"SATROVER MK1"
All in one QO100 RX-TX transverter
The transverter package contains the most parts to communicate via the QO100 narrow band geostationary satellite. To make your satellite ground station work. You must add the following parts:
- 12V power supply (or batteries) capable of 2A
- Satellite offset dish reflector 60 to 90 cm diameter.
- 144MHz all mode transceiver what output power level can be reduced within a range of
0,5 to 4 Watt.
- Coaxial cable between 144 MHz transceiver and SatRover.
The SatRover is developed with simplicity in mind. The -rover- in the name means it is intended to use on portable or -rover- operation. Together with a portable 144 MHz transceiver it is small enough to put in your backpack or with your camping gear. There is no need for a computer or external frequency reference.

For many years I have been looking for a 4 band dish feed on my 1.5 m parabolic dish with only 1 coaxial connection. I want to use 1 low loss cable from the antenna to the shack, and no active parts in the antenna mast. Until a few years ago the amateur designs with one cable were limited to LPA, Vivaldi or double rigid-horn feeds. Each type has a number of disadvantages when used in a parabolic dish. Biggest drawbacks are: A phase center which moves with the frequency, and a changing radiation pattern on different frequencies. This design overcomes these drawbacks.

"2400MHz 20W power amplifier |
|
|
This Amplifier is designed by Rens PA3AXA and myself to use with a bare mixer to make SSB on QO100. It has good filtering and 50dB gain Filtering inside the amplifier is good enough to use 28MHz IF. If you want to use a Pluto as a driver be sure the output of the Pluto is adjusted at -7dBm or use an attenuator to get it there. Building manual and instructions here I have some bare pcb's left from the project. If there is any interest please drop me an e-mail pe1ckk@hetnet.nl |

To try some EME tests on 23cm I made myself a dish feed following the design of SM6FHZ and SM6PGP More info can be found here. |

"Conversion TRW 24 GHz Endwave module" |
|
|
Conversion of the TRW 24GHz module. The existing power supply with the module uses a -48V rail supply. All my SHF equipment works the same, using DC power over the coaxial cable and rx-tx switch over is made by switching from 17V (rx) to 24V (tx). This means I made a new power supply to feed the module. On a later date I changed the switched PS modules to a linear type eleminating the spurs from the switching frequency.

Simple use of the wavelab transverter module using chineese ADF boards and Arduino nano controller. For Arduino code drop me a mail. On a later date I changed the switched PS modules to a linear type eleminating the spurs from the switching frequency. More info in Dutch can be found here More info in English can be found here |

Transverter switchover and power distribution |
|
|
The power to all my microwave transverters is by the IF cables, 17V for RX and 24V for TX. This is provided by my shack unit as seen on the small photo. Up to 10 Watts this will also work for the power amplifiers in the transverters (10 GHz, 24 GHz and 47GHz ). The lower bands use external power on the final amplifiers only when transmitting. These transverters are below the roof outside the shack running with only one low loss coax to my dish feed. With one knob I can switch band without changing cables. You can find the diagram for this system following the link below. I made several options to use this system depending on what sequencing is required. More info can be found here |

300 mm prime focus dish f/D 0,37 printed in 4 pieces. I printed a few to use on 24GHz and 47GHz with good results. Fill 20%, After assembly the dish surface is taped with thin aluminium ducting tape as reflecting surface. You can scale the dish smaller or larger in your slicer software. Download STL File |

Seen a lot of 3D printed SMA grips around, but none of them worked well. Or they where to wide or they where to tight to fit. I decided to design an always fit type! Printed many of them with good result. Fill 20%, Download STL File |
