WSPRlite Firmware Upgrade

We have upgraded the WSPRlite firmware to support Type 2 and 3 WSPR messages (compound callsign and six character grid). This upgrade, together with the ability to run a WSPRlite from an Android phone makes it a handy package for a little holiday WSPRing. In this configuration, the WSPRlite gets its grid and timing from the phone (internet connectivity needed). It can also be powered from the phone!

Type 2 and 3 messages have some downsides so please read the accompanying information document before using them. The firmware and associated Config App are available at
