The Problem:

There's no practical way of plugging earphones into the M803. Earphones are an important noise reducing tool, letting off-watch crew rest/sleep, and enjoy their time off.

's Solution:  - Icom SP24-03 speaker

  •  - Headphone / Off-the-shelf ear-bud connectivity - Works with Apple, Samsung,  Google, Huawei, etc., earbuds, or other low-Z (4Ω-8Ω) earphones.

  •  -  Improved speaker sound quality.

Let crewmembers Sleep
Plug your headphone into the M803

DockSide Radio restores the earphone /  headphone connectivity to the Icom M803 with the newly customized SP-24-03 speaker with 3.5mm earphone  jack and  speaker / headphone switch.



Earbud jack + Speaker



Battery Voltage Booster

Ensure your M803, M802, Ham Radio, or other downstream electronics, get the required
13.8 VDC to function properly.

Mounts next to your SSB main unit. The Battery Voltage Booster compensates for both the normal voltage drop  throughout your battery's discharge cycle, and wiring losses.
