Doug Pongrance, N3ZI offers up some really nice little kits over at N3ZI KITS. The frequency counter pictured is one I assembled from a kit of his for about 25 bucks delivered.It gives a very nice “big rig” feel to my Ten Tec 40 meter qrp kit when it’s hooked to it. I found the board and components to be of high quality. I received my kit just two or three days after ordering it. A DDS vfo and a communications receiver are among the other kits offered. I give a five out of five stars to Doug’s company.
