Question:   What is the FCC interpretation of 47 CFR 90.214 concerning transient frequency behavior?

Answer:   The general technical requirements for a transmitter operating in the Private Land Mobile Radio Service Transient Frequency Behavior are contained in 47 CFR Subpart I of Part 90.  The requirements for transient frequency behavior are given in 47 CFR 90.214.  All units that operate in the frequency bands 150 - 174 and 421 - 512 MHz must be tested and reported, but the time interval (T1 and T3) limits of 47 CFR 90.214 do not apply to units with six W or less output power.
