This is a service manual for the IC-E90 MULTIBAND FM TRANSCEIVER
The document serves as a technical guide for servicing the Icom IC-E90 Multiband FM Transceiver. It covers various regional model versions (EUR, UK, ITR, ESP, FRA) and includes critical safety warnings regarding power connections and RF signal limits to prevent equipment damage or fire hazards.
Key sections include detailed specifications for receiver sensitivity, transmitter output power, and frequency ranges across multiple bands (50 MHz, 145 MHz, 440 MHz). The manual provides inside views of the Logic, AF, and RF units with component identification, along with step-by-step disassembly instructions for replacing internal modules.
| Frequency range (Receiving) | 50 MHz: 50-52, 145 MHz: 144-148, 440 MHz: 430-440 |
|---|---|
| Operating modes | FM, AM (RX only) and WFM (Rx only) |
| Number of memory channels | 555 |
| Frequency stability | +6 ppm max. |
| Usable temperature range | -10°C to +60°C |
| Power supply requirement | 5.5-11 V DC or specified battery pack |
| Current drain (at 8.0 V DC) | High power: 2.0A, Low power: 0.8A |
| Weight (with BP-217/Ant.) | 280 g |
Do not apply an RF signal of more than 20 dBm (100 mW) to the antenna connector as it could damage the front end.
When ordering, include the 10-digit order numbers, component part number and name, equipment model name and unit name, and quantity required.
The rated output power is typically 5.0 W for high power and 0.5 W for low power.
