Who may be the control operator of an auxiliary station?

  1. AAny licensed amateur operator
  2. BOnly Technician, General, Advanced, or Amateur Extra class operators
  3. COnly General, Advanced, or Amateur Extra class operators
  4. DOnly Amateur Extra class operators
Why Section 97.201 defines an auxiliary station as one transmitting communications point to point within a system of amateur stations (links, remote bases, repeater control links), and it limits control operator privileges to holders of Technician, General, Advanced, or Amateur Extra licenses. That list is simply every class still being issued plus the grandfathered Advanced, which means the only class excluded is Novice. Auxiliary stations also must operate on 222.15 MHz and above, except for certain 431-433 MHz and 435-438 MHz restrictions.
Watch out The choice saying any licensed amateur is the trap: Novice licensees, though very few remain, are specifically barred from being the control operator of an auxiliary station.
Auxiliary station control op: everybody except Novice.

47 CFR 97.201 Auxiliary station.

(a) Any amateur station licensed to a holder of a Technician, General, Advanced or Amateur Extra Class operator license may be an auxiliary station. A holder of a Technician, General, Advanced or Amateur Extra Class operator license may be the control operator of an auxiliary station, subject to the privileges of the class of operator license held.

(b) An auxiliary station may transmit only on the 2 m and shorter wavelength bands, except the 144.0-144.5 MHz, 145.8-146.0 MHz, 219-220 MHz, 222.00-222.15 MHz, 431-433 MHz, and 435-438 MHz segments.

(c) Where an auxiliary station causes harmful interference to another auxiliary station, the licensees are equally and fully responsible for resolving the interference unless one station's operation is recommended by a frequency coordinator and the other station's is not. In that case, the licensee of the non-coordinated auxiliary station has primary responsibilty to resolve the interference.

(d) An auxiliary station may be automatically controlled.

(e) An auxiliary station may transmit one-way communications.
