Taurus receiver board is ready for test

Taurus receiver ready for test

Today the receiver is ready in his first stage. So far known the mods are used and the first QSO is recorded (see *.mov). The next step is de finetuning to hear the stations more easy, have to check the filters and potmeters!

Rotor management extra info by PE1ANS


The rotor soft- and hardware you can find on this site is in the development fase. PE1ANS (OM Jan) had picked up the mean time stage of the development fase with his own few on the software. I nice small movie will show an error in the source code, when you push the button to …

Start with building the Taurus transceiver

Started RX print

“Started with the building of the Taurus TX, 3.5 Watt qrp SSB transceiver” The transceiver is design on two PCB’s and designed by SP5DDJ (see links page). The PCB’s can used for 20,40 and 80 meter homemade TX. A few parts you have to change to change the basic Ham-frequency. In polish you can find …

Rotor management hardware update

Rotor house

In the time we are building on the PCB with the electronics (for PIC controler) I had to bring the old hardware inside a new box. Also the rotation of the Antenna rotor I have to do by hand. But safety first .. the old hardware is build together in a plastic ‘box’ with on …

Found many RF interference from Linksys hardware!

“Today I found the source of a large RF noise on 20 and 40 meter band!” On the next frequencies (14.151, 14.215, 14.274, 14.333, 14.396 and 7.098, 7080, 7.035 and 21.113, 21.172, 21.297) i heard a large spike signal. A signal with an ‘step over frequency’  (harmonic) of 60 kHz. The signal was so strong …

New antenna active ZS6BKW multiband dipole!

Wire lint cable

“New wired multiband antenna is active, here you see how I build this nice antenne’ This great wired dipole (26 m.)will give you a lot of plessure on the HF-bands. On the 20 and 40 meter band you don’t need an antenna-tuner, the SWR is nearly 1:1.1 (40 m) and 1:1.3 (20 m) .. I …

New rotor management with PIC-controler

1st stage

“Start to build a new management system with PIC-controler for the Antenna-rotor” The next pictures will give the few of the development of the antenna-rotor interface with a PIC 16F84 controler. The development is started on a breadboard to find the correct parts and programming of the PIC controler. I have started with the most easy …
