Proposed 2m Band Plan Changes

The TASMA Technical Committee is proposing some minor changes in the two meter band plan.

These changes are being proposed in an effort to adjust the band plan to current usage patterns and to maximize frequencies available in Southern California. We are seeing an increase in the use of simplex frequencies as an input to a repeater. Under current FCC and ARRL definitions for this type of activity, the simplex frequency, once tied into a repeater, becomes a part of the entire repeater operation. Some of this activity is being done in portions of the simplex frequencies, where it violates Part 97.

In an effort to better follow the frequency usage outlined in 97.201 and 97.205, we feel that moving some of the simplex frequencies around will allow for better frequency utilization while following Part 97 rules.

Auxiliary use not allowed : 144.0-144.5 MHz, 145.8-146.0 MHz
Repeater use not allowed: 144.0-144.5 MHz, 145.5-146.0 MHz

FCC Rule 97.201: 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.

FCC Rule 97.205: A repeater may receive and retransmit only on the 10 m and shorter wavelength frequency bands except the 28.0-29.5 MHz, 50.0-51.0 MHz, 144.0-144.5 MHz, 145.5-146.0 MHz, 222.00-222.15 MHz, 431.0-433.0 MHz, and 435.0-438.0 MHz segments.

We are proposing reclassifying 4 of the previously designated “packet frequencies” into voice simplex frequencies. This does not mean they cannot be used for packet, just that they are no longer set aside specifically for packet.

We are also proposing reclassifying 3 current simplex frequencies for use for auxiliary stations and adding an additional frequency for cross band repeating.

The net result is no loss of simplex frequencies, a gain of three frequencies for auxiliary stations, and an additional frequency for cross band repeating. The reclassification of 4 frequencies from the packet designation, is mitigated by the fact that they can still be used for packet.

We encourage constructive commentary on these proposed changes.  Please send your comments to  Please be as detailed as possible in your comments.
