4. General Rules
4.1. Transmitters and receivers must be located within a 500 meter diameter circle. All
antennas used by an entrant must be physically connected to the transmitters by wires
4.2. All categories of entrants are allowed to use packet and WEB clusters.
4.3. Using any IP net for the remote receiving, including web radiostations is
unsportsmanlike and the entry is subject to disqualification.
4.4. Self-spotting is not allowed. Soliciting contacts by telephone, telex, internet, packet mail
during and before the contest is forbidden.
4.5. Using other stations call signs for the following – keeping the working frequency on the
other bands, making schedules, DX-spotting, moving the multipliers to the other bands – is
4.6. Single Operator participants may change bands and modes without restrictions. Only
one signal can be transmitted at any given time.
4.7. Single Operator: Those stations at which only one person performs all of operating,
logging, and spotting functions.
4.8. MOST stations are limited by “10 minutes” rule. Start time is determined on the first
QSO made on that particular band. Only one signal can be transmitted at any given time.
Exception: two signals on different bands are allowed if and only if the station on another
(only one) “multiplier” band picked up a new multiplier. This “multiplier” band should also be
changed on “10 minutes” rule. Contacts, violating both rules, should be shown in the log,
they will neither be counted nor penalized for an entrant, but counted for the station
4.9. MO2T (Multi Op, Two transmitters): A maximum of two transmitted signals at any time
on different bands. Each transmitter may make a maximum of 8 band changes in any clock
hour (00 through 59 minutes). For example, a change from 40 meters to 80 meters and then
back to 40 meters constitutes two band changes. Both transmitters may work any and all
stations. A station may only be worked once per band.

5. Exchange:
5.1 Non-Czech and Slovak stations: signal report + QSO number, starting with 001.
5.1.1 MOST (Multi Op, All Bands, Single transmitter) can use separate serial numbers for
each band or chronological serial numbers.
5.1.2 MO2T (Multi Op, Two transmitters) MO2T (Multi Op, Two transmitters) can use either
separate serial numbers for each band or separate serial numbers for each transmitter.
Each QSO in the submitted log must have transmitter identifier.

6.3 /MM stations are not the multipliers, but worth 5 points for any participant.
6.4 SWL stations must copy one or both exchange numbers, points are scored on
common rules.

7. Dupes
7.1 Dupes are contacts made with the same station on the same band. If the first contact
between stations is valid, dupes have 0 points value. If the first contact is not valid, second
(dupe) contact is accepted.
7.2 Dupe contacts should not be marked in the log. Moreover, entrants are strictly
recommended to leave DUPES in the log file. DO NOT DELETE DUPES!
