NW Series Monoband CW Transceiver
80, 40, 30, 20 meters - OUT OF STOCK
The NW8020 is a state-of-the-art monoband QRP transceiver designed to bring Fun, Skill and Pride back into Ham Radio.
Fun, because you find that here is a small rig that offers features of a "Big" rig, but is much easier to operate!
Skill, because QRP contacts are not as easy to make as with the "Big" rig. You develop operating skills that will set you apart from the QRO crowd!
Pride, because you're making contacts, even DX, with a rig that you built yourself!
There are many other things about the NW Series and QRP that will enhance your Ham Radio experience. Take it camping; you can operate it from a gel cell.
Since you built it, you will have a better understanding of how it operates. You will meet other QRP'ers and discover a group of people who are different than many other Hams you may have met.
The NW Series has a superhet single signal receiver, with a variable bandwidth crystal filter. A two-pole active audio filter (from the ARRL handbook) is available as an option. The kit is assembled in steps, and each step is tested before the next step is started. In this way, you can be sure the finished radio is going to work. The silkscreened and solder-masked printed circuit board makes assembly easy.

The audio will drive a 5" speaker, just like the "Big" rigs. The transmitter puts out four to five watts, and is adjustable down to the MW range.
Solid State Keying
The keying and muting is very smooth, and features solid-state antenna switching, so there is no clicking antenna relay. This is true QSK; you can hear interfering or breaking signals between letters. The sidetone is from the transmitted signal, and the level is internally adjustable to suit your ears. It can be adjusted so that your transmitted signal sounds just like the receive signal. This makes for comfortable, smooth, non-fatiguing, fun operation.
What is incuded in the "FULL" kit
A cabinet featuring painted and silkscreened front and rear panels is included. All hardware and knobs are included. Also included in the full kit is the AF-1 audio filter. The AF-l has optional resistors to set the gain and center freq where you want it. The AF-1 does a great job both of reducing background noise bringing weak signals up out of the noise.
