Thanks, Rob! CATSync seems to allow control of a web-based SDR from any OMNI Rig-supported radio via CAT control (which is the majority of transceivers). It appears CATSync allows control of tuning and mode changes via your radio and from the web SDR interface back to your rig.
One interesting use of this would be to use a remote SDR for receiving while using your home antenna for transmitting. This could help those inundated with RFI at home. While this might not be an allowed practice for contesting (having your receiver and transmitter in two different locations) it’s certainly permitted if you want to check in with a net or chat with friends. You don’t need CATSync to do this–you can always manually tune a web SDR separately–it would simply facilitate keeping both your RX and TX on the same frequency.
CATSync has a free trial with limited control–you can purchase the full version for 9.95 EUR.
Introducing CATSync – The new CAT tool for WebSDRs
Oscar, DJ0MY, has developed a new software tool for radio amateurs and SWLs.
CATSync allows the user to control public WebSDR receivers with a real rig connected via CAT. It supports the classical Web-SDR servers as well as the newer Kiwi SDR servers publically available on the internet.
This gives you access to dozens of web based receivers with the comfort of tuning your rig at home. This software helps you to bring you back into the fun of ham radio when you are suffering from local temporary or permanent high noise levels in an urban QTH location.
The software has the following features:
Synchronizes any public WebSDR server with your real RIG…
Supports a wide number of RIG’s (it uses the popular OmniRig engine)
Supports WebSDR and KiwiSDR browser based SDR receivers
Tune the VFO of your radio and see the web SDR follow in real time !
Switch modes (SSB, CW, etc.) on your radio and see the web SDR switch mode in real time.
Listen to the same frequency as your rig via web SDR
Ideally suited e.g. for people suffering from local QRM
Can track RX or TX VFO (e.g. to find that split of a DX station) if radio CAT supports both simultaneously
Can be interfaced with popular logging software using OminRig or via VSPE port splitter
