Module-based transmitters accept a removable RF module that handles the radio link, and a synthesized module lets the pilot select an operating channel rather than relying on a fixed crystal. This category covers RF module offerings for hobby radio systems.
What a Synthesized Module Offers
The listing here is the Hitec synthesized RF module. A synthesized design is convenient at a busy field because a channel can be chosen on the module itself, which reduces the need to keep a drawer of individual crystals for each frequency. That flexibility makes it simpler to move to an open channel when several pilots are flying at once.
Module-based systems were a long-running approach in hobby radios, letting one transmitter serve on different frequencies by swapping the module rather than the whole radio. Because module compatibility depends on your transmitter, it is worth confirming that your radio accepts this style of module before ordering.
See the module listing above for the current option.
