Welcome to the Mid-Atlantic Portable Operator Association!

This site is dedicated to supporting and encouraging portable amateur radio operation, primarily in the mid-Atlantic united States of America.

1st MAPOA NVIS contest is September 30th.

Rules for the Mid Atlantic Portable Operators Association NVIS contest.

Date: 30 September 2017
Start time: 1500 UTC (about an hour after sunrise on the West coast)
End time: 2100 UTC (about an hour before sunset on the East Coast)
Run is 6 hours.

Frequency/Band– 80 meters only; licensed segments between 3.5 and 4.0 mHz

Classes- There are two (2)

  • 1- single op (One operator ONLY, no spotting)
  • 2- multiop/spotting (more than one op OR spotting used)

    Power level is Low, Medium or High:

  • Low is 2.0 watts or less;

  • Medium is 20 watts down to 2.1 watts;

  • High is 200 to 20.1 watts

    QSO points are given for the power used on each end of the QSO.

  • 4 points for Low power (L)

  • 2 points for Medium power (M)

  • 1 point for High power (H)

    Examples : If you make a contact using 10 watts output (M) on your end with a station running 1 watt (L), each station would get a base score of 6 points (4 points for the L and 2 for the M).  This rewards folks who listen for weak stations.  If you make a contact with a station running 100 watts, and you are also, then the base qso points are 2 (1 plus 1).

    FCC regulations, (and good portable power management!) require that every contact be made with the least power required to reliably make the communication. This can vary based on band conditions, but few contests take this into consideration. At least for the first time around, MAPOA’s NVIS contest will recognize this and allow the operator to use the power required to make the contact, with the power level for each contact noted in the log and transmitted to the other station. You would have to change the class as needed to match the power increase or decrease.  If you choose to compete at the same power level for every contact, that’s fine, but you do have the option to reduce power if conditions appear suitable. Operators are encouraged, but not required, to exchange signal reports, and the contest log should not include same.

    Score Multipliers-

    Modes-  Just like Field Day, a voice contact is x1 and any other mode is x2.
    Distance- NVIS is all about LOCAL contacts not DX, so we want to reward working nearby grid squares. Contacts with the same or adjacent grid squares would be x3, 2 grid squares away would be x2, and 3 or more squares away would be x1.

    Fixed or Portable- If you are portable, not using any grid power or any fixed antenna structures not set up for this event only, then you multiply your total score by 1.5. If you are operating from grid power or using a permanent antenna, your multiplier is 1.


    The exchange will be class, power and grid square.

    On CW (using the previous example) this would sound like this –
    “W1BCD W1BCD”
    “W1BCD de W1ABC 1L 1L FN43 FN43 HW? BK”
    “R R 1M 1M FN33 FN33 QSL? W1BCD”
    “R R TU 73 QRZ? DE W1ABC”

    On phone it would go like this:
    “CQ NVIS, CQ NVIS, CQ NVIS from W1ABC, Whiskey One Alpha Bravo Charlie.”
    “W1ABC here is Whiskey One Bravo Charlie Delta, W1BCD”
    “W1BCD please copy One Lima, one lima, Fox November forty Three, FN43, QSL?”
    “Roger, please copy one Mike, One Mike, FN33, Fox November Thirty Three, QSL?  W1BCD”
    “Roger, thanks, and 73. QRZ NVIS from W1ABC, Whiskey One Alpha Bravo Charlie?


    Submit your logs electronically in cabrillo format, together with your scoresheet, either .pdf or native Excel to MAPOA@runbox.com by October 15th 2017. If you are claiming the portable operation bonus, include the street address and/or latitude and longitude to at least 6 digits from which you operated.

    Good luck, one and all, and we hope to hear you on the air!
