new generation of that card called “RadioHat 2”. It demonstrates the card on the test bench and explains the changes from the earlier version.

Using a Siglent 1204X-e and a Pi running SOX to IMD Test an IC-7300
Просмотров 4472 года назад
In an earlier video, I showed you how I use the FFT functions of a Siglent oscilloscope to measure the Intermodulation Distortion produced by HF SSB transmitters. In another, I showed a way to generate tones for such testing using a Raspberry Pi. This video uses these two techniques together to test an ICOM 7300 on 20 meters. There are several lab reports out there for this radio so we can comp...
Using SOX on a Raspberry Pi to generate TX Test Tones
Просмотров 3112 года назад
This video shows a simple way to use almost any raspberry pi computer to generate audio signals that can be used to perform tests on amateur radio equipment. The video uses an easily available program called SOX that has been a mainstay of DSP work on desktop platforms for decades. In this video SOX is installed on Raspbian "Bullseye" with the command: sudo apt-get install sox and it's run to g...
Measuring HF Transmitter Harmonics with the Siglent 1204Xe

Hi I’m Mario Vano. I operate amateur radio station AE0GL near Minneapolis and like to experiment with QRP hardware designs and for that, I need a way to measure spurious outputs of my radio transmitters. In an earlier video I provided a simple introduction to the use of the Siglent 1204x-e oscilloscope to measure in-band intermodulation products from an HF two tone SSB test. In this video I’m g...

Hi I’m Mario Vano. I operate amateur radio station AE0GL near Minneapolis and like to experiment with QRP hardware designs and for that, I need a way to measure spurious outputs of my radio transmitters. In an earlier video I provided a very simple introduction to the use of the Siglent 1204x-e oscilloscope for RF spectrum analysis. In that video I showed how to set it up to display a scan of l...
Using the Siglent 1204X-e Oscilloscope's FFT for RF Spectrum Analysis
Просмотров 4,1 тыс.2 года назад
This is a simple video walking the viewer through setting up RF scans of Minneapolis FM broadcast stations as received on a whip antenna. It shows how to use the Math FFT functions of this inexpensive oscilloscope as a "poor man's spectrum analyzer".

RadioHat for Raspberry Pi - quick demo
Просмотров 2182 года назад
RadioHat is an Amateur Radio HF exciter and receiver in the form of a "Hat" for the Raspberry Pi. Radiohat was designed by Mario Vano, AE0GL This is a quick demonstration of the board transmitting a two-tone test pattern into a spectrum analyzer and receiving single-sideband on 20 meters from one of my antennas. Note that the graticule of the scope is calibrated to display absolute power in DBm...
