Making a portable low power GPS locked programmable WSPR transmitter

[VK5FQ]

I have built this small device and use one to drive my 2200m (136kHz) PA for WSPR.
It can also be used on other ham bands as well.

see https://vk5fq.com/FST4WBeacon.html  for details and links of the build.

That's a really neat project you have built, super tidy and such a nice layout.
