Nice kit product yet flawed  Time owned: 0 to 3 months
It is difficult to critisize a kit such as this, for its price, what it requires to get up and running , it seems like a really good deal.
It is advertised as a complete SSB board/ transceiver needing only the wiring up of parts, power, tuning.
Yet it is also flawed: It is advertised as ready to go once wired up but its performance is lacking in a number of areas.
Here are a few (not all) very significant annoyances:
The transmit audio quality is very poor, it needs significant mods to improve inteligibility.
There are receiver whistles, clicks and tuning noises in the stock kit without getting into mods to correct these issues.
Some internal receiver noises are significant enough to drown out weaker signals.
I would not reccomend this kit except to those adept and experienced in modifing.
The kit is unrefined.

For the price, it's fantastic.  Time owned: 6 to 12 months
For the price, it's fantastic. Nice clean analog receiver that you just have to hear to believe. 20+ watts of clean output if powering the PA with 24v. At $60 shipped, this is a steal of a kit.

Fantastic learning experience  Time owned: 0 to 3 months
I bought my first one not knowing a thing about the Arduino VFO. Wow, the chance to modify it is endless! My first contact was with a ZS station! This is a no fail "kit". I put the kit in quotes because everything is built and the user only needs to connect a few components such as the antenna jack, tuning pot etc. I operated mine for a few weeks mounted in the plastic case used for shipping. My present version uses a GPS module to keep the frequency within .003 Hz. I have used the Arduino to act as a VFO for and old Globe transmitter playing around. The best $59.00 I ever spent on tuition. Tons of help on the BITX forum and folks are always making improvements you can upload to the radio. Best part is the software to do all the neat stuff meets that critical HAM need... It's FREE. I can not recommend this high enough I would give it a 10 if the review would let me!

Great kit radio  Time owned: 0 to 3 months
The BITX40 got me back into kit building. The kit as received makes a serviceable 40 meter SSB transceiver, but it really is a starting point for hardware and software modification. There is a very active user community that provides assistance and many good ideas for mods. Great fun!

Low cost 40m QRP transciever  Time owned: 0 to 3 months
The Bitx40 kit is a great way to get an excellent 40m receiver and QRP transmitter in an easy to build kit. The kit uses the Raduino VFO, an arduino-based tuner which provides a screen readout of the operating frequency.

Building the kit means soldering wires to various components and then plugging them into jacks, about an hour or two of work with a soldering iron and wire stripper. All of the parts on the board are already mounted, you only have to connect the peripheral components. You can take more time to mount the board in a case (not provided) if you would like. You will have to provide your own small speaker, 12V power supply, case and headphones.

Instructions could be more detailed, however the build is fairly simple. A growing group of builders are here: https://groups.io/g/BITX20/ . Note that the group is named BITX20 after previous versions of the Bitx.

The Bitx40 covers the 40m ham band from 7.00 to 7.30 Mhz. With the Raduino, there is no drift, which is a big improvement from the old analog model of the Bitx, and makes the user experience much better.

This kit is simple enough for a beginner, and also provides the radio electronics tech many opportunities to mod and enhance the radio. The design is a good one to learn about the workings of an SSB transceiver. The Raduino, an arduino based VFO (variable frequency oscillator), offers the ability to modify the program controlling frequency control, and may lead to future mods.

As of January, 2017, there have been some reports of damaged kits in the mail, however the manufacturer is working on improving packaging. Paypal offers buyers some protection.

I rated the Bitx40 kit as 5-Great! because it is a low cost way to get a fully functional 40m SSB transceiver. I think the receiver is excellent. I am still evaluating the transmitter. At 7 watts, the quality of the antenna, band conditions and operator skills are a big part of successfully making QRP SSB contacts. I have made contacts in the range of 700 to 1000 km, but generally with low audio reports. I am still testing and evaluating the transmitter.
