1296 MHz (23cm) band experiments
Click below for two articles I published in The RSGB Radio Communication magazine [1, 2] in 2022 about a low power (ca. 1mW) transmitter for 1296 MHz experiments.

The 1296 MHz (23cm) band has a lot to offer - low band noise, highly sensitive receivers and small yet high gain antennas that are still within the range of what can be made at home.
23cm is influenced to a much greater extent than the 2m (144 MHz) band by large buildings, objects in the way along the signal path and by the weather.
On long paths water moisture can have an effect. Warm air tends to hold higher concentrations of water moisture than cold air, so winter days are often better than summer days.
Here are some of my 1296 MHz band experiments I have had time to write up so far.
