SARL VHF and UHF Analogue / Digital Contest

N.d.R. - Segnaliamo con piacere questo contest che mostra un forte rispetto per l'attività DX  (e non solo per i partecipanti alla gara, pregasi guardare le frequenze ammesse ed il calcolo del QRB). Anche se tutto è perfettibile e qualche pecca c'è (guardare le regole per gli spot)

The 2011 SARL Contest Manual - Blue Book, Issue 9 Page 33 of 73 VHF/UHF contests should be the test of operator ability and station design and the overriding aim is to get away for the weekend and have fun. But
after that, the aims are:

.         To promote activity on the VHF/UHF and microwave bands.
.         To encourage people to work greater distances than usual by operating portable and/or improve antenna systems
.         To provide opportunities for people to activate or work new grid squares

So head to the mountains and hills and see how far you can work.

The Contest is open to all licensed radio Amateurs in South Africa and neighbouring states. All operations shall be conducted in accordance within the limitations of licensing regulations and, if applicable, the requirements for an educational station registration (e.g. for a ZU to operate at power limits of a ZS on a club station) on condition that, A) the Contest station must be registered as educational station and, B) the operator must operate under supervision of a ZS operator. The rules and spirit of the contest must be respected at all times.

The third full weekend of March and September each year - 19 and 20 March 2011 and 17 and 18 September 2011, from 10:00 UTC [12:00 CAT] on the Saturday to 10:00 UTC [12:00 CAT] on the Sunday. The contest starts and ends at the beginning and end on the hour. Use time signals from a reliable source.


1. Base Station
2. Field Station
3. Club / Multi operator station
4. Rovers
5. 4 hour limited category

These categories are further divided into sub-categories

1. Unlimited - include both digital & analogue operation. "Analogue" would include FM & SSB phone and CW
2. Limited A category - analogue only
3. Limited D category - digital only

Base Station (Single Operator or Multi operator). A base station is the normal home or fixed station. One or more amateurs may operate it as long as they use their own call signs.

Field Station: A field station is a temporary station set up in a caravan, tent or motor vehicle and may erect any type of antenna system. One or more amateurs may operate it but they must use one call sign only. A field station may not use any fixtures e.g. masts and towers permanently erected on the sight, nor may the field station use 220 VAC power from the site. The field station must provide their power e.g. generators and batteries on the site for their radio equipment and computers duration of the contest.

            Stations may use only one site for the duration of the Contest, but may move to shelter within one kilometre. Any greater move requires a scoring restart. Two, or more, stations in close proximity may only participate if the stations are erected and operated entirely independently throughout the Contest. Field stations must make sure the venue will be safe, and they must have the necessary permission to be on the site.
Lightning protection must be incorporated on installations as far as possible. Structures or equipment may NOT be taken to a site within 24 hours be-fore the contest start.

Club or Multi-Operator Stations. A Club or Multi-Op station forms the hub of activity during a contest and could work all five bands at the same time.
Either a club or multi-operator team may operate from a fixed location or a field station as de-sired but all the multi-operators must use a single call sign.

Rovers. Rovers are encouraged as they create a lot more activity and fun.
This category is limited to a minimum of one (1) hour to a maximum of four (4) hours continuous operation from a single location. After four (4) hours the Rover must locate to a new 4-digit grid square and may be scheduled
during any part of the 24-hour session operating from any position, mobile or stationary mobile.

            A Rover must:-

.         activate at least 2 grids to be classified as a Rover
.         must work more than 5 stations from a grid
.         submit his logs else all the contacts made with the Rover will not count for points

The 4 hour Limited Category. This category may start or end the contest at any time but may only send in a log for four (4) hours of operation. This is for stations that cannot operate for the full 24 hours.

Contacts. Contacts must be fully two-way. Stations shall give signal reports as well their location as latitude and longitude or full six digit Maidenhead Locator.

            Operators that participate as operators in a field or multi-operator should not be allowed to make additional contacts using their own call sign. Stations should not be operated under more than one call except in the case where the equipment is normally shared and operated by family members.

            Self-Spotting will be allowed, e.g. you may announce that you are calling CQ on 144,250 on a repeater Frequency or on internet logger.

            No station may be worked twice on the same band, however a station can be worked in both analogue and digital modes on the same band.

            Rover stations can be logged again from a new grid square. (See section for Rover stations)

Exchange. The contest exchange consists of the call signs, signal report and six-digit grid locator. All the exchange information shall be copied at the time of the QSO.

            No points will be forfeited if a non-competing station cannot provide a grid locator, or any other information that may be required.
However, the receiving operator shall receive and record sufficient information to be able to calculate the score.


50,150 MHz CW; 50,200 - 50,250 MHz SSB; 50,250 - 50,300 MHz Digital; 50,350 - 50,400 MHz FM; 51,400 MHz FM

70,090 MHz CW; 70,100 - 70,150 MHz SSB; 70,150 - 70,175 MHz Digital; 70,200 - 70,275 MHz FM

144,100 MHz CW; 144,200 - 144,250 MHz SSB; 144,250 - 144,300 MHz Digital; 144,350 - 144,400 MHz FM; 145,500 - 145,575 MHz FM

432,100 MHz CW; 433,200 - 433,250 MHz SSB; 433,250 - 433,300 MHz Digital; 433,350 - 433,400 MHz FM

1296,195 MHz CW; 1296,200 - 1296,250 MHz SSB; 1296,250 - 1296,300 MHz Digital; 1296,350 - 1296,400 MHz FM

Higher frequencies as per band plan

NOTE: The 70 MHz band is a shared band; please avoid QRM to commercial users.

Band multipliers. The score for each band will be the number of points made on that band multiplied by the number of grid multipliers contacted on that band multiplied by the band multiplier. Each new multiplier shall be clearly marked in the log.

6 m x 3; 4 m x 5;  2 m x 1; 70 cm x 7; 23 cm x 9; 13 cm and higher x 15

Station Multipliers. Field stations and Rovers get a x 1,5 multiplier

Grid Multiplier. Only the first 2 letters and first 2 numbers will make up the grid multiplier, e.g. KG44 is a grid used for the multiplier, so all stations using KG44 is one multiplier. KG44ee and KG44ba are NOT two multipliers. The number of points on a band is multiplied by the number of different grids worked.

. Points are calculated as one (1) point per km to a maximum of 1500 km. All kilometre calculations are to be made using the Maidenhead grid locator system using the "Tinylocator" freeware grid calculator programme.
No other distance calculations will be accepted. Tinylocator can be found via Google. Type-in Tinylocator, then click on Tinylocator to obtain the free program.

            There are no limitations on input power, and no multiplier for low input power (but the operators must stay within regulation limits for their licenses). There are no limitations and no multiplier for alternative power supply e.g. batteries.

            The scores in this final tabulation are the sum of the scores on each band. The scores will be calculated by score for each band (Score achieved * band multiplier).

            Only one scoring contact may be made with a given station on each band per session, regardless of any suffix.

            Cross-band contacts or contacts through repeaters or satellites are not allowed and will be invalid in the contest.

            EME contacts are encouraged, that is the ultimate DX on the VHFand higher bands. Stations working EME can do so, but EME contacts must be logged separate from Tropo/MS contacts.

            A station can submit both logs, one without EME where he will compete against all other contesters, and the EME log where he only competes against other stations doing EME.

Awards and Results. A winner, second and third place will be determined for:-

Single-operator stations
Multi-operator stations
The overall winner will be the station from both categories with the highest score. Certificates will be awarded to the first, second and third placed stations.

Sponsor. Log sheets shall be submitted within 15 days after the contest and can be sent by e-mail to Questo indirizzo e-mail è protetto dallo spam bot, abilitare Javascript per vederlo
