The MFJ QRP-Cub range of transceivers are truly remarkable. Although super small they have a full superhet receiver, sharp crystal IF filtering, excellent 0.2 microvolt sensitivity, smooth AGC, variable transmitter output power of 1-2.2W and full QSK CW with sinewave sidetone and click free keying. Each transceiver is set up to operate over a 50kHz segment of the band. This 50kHz segment can be shifted to suit the operating conditions. The Cub is truly remarkable, it is extremely sensitive and the audio sounds just like its coming from a full-blown transceiver many times its size. The filtering arrangement certainly does its job. The Cub fully transceives, so tuning around the band means that you can immediately transmit on the receive frequency. It has full QSK break-in keying along with sidetone. There are no annoying clicks in the headphones.
MFJ set out to give QRP enthusiasts a complete CW transceiver that would require nothing extra apart from a key, an antenna and a power supply. The result is this fabulous QRPseries of rigs. Each model covers the complete CW band and offers razor sharp selectivity from the internal 750Hz xtal filter. Up to 5W output can be obtained with an internal control that permits power levels down to milliwatts. Features include AGC, RIT, semi break-in, optional 250Hz audio filter, optional electronic keyer module, superhet with double balanced mixer and narrow front-end tuner, and superb weak signal performance. The built-in speaker provides plenty of audio and there’s also a headphone output socket. (Photo shows MFJ-9040).
