TrackGen interaction details

I am using an STM32L4 device to control my AD9910 which means I'm writing my own version of the TrackGen code. The manual provides me with the command set and the 115200 8N1 specs for the communication but it does leave silent a couple of points: - is the interface expected to echo/not echo the comm...

Re: Virtual Trackgen

I'm tempted to get one of the ADF4351 board and have a play with some filtering as it's a cheap device. Agreed that it is a cheap device but how do you intend to go about the filtering. The 'simplistic' approach is a LPF that would cut out the higher frequency harmonics of the square wave. But the ...

Re: single board computer

What do you want to on the computer? I've used a RPi 3B+ running a C program I wrote to capture the 137.0-138.0 MHz range from my SDR RSP2 and decode the NOAA FM signals that were passed to WxtoIMG. So it can at least do that. If you want to drive a waterfall etc then you may have more of a challeng...

Re: SDRPlay, Raspberry Pi & Python

I used Python on my iMac to do some simple channel selection and FM decoding on a 2MHz bandwidth data stream from my RSP2. However when I tried to transfer this to my RPi3, it struggled to keep up as Python is not the best choice (in my opinion) for fast real-time data processing. The have hardware ...

Re: Antenna conector

Check the data sheet for the particular hardware you are interested in. For example the RSP2 uses SMA female connectors.

Re: ACARS

I guess 'expensive' is a relative thing and 30Euro (the price of the license as of my viewing the web site today) may be too much for a limited budget. I would suggest that you start off by trying to install the VAC software (or the free VB-Cable) and see how you go. Come back here if you get stuck ...

Re: What is the Waterfall for?

If you look at the frequency/spectrum plot, it is showing the strength of a signal at a frequency at that point in time. If a signal starts, the plot at the frequency will rise higher. When the signal stops, the the line at that point will drop back down to the background noise level. This is showin...

Re: Mac or Windows?

My 2c It is really comes down to what you are used to. Also, legally you can run Windows in a VM on a Mac (as you can buy a copy of Windows on its own) but you can't *legally* run MacOS on a Windows VM (there are ways to run MacOS under a VM hosted by MacOS). Technically, you can run Windows on hard...
