Long time no update. A lot has happened.

My last post was in January this year. It’s August now. Lots of things have changed around here.

First of all i changed QTH. I now live in a place where i can mount a larger antenna IF I WANTED TO. In fact, if i wanted to get back into some serious radio i WILL have to build a new antenna because my previous antenna got lost in the move. But do i want to? This i will explain later.

Then i changed job. Where before i was working from home and never left the house, read: lots of time for radio, now i have to travel every week. So when i am at home i want to be with the family, work on the garden, the pool, the BBQ and not lock myself up in my office again to do some radio.

Then, and that’s the most important at the moment, the sun has gone really quiet lately. I know the cycle is going down, but i didn’t expect it to go down this dramatically. This was a very short and very unpredictable sun cycle. So to spend money on a tower and an antenna when there is hardly anything to listen to, no. That’s not the plan.

Let’s see. For the moment i just let my SDR create some daily heatmaps and maybe at some point, when the winter comes and conditions pick up again, i will decide to build or buy something.


A second heatmap server has been installed. This time i used a leftover Raspberry Pi and a RTL-SDR adapter. This one is going to cover everything from 24MHz to 1.7GHz. At least, that’s what i understand the RTL adapter can handle.

CubicSDR has progressed into a great piece of software

It’s been a while since i wrote on this blog, but that doesn’t mean nothing has happened in the mean time. Things have progressed a lot on the panadapter front.

In my last post i wrote about the SDRPlay only supporting Windows, well that has changed, SDRPlay now also supports OSX. that makes that i can now use CubicSDR on my Mac and specifically CubicSDR has come a long way in it’s development:

  • I wrote about CubicSDR supporting osmosdr, that has changed. CubicSDR has now moved to SoapySDR. SoapySDR is an open-source platform for interfacing with SDR devices and supports the most common SDR devices under which the SDRPlay. More about SoapySDR on https://github.com/pothosware/SoapySDR/wiki


  • CubicSDR now also supports Hamlib. Hamlib is a library to control radio receivers and transceivers and one of the transceivers supported is my TS-590. More about Hamlib on http://sourceforge.net/p/hamlib/wiki/Hamlib/


  • CubicSDR is going to support more modulations, specifically the digital ones. So we will be able to decode digital signals without the need for Windows decoding software. This is not finished yet, but it’s looking good so far.

  • then there are many small new features like multiple SDR support, RTL-TCP, audio device support, automatic and manual gain control, many UI improvements and many, many more enhancements to come. The developer Charles J. Cliffe is really putting a great effort in building a superb SDR program that is going to give HDSDR a run for its money.

So when i add all these new developments up as of now i will use CubicSDR as my panadapter for my TS-590 without the need of having to use Windows. I removed my RTL adapter from my radio and am only using the SDRPlay from now.
