2. Date and Times
2.2 10:00 UTC on Saturday 14 September to 10:00 UTC on Sunday 15 September 2019.

3. Frequencies and Modes
3.1 HF amateur bands, excluding the 2 200, 630, 30, 17 and 12 metre bands.
3.2 Phone, CW and Digital (PSK, FT8 and RTTY).
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 - General Stations. Stations operating from permanent or licensed station locations using commercial power.
4.7 To encourage more individuals and groups to participate in the National Field Day events, a 6-hour section has been introduced. It need not be for one continuous 6-hour period, but once operation has commenced in the contest, off periods must be a minimum of 60 minutes.

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”

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 contact with a station from one of the South African provinces counts for five points.
8.2.2 Each DX contact counts for one point.
8.3 Power multipliers:
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
8.3.5 The power multiplier for an entry is determined by the maximum output power used by any transmitter used to complete any contact during the event.
8.4 Provinces worked multiplier
The 17th SARL Blue Book
2019 SARL Contest Manual – Blue Book P a g e | 42
8.4.1 A multiplier of one for each one of the 9 South African provinces worked (regardless of band) and one extra for working any station outside of the 9 provinces i.e. DX.
8.4.2 EC – The Eastern Cape (including Marion Island)
8.4.3 FS – The Free State
8.4.4 GP – Gauteng
8.4.5 KN – KwaZulu-Natal
8.4.6 LP – Limpopo
8.4.7 MP – Mpumalanga
8.4.8 NC – The Northern Cape
8.4.9 NW – North West
8.4.10 WC – The Western Cape (including Sanae Base and Gough island)
8.4.11 DX – Used for all others that does not fall in the above group
8.5 Class multiplier
8.5.1 General stations, class multiplier of 1
8.5.2 Field stations single and multi, class multiplier of 3

9. Miscellaneous Rules
9.1 A person may not contact for QSO credit any station from which they also participate.
9.2 A transmitter/receiver/transceiver used to contact one or more Field Day stations may not subsequently be used under any other call sign to participate in Field Day.
9.3 Batteries may be charged while in use. The batteries must be charged from a power source other than commercial mains power.
9.4 All stations for a single entry must be operated under one call sign
9.5 There is no limitation to the number of transmitters or receivers that may be deployed. The use of more than one transmitter at the same time on a single band or mode is prohibited.
