Overview
The Zodiac M-5026 was a citizens band (CB) mobile transceiver produced during the 1970s. It represents a crystal-controlled design with full channel capability in a compact mobile format.
Technical Specifications
| Parameter | Specification |
|---|---|
| Channels | 23 channels (crystal-controlled) |
| Frequency Range | 26.965 – 27.255 MHz |
| RF Power Output | Approximately 4 watts |
| Frequency Control | Crystal-controlled (plug-in transmit and receive crystals) |
Physical Description
The M-5026 is a mobile radio housed in a compact metal chassis designed for vehicle installation. The front panel includes a channel selector, volume, squelch, and RF gain controls, along with a signal meter and microphone connector.
The unit uses multiple plug-in crystals to achieve full 23-channel coverage. It is designed for 12 VDC operation and includes connections for an external antenna and speaker.
History
The Zodiac M-5026 was produced during the period when 23-channel CB radios were standard but some models still used crystal-controlled circuitry rather than synthesized designs.
Like other Zodiac-branded radios, the M-5026 was likely manufactured in Japan by an OEM supplier and imported for sale under the Zodiac name.
Legacy
The M-5026 represents a later-stage crystal-controlled CB radio, illustrating the complexity of designs that used multiple crystals to achieve full channel coverage just prior to the widespread adoption of synthesized CB equipment.
