SARL National Field Day Contest

The South African Radio League Die Suid-Afrikaanse Radioliga

 

The SARL National Field Day

1. Aim
To work as many stations in Southern Africa as possible on all the HF amateur bands
(excluding the 60, 30, 17 and 12 m bands). In doing so, to learn to operate in abnormal
situations in less than optimal conditions. A premium is placed on developing skills to meet
the challenges of emergency preparedness as well as to acquaint the public with the
capabilities of Amateur Radio.

2. Date and Times
2.1 08:00 UTC (10:00 CAT) on Saturday 13 March to 06:00 UTC (08:00 CAT) on Sunday 14 March 2021
2.2 08:00 UTC (10:00 CAT) on Saturday 11 September to 06:00 UTC (08:00 CAT) on Sunday 12 September 2021.

3. Frequencies and Modes
3.1 HF amateur bands, excluding the 2, 630, 30, 17 and 12 metre bands.
3.2 Phone, CW and any digital mode that can send the exchange as indicated in rule 7.
3.3 Phone, CW and Digital modes on a band are considered as separate bands.
3.4 A station may be worked only once per band under this rule.

4. Entry Categories
4.1 Class A – Field Station, Multi operator. Such stations must be located in places that are
not regular station locations and must comply with the requirements of a field station as
defined in the general section of rules. A single licensee or trustee for the entry is responsible
for the group entry. All equipment (including antennas) must lie within a circle whose
diameter does not exceed 500 metres. All contacts must be made with transmitter(s) and
receiver(s) operating independent of commercial mains power.
4.2 Class B – Field Station, Multi operator, QRP. All contacts must be made using an output
power of 5 Watts or less. Other provisions are the same as Class A.
4.3 Class C – Field Station, Single Operator. Such stations must be located in places that
are not regular station locations and must comply with the requirements of a field station as
defined in the general section of rules. All equipment (including antennas) must lie within a
circle whose diameter does not exceed 500 metres. All contacts must be made with
transmitter(s) and receiver(s) operating independent of commercial mains power.
4.4 Class D – Field Station, Single Operator, QRP. All contacts must be made using an
output power of 5 Watts or less. Other provisions are the same as Class C.
4.5 Class E – Ultra Light Portable. Light weight self-contained stations, operating QRP or
low power such as RaDAR, Summits on the Air, Parks on the Air (game and nature reserves),
Islands on the Air, Heritage sites, etc. The operator must carry the entire station, antenna
included, to the operating site. The distance carried must not be less than 1 km.
4.6 Class F – Backyard Stations. Such stations must be located in the garden and must

comply with the requirements of a field station as defined in the general section of rules. All
equipment (including antennas) must lie within a circle whose diameter does not exceed 100
metres. All contacts must be made with transmitter(s) and receiver(s) operating independent
of commercial mains power.
4.7 Class G – General Stations. Stations operating from permanent or licensed station
locations using commercial power.

5. Call signs
Only one call sign per station is permitted. In the case of multi-operator stations using more
than one transmitter, all operators shall use the same call sign.

6. Establishment of Stations
Equipment for Field Stations may only be set up in the 24 hours prior to the starting time of
the contest. This restriction applies to antennas, masts, towers and transmitting equipment,
but excludes accommodation such as a caravan, tent, etc. Once a Field Station has been
established at a site, it may not move to an alternative site after the contest starts, excluding
Class E stations.

7. Exchange
7.1 The number of transmitters, the Field Day operating class and the Provincial
abbreviation.
7.2 The sending of a RS or RST is optional – it has nothing to do with the scoring.
7.3 Examples – A three-transmitter Class A field station in North West would send “3A
NW”; A general station using a single transceiver located in Cape Town would give the
following exchange “1F WC” and DX stations are logged as “1F DX”
7.4 Each QSO claimed for competition credit must include contemporaneous direct
initiation by the operator on both sides of the contact. Initiation of a contact may be locally
or by remote. Contemporaneous = existing at or occurring in the same period of time and the
operator must be in control of all the processes. In plain English – a live, air breathing radio
amateur must be at both ends of the QSO.

8. Scoring
8.1 Scores are based on the total number of QSO points x the power multiplier x the
number of provinces worked X the class multiplier.
8.2 QSO Points:
8.2.1 Each QSO with a station from one of the South African provinces and six neighbouring
countries counts five points.
8.2.2 Each DX contact counts for one point.
8.3 Power multipliers (for Class A to F):
8.3.1 Power 5 watts or less x 6
8.3.2 Power 50 watts or less x 4
8.3.3 Power 100 watts or less x 2
8.3.4 Power greater than 100 watts x 1
