Currently, there is an ICOM IC-725A (different from the IC-725), which exhibits a severe frequency deviation, with the following symptoms:
Frequency meter testing: When the radio is transmitting at 14.120 MHz, the power meter shows a reading of 10.581 MHz; when the radio is transmitting at 29.6 MHz, the frequency meter readings fluctuate randomly between 3 Hz and 6 MHz.
Comprehensive testing: The radio transmits on AM mode at 14.120 MHz, and using a Motorola R-2210B/HS comprehensive tester, signals were detected at random frequencies of 10 MHz and 14 MHz. The power meter indicated approximately 0.01 W. However, when the comprehensive tester outputs -30 dBm, the radio still cannot receive the signal.
Other conditions: The CR-338 temperature-compensated crystal oscillator had a temperature of approximately 60°C after 10 minutes of operation.
Due to the limited publicly available information about this specific model, it may be difficult to repair it without significant effort.
Due to my lack of technical expertise, there's a possibility that the measurement results may not be accurate. I would appreciate any guidance from experienced individuals.
