Four State is very pleased to continue the availability of Dave Benson K1SWL's famous Freq-Mite frequency counter.
Upon retirement, Dave graciously offered the kit to us to continue production.
Along with his SW+ transceiver series, the Freq-Mite is one of his signature designs.
The Freq-Mite provides audio frequency annunciation, and is intended to be installed as a frequency counter inside a
rig. Thus providing an inexpensive alternative to an LCD display for small rigs.
While a builder may balk at dedicating a costly frequency counter in an inexpensive or homebrew rig,
this Morse counter alternative will be the perfect addition. It is inexpensive,
small, and easily installed - a panel cutout is not required. The kit is complete - excluding an
enclosure which is not included due to the intended application.
