Icom AT-140


Companion Antenna Tuner
Icom M803 and M802

The companion Antenna Tuner for the Icom M803 & M802 SSB, necessary for connecting your M802 to your  backstay, or 23-foot or 17-foot vertical antenna. Two cables are required to connect your AT-140 to your M803 / M802; a coaxial cable to carry the radio signals to/from your antenna, and an OPC-I465 (M803) or OPC-1147N (M802) tuner control cable to supply 13.8VDC, DC ground, and tuning status signals.

Super Battery Booster

Battery voltage can fluctuate  between 11 and 14+ vdc. The Battery Booster supplies your SSB and other electronic equipment (when wired downstream) with the  13.6 - 13.8 VDC  it needs
as your batter
y voltage drops


Your SSB must be supplied the proper  DC voltage if it's to perform correctly. Mounted inline between  your SSB's main unit and the vessel's batteries, the Battery Voltage Booster compensates for both the normal voltage drop  throughout your battery's discharge cycle, and wiring losses.

M803/M802 RFI Kit

Now with Superior RF Choking

Kit configuration designed to connect to Icom M803 & M802 with AT-140 tuner

RFIK-8 The M803 RFI kit is the first step in the process of reducing/eliminating ship-board Radio Frequency Interference caused by "Common-mode" signals from your SSB radio transmissions. The M803 RFI Kit consists of two genuine FairRite XLType-31 snap-on RF chokes (for installation on the OPC-1465 Antenna Tuner control cable), one Line Isolator (installs inline with the coax cable), a PL-258 double male UHF Coax Connector, and instructions.

Note: RFI Kits contain components required in a properly designed SSB radio system. Adding them to an existing installation should help reduce interference to other ship-board electronics caused by your SSB. They are NOT, however, a substitute for proper SSB system design. Neither are they a remedy for poorly functioning antenna and RF ground systems.

M803/802 DSC Antenna Kit


Digital Selective Calling is discussed in detail on pages 15-42 of the M802 Instruction Manual.

DSCK-803/802 calls?
What's connected to your DSC antenna connector? If you have an unused coaxial antenna connector on the back of your M803/802 the answer is nothing.  

The Icom M803/802 is actually two separate receivers inside one box; the regular SSB receiver for standard SSB communications, and a dedicated Digital Selective Calling (DSC) receiver. It is this second DSC receiver that continuously listens for DSC calls addressed to your MMSI number (the number you've programmed into your M803/802). If you don't have an FCC-issued MMSI number already, DockSide Radio can file for one on your behalf - see FCC Licenses on this web site, or call 941.661.4498.

Kit contents:
  1. METZ WEFAX/DSC antenna with mounting angle bracket. (Mounts similar to VHF whip).
  2. 30-feet  RG8x coaxial cable with soldered PL259 connectors on each end.

Because the outcomes of using non-standard compromises are in many cases indeterminate, DockSide Radio is unable to provide no-charge technical support to self-customized SSB systems that violate generally accepted industry design practices and basic physics.
