another band can be used only to work a new multiplier. The 10 minutes period starts when the first QSO is logged on that band. QSO in violation of the 10 minutes
rule should be left in the log and they will be automatically deleted by the Committee
but no extra penalties will be applied. Be aware that an excessive number of
violations may lead to the disqualification of the entry.
e. LOW POWER category entrants can use 100W maximum total output power.
f. It is forbidden the dual-CQ on the same band.
g. For Multi-Operator Multi-TX stations only one transmitted signal per band is
permitted.
5. Bands.
Bands from 10m through 80m, except WARC bands, are allowed according to IARU
Band Plans.
6. Exchange.
 Italian stations will send RST and two letters to identify their province.
 Other stations will send RST and a serial number from 001. The serial number will NOT
restart from 001 on each band/mode except for the Multi-Operator Multi TX stations.
 Multi-Operator Multi TX stations will have separate serial number for each band.
7. Multipliers.
 each Italian province (110) count 1 (one) multiplier,
 each DXCC country (except I & IS0 & IT9) count 1 (one) multiplier.
The same multiplier (country/province) can be counted once and only once for each
band.
The 110 Italian provinces (by call-area) are the following:
 I1: AL, AT, BI, CN, GE, IM, NO, SP, SV, TO, VB, VC.
 IX1: AO.
 I2: BG, BS, CO, CR, LC, LO, MB, MI, MN, PV, SO, VA.

 I0: FR, LT, PG, RI, RM (or ROMA), TR, VT.
 IT9: AG, CL, CT, EN, ME, PA, RG, SR, TP.
 IS0: CA, NU, OR SS, SU
PLEASE REMEMBER that I (Italy) IT9 (Sicily Island) and IS0 (Sardinia Island) are
NOT country-multipliers.
8. QSO/Points
 QSO/HRD with own country counts 0 (zero) point but is good for the multipliers
credit.
 QSO/HRD with own continent counts 1 (one) point,
 QSO/HRD with different continent counts 3 (three) points,
 QSO/HRD with any Italian (I & IS0 & IT9) station counts 10 (ten) point

The same station can be contacted on the same band once on SSB/CW/RTTY but only
the first QSO is good for multiplier credit.
9. Final score.
The Final Score is the sum of QSO/points from all bands multiplied by the sum of
multipliers from all bands.
10.SWL Stations.
Listeners are required to log both the callsign of the station heard and of the
correspondent station. Score is calculated based only upon the station heard using the
same rules as per the transmitting stations. A callsign may appear NOT more than 3
(three) times on each band as a correspondent station, regardless of mode.
