Here is a table of the current equipment
I have for operating the
AMSAT International Phase 3D satellite:
| Band | Antenna | Rig | Output power | Noise figure | Note |
| 145 MHz TRX | Orthogonal Yagis | TS790S | 50 W | ~1 dB | Antennas not installed |
| 435 MHz TRX | 6 turn Helix | TS790S | 50 W | ~1 dB | Antennas not installed |
| 1269 MHz TX | 60 cm Dish | Homebrew transverter | 10 W | ~1 dB | Antenna not installed |
| 2400 MHz RX | 21 turn Helix | Homebrew converter | - | ~1 dB | Antenna not installed |
| 2400 MHz RX | 21 turn Helix | Modified MMDS converter | - | ~2 dB | Antenna not installed |
| 2400 MHz TX | 21 turn Helix | - | - | - | Antenna not installed |
| 2446 MHz TX | 21 turn Helix | - | - | - | Antenna not installed |
| 5668 MHz TX | 60 cm Dish | Homebrew transverter | 4 W | - | Antenna not installed |
| 10450 MHz RX | 90 cm Dish | Homebrew converter | - | 0.7 dB | Antenna not installed |
| 10450 MHz RX | 38 cm Offset Dish | DB6NT converter | - | 0.9 dB | Antenna not installed |
| 24048 MHz RX | 60 cm Dish | - | - | - | Antenna not installed |
| IR Laser | 10 cm telescope | Homebrew | - | ~20 % QE | Philips PMT |
| IR Laser | No optics | Homebrew | - | ~20 % QE ? | Fairchild 10 cm PMT |
I still need to construct a suitable transverter
for 2400/2446 MHz (I have an old Nokia radio
link that is suitable for converstion
at about 2 W output) and a receiver for 24 GHz. I also have
a suitable 10 W power FET for the final.
Need more time, initiative and some elbow grease ;-)
My technical class licence does not allow me to operate on 21 or 24 MHz bands.
Nor do I have a 400 bps modem yet either,
but I do have a Motorola 56001 DSP evaluation kit
that should be a suitable platform for
this.
Oh, and an azimuth/elevation rotator would
be cool. I need to cash some junk to afford one;
they cost a fortune. Maybe an old surveillance
camera manipulator ?
