Ever since my QO-100 ground station has been operational<\/a> I’ve been using my NodeRed QO-100 Dashboard<\/a> to control my IC-705<\/a> and GQRX SDR software<\/a> to drive my NooElec SmartSDR receiver<\/a>. This gives me a full duplex ground station with both transmit and receive VFO’s synchronised.<\/p>\n\n\n\n

This solution has worked incredibly well from the outset and over time I’ve added extra functionality<\/a> that I’ve found to be useful to enhance the overall setup.<\/p>\n\n\n\n

The latest addition to the ground station solution is a Sennheiser Headset<\/a> that I picked up for just \u00a356 on Amazon (Much cheaper than the Heil equivalents at the HAM stores!) and have found it to be excellent. The audio quality from both the mic and the headphones is extremely good whilst being light and comfortable to wear for extended periods.<\/p>\n\n\n

To incorporate this into the ground station the headset<\/a> is connected to my Kubuntu PC<\/a> and the audio chain to the IC-705<\/a> is sent wirelessly using the latest version of WFView<\/a>. This works extremely well. The receive audio comes directly from the GQRX SDR software<\/a> to the headphones so that I have a full duplex headset combination.<\/p>\n\n\n\n

Audio routing is done via pulse audio<\/a><\/em> on the Kubuntu PC and is very easy to setup.<\/p>\n\n\n\n

Since I no longer have a mic connected to the IC-705 directly I found that I needed a way to operate the PTT wirelessly and this is where the latest addition to my NodeRed QO-100 Dashboard comes in.<\/p>\n\n\n\n

Adding a little functionality to the NodeRed<\/a> flow I was able to create a button that toggles the IC-705 PTT state on and off giving me the ability to easily switch between receive and transmit using a simple XMLRPC node without the need for a physical PTT button.<\/p>\n\n\n\n

\"M0AWS

The PTT state and PTT button colour change is handled by the Toggle PTT <\/em>function node shown in the above flow. The code to do this is relatively simple as shown below.<\/p>\n\n\n\n

The entire QO-100 Dashboard flow has grown somewhat from it’s initial conception but, it provides all the functionality that I require to operate a full duplex station on the QO-100 satellite.<\/p>\n\n\n\n

This simple but, effective PTT solution works great and leaves me hands free whilst talking on the satellite or the HF bands when using the IC-705. This also means that when using my IC-705 it only requires the coax to be connected, everything else is done via Wifi keeping things nice and tidy in the radio shack.<\/p>\n\n\n\n

The image above shows the QO-100 ground station in receive cycle with the RX\/TX VFO’s in split<\/em> mode as the DX station was slightly off frequency to me. The PTT button goes red when in TX mode just like the split<\/em> button shown above for visual reference.<\/p>\n\n\n\n

As you can probably tell, I’m a huge fan of NodeRed and have put together quite a few projects using it, including my HF Bands Live Monitoring<\/a> web page.<\/p>\n\n\n\n
