Operating Tips

Tactical Calls and FCC Identification

Tactical calls are efficient and convey functional or location information important during an operation.  However the use of tactical calls does not excuse the operator from compliance with the FCC identification requirements [97.119].  The amateur call sign of each operator must be announced at the end of each contact and once every 10 minutes in the extremely rare event that a single contact is longer than 10 minutes. This can be done efficiently. For example:

Station 17: Tom 87 this is Station 17
T87: Tom 87
Station 17: Report to Tom 01 at the joint command post and await assignment
T87: Copy; N6MDC
Station 17: W6LMT

Providing the FCC call sign in this manner complies with Part 97 and indicates that the exchange is complete and others can use the channel.

Club Licenses and Individual Identification

We use club station licenses for our club stations and the various city and county organizations, including RACES organizations.  The ability to obtain appropriate vanity call signs also aids in identification of the organization.  Examples are W6LMT, W6TPD, N6RPV, K6RPD, K1OES and even K6CPT.  However club licenses do not convey operating privileges.  This is especially important on HF (including our 10 meter frequencies), but is still relevant to our other nets.  Therefore the operator should identify with his/her primary license call sign in addition to the organization’s club call sign when opening and closing a net and during periodic formal identifications.  Again this can be done efficiently; example:

This is W6LMT, net control station for the Los Angeles County Operational Area Disaster Communications Service, Lomita District.  Net control operator is Tom 2, N5DQ.
