This relay-switched LPF board kit can have up to five additional LPF's plugged in, permitting the Ultimate3 and Ultimate3S QRSS/WSPR kits to sequence between 6 bands (including the LPF on the main U3/U3S board). The board size is 80 x 37mm, the same as the U3, so the boards stack together using four 25mm hex spacers. The plug-in LPF modules are available separately, click here.

The kit can also be used with your homebrew radio projects!

The photos show the relay-switched LPF board plugged into the back of the U3 kit. Note that my photos below show NO additional LPF's plugged in (as I only had one built LPF at the time of those photos).
