2 Radio Equipment

2.1 Short Wave

There's some wisdom saying that you need a good receiver first of all. The next thing you should think about is a good antenna. I have been experimenting with several antenna types, mainly with the simpler versions of Inverted Vee and Quad Loop, but I have come to the insight that a good multiband vertical is a decent compromise between space consumption and multiband usability. That's why I have purchased a GAP TITAN. The next thing to consider is a sufficiently good transmitter. I solved the transmitter / receiver question first by buying a sturdy Kenwood TS-520S valve TRX. A very good decision, I must say now 15 years later. Around 2001 I bought a second hand TS-930SAT, and this is now my core device.

Here's an overview of my nice little shortwave toys:

2.2 VHF

2.3 Digi modes

  • TNC2S, terminal node controller for 1,2 kBit/s
  • TNC2H, terminal node controller for 9,6 kBit/s
  • TNC2Multi, terminal node controller for 1k2 and 9k6
  • SCS PTC2, a PACTOR modem

2.4 Antennas

As a member of DARC e.V. I enjoy full insurance of all antennas:
