- HAM Radio CW Shortwave Transmitter Receiver Forty-9er 3W CW Shortwave Radio Transmitter Receiver Telegraph DIY Radio Kit

Excellent parts. Better documentation in English would be a plus.

Great product

This kit comes with, probably, all the parts needed. Unfortunately it comes with absolutely no direction about where to put them other than on the board. There's a spot for a capacitor marked "c2". I see. So do I just pick one at random that fits in place? Also the kit comes with some doghnut-shaped metallic pieces. Those must be where the included spool of copper wire is used. I guess I cut the wire in half and use half for each doughnut? I'm sorry but very uncharitable words come to mind but instead of using them I'm just going to return this thoughtless mess.

I enjoyed the kit very much I was surprised of it's low price with all the transistors, double balanced mixer, Oscillator, and the lm386 M amplifier. My comment is that the layout marking on the PCB for the NE602AN was backwards the key notch was opposite it should have been, it took me a couple hours of trouble shooting to discover this error, lifted the NE602AN out of the bracket and turned it around opposite of its marking and it works just fine now.

Sure wish I read the language all of the documents are printed in. And we're learning the soldering process. That's how you're selling your product but we're not EET grad students. Between the unreadable paperwork and searching the internet looking for a completed project picture I can print out and build it from that. How hard is it to press Translate while producing your documents so we can actually enjoy building your product.

Received this..package came in rough shape due to enroute transportation. I checked components, looked ok..plan on this for winter project.

I have, without exaggeration, thousands of hours soldering and building electronic components. This CW transceiver kit will not transmit properly. To assemble this kit, you will need to find copies of the schematics elsewhere on the internet. Some components are different from the schematics. Some components are simply missing from the kit. However the board design is not too bad. I completed the kit and have spent several hours reverse engineering the design. I still cannot find why the kit does not transmit the side tone out the RF amplifier block. I would suggest finding a more professionally designed and more functional kit from QRP labs.

The molex connectors are wired backwards! Dont rely on the color of the wires when connecting power! I got a big puff of smoke, and now i need a new voltage regulator before I can assess if further damage occurred. Also, the photocopied instructions contain so many smudges and artifacts that they are almost unusable! There were no instructions on how many turns of wire are needed on the inductors. I later found on the internet that 11 turns for the black one and 16 turns for the colored one (by the antenna) are needed. Board quality is good and dense. I would like to see an option for a BNC or SMA connector for the antenna.

works as should

El kit llegó rápido, las instrucciones son muy pocas y el diagrama es ilegible pero armarlo es bastante fácil. El audio es mejor que el el Pixie aún cuando es menos sensible, la potencia de salida (en carga fantasma) es de un poco más de 2.3w lo que me parece bastante bueno! Toma un par de horas armarlo y funcionó a la primera, no lo incluye pero después le agregué un disipador al transistor final. Tampoco incluye un conector para la antena, aún así por el precio me pareció una excelente compra.

Does not have a metal enclosure as advertised (doesn't have any enclosure)! The diagram is very difficult to read.

Texte toute en chinois mais reste comprehensible. nombre de tours des L3 L4 inconprehensible fouiller le net pendant 3 heures pour trouver un semblant d'explication L2 indechifrable on doit attendre la fin du montage pour essayer de comprendre le quel des deux pieces restante va sur le board. Puis vous rester avec une resistance de 1 watt de 50 ohms les reste ca va. Pour le prix c'est tres bien ca fait travailler les méninges

The kit misses parts
