You’ve just purchased your first handheld transceiver and have been chatting with both old and new friends around town on the 2 Meter band. There are many different frequencies to choose from, so how do you find an appropriate frequency to use?

FCC Rules
The first thing we need to know are the frequencies that the FCC has authorized for our particular license class. For the HF bands, the frequency privileges depend greatly on the license class of the operator. Above 50 MHz, the frequency allocations are the same for Technician licenses and higher. In particular, the 2M band extends from 144 MHz to 148 MHz. The FCC Rules say that any mode (FM, AM, SSB, CW, etc.) can be used on the band from 144.100 to 148.000 MHz. The FCC has restricted 144.0 to 144.100 MHz to CW operation only.

Band Plans


Knowing the FCC frequency authorizations is a good start but we need to check a bit further. Amateur radio operators use a variety of modulation techniques to carry out communications. Often, these modulation techniques are incompatible since a signal of one type can’t be received by a radio set to another modulation type. For example, an SSB signal can’t be received on an FM receiver (and vice versa). We need to use our authorized frequencies wisely by sharing the band with other users and avoiding unnecessary interference. Thus, it makes sense to have a band plan that divides the band up into segments for each type of operation.

New Orleans, La.; Feb. 4, 2013 – Details are beginning to emerge as to the cause of the Super Bowl power outage. The New Orleans Police Department issued the following statement at 4:15 p.m. local time:

“We have evidence that indicates the stadium’s master electrical control unit suffered radio frequency-based damage early in the 3rd quarter, causing the failure of the control unit, and ultimately the power outage.” Said NOPD Captain Ronald Wick. “While the investigation continues, we do not anticipate criminal charges to be filed.”
