Need a little extra boost for your QRP rig? This nifty little amplifier may be all you need. Believe it or not 20 watts is only 7db (about one S unit!) less power than a full sized commercial transceiver. These compact amplifiers are easily driven by any of our QRP transmitters or any other unit in the 2 watt range, and are available in 20 meter, 30 meter, and 40 meter versions. Advanced power MOSFETs are used for the utmost in efficiency and purity, while a multistage low pass filter is used to assure a clean signal output. Power required is only 12 VDC at 2 to 4 amps, depending upon power output. Complete step-by-step instructions are provided which make building the kit a breeze. The amplifier works well for all modes: CW, SSB and AM. Included case measures 5 W x 1 H x 5 D .

Everyone has a high performance general coverage SW radio, but who needs a converter for LF? YOU do! Youll be amazed; there are a ton of exciting signals down there with hundreds of beacons from around the world along with time and frequency standards from various governments. There are lots of hobbyists running in the one watt license-free band and the FCC is even considering a Ham band with 200 watt power! Many newer SW receivers say they will receive down low, but check the specs just because it tunes down to 100 KHz doesn't mean it can actually hear anything there! Most receiver front-ends optimized for HF don't work well at LF. We designed the lowbander to hear it all, a 7 pole low pass filter along with an overload resistant switching mixer squashes spurious birdies and annoying interference. Hook-up is a snap, with built-in antenna switching between regular and LF antennas. All signals are converted up to 4 MHz, so if you want to hear 136 KHz just tune your rig to 4.136 MHz its that easy. We give you antenna hints as well as web links for info on the exciting world below 400 kHz! For a great finished looking converter, we include the custom matching case set. Runs on 12VDC.

There are no short cuts taken in the design of these units-sensitivity is equal to full size monitor receivers or scanners. Schools, scout troops, clubs and hobbyists use these receivers for teaching, monitoring, and just plain building enjoyment. Any one of these little receivers is ideal for easy chair listening, and with no big clunky box and wiring to aggravate the XYL! All four receivers can be tuned outside of the intended amateur bands. For example, the FR146 two meter receiver will tune any 5 MHz segment from 130 to 180 MHz. Choose your band and enjoy FM repeater and simplex monitoring on a budget! Help a newcomer discover the 220 MHz novice band. Listen in on exciting 10 Meter international FM action.
