Auknar tíðniheimildir á 40m
Fyrir hönd íslenskra radíóamatöra hefur stjórn ÍRA sótt um auknar tíðniheimildir á 40m bandinu til samræmis við ákvörðun World Radiocommunications Conference 2003.
Svar hefur borist frá P&F þess efnis að frá 29. mars 2009 verði radíóamatörum sem operera undir íslenskum reglum heimil notkun á tíðnisviðinu 7100-7200 kHz með sömu skilmálum og í dag eru í gildi á 7000-7100 kHz, þ.e. forgangsflokki 1 og hámarksafli G-leyfishafa 1000 W, svo:
|
Tíðnisvið |
Forgangsflokkur |
N-leyfi |
G-leyfi |
Bandbreidd |
|---|---|---|---|---|
| 7000 – 7200 KHz | 1 | 100 | 1000 | 6 KHz |
Standa vonir til að þetta verði íslenskum amatörum lyftistöng, þar sem 40m bandið er gott DX-band héðan af norðurhjara. Í þessu sambandi er mikilvægt að fara eftir nýja bandplaninu frá IARU Region 1 (en bandplanið í heild sinni má nálgast hér):
IARU Region 1 – 40m bandplan
|
Frequency |
Bandwidth |
Usage |
|---|---|---|
| 7000 – 7025 | 200 | CW, contest preferred |
| 7025 – 7040 | 200 | CW, 7030 kHz – QRP Centre of Activity |
| 7040 – 7047 | 500 | Narrow band modes – digimodes |
| 7047 – 7050 | 500 | Narrow band modes – digimodes, automatically controlled data stations (unattended) |
| 7050 – 7053 | 2700 | All modes – digimodes, automatically controlled data stations (unattended)* |
| 7053 – 7060 | 2700 | All modes – digimodes |
| 7060 – 7100 | 2700 | All modes, SSB contest preferred 7070 kHz – Digital Voice Centre of Activity 7090 kHz – SSB QRP Centre of Activity |
| 7100 – 7130 | 2700 | All modes, 7110 kHz – Region 1 Emergency Centre of Activity |
| 7130 – 7200 | 2700 | All modes, SSB contest preferred, 7165 kHz – Image Centre of Activity |
| 7175 – 7200 | 2700 | All modes, priority for intercontinental operation |
Definitions
- All modes CW, SSB and those modes listed as Centres of Activity, plus AM (Consideration should be given to adjacent channel users).
- Image modes Any analogue or digital image modes within the appropriate bandwidth, for example SSTV and FAX.
- Narrow band modes All modes using up to 500 Hz bandwidth, including CW, RTTY, PSK etc.
- Digimodes Any digital mode used within the appropriate bandwidth, for example RTTY, PSK, MT63 etc.
- *Lowest dial setting for LSB Voice mode: 7053 kHz
Notes
- Amplitude modulation (AM) may be used in the telephony sub-bands providing consideration is given to adjacent channel users. (NRRL Davos 05).
- CW QSOs are accepted across all bands, except within beacon segments. (Recommendation DV05_C4_Rec_13)
- The term “automatically controlled data stations” includes Store and Forward stations.
- The frequencies in the bandplan are understood as “transmitted frequencies” (not those of the suppressed carrier!)
