The Four State QRP Group is pleased to announce the HI-Per-Mite, a high performance audio CW filter. This is a small, inexpensive, but high performance design.
A link to the ordering and information page is on the Four State home page, http://www.4sqrp.com/ Hover over the picture or click the red "Shop Four States QRP Kits" button on the left. Paypal, cash, checks, or money orders are accepted.
Designed by David Cripe NMØS, it features a 200 cycle bandwidth with NO RINGING! It can be used as an external stand-alone unit, and has an on board audio amp for driving a speaker or headphones. It also can be built into a receiver without using the audio amp, or with it if you need the audio stage. This is a very useful accessory for direct conversion receivers or any rig needing additional selectivity. It provides outstanding selectivity and comfortable listening while using earbuds, headphones, or a speaker.
As always, all proceeds go toward funding OzarkCon. Thank you for supporting the Four State QRP Group.
