05/06/08 07:35 AM Plum Point-Tropo, 462.550 Rptr, .050608 by Doug

This morning tropo is in. On the AIS map I can see ships at Norfolk, VA, and in the Atlantic ocean and the Delaware Bay.

I'm listening to what sounds like an American training vessel of some type using a ship-board repeater with an output on 462.550 MHz. Young people are referred to as "cadet." There are references to Captain, Chief Mate etc.

The antenna used at the moment is a vertical. No bearing. CTCSS detected is 136.5

The more I listened to this morning the more I think it was actually FSI to a GMRS repeater input. The repeater had no control operator and was repeating input traffic.

FSI from a ship using 467.575 and I think the same one is on the GMRS band edge frequency 467.5375. The only ship close to my home at the moment is the

EVER REFINE
Panama
IMO 9061124
Destination Savannah
call sign 3FSB4

There is a mild tropo in effect.

Ship using 467.575 MHz, a repeater input channel of a local family GMRS system. In violation of ITU regulations, international treaty and FCC Part 80.

Ship is meeting a pilot boat in 15 minutes. There are two ships in the Bay at the moment:

The VALGA
from Belize
Destimation St. Petersburg

Ship heard using 467.575 MHz. Tropo is in effect. Based on signal strength adn the location of the directional antenna I suspect the ship is the following:

Bulk Intrepid
Marshall Islands
Desti: Newport News

A vessel is proceeding down the Bay using 467.575 MHz in violation of ITU regulations and FCC and NTIA Rules. It is believed to be one of three ships. Based on signal strength I suspect the first:


Atlantic Conveyor
Sweden
SCKM
MMSI 26601800
IMO 8215534
Cargo Ship

MSC Natalia
Panama
MMSI 352309000

03/26/08 10:07 PM Chesapeake - Plum Point, 467.600 032608,2158 by Doug

There is ship-board repeater using 467.600 as an input channel to a repeater with an output of 457.600 MHz now in the Chesapeake Bay. 467.600 MHZ IS NOT AND NEVER HAS BEEN ALLOWED FOR USE IN US WATERS. The ship is most likely European since this channel is for marine use in Europe.

The following ships are passing Plum Point Point, MD:

MSC Endurance
V7HX3
Marshall Isalnds
Cargo ship
MMSI: 538002326
IMO: 7820849

Libra Corcovado
VRDH5

IMO: 9241463

Swan Ace
C6WV4
Bahamas
MMSI: 309369000
IMO: 9338825

Atlantic Companion (While I cannot confirm I suspect this ship)
SKPE

03/23/08 06:26 PM Chesapeake Bay - Plum Pt. 457.575 American Pirate by Doug

In Calvert County Maryland licensees are currently looking for the source(s) of data (telemetry) transmissions on or about 457.575 MHz. A thorough search of the FCC ULS has produced NO license records for systems capable of this signal strength over such a wide area of the county.

This is looking more and more like a telemetry signal used by a utility company or other company that has to monitor or control flow.

The signals have been heard in two locations, 15 miles apart. Bearings are to multiple locations. Signal strengths are inconsistent with low-power data transceivers that are allowed on this frequency.

The data monitored on a communications monitor is described as: The measured frequency is 457.5725 MHz. It has an idle deviation of 500 Hz and goes to 800 Hz on the peaks every 7 seconds. AFC on an R8500 receiver at the second location measures the frequency between 457.575 and 457.5729 MHz.

AUTHORIZED Part 90 frequencies for this range are:

457.58125
457.575
457.56875
457.5625
457.55625

Output power is supposed to be two-watts or less. These transmitters are way above that level.

The signals are on the air for approximately 55 minutes per event. There is no pattern yet. The following are the most recent time periods:

3/13/08 1600-1445 Thursday
3/18/08 1900-1950 Tuesday
3/19/08 1705-1755 Wednesday

As soon as I can, I'll post an audio sample so others can help us identify the modulation type and hopefully the owner or manufacturer of the devices.

These transmitters can be causing severe interference to ship traffic in the Bay on a frequency AUTHORIZED for international shipping.

We want to protect our visitors from American commercial pirates so the visitors don't move to GMRS inputs out of desperation.

03/23/08 06:06 PM Chesapeake Bay - Plum Point: 467.575, 032308, 1255 by Doug

A ship went by on the Chesapeake today using 467.575 as an INPUT frequency to a ship-board repeater with an output of 457.575. This places GMRS licensees at GREAT RISK of being repeated on an unauthorized radio frequency for the GMRS licensee. The CTCSS tone in use was 146,2. The crew sounded like an AMERICAN crew.

In the last month TWO American vessels, one CIVILIAN and one MILITARY have visited the Bay using GMRS inputs.

The problem of FSI is even broader now. It extends to AMERICAN OWNED and MAINTAINED ship-board radio systems including ones owned and operated by our OWN GOVERNMENT!

No international company has ever responded to our email regarding their ships using our frequencies. Americans don't seem to care despite their training and FCC licenses.

PopularWireless STRONGLY encourages GMRS licensees experiencing FSI to CARE and DO SOMETHING about the problem on your end. Send email, alert the FCC, write your Congressman, identify the ship with AIS and email the owner. This problem is not going away until the squeaky wheel gets good and loud.
