IC-AT-140

Companion Antenna Tuner
for
Icom M803 and M802

The companion Antenna Tuner for the Icom M803 & M802 SSB's, necessary for connecting to your backstay, or fiberglass SSB 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-1465 (M803) or OPC-1147N (M802) tuner control cable to supply 13.8VDC, DC ground, and carry tuning status signals.

M803 / AT-140 Antenna Tuner Control Cable

OPC-1465

Designed to connect the M803 to the AT-140 Antenna Tuner, the 10 Meter (30+ feet) OPC-1465 Shielded Control Cable supplies +/- 13.8VDC power and control signals between the M803 SSB and AT-140 antenna tuner. With preinstalled connectors on both ends, the OPC-1465 easily plugs into matching connectors on the M803 and AT-140.

M803 / M802 Flush-mount kit

IC-MB-75

2 Kits may be required:
One kit for M802 Control Head & a second kit for the SP-24 Speaker

Give your M803, M802, or VHF radio a neat professional look by flush mounting the control head and speaker using the MB-75 mounting kit. Simply insert your control head or speaker into an appropriately sized hole, and from the backside attach the left and right clamping brackets and adjust the jack-screw. One kit (two brackets) required for each mountable device.

Legacy SSB Accessory Kit Configurations

M803/M802 RFI Kit

Now with Superior RF Choking

Kit configuration designed to suppress common-mode RF interference (RFI). Connects between an Icom M803, M802 & an AT-140, 141 tuner. No soldering required.

Can also be fitted onto coax cable connecting XCVR to AT-120/AT-130 tuners

RFIK-8

The M803 RFI kit is the first step toward reducing / eliminating ship-board Radio Frequency Interference caused by "Common-mode" signals from your SSB radio transmissions. The M803 / M802 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 need an FCC-issued ship station license or MMSI, see the DockSide Radio FCC Licensing page, which links to SeaTech Systems' current licensing service.

Kit contents:

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

Metz Antennas are no longer made. GAM Electronics makes a great DSC Antenna as an alternative.
