Ham since 1973, first callsign YU2RVS in 1976, followed by YU2OO, 4N2OO, 9A2OO and finally 9A6C. Work almost exclusively CW, except on VHF/UHF where some SSB is a must. Like HF/VHF contests, building amplifiers and antennas.
Tour guide through the picture:
UP: HM HF PA 2xQB4/1100 (1 500W); MFJ864/GI7b 6m PA/TS590S; 30A PS/E73M stackmatch/HM antenna switch; 15A PS
DOWN: DAIWA CN101L/TS930SAT; T2X control box/HV PS for 6m PA; XV144/HL160
My favourite logger is DXlog by 9A5K, supports more contests than I am aware of. ETM8 keyer is used in daily CW work.
Some photos of my HB amps:
Interior of my HF amplifier. Basic design provided by YU1AW, but the arrengement of components in RF compartment should be wiser - that's on me...Need some refining...Plate voltage is 4 kV DC unloaded.
6m amplifier with single GI7b in test position. Plate voltage 2.5 kV DC unloaded, power output 500W max. Original design by YU1AW had to be modified, since C1 in PI tank had too high starting capacity and consequently 2 turns had to be removed from the coil, resulting in 4.5 instead 6.5 turns. Also, input circuit was changed to "T" instead of YU1AW's original circuit. This is how it looks from above:
On the cover of the RF deck there is another 80x80 mm blower taken from some comp PSU to enhance air flow. Hope it will not melt during a contest
Antenna status at JN73WS:
- Inverted V's on 40&80m, appex at 10 m above ground
- Ground plane with 12 sloping radials on 40 m
- Ground plane for 30 m with 2 sloping radials.
40m gp with inverted V's in background
30m gp on a rooftop
I don't collect qsl cards, but if you need mine - let me know during a qso or via e mail.
Don't send your card via bureau, I don't need it.
In spite of all, I do have my own qsl cards and send them away, hi. If you bureau service is not fast enough, send a card directly to my home address with SAE and 2$ enclosed.
I still have a bunch of my old 9A2OO qsl cards and in case someone needs it, just e mail me.
I don't use LoTW or eQSL, sorry.
Now active exclusively from JN73WS on both HF&VHF.
Sometimes I go portable to JN73XS for VHF/UHF reasons.
Activities from other locations are also possible, and in case of VHF&up qso, correct locator will be noted, as well as appropriate IOTA or CI references in case of island activities.
PS - CW FOREVER!!!
