IC-705 IC-9700 scope setup

On YouTube there are several videos about setting up the spectrum scope of the Icom IC-705 and IC-9700. Last in this post I have linked one of these videos and I have actually done every step. It is now much better then the original settings.

I’m using colours like the one in SDR-Console software because that is how I’m used to have it.

The REF adjustment is very good to adjust when needed, to get the best contrast in the scope.

Also adjusting the SPAN to what you would like to see at the moment is a great function.

But, the best improvement for me was to change CENTER Type Display to Carrier Point Center (Abs. Freq.).

Here is the video from Ham Radio DX channel:

How to use WiZ lights with Domoticz

WiZ Connected is a series of lights and other Wifi connected IoT. The units are cheap and works well. The WiZ app is actually good and easy to use. But, if you have a Domoticz system you would of course like to integrate the WiZ units. Below are two solutions:

1. Use the Domoticz plugin

Install this plugin:
https://github.com/sydspost/Domoticz-WiZ-connected-plugin
If you are lucky everything goes OK and you can control your WiZ units.

2. Use UDP commands

I will describe my solution for a Windows system. If you are running Linux I guess it is almost the same.

  1. In your router, add a static IP to your WiZ lights.
  2. Add a virtual (dummy) light in Domoticz.
  3. Download Swiss File Knife and copy just the exe file sfk.exe to a folder, that you will use in step 5 below
  4. In the virtual light you created, have a level for every action you would like, for exemple ”Off” and ”On”.
  5. Connect the level to a script action, see the screenshot below
  6. Now you can control your WiZ lights!

The UDP command lines

I got the idea from this site:
https://aleksandr.rogozin.us/blog/2021/8/13/hacking-philips-wiz-lights-via-command-line

I noticed for sending from a Windows cmd you need to escape the ” sign. As an exemple the command for a light is like this (replace the IP address xx.xx.xx.xx with your fixed IP-address of your light):

Turn ON

sfk udpsend xx.xx.xx.xx:38899 -listen {\"id\":1,\"method\":\"setState\",\"params\":{\"state\":true}}

Turn Off



sfk udpsend xx.xx.xx.xx:38899 -listen {\"id\":1,\"method\":\"setState\",\"params\":{\"state\":false}}

Good luck with your WiZ lights and units!
