Radio Regulations and Operating Rules (Austrian Theory AM)
What you must know
Every licence candidate must master the legal framework: the ITU Radio Regulations, the Austrian Telecommunications Act (TKG) and the implementing ordinance on amateur radio, the class privileges of the Austrian licence classes, the frequency bands and their permitted power levels, the call-sign structure (prefix OE, district digits, suffixes for special stations), identification rules, third-party traffic, and the ban on broadcasting and on commercial use. Know the definitions of amateur service and amateur-satellite service, the meaning of primary and secondary allocation, and the obligation to avoid and resolve interference.
Typical traps
Questions love the difference between "must" and "should": identification intervals, the duty to give way on secondary bands, and the fact that a licence is personal and non-transferable. Another trap is confusing CEPT guest-operation rules (short-term operation abroad without a separate licence) with the requirement to carry proof of licence. Band-edge questions test whether you know that emission must stay inside the allocated band, and that power limits refer to peak envelope power for SSB and mean power for other modes.
Worked example / rule of thumb
A candidate on a secondary band hears a primary-service station on the same frequency. Rule of thumb: the secondary user must not cause interference and must accept interference, so the correct action is to change frequency, not to argue priority. Equally useful: identify at the start and end of a contact and at least every ten minutes during it; remember the ten-minute rule and apply it mechanically.
Exam technique
Read the exact wording of legal questions twice; distractors are usually true statements that do not answer the question asked.
