Hi All,

Hopefully there maybe someone on this group that can set me in the right path.

I am looking for readymade, set and forget, standalone VHF/UHF WSPR transmitters, similar to the Zack Teck https://www.zachtek.com units?

I welcome any ideas that you may have that will enable us to get a 2m and 70cm WSPR Beacon operational in ZL land?

Hi Selwyn

You may take a look at the RFzero platform. Among other things it is used by the KH6HME/B beacon on 2 m:

The RFzero can be used as a stand alone WSPR transmitter from about 2 kHz to 23 cm:

Adding more power is trivial:

Unfortunately, the RFzero is currently sold out. But I hope to have a stock again soon.
