432 MHz Activity |
My activity on 432Mhz ...........NOT QRV YET
During the period of active contesting I calculated and constructed many antennas. Based on this experience and the help of computer programs like Yagi Optimizing, my antenna's currently in use were developed from a DL6WU basic design. For EME I use the F1EHN tracking system which tracks my antenna's automatically to follow the moon.
Station outfit:
| Transceiver: TS-2000X |
|
Preamplifier: DB6NT (Micomm) - 0.35dB |
|
Solid state driver: 100Watt |
| Final amplifier: GS35B |
|
Antenna system: 8 x 4.2 wl DL6WU-modified - 23dBd |
My EME antenna system:
Some Impressions of my station can be found on the photo gallery
May 2002: Although from calculation it was found that my echo's from the moon should be readable, it took until today that it really happens: My echo's
May 2004: First experiments with JT65 mode. I believe this is a more confident way to check conditions for stations with poor echo capability like me.
Jan 2005: Antenna problems. Good VSWR but weak signals. Checking but not sure on the problem. Therefore decided to changing matching system into T-match and also re-new 4-way couplers.
Oct 2005: Finally got a good matching on my test antenna using T-match design.
Jul 2007: Removed all wiring harness in order to replace with new.
Jul 2009: Prepared all dipoles and cable harness to re-enter 432MHz EME, just waiting for a scaffold and much better weather conditions.
