26 January 2017
Date and Time
21 Aug 2017 1400 – 2200 UTC (Partial eclipse begins at about 1600 UTC in Oregon ends at about 2015 UTC in South Carolina)
To generate observations of propagation by the Reverse Beacon Network (RBN – http://www.reversebeacon.net/), PSKReporter (https://pskreporter.info/), WSPRNet (http://www.wsprnet.org), and event logs before, during, and after the eclipse on the amateur bands for the purpose of ionospheric sounding.
160, 80, 40, 20, 15, 10, and 6 meter bands
60, 30, 17, and 12 meters will not be used.
CW, PSK31, RTTY, Phone
Note: WSPR QSOs are not considered part of the SEQP and therefore may be made during the SEQP on any band. Bonuses are given for operation of WSPR receive nodes. See bonus section below. SEQP participants are strongly encouraged to respect band plans and keep WSPR frequencies available for WSPR operations.
- All transmitting and receiving equipment used to make contacts must be no more than 1 km apart.
- RBN nodes can be any distance apart.
Categories (listed separately in the results)
- Single-operator (one transmitted signal permitted at any time)
- Multioperator (one transmitted signal per band and mode permitted at any time)
- Call “CQ CQ TEST DE [your call] [your call] K” using a single code speed, baud, or bit rate during the transmission. This maximizes the ability of the automated receivers to decode your transmission.
- Send the call sign of receiving station, signal report in RST format, six-character grid locator (e.g. EM48ss), and call sign of sending station. To find determine your grid square, visit http://www.arrl.org/grid-squares.
- The strength (S) value of RS(T) signal reports should represent the approximate peak S meter reading. (Readings greater than S9 should be sent as S9.) A signal report of 599 or 59 is acceptable for any QSO.
Example exchange: If NØAX responds to a CQ by W1AW, NØAX receives “NØAX 579 FN31PR W1AW” and sends “W1AW 589 EM48SS NØAX”.
Score = Multipliers x QSO Points + Bonus Points
- 2 points for CW or Digital; 1 point for phone
- Multipliers: 4-character grid squares counted once per band.
- Bonus points earned (see Bonus Points section)
Duplicate contacts are allowed after 10 minutes have elapsed since the previous QSO with that station.
- Log Date, Time, Band or Frequency, Mode (CW, RY (for RTTY or PSK), or PH), both call signs, signal report sent and received, grid locator sent and received. 6-character grid locator is preferred, but 4-character grid locator is acceptable.
- Use any software that supports the Solar Eclipse QSO Party. Links to SEQP compatible software will be available at http://www.hamsci.org/seqp. Any logging software that supports the ARRL VHF contest exchange format can also be used.
- Include station power level, 6-character grid square, antenna type, equipment list, and extra comments in the log soapbox. Please use the example format for easy post-event processing.
SOAPBOX: power=100 W, grid=FN20Vt, antenna=dipole, equipment=IC7410, SOAPBOX: comments=Totality was beautiful!
Log and Score Submission
- When submitting logs use the Cabrillo format standard.
- Cabrillo format logs may be submitted by following instructions at http://hamsci.org/seqp.
- Operated during totality – add 100 points.
- Operate outdoors (so you can see the eclipse) – add 100 points
- Operate at a public venue – add 100 points
- Provide detailed station operation information – add 50 points each:
- Antenna design characteristics (orientation, E and H plane patterns, height above ground
- HFTA terrain profile. See K6TU service at http://www.k6tu.net/?q=TerrainProfiles. It is not necessary to be a subscriber to K6TU.net.
- Ground conductivity (estimated from online conductivity maps, see https://www.fcc.gov/media/radio/m3-ground-conductivity-map
- Station Effective Radiated Power relative to a Dipole (ERPD) on each band.
- Operate a wideband RBN, PSKReporter, or WSPRNet node during the contest
- 50 points per band and mode (including 60, 30, 17, and 12 meters).
- 50 points per band for providing the I/Q data file after the event by following instructions at http://hamsci.org/seqp.
- Multiple receive sites may be claimed, provided receive sites are spaced at least 100 km apart.
