Some eQSL-cards are just beautiful:

Use of digimodes on 319 THz

I enjoyed building a simple infrared transmitter and receiver.
The circuits are designed around IR LEDs using a wavelength of 940 nm (frequency 319 THz).
On this high frequency it was simple to transmit and receive SSTV pictures, over a long distance of 30 cm, as you can see below:

It is a first trial and a lot can be improved.

Great fun with this interesting DIY kit (3 euros)

How about using a 5W IR LED ? Or other digimodes. I already used FT8 succesfully (Am I the first using this digimode on this high frequency :-)  )
