My equipment

DeviceDescription
Transceiver:

Kenwood
TS-570D

Kenwood TS-570D

I bought TS-570 in January 1998. Since then, I have been working cca 500 QSO's per month. Generally I am satisfied with transceiver especially with DSP.

Power Amplifier:

Skywalker
500W

I bought the Skywalker 500W kit from R.F. Electronic in 1994. I assembled this kit in one day and have been running this little amplifier since today without any problem. I have made over 5000 QSO's and I am very satisfied with it.

Here is my suggestion how to solve problem with DC input power.

Everyone who buys this amplifier discover that the amplifier need lots of DC input power. I solve this problem with separate supply for each module. The collectors supply (2 X 35A) are not voltage stabilized just filtered through electrolytic capacitors of 40000�F (one per module). It is very easy to build power supply with only 2 X transformers, 2 X Gratz rectifiers and 2 X electrolytic capacitors. Voltage for bias circuit must be stabilized but this is no problem since this circuit need less then 500mA.

I bought kit 1KW PA and will be very soon in the air with 1KW.

Antennas:

Cushcraft A3S
Horizontal loop

What to say about A3S? It is a very good array in it's own class, very light, easy to assemble. I have it from 1992 and make lot of QSO's through big pileups. I also bought an add-on kit for 40m band and I am very satisfied with this solution.

I am using horizontal loop (triangle shape) for 80m band. I would like to have 3 el. beam but in my financial situation this antenna is the best I can do and isn't too bad.

Want to buy monobanders for 15 and 10 m and take a part in some WW contests.
