My way to Ham - Radio and beyond :
In summer 1956, as a young 12 years old boy, I was allowed to have a look and climb into a HANOMAG Radio Van from the West-German Border Police BGS (Bundesgrenzschutz), which was operating on a small hill during an exercise in the vincinity of Munich, Germany !
For the first time in my life I saw radio equipment, heard Morse Code signals out of the receiver and was even allowed to press a Morse Key even I did not know the code !
This was an very impressing experience and I have been very much excited and immediately radio-crazy and bitten by the "radio bug" !!!
A few months later in early 1957 (at age 13), I started being interested in HAM-RADIO with a German ex-Military WWII surplus receiver "Torn.E b", which I could buy for 5 Deutsche Mark, that time equal to US$ 1,20 ! Lucky to have an ex-Luftwaffe Funker (German Air-Force LN "Luft-Nachrichtentruppe" radio-operator) available as instructor for Morse-code, basic electronics and many military equipment (e.g. Torn. E. b, KW Anton, E 52 Koeln, FuG 10 Aircraft Radio Set, Radione R3) and even for cryptography (ENIGMA, ADFGXV, "paper and pencil", Caesar Code, Tarntafel etc.) for the next three years, I was collecting a lot of knowledge and experience for radio communications and equipment ! He was my ELMER and I own him a huge amount of gratitude !
In 1958 I joined the THW Technisches Hilfswerk (Technical Disaster Aid) and I alone have been the "communications group" in our city, having two LORENZ (banana-like) FuG 6 radios. I have been sent for training on the FuG 7 Command Radio Van to the training school of THW in Wolfratshausen, south of Munich ! In September 1961 I finished my voluntary membership with THW, because
in October 1961, not even 18 years old, I joined the German Bundeswehr Signal Corps. After a 3 months General Infantry Training at a location near the Czech border I have been transferred to 3.(FuKp)/FmBtl 4 (which was the first FmBtl of the new Bundeswehr established in July 1956) in "Raffler Kaserne" in Regensburg, where I have been intensively trained on the old US WWII HF CW and AM radio equipment SCR-506, SCR-193 and GRC-9 for 3 months ! I still remember the very nice time there and many people of the staff !
There I also saw one of the BGS HANOMAG radio vans again (many BGS members changed to the newly established Bundeswehr in 1956 including their radio vans) and I learned that it was a "BGS Funktrupp M", a "Germanized" US SCR-193, consisting of a BC-348 receiver and a BC-191 transmitter refurbished by "STEG" and painted in light-grey color and with labels in German language. We even had the same SCR-193 set-up as a fixed installed radio station in our barracks serving in a NATO CW Radio Net ! After 6 years I was literally back to my beginnings !
My first "hands-on" to RTTY (or RATT) with the good old GRC-26C and GRC-26D shelters on a MAN truck with heavy, oily and noisy mechanical TELETYPE and KLEINSCHMIDT "steam-teleprinters", COLLINS R-388 and R-390 receivers, the CV-116 and CV-182 RTTY demodulators as well as the BC-610 and T-368 transmitters and my first "hands-on" to Cryptography with the HELL H-54 "Kaffee-Muehle" (coffee-grinder), see: www.cryptomuseum.com/crypto/hell/h54/index.htm and the complicated sweat-producing "Reihenschieber-Handschluessel" was in early 1962 in this Signal Corps unit !
Since that time I am hooked on RTTY ! I have been very much fascinated to work with "real" cryptography and to see text being typed on paper through radio !
In addition to the old US WWII HF equipment (which I had great fun to work on with the morse-key), we had the new developed German mobile 100 W and 400 W RTTY systems.
The 100 W system in an UNIMOG van consisted of a SIEMENS E-309 receiver with the FSE-1300 RTTY demodulator and T-100 teleprinter and a R&S SK-010 transmitter as well as a TFK R-77 monitoring receiver which we used to listen to RADIO LUXEMBURG on 6090 KHz ! The 220 VAC power-generator with a BMW engine was on a two-wheel trailer !
The 400 W system was in a 3to FORD truck shelter (which was soon changed to a 5to MAN truck, because the FORD was not strong enough to carry the weight of the equipment in the shelter !!!) and consisted of two SIEMENS E-311 receivers with the excellent PFITZNER TG-440B RTTY demodulators and the older SIEMENS T-37 teleprinters and a R&S SK-050 transmitter as well as a SIEMENS/HELL KF-108 Kleinfax which was not allowed to be used because it lacked a crypto unit ! All FSK, CW and AM only. Also here the 220 VAC power-generator with a BMW engine was on a two-wheel trailer !
That time there was no SSB radio equipment yet, the French THOMSON CSF ERB-281 HF-SSB radio set came later! The VHF-RTTY system with the SEM-25, a WT-1 MODEM and a SIEMENS T-100 teleprinter in an UNIMOG van also came later !
I served in the Bundeswehr as instructor for CW, RTTY and Cryptography until end of September 1964 !
The picture above showing me typing on a T-100 teleprinter was taken inside a 100 W RTTY UNIMOG van in 1964 during an exercise.
End of 1964 I received my license with call-sign "DJ2EI" and I am active in "steam-RTTY" since then ! I bought my first teleprinter, a used Siemens T-37h, end of 1964 and hooked it to a home-made "Twin-City" demodulator with tubes. Receiver was a HAMMARLUND BC-1004 and transmitter a HEATHKIT DX-100 which I modified for FSK ! I built 5 or 6 "Twin-Cities" with a tuning-scope using LB-8 cathode-ray tubes from the WUERZBURG RADAR ! After the uA709 IC appeared I built at least 25 "ST-5" demodulators as well as several "DJ6HP-001 series" boards ! Later I went QRV in almost all Digi Modes with SSB equipment, especially AMTOR since the beginning of the 80's with a MKII board first, then an AMT-1 and AMT-2, then PACTOR 1 since it appeared in 1991 with the PTC-1 board (which I integrated into a military MODEM) and also a PACTOR 1 software (made by Tom, HB9JNX) used with an external MODEM/AFSK, a "DSPCOM" MODEM for CW, RTTY, AMTOR andPACTOR 1,FELDHELL and PSK since 2000 and now ROS since 2011 with sound-card and software. I owned several SIEMENS FSE-30 and FSE-401 demodulators, which I modified for audio input instead of normally IF 30 KHz ! In addition I had the FEC-100 and ARQ-1000 units. Now I also have the CHX-200F1 MODEM. From TELEFUNKEN I had the TgFs-127 Demodulator plus the Antenna-Diversity-Unit ! From Pfitzner I had the TG-440B and the TG-44 ! Several CFA demodulators from Northern Radio, U.S.A. from the 50's as well as the CV-278/GR for the GRC-46 !
I collected many different teleprinters over the years and had a nice collection of more than 70 models, many exotic like the TELETYPE Model 28 ASR with gearshift, KSR and RO and the small "compact" version, the electronic Model 42 Baudot and 43 ASCII, Model 37 and 38 ASCII, even the Teletype Model 40 TEMPEST (hundreds of IC's on many many PCB's) with monitor screen and high-speed chain-printer (used mainly for crypto-applications), the very heavy AN/UGC-74B made by HONEYWELL, the Siemens T-150 first "hand-carved" laboratory model and a Siemens T-1000 with the very rare magnetic-cassette-tape attachment, a HASLER SP-300, OLIVETTI T2CN and TE-300, a PHILIPS PACT 220 (which was the basic for the Bundeswehr FS-200Z/FS-220Z produced by TE-KA-DE) as well as a MITE AN/TGC-14A(V) miniature teleprinter in a fiberglass case and with 24VDC motor ! I also had a version for use in airplanes with aluminium case and 110 VAC 400 Hz motor ! And a very rare MITE attache-case 110 Bd ASCII terminal with a horizontal type-cylinder, moved by many strong solenoids, wheels and thin steel-wires and springs - no motor !
I owned many different receivers and transceivers from WWII era, both US (BC-342 and BC-348, RCA AR-88, HAMMARLUND SP-600, NATIONAL HRO, SCR-506, AN/GRR-5, ECHOPHONE EC-1B etc.) and German Wehrmacht (several different Torn E b versions, Torn Fu b1, Torn Fu d2, FuG 10 aircraft radio, UKW E e, Radione R-2 and R-3 etc.) ! And sure many from the "Vietnam era" and later (AN/GRC-9 with LV-80, AN/GRC-19, Collins KWM-2A, COLLINS R-388 and R-390, HARRIS RF-230 and RF-301, TMC GPR-90 and a HAMMARLUND PRO-310 from the 50's etc. to mention only a few) ! Many receivers, transmitters and transceivers made by Siemens (E-309, E-310, E-311, E-401, E -410,FuG 100, CHR-531, CHX-240), Telefunken (E-127, E-724, E-1200, E-1501) and Rohde&Schwarz (EK-07D, EK-070, SK-010) and a REDIFON FuG 15 with FuV-100 (used by the BGS) followed with the years !
Amateur radio equipment have been various types from ICOM, KENWOOD, YAESU, TRIO, STAR 700 and HEATHKIT HW's and SB's! Never owned a DRAKE !
Testing of various different commercial and HAM RADIO demodulators and MODEM's was one of my special interests ! I modified several Siemens FSE-30 and FSE-401 for audio-frequency input instead of originally IF !
I enjoy very much "talking with my fingers" !
After my service in the Bundeswehr I stayed in the radio, RTTY and cryptology business (for Military, Special Forces, Intelligence Services etc. and Foreign Affairs) for almost all the time until retirement in 2004 ! During that time I have been sent to several Crypto and Radio Equipment manufacturers for training and also travelled around the globe to do training lessons for the users of the equipment ! Just to prove that it is working I built a "Vernam tape-mixer" (Mischer) with two Siemens electronic tape reader heads and XOR logic IC's ! The cipher-text output was sent to a FACIT 4070 paper-tape punch! Lot of fun to see it works !
I am very familiar with the "RS-6" Spy radio set, the Wandel & Goltermann and Pfitzner "SP-15" Spy radio set as well as the Pfitzner/TELEFUNKEN "SP-20" units and the "HARPOON" system SY-5000 / FS-5000 from TELEFUNKEN with built-in crypto using High-Speed-Digital-Data and not the traditionally Morse-Code anymore! See www.cryptomuseum.com/spy/gladio/index.htm
I am familiar with many HARRIS and COLLINS HF radios and many different Voice and Data Crypto-equipment of "Western origin" !
I am also familiar with the US military RATT systems GRC-46 (with GRC-19), GRC-122 and GRC-142 (with GRC-106) as well as the KW-7 crypto unit !
After the "fall of the wall" in 1989 I collected extensive knowledge on ex-GDR (DDR) RFT Funkwerk Koepenik radio equipment, e.g. EKD-100, EKD-300, EKD-500, EZ-100 RTTY demodulator / preselector and especially SEG-15D and SEG-100D HF-SSB transceivers as well as RFT electronic teleprinters. Also Warshaw Pact equipment like R-130 and R-134 HF transceivers, R-4, R-5, R-155, R-326, R-396K receivers as well as R-350, R-353, R-354 and R-394 "Special Forces Radios" ! And the Yugo RU-20, which is actually a COLLINS PRC-515 !
For the HAM-RADIO hobby, main activities have been (and still are) home-construction of RTTY MODEMS etc. as well as modification, testing and use of ex-Military and Spy radio equipment for the hobby.
The picture below shows a TE KA DE "FS-200Z" electronic teleprinter, based on the PHILIPS PACT 220 with a dot-matrix printhead. "Made in Germany" in the 1980's for the Bundeswehr !
This picture shows a TELEFUNKEN "HARPOON FS-5000 High-Speed Digital Data HF Radio Set" also "Made in Germany" (with home-made frequency input module and modified for Morse-Code) which wasused not only in Bundeswehr LRR (Fernspaeher) units !
No more electro-mechanical like the ENIGMA, no more pure mechanical like the HELL H-54 or the US M-209 ! This is more modern Crypto equipment from the 1980's ! Fully electronic, processor-controlled, LCD 1x40 char. with thermo-printer unit and "Made in Germany" !
