Three Band Low Pass Filter PCB Kit

Lowpass Filter PCB Kit for WSPRlite and General Use

New compact PCB for better choice of enclosures and improved high frequency performance

Three options:

  • Board kit only - use to mix and match filters using our band packs or your own components.
  • Board kit plus band packs for 160m, 80m and 40m - perfect for use with the WSPRlite Flexi or Classic
  • Board kit plus band packs for 20m, 15m and 10m - perfect for use with the WSPRlite Flexi

An automatic discount will be applied if ordering the 'board kit only' option plus any 3 band packs. The total cost will be the same as for the 'board kit plus band packs' options offered here.

The filters are selected using jumper links (supplied).

Board Kit includes PCB, 2 x jumpers, 2 x header pin arrays, 1 x SMA tail, 1 x SMA socket, 1 x cable tie.

Enclosure Options:

Options here apply to PCB V1.2 Nov 17 onwards. Print your own enclosure! Lots of folks have 3D printers and are desperate to find a use for them. Maybe you have one yourself or know someone who has one? We provide the files free on Thingiverse. Click here.

Buy a printed enclosure from a third party:

We recommend PLA or ABS plastics.

    Only available as a kit

    Posted by Ian Barrie Egerton on 5th Dec 2019

    Whilst the multi-band filter kit is supplied in various versions (none with a case), completed versions are not.offered by SOTABEAMS! I would prefer to buy these filters as individual band filters ready built and in a case.

    Easy Build

    Posted by Bob Cowdery on 27th Jul 2019

    I have built 3 of these, the first was a version 1 and two version 2. The v2 board is a good improvement. Building is easy. It would be nice to have a 6 or even 8 LPF board as I've had to put 2 together with appropriate switching to cover 6 main bands.

    A must have!

    Posted by Brian on 2nd Jul 2018

    I purchased the low pass filter PCB kit after looking at the WSPRlite Flexi's spectral output without a filter. Yes, you absolutely need a filter with the Flexi. Thankfully, this PCB kit made that job so much easier! Components were very easy to solder thanks to the well planned thermal pads. I would highly recommend this kit.
