I have found a nice little helper for my IC-705. It is an external Display based on M5Stack Core Basic or M5Stack Core 2. I use it as well for my APRScube.
The Display can show you information like S-Meter, Multimeter, DXTracker or use the internal Keyer for Audio or CW.
I know, the IC-705 can show all this information on the screen. But it costs space, to the disadvantage of the spectrum scopes.
When you use this little gadget, you can use the full size of the spectrum scopes and have all the other information on your M5Stack Display.
It works with Bluetooth and also with USB-Connection. The M5Stack brings its battery, so you can use it without a power supply.
Now a few pictures and the links to the relevant pages
The default application on M5HamRadio. A nice S-Meter with different options.
On this screen, you can find much information. I think it's self-explanatory
You can use it for Audio or CW playback.
The last firmware you can use is the DXTracker
M5HamRadio and M5Stack Core 2
How do you find this Icom "Extension"? Tell me in the comments.
