Born on July 08th, 1944 in Glogau/Schlesien (now Glogow in SP6).

From 1951 to 1961 elementary and secondary school. From 1961 to 1964 apprenticeship as a radio-mechanic,

later commercial VHF-Radio and Electronics.

QRV since 1967, operator at the club station DM4GG with callsign DM4HGG only 144 MHz mode A3E low power.

1969 license for individual VHF-Call DM2CFG, only 144 MHz and homemade equipment was here possible.

Building my RX und TX with tubes up to 100 Watts input in A1A and A3E, with 2 fixed QRGs later with VFO and F3E.

Since 1970 teamwork with DM2BQG (now DJ9MG) and building a 4 x 9 Element-Longyagi-Group for 144 MHz

40 meters over ground. A very great success, because Peter has mode SSB homebrew and homemade.

This was incentive for me to built it, too. My dream was a SSB/CW/FM-transceiver VHF and UHF and 2 VFOs,

all with transistors and with a crystalfilter XF9A ( TNX DK2ZF ! ) and 70 cm-Transverter (also TNX DK2ZF).

This was built between 1971 to 1973, a hard work because all was homebrew and homemade.

DX on both bands was no problem anymore, with power amplifiers QQE06/40 and 100 (UHF) to 150 Watts output (VHF).

My ODX on 432 MHz is up to day OY7O wkd at July 2nd, 1978 with 1560 km, this was also European record!

I had a lot of QSOs via aurora in CW, also few on 432 MHz.

In 1979 I had my first MS-QSO in SSB random and in 1980 QRV in HSCW meteor scatter up to 1000 lpm (TNX DK2PR).

I heard some stations (Ws and VE7) via moon bounce on 2m A1A with 2 x 9 elements longyagi, but not enough power for QSO.

Between 1976 to 1981 I was often QRV via satellite Oscar 7 mode B, wkd 4 continents, last QSO at May 10th, 1981 now QRT.

I had maybe 1000 QSOs with about 700 different stations - wkd 45 DXCCs, my antennas had no elevation! DX were mostly in A1A.

(wkd 40 x W1-4, 8, 9 and 0, 13 x VE1-6, 2 x TU, CN8, EL, 9G1, JW9, UC2 - nw EU, UT5, UA4, UL7 - nw UN and UA0)


In 1981 I got license for Shortwave-Bands, but only qrv on 14 MHz with 100 Watts output (homemade), and dipole 40 Meters high.

January 1980 I got a new callsign here in East-Germany, nw Y23FG - I was very frustrated. In used it until December 1992.

After this time with new callsign DL9ZFG and since October 1995 my last callsign is - DJ9FG.

Since 1991 a new QTH 15m high and since July 1998 other home 40 meters over ground with provisional antennas, direction east .

Until 1994 I wkd with my homemade equipment on shortwave and on VHF and UHF with good success.

My homebrew and homemade equipment is now retiring, but still qrv.


My present Working-Conditions now

Shortwave : FT-757GXII only 100 Watts output and a simple 5m/10m wire out my window. DX is very difficult, but possible.

144 MHz : 10m-Transceiver with homemade-transverter and homemade-PA GI7B ceramic-triode and 300 Watts output

________ Antenna HB9CV or 9 Elements Shortyagi 1wl but 40 Meters over ground. (my ODX UA4AQL - LO20QB - 2350 km)

432 MHz : my 6m-TRCVR (or transverter) plus homemade transverter (see later) and GI7B-PA up to 250 Watts output

________ Antenna DL6WU 12 Elements Longyagi. (best DX in this QTH is OH6NJ - KP22WG - 1410 km)

50 MHz : homemade transceiver (or transverter) with VMOSFET-IRF610-PA (see later) up to 40 Watts output


Construction manuals and Calculations from DJ9FG

( Building projects in Ham-Magazine FUNKAMATEUR)

Ladderfilter up to n=10 crystals _____________ 02/1998, 03/1998 and 04/1998

6m/70cm Transverter in Stripline-Technology ___ 10/1998 and 11/1998

432 MHz Linear-Amplifier with 10 Watts Output _ 05/1998

50 MHz VMOSFET-PAs with 1x and 2x IRF610 _ 12/1999 and 01/2000.


Thank you for reading my biography, vy 73 de Rolf - DJ9FG in JO52TD
