Sailing with the Pirate Surveyors Print E-mail

Last week I went out to the office yard here in Salt Lake City to test some GPS receivers. When I turned on my base radio, I noticed there was someone else already using my favorite radio frequency (461.025 MHz.) I thumbed through each of the 14-frequencies programmed in my radio, there was someone else on every single channel.

How many of these guys can be legit?
It should be easy to figure out. Every 15 minutes all radios are required to broadcast the call sign of the license holder. With the call-sign figured out, you can quickly lookup the licensee on the FCC website: http://wireless2.fcc.gov/UlsApp/UlsSearch/searchLicense.jsp

I pulled out my handheld, and listened to each frequency over the course of the morning. My Morse code is a bit rusty, but I lucked out.

They were all Pirate Stations! How cool is that?

Since each GPS base broadcasts its position every minute, it was pretty easy to get exact GPS coordinates for them. Back in the office I Googled the coordinates, looking up addresses and headed out with my vest and hardhat for an `investigation.'

At each site I chatted up the survey/contractor guys and asked how their equipment was working. "Did they have an FCC license?" At one site, they thought they did, but they did not have a copy of the license on hand. (Later I checked online and found that their license had expired a couple years earlier.)

Two of these sites were using older 25-KHz bandwidth base radios. Had they considered purchasing a narrow-band radio? They had heard of the narrow-banding mess but figured they would never get caught.

From my travels selling equipment in the West, I suspect that more than 50% of RTK GPS users (with 450-470 MHz UHF radios) are sailing the unlicensed or wideband pirate ship.

Why would anyone risk not obtaining an FCC license? Here are some great `Pirate Excuses':
1. I won't get caught, I work in the middle of no-where.
2. I don't need a license, my receiver has less than one watt of output power.
3. The dealer who sold me the system told me I was covered by their license.
4.I will never get caught with a wideband radio because nobody can tell the difference.
5. The cost of an FCC license and complying with the regulations is more than the cost of replacing the radio. Let them take it.
6.I have more important things to worry about. Screw the FCC! 7.
I purchased my radio used and it has the old owner's ID in it.

Each excuse is completely, dead wrong:
1. You are an easy mark for a disgruntled employee, bilge sucking competitor or a whistleblower looking to share 1/3 of the FCC's fine. Are you comfortable turning down every job in a populated place where you might get caught?
2. Anything that emits any signal in the 450­470 range must be licensed. Period.
3. Ask your dealer if they will indemnify you against FCC enforcement actions with a bond.
4. The fine for using a wide-band radio is $16,000 per day. It is easy to tell the difference with a spectrum analyzer, by reading the model number printed on the radio or in most cases just looking at the radio.
5. It costs $5 per month for an FCC license. Less for renewals.
6. Good luck with teaching the FCC a lesson! They hold all the cards. Once you flip the switch and transmit, you have to allow immediate on-site inspections. You will lose any battle you choose to fight.
7. Using someone else's ID has got to be worse than not having one at all!

So you still want to set sail with the pirates? The FCC's navy is trolling for you!

Section 301 of the Communications Act prohibits the "use or operation of any apparatus for the transmission of energy or communications or signals by radio" without a license issued by the FCC.

If you are operating without a license, then you are a pirate. The FCC has an `Enforcement Division' that is specifically charged with finding pirates. When they do, they are authorized to seize your equipment, impose a fine and impose criminal penalties.

The FCC recently said "We are taking aggressive enforcement actions against violators" and they maintain a list of recent violators online to prove it (see transition. fcc.gov/eb/sed/ulo.html) While the FCC may not have sufficient enforcement to patrol all of the air waves--all of the time; if you do get caught, you will really regret it.

I looked through the past enforcement list and tallied up the recent `Forfeiture Orders.' It appears that a fine for most first time offenses of operating without a license would be $10,000. Operating with an expired license might be $8,000.

Did I mention that these fines are `Per Day?' You could easily rack up $50,000 in fines in just a single week. I am not kidding, this is a big deal and has the potential to close a business.

What Can Survey Companies Do to Be Compliant?
Hopefully I have your attention now. Let's build a short checklist of things to do to keep your survey company on the happy side of the FCC.

1 Get a FCC License
This is actually the easiest part. Just find a FCC Licensing company and pay them to setup your license. The license is valid for 10 years and the cost will be about $5 per month.

Depending upon your location, the fee for a new license will be around $565.There are three components to the fee:

The FCC will get about $210 of the total fee that you pay About $110 goes to `Frequency Coordination' service The balance is for the licensing company

While it may be possible to obtain a license using the FCC's ULS online tool without professional help, I have never known anyone to successfully process their own application. Ever.

It currently takes about 5-months for the FCC to process an application however 10-days after your application is submitted you may use the FCC file number as a temporary FCC ID. Carry a copy of the completed application with your base radio as your temporary license.

If you are a dealer and rent systems with radios, your license should have the FCC station class code `FB6T'. If you rent a system, make sure you have a copy of the radio owner's FCC License and that their license has the FB6T code which makes the license transferable when rented.

2 Label Your Transmitter with your FCC Call Sign
This is as simple as writing your call sign on the side of your radio with a sharpie. I personally go all out with my label maker because, well...I love making labels.

3 Keep a Copy of Your FCC License with the Radio in the Field
You are required to have a copy of your FCC License with your base radio when it is operating.

When you receive your license from the FCC, make a copy and put it in with your base kit.

4 Make Sure your Radio is Configured to broadcast your FCC Call Sign
Your radio must broadcast your FCC Call Sign at least once every 15 minutes in Morse code (CW.) If you have a scanner, you can listen for the distinctive tones.

5 Enable CSMA or `Rx Priority' on your Transmitter
Digital data is licensed at a lower priority than voice.

Surprisingly your licensed digital data cannot interfere with licensed or unlicensed voice traffic. Unfortunately this means an unlicensed trucker on the same frequency as your base has priority and you radio has to pause while the trucker illegally talks.

All radios have a `Collision Sense Multiple Avoidance' or `Rx Priority' setting that disables data transmission when voice or other data users are on the same frequency. You have to leave this feature enabled.

You can mitigate many of the CSMA side effects by setting the base radio's sensitivity to the lowest value. This prevents your radio from hearing and avoiding distant users on the same frequency.

6 Don't Keep Un-Licensed Frequencies Programmed in your Transmit Channel Table
It is illegal to have frequencies available for user selection that are unlicensed.

Receivers allow you to have channels with different transmit and receive frequencies. If you use a community base, your radio will need to listen to the CORS frequency, however you won't have a license to transmit on it so don't program the frequency into the transmit table.

7 Make Sure Your Radio is Narrowband Compliant
Since January 2013 all radios must be 12.5 KHz bandwidth or utilize an over-the-air baud rate of 19,200 or higher in a 25 KHz channel. (However you must apply for and receive a special license for 19,200 operation in a 25 KHz channel prior to operation.)

What happens if you get caught transmitting with a 25 KHz Radio at 9600 or 4800 baud? The penalties are listed on page 6 of the FCC DA 13-376 Public Notice:

What are the potential enforcement consequences of unauthorized wideband operation or falsely claiming narrowband status while continuing wideband operation?
Licensees operating in wideband mode after January 1, 2013 (...) are in violation of these rules. Licensees who operate in violation of the Commission's rules or the terms of the licensee's license, or who cause harmful interference to another licensee, may be subject to appropriate enforcement action. Such enforcement action may include admonishments, license revocation, and/or monetary forfeitures of up to $16,000 for each such violation or each day of a continuing violation, and up to $112,500 for any single act or failure to act.

8 Watch Special Regulations When Near Canada
 Your license restricts operation when you are "South of Line A, West of Line C"; about 75 miles from Canada. If you are near the Canadian border use the absolute lowest power setting that will provide coverage for your job.

9 Beware of `Business Band' Frequencies
The frequency coordination of licenses for surveyors results in nearly all new licenses having the same 14-frequencies allocated. These standard frequencies typically have two frequencies that are shared with `Business Band' users:

The `Dot' Business Band (Industrial/ Business Pool) frequencies are in common use by just about everyone, for just about everything. Unless you are really in the middle of nowhere, it may be best to avoid these Dot frequencies.

10 Stay within your Licensed Power
All FCC licenses specify a Maximum Effective Radiated Power (ERP.) Typically your license will allow a 35 watt ERP transmission:

A 35 watt transmitter connected to a `Unity Gain' antenna will broadcast 27 watts. Using readily available `high' gain antennas you can greatly exceed your licensed ERP:

Someone will definitely notice if you are broadcasting 100 watts from your base and the FCC won't like it much either.

You may ask "why anyone would use a high gain antenna?"

If you have a 5 db gain antenna, you can set your radio to 18 watts output and generate a 35 watt ERP while doubling the life of your radio's battery.

So What Should I Do?
When I deliver GPS equipment to a new RTK users they usually ask if I think they need to obtain an FCC license. Let's carefully do the math:

The FCC License Dilemma
Pros: avoid $8,000 to $20,000 per day in FCC fines, the loss of radios plus any attached survey equipment, future inability to obtain a license.
Cons: $5 per month in licensing fees. Yes, I suppose this could be a difficult decision. If you only plan on being in business for the next week.

I very strongly recommend that you follow the `Not-A-Pirate Checklist'! (see PDF) It won't cost much, it won't take long and it reflects positively on both your company and our profession. Good surveying to you!
