      John, W5UWB, suggested we poll current 222 MHz operators for information
      that might be helpful for those who are potential 222 operators. Sounds
      resonalbe to me. I personally have thought about assemblying a 222 MHz
      station but lets face it securing equipment is not as easy as you might
      think. Also, many of us have no experiecne with transverters.

      Looking at a few websites I see that Elecraft and Down East Microwave both
      manufacture transverters. Are their other? Which would you recommend.

      It appears DEM is in the process of moving... Has anybody tried the XV222 by
      Elecraft. Some of these units are kits, how did the assembly go and tune-up?


      If you operate the 222 MHz bands we encourage you to share your equipment in
      some detail. This would also include amplifiers, antennas etc.

      If you have made 222 MHz WSJT contacts, this would also be of interest to
      members of this reflector.

        One will find M.S. on 222 much more difficult than 144. Randoms seem to work out to 800-900 miles but it takes time usually. Try and run during major and minor showers.

        OOPS - forgot equipment! I am using a DEM 25w transverter 28MHz I.F. and the HF rig being either an FT-920 or TS-2000(x). Antenna is an M2 5wl at 54 above

          OOPS - forgot equipment!
           
          I am using a DEM 25w transverter 28MHz I.F. and the HF rig being either an FT-920 or TS-2000(x).
           
          Antenna is an M2 5wl at 54' above ground. Feed it with 70' LMR-600.
           
          Amplifier is a Lunar-Link LA-12 running 500 - 1500w
           
          All amplifiers, preamps, etc are controlled with a sequencer - by either DEM or LNA Technology.
           
          As an aside, the mic lead from my rigblaster goes to a "PTT breakout" from LNA TEchnology. It routes the PTT out to my sequencer and takes the PTT from the sequencer back into the radio. Thus the radio is placed in transmit mode only after all relays have changed state as controlled by the sequencer.
