40m Projects - SSB Transceivers

Click to enlarge40m DSB Transceiver by MØDAD
My design is in fact a combination of several proven smaller circuits from different DSB rigs which I soldered together to find the best performance. All the components are easily obtainable, it has a good band coverage and stable signal.

The transceiver described here is remarkably simple based on popular communication building block MC1496. It is fairly simple to build because most of the functions are performed by MC1496.

In the ages old Q-code formerly used in telegraphy communication, "QRP" meant "please reduce power", or, if followed by a question mark, "should I reduce power?" Well, Morse code is slowly dying out, ...

After building the BITX, we rethink the project with integrated circuits and arrive at a surprising result. With few components we develop a simple and efficient transceiver.

Click to enlargeARARINHA #4 - Simple QRP SSB TRX 40m 8W by PY2OHH
ARARINHA 4 is an evolution of project ARARINHA that it looks to be a simple radio, cheap and efficient for SSB. The components of the assembly of the radio are of easy acquisition in the Brazilian market and in we look them to place minimo of components to facilitate the assembly.

The 'Beach 40' is a simple yet practical voice transceiver for the 7 MHz amateur band. Go any simpler and it's hard to get contacts.

Click to enlargeDSB 40W 40m TRANSCEIVER by PY5BE
This is the great transceiver used by our friends of South Brazil. They built 18 rigs like that (november 2004).
Because the strong signal , stability and audio quality we talk to Jair, about the circuit, mainly looking for the VXO design and he kindly send us the schematic.

The 'Knobless Wonder' is a simple fixed frequency SSB voice transceiver for the 7 MHz amateur band. It is basically the IF and audio end of a BitX.

Click to enlargeMARITACA - 40m DSB/CW 8W TRANSCEIVER by PY2OHH
O Maritaca tem 8 Watts de potência de saída, podendo chegar aos 12W dependendo da tensão de alimentação. Toda a recepção foi derivada do projeto do Jair pois tem um rendimento excelente.

The 'Micro 40' is a simple DSB voice transceiver for the 7 MHz amateur band. A single NE602 forms both the transmitter's balanced modulator and the receiver's product detector.

Click to enlargePIXIE 2 DSB MODULATED by PY2OHH
In my might a DSB Pixie is a big challange, knowing that I had excellents results from a CW Pixie and a chance to study a DSB modulation. We come again to internet and collet more informations, now about SSB and DSB.

Click to enlargeThe VK3YE Micro 40 DSB Transceiver by AA7EE
At this point of course, I was committed, and set about building what I hoped would be the first DSB rig I’d build from scratch that would actually work. I have made a few changes to VK3YE’s schematic, and will describe them here.
