N5ESE's Apps for the SWL Freq-Mite

Freq-Mite PCB

(click on any picture to see larger version)

NOTE: 'N5FC' is my former call.
This project was constructed while that call was valid, and you may observe references to it.

NOTE: SWL (Small Wonder Labs) no longer exists, but as of 2023 the 4SQRP Club still
kits the Freq-Mite, and it's still pretty dang cheap. Find it at 4SQRP FREQ-MITE KIT

At only $20, the Small Wonders Labs Freq-Mite has got to be one of the kit-building bargains of the decade! This tiny PCB, powered by a PIC microprocessor, will serve as a general purpose RF frequency counter up to 32 MHz. Instead of visual displays, the device provides frequency readings on push-button command, announcing the frequency with 1 KHz resolution in CW... yes, CW! In addition to serving as a general purpose counter, a switch-settable offset frequency can be programmed to allow using it as a "digital-display" counter on your favorite "analog-dial" receiver, transmitter, or transceiver.

I've used this device several times, and I'll probably use it many more. This page will detail three such applications.
