: Standard jumpers typically limit the radio to ~23 MHz. Reaching the 10-meter band (28 MHz) usually requires more complex modifications to the band-pass filters and oscillators.

These capacitors form high-pass filters in the receive audio chain. By increasing their capacitance, you lower the cutoff frequency to approximately 80-100 Hz, allowing natural voice fundamentals and low-end richness to pass through. icom m700 mods

Most mods focus on "unlocking" the radio from its 48 factory-programmed marine channels to allow full coverage across the HF bands. Audio Quality Improvements: : Standard jumpers typically limit the radio to ~23 MHz

If you have the , the process is often software-based and doesn't require opening the case: check the Logic Board for jumper

To enable transmit on all covered frequencies (approx. 1.6 MHz to 23.9 MHz), check the Logic Board for jumper
