Announcing the :

QRP-NE (QRP Club of New England)

    79er SPRINT

When: Each Thursday evening during February, 1995

Modes: CW - Crystal and VFO Control

Freq: ~ 3.579 MHz

Power Level - 5 Watts or less output power

Time: 9:00 - 10:00 p.m. EDT (0200-0300 UTC)

To Call CQ - See below

Exchange - RST QTH NE#X NAME; ie.....579 MA NE46X Harry

Members use QRP-NE number; NE46 and Add X if XTAL control; NE46X
Non-members use Power Level; 4W and Add X if XTAL control; 4WX

 QSOs are cumulative: Work the same station on subsequent Thursdays.

  The 79er transmitter was NE-QRP's first club project. It uses a
  3579.545 kHz crystal to set the frequency. These crystals are used
  in the color-burst oscillator of all color TV sets in the United
  States and Canada, and in other devices as well.

  The 79er event is an on-the-air get-together, not a contest. Last
  year, everyone used homebrew transmitters with colorburst crystals.
  This year, we'll let you upscale VFO users join us, but you can't
  work each other! That's right, if you want to work everyone in the
  contest, you have to use crystal control. Crystal-controlled
  stations append the letter "X" to their calls, such as "KR1S/X."
  Yes, it's legal. VFO-controlled stations work only /X stations;
  /X stations work everyone. We hope this will stimulate everyone
  to build a crystal-controlled transmitter to use during the

Transmitter Reference articles:

In case you were wondering, "79er" comes from 3.579 MHz

Articles abound on building a simple crystal controlled
transmitter for 80 meters. Try the "Universal QRP Transmitter",
page 26 of "Solid State Design " (ARRL), or "The Oner" (Sprat),
or "The Cubic Incher" (ARRL), or "The 79er"/"Colorburst Special"

---------------------- ----------------------

Crystal operating technique is very different !
You had better think twice before touching that key.
Many stations will be sharing a single frequency
and an uninformed or inconsiderate operator could
easily be mistaken for a dope; Or worse.

   Simple rules for the VFO operator.

         Do not call crystal stations on frequency.
         Crystal stations listen way up and down the band.
         Give a crystal station a long call, breaking
         in between, for a reply.
         Crystal stations may have a slow T-R switch.
