Current 10 meter propagation
Web5. I want to build a Radio Propagation Beacon but I would like to find an integrated circuit that does most or all of the work of the transmitter. Transmit to 28Mhz (Ham 10-meter band) Allow me to feed it Morse code audio and for it to transmit that. As cheap and simple as possible, such as a single-chip solution. WebLong-time users have found that the upper HF bands are reliably open for propagation only when the average number of sunspots is above certain minimum levels. For example, …

If you ever enter the JA contest, each Op sends their age, rather than the number/code etc. Whilst the average age is probably around 68 as you suggest, there are still plenty of ops in their 20s to 30s. However the trend is (unfortunately) FT8 type things.
