| One of the challenges for ham operators is the lack of 1.25-meter radio equipment available on the commercial market. As of this writing there is no current all-mode amateur transceiver for this band. Any all mode transceivers are out of production, and the small handful of current production models are FM only. [[1.25 Meter Ham Radio Transceivers]] are primarily FM mode. | | One of the challenges for ham operators is the lack of 1.25-meter radio equipment available on the commercial market.
