NEW ! CATsync QO-100 Edition
The CAT Tool for WebSDRs
CATSync allows you to syncronize public WebSDR receivers with your real rig connected via CAT control to your computer. It supports the classical WebSDR as well as Kiwi SDR interfaces:
- Control any public WebSDR server by means of 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 realtime !
- Click on the WebSDR waterfall and retune your rig in realtime.
- Syncronizes both, frequency and mode changes (CW, USB, LSB, AM, FM)
- Listen to the same frequency as your rig via web SDR or viceversa
- Ideally suited e.g. for people suffering from local QRM or working in nets
- Can track RX or TX VFO (e.g. to find that split of a DX station) if radio CAT command set of your rig supports both independently
- Can be interfaced with popular logging software using OminRig or via VSPE port splitter.
This software can help you to bring you back into ham radio when you are suffering from local temporary or permanent high noise levels in an urban QTH location.
You can download a functional Demo from these links:
When installing this software you may get a warning by your Windows Security System saying that this application is from an “Unknown Publisher” and therefore recommends not to install it, as it may be a malicious program.
See my blog post in this regard:
Are my installers secure?
Note: If my app crashes on startup, please install Microsoft Visual C++ 2013 x86 redistributable runtime files (see system requirements below)
Make sure it’s really x86 and not x64 (even on 64bit Windows systems !!!).
The demo has all the functions of the full version, with the exception that it will not retune the web SDR audio in realtime (you only see the web SDR frequency updating, but the audio remains on the former frequency). You can only retune the audio to the new frequency manually. The new Click + Tune feature is limited by 90 seconds per session.
If the demo works on your system and you like the software please consider getting the full version. The full version is tuning both frequency and audio syncronized in realtime and now even bidirectionally!

Microsoft .NET runtime libraries 4.61 or later must be installed (from Microsoft site)
Microsoft Visual C++ 2013 (x32 version) redistributables must be installed (from Microsoft site)
OmniRig CAT software must be installed (Freeware from DX Atlas site)
Many ham shack PC’s already have those components installed, since many other third party software make also use of them.
CATSync supports up to two switchable radios connected via two separate serial ports.
The program is very easy and intuitive to use. Try the demo and see for yourself.
This application tunes the web SDR in realtime, however given the way how a web SDR works there may be a light latency between your real rig and the WebSDR audio due to the waterfall and audio transmission and codec decompression time required to travel from the SDR host server to your PC speakers.
Please note that not all radios support seperate control of RX and TX VFO via CAT. Some radios only allow control of the currently active VFO. (e.g. my TS590 does support it, while my IC7300 doesn’t)
See demo video of CATSync V1.10 in action with my Kenwood TS590:
NOTE: Users of V1.2x versions continue to receive free critical bugfix versions when they become available.
Upgrades from V 1.2x to V1.3 and later are not covered by free upgrades anymore and need a seperate purchase
