  • Page 2 Welcome to the Rooster. The Rooster is designed to be a single evening project that will be fun to build and even more fun to use. The Rooster is intended to be a replacement for the FOXX3 kit Kanga offered for many years. The FOXX3 was very popular but had a few issues that we wanted to address with its replacement.

  • Page 4 470pf Important The Rooster is a relatively easy to build transceiver BUT you need to carefully follow the instructions, do not move on a stage until you are sure that you have completed the previous stage correctly and fully. All parts must be fitted neatly and their leads trimmed flush.
  • Page 5 Band Specific Parts Bag :- Stage 4 and Stage 6 Most of the photos below show the 40m Board, if you are building the 30m version your board may be slightly different. Rooster CW Transceiver Rev6 Page 5 of 33 12/02/2024...
  • Page 6 The biggest problem identified with the beta testers was poor soldering and rushing to get the kit built. Do not take short cuts. Each part is as important as the next. Save yourself problems later by taking care at each stage. Rooster CW Transceiver Rev6 Page 6 of 33 12/02/2024...
  • Page 7 Testing your work If your Rooster fails ANY test stage, STOP ! if it doesn’t do what it should it will never do so and finding out why will be much harder. Contact me if you have a problem. Ok we have only fitted one part but that will allow us to do some basic testing on the board.
  • Page 8 Plug a set of Stereo headphones into the ‘PHONES’ socket and power (12v DC) up the board. Again check that the current is less than 20mA @12v Please note : you MUST use stereo headphones as a mono plug will short the audio output. Rooster CW Transceiver Rev6 Page 8 of 33 12/02/2024...
  • Page 9 You may find that Pin 5 produces a louder Buzz than Pin 4. This tests the audio and filter section of the board so now unplug all the leads and move to the next stage. Rooster CW Transceiver Rev6 Page 9 of 33 12/02/2024...
  • Page 10 Stage 3 :- Side Tone The Rooster has a sine wave sidetone generator, much more pleasant than many simple radio kits. The first part we need to fit is a capacitor C16 C16 is a yellow capacitor with a 2.54mm pin spacing, The value of this capacitor will adjust the volume of the sidetone, we have used a value of 0.01uf (10nF) for this.
  • Page 11 And fit it as you did for Q4 before. Make sure it is fitted to match the outline on the PCB and that it is sat squarely as per the picture here. Rooster CW Transceiver Rev6 Page 11 of 33 12/02/2024...
  • Page 12 D6. Stage 5 Mixer The Rooster uses an active mixer circuit that has much better performance than the old FOXX3 ever could offer. We need to fit the 8 pin socket for this chip. The socket, if you look carefully, has a small notch on one of its shorter edges.
  • Page 13 IF you have the latest batch of PCB’s you will find C29 will not be pre-fitted. This is to allow the Rooster to be built for LOWER power use. You will receive a standard value capacitor (100pf for the 40m version or 470pf for the 30m version) with the kit (in the band specific parts bag) this will give the normal output power levels but if you wish you can fit a lower value (22pf for 40m or 100pf for 30m) user supplied if you want QRPp power levels.
  • Page 14 This mixer crystal is to be fitted between the chip socket and the trimmer as shown above. The Mixer IC The mixer chip used on the Rooster is getting very rare in its DIP format, but it’s still available in SMD format.
  • Page 15 There are 5 inductors and unfortunately most are very similar in colour bands. We need to be 100% sure that the right one is used in the right place. Rooster CW Transceiver Rev6 Page 15 of 33 12/02/2024...

  • Page 17 They will then fit correctly on the board. Here are the inductors fitted to the 40m board, of course if you’re building the 30m version the some of the inductors will be different colours. Rooster CW Transceiver Rev6 Page 17 of 33 12/02/2024...
  • Page 18 Solder the centre pin first and check the control is still positioned correctly, when happy solder the two outer pins. Trim the leads flush with the board. Rooster CW Transceiver Rev6 Page 18 of 33 12/02/2024...
  • Page 19 The latest boards have an extra contact hole for the BNC, this extra hole is there for an alternative socket arrangement that hasn’t been used on this version of the Rooster. There is no need to connect anything to this point. This point is only a GND connection.
  • Page 20 At the extrema limit of 10.118MHz I find my own Rooster is down to 600-700mw of RF power, still a useful level if you really want to operate at that frequency.
  • Page 21 Now connect the remote rig to a dummy load, no need for an antenna on the Rooster now, transmit a CW signal on the remote rig (set the power level as low as you can).
  • Page 22 The centre pin of the transistor is the collector, this is connected to the metal plate on the rear of the transistor. Check that the centre Pin of the transistor is NOT connected to the rear panel with a Rooster CW Transceiver Rev6 Page 22 of 33...
  • Page 23 Stage 12: TX/RX LED The Rooster has a LED indicator for RX and TX, we have used a dual colour LED so on RX it is Green and on TX its Red.
  • Page 24 If you have a power meter connect that between the dummy load and the Rooster, check the output power. The lowest voltage the Rooster will work on its about 10.5v, the voltage regulator ( it’s a 8v device) will drop out around 10v as it needs about 2 volts head room. With approx 11v you will see over 1 watt, at about 12v nearly 2 watts, with a 13.8v supply you will most likely see a shade over 2...
  • Page 25 Now connect the Rooster to an antenna (should be suitable for the band in use). If nothing else you will hear band noise. Adjust the RIT to about the 2 O’clock position and call CQ, if called back adjust the RIT for best reception and enjoy the QSO.
  • Page 26 The Rooster, as you would expect, has a LPF on its output. We have included 2 and 3 Harmonic traps too. Here is an example of the RF output spectrum on the 40m Rooster, this was supplied by one of the Beta builders at the RSGB Convention. The 2...
