Born in 1961 I'm living with my wife since more than seven years now in a small village with around 400 inhabitans, about 45 kilometers south from Cologne. It is a mid range mountain area, called "Nordeifel", within the "Nature Park Rhineland" (DLFF-102).

Euskirchen-Schweinheim, a small village with about 400 inhabitans, 45 kilometers south from Cologne.

DF5JL/P: HB-1A (40/30/20m CW), Kent Single Lever Key (wired as a sideswiper),
Puggle "Lucy" (as a watchdog), PB-Accu 12 Volt / 7,2 Ah, a coffee mug.

I have tried a lot of in amateur radio, and ultimately realized: contests and the processing of DXCC lists are not my thing, just not "599 TU" -QSOs. I like to experiment, especially in digital modes, but I am even often outdoors, mostly with small luggage and a sideswiper key. I like it simple and straightforward, prefering a piece of wire in the yard rather than a garment spidery construction on the roof.  "Reduce to the max": the good old KISS principle!


Simplify your station

So I have in use:

  • KENWOOD TS-480 SAT, reduced to 5 watts, incl. 500 Hz filter and built-in antenna tuner (focus on digital modes and international broadcast reception) with a T2FD antenna (25m/78ft. long, 5m/15ft. height)
  • TEN-TEC Corsair II, reduced to 5 watts for CW and 10 watts in SSB (17m random wire ant. + ATU)
  • K1 ELECRAFT CW QRP transceiver for 40/30/20/17 meters, with built-in antenna tuner KAT1
  • Begali single lever key, model simplex mono wired as sideswiper (also called "Cootie-Key")
  • PANASONIC Headphone RP-HTX7 (closed, easy to carry, ideal for CW, even for hours)
  • FLDIGI (open and free software for many digital modes / radio teletype)
  • SB-2000 USB interface (Audio IN, Audio OUT, PTT, CAT)
  • a additional 33ft./10m long antenna T2FD at abt. 15ft./5m height and a Solarcon A99 CB-vertical antenna (for (14) 18 - 28 MHz CW / digital modes)

Over 30 years old Ten-Tec Corsair II with Begali Simplex Mono, wired as a sideswiper key.


For QRP portable operations and the holiday QTH are available:

  • Yaesu FT-817ND (HF, VHF, UHF - FM, SSB, CW, DATA, max. 5 watts out)
  • YouKits HB-1A, 3-band CW transceiver from China, which is due to its size and the corresponding AA batteries holders ideally suited for portable use; 7/10/14 MHz, 3 to 4 watts out, DDS VFO, RIT, RX 5 to 16 MHz, 20 memory locations. The built-keyer IC is not used, because of the sideswiper key
  • Kent single lever key (DIY kit), wired as a sideswiper key; or
  • Palm Single ABS Palm Radio (lightweight sideswiper key especially for portable use such as SOTA, GMA or DLFF)
  • Lead acid battery 12 Volt / 7.2 Ah (heavy but sturdy)
  • modified 5/8 lambda CB antenna (5.5m high) plus tripod from a camping rotary clothes dryer and (optional) a few meters antenna wire incl. insulators (for W3EDP antenna in the portable version)
  • a radial set (4 x 7.5m, from former GRC9 German Army communication set)
  • antenna tuner ZM-2 from Emtech ("Z-match")
  • a lightweight headphone

So give me a call when ever you hear me! 72/73 Tom DF5JL
