Hi, I am Marijan Miletic', S56A , born 27. 3. 1945, ham operator since 1962, M.Sc. E.E. retired, married, ex YU1,7,3PCF, YU3EA, S57MM, current N1YU, W1BCD.   My early activities were with YU1BCD club station in Pancevo near Belgrade. Ljube, YU7AU was a driving force while Mirko YT7MM did all the paperwork. We designed all our equipments in 60's while studying electronics and telecommunications under the roof of YU1EXY club on the top of the Belgrade University building. I was intrigued with transceivers very early and all my RX projects had a big, secret socket for PA tube.

I've been working on computers since 1970, first with ICL, UK where I learned a lot more English and some digital stuff during the initial 6 month training. My London ham contact was Roger G3SXW while Nigel G3TXF was introduced later. Having won G2LB 14 MHz EU CW trophy in 1976, I met fondly remembered late Al Slater G3FXB and G0AAA mainly FOC contest group. Carl K3RV, my former guest in YU, was working in GB with his charming GM lady who taught me a lot about malt whiskey. I later joined DEC and visited USA for the first time in bicentennial 1976. Lot of hams from New England were wonderful hosts like late Howie W1HZ, JimW2PV and Laci W1PL, George W1DA and famous contesters like K1MM, K1MEM, K1AR, K1DG. I must also mention later friends Andy K2LE, Fred K1VR, Pol WS1M, Randy K5ZD who drove me from PA to my first Dayton in 1988. ARRL HQ was visited on several occasions and I am still licensed as N1YU at Dave Sumners K1ZZ mailing address after passing 3 exams in FCC Boston office in 1978. More recently we established Michael Pupin memorial radioclub with vanity callsign W1BCD. Later developments brought me all the way to California with wonderful introduction to SF by Rusty W6OAT, Bob K3EST and my countryman Bruno, AA6AD. I travelled the world on computer business and ham radio assured a warmly welcome anywhere in the world. Late Jorge LU8DQ is unforgettable with Arthuro LU6ETB translating, Pedro NP4A and Arecibo dish, late HS1WR with HS1YL, JARL Tokyo office and Akihabara. WRTC-96 with NH7/N1YU Hawaii was the peak of my contesting activities.  I organized Skyfest-2000 meeting with Kele, YU1AO under YT6A auspices.  I returned to South America in 2002 as a guest of YU Ambassador Rasa, YU1RL, PT2ZAA.  I enjoyed meeting many PY hams in Rio and Sao Paulo.  I was heavily involved with WRTC2000 project.  I visited Finland during WRTC-2002 event and operated OI2HQ 15 m CW at OH6AC station.  I took part in K1B DX-pedition headed by YT1AD.  We stopped at Dayton on the way back.  I visited often 3V8BB with Hrane.  YT6A until independence, YU6AO in 2006.  Later escapes were to CR3L, CN3A, EF8U, ED8X.  My recent DX-peds include Z6 and ZA portable operations.

In 1972, I build DM2001 TTL keyer with diode matrix and serial number counter up to 1999. It was successfully copied by OM Boris, S58A. With some assistance from an old friend Tom DL7AV, I made HF CW 50W XCVR using 23 dBm RAY-3 balanced diode mixer, 9 MHz IF and frequency counter for a poor stability VFO. Vlado, ex YU3EZ helped me to fine tune input circuits using spectrum analyzer and sweeper. My later designs were more digitally oriented with a numerous variants of electronic keyers, by now my trademark! My first commercial rig was ATLAS 210 followed by early model of IC-735 and FT-1000MP, TS-480 all heavily modified. Heathkit SB-220 gave me a lot of punch even on 160m. I rarely use homemade GS31B QRO in PC housing now.  USA hardware is completed with TH6DXX and 402BA converted to Moxon. Wire antennas cover the low bands on four story apartment building. I worked many times from my former radioclub "Ljubljana", S53AJK nice contest site at  S50L and later helped youngsters at radioclub "Slovenia",   S51SLO .  I also helped 9A7P WWYC Istria group. 

I learned PASCAL programming language in 80's in order to develop my own on-line contest software. Together with first YU 16-bit PDP-11 compatible microcomputer, it had debut in Oct. 1984 CQ WW SSB contest and worked with many bugs in 6.000 lines of code until recently!  It fully supported DX Cluster, Sound Blaster, various frequency management requirements, Morse sending and own keyer receiving. I did some Ph.D. work on HF Morse decoding and DSP beats me heavily in the pile-ups although I know how to handle them being EU CW champ three times! I went as far as allowing PC to make some 200 QSO automatically in 1 991 ARRL DX Contest and then stopped all further research in order to protect my beloved hobby!  Renewed C# windows version was developed with YT7PWR assistance.  I switched mainly to RTTY semi-automatic contesting wining WAE twice in the years 92/94 and CQ WW EU, #2 world SOAB HP in 94/95.  Now in 2017 FT8 devotee.

I wrote many technical articles in various WW ham radio magazines and I was the invited speaker on automated HF contesting at Dayton 1995 Contest forum. It was a pleasure to meet a great host Fred “Foobar” K9VV and go to late Lew, K4VX/0 in Hannibal, Missouri afterwards. I also attended German 1995 Friedrichshaffen hamfest meeting again Fred K3ZO, Jim N6TJ, Dick K4XU and many DL BCC friends. Bosnian hams told me many sad but proud stories from Sarajevo.  Most memorable FN was 1997 event in "Sieben Schwaben"!  Latest ham visit was to 2008 Croatia Cavtat IARU conference.  I retired in Nov. 2006.  I was refree at Moscow WRTC-2010, missed PY.  DL FHN visits almost regular.  USA in 2006 and 2009.  UK more often!

​This is 2017 revision of my CV and I should mention successful 2014 nonsmoker lung surgery. Enjoying Facebook, slow food, samoyed walks, classic music.  Dull it isn't :-)
