How to File Your FCC 601 Application in Spectrumwatch

APCO uses a computer program called Spectrumwatch to process FCC 601 radio license applications and submit them to the FCC. Following are step-by-step instructions to help you setup a free account with Spectrumwatch, navigate the system, and submit your FCC 601 application to APCO:

1. First, go to www.Spectrumwatch.com

  • Click on Register for a Free Public 601 Account and fill in the required fields. Spectrumwatch will send you your log-in information by email.

 

2. Once you have received your log in information, return to www.Spectrumwatch.com and log in.

 

3. The first page you will see when you log in is the Tools tab. Spectrumwatch provides some helpful tools and information here. This is also where you will create your application with two options: 1) Create New Form 601 or 2) Create Application Based on Call Sign.

 

4. If you need to obtain a new license, then choose Create New Form 601. If you want to modify an existing license, then choose Create Application Based on Call Sign and enter the call sign at the prompt.

 

5. After you create your application, Spectrumwatch will take you to the first page of the application package: the Spectrum Request page. Use this page to choose your Coordinator, Frequency Band/s, and provide Billing Information/Payment. NOTE: MAKE SURE YOU ‘SAVE’ EACH PAGE BEFORE MOVING ON TO THE NEXT PAGE.

 

6. On the Spectrum Request page, also make sure to click the checkbox ‘Click this box if you have read the terms and conditions’ about halfway down the page.

 

7. Use the Tree View, Table View and Bulk Tasks menus on the left-hand side of the page to navigate through the pages of the application, going in order from top to bottom. This is especially important when adding new locations. To add new locations, start by adding the sites under the Locations section; then add the transmit antenna(s) under the Antennas section; then add the frequency(ies) under the Frequencies or Bulk Add Frequencies sections; finally add the emission designator(s) under the Emissions or Bulk Emission Tasks sections. If you are modifying existing parameters, simply go right to that section.

 

8. If you have comments to add, attachments to include, or want to print or PDF a copy of the application, use the Notes, Attachments, or Print Preview icons at the top of the page and on the sliding menu at the right-hand side of the page.

 

9. When your application is complete and you are ready to submit it to the frequency coordinator, click on the Notify button at the bottom of the left-hand menu and follow the prompts.

 

10. You can use the My Account tab to track your applications (My Apps) and manage your Spectrumwatch account (Account Management).

 

If you find the process of completing the forms yourself to be too complicated and need assistance, our Licensing Services department will be more than happy to help you.

Bandwidths:

a) Occupied bandwidth: The frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers radiated are each equal to 0.5 percent of the total mean power radiated by a given emission.

b) Necessary bandwidth: For a given class of emission, the minimum value of the occupied bandwidth sufficient to ensure the transmission of information at the rate and with the quality required for the system employed under specified conditions. Emission useful for the good functioning of the receiving equipment as, for example, the emission corresponding to the carrier of reduced carrier systems, shall be included in the necessary bandwidth.

1. The necessary bandwidth shall be expressed by three numerals and one letter. The letter occupies the position of the decimal point and represents the unit of bandwidth. The first character shall be neither zero nor K, M and G.

2. Necessary Bandwidths: between 0.001 and 999 Hz shall be expressed in Hz (letter H); between 1.00 to 999 KHz shall be expressed in KHz (letter K); between 1.00 and 999 MHz shall be expressed in MHz (letter M); between 1.00 and 999 GHz shall be expressed in GHz (letter G).

2 Bandwidths for radiolocation stations in the 420-450 MHz band and for stations operating in bands subject to this footnote will be reviewed and authorized on a case-by-case basis.

3 Operations using equipment designed to operate with a 25 kHz channel bandwidth will be authorized a 20 kHz bandwidth. Operations using equipment designed to operate with a 12.5 kHz channel bandwidth will be authorized a 11.25 kHz bandwidth. Operations using equipment designed to operate with a 6.25 kHz channel bandwidth will be authorized a 6 kHz bandwidth. All stations must operate on channels with a bandwidth of 12.5 kHz or less beginning January 1, 2013, unless the operations meet the efficiency standard of §90.203(j)(3).

4 The maximum authorized bandwidth shall be 12 MHz for non-multilateration LMS operations in the band 909.75-921.75 MHz and 2 MHz in the band 902.00-904.00 MHz. The maximum authorized bandwidth for ultilateration LMS operations shall be 5.75 MHz in the 904.00-909.75 MHz band; 2 MHz in the 919.75-921.75 MHz band; 5.75 MHz in the 921.75-927.25 MHz band and its associated 927.25-927.50 MHz narrowband forward link; and 8.00 MHz if the 919.75-921.75 MHz and 921.75-927.25 MHz bands and their associated 927.25-927.50 MHz and 927.50-927.75 MHz narrowband forward links are aggregated.

5 See §90.259.

6 Operations using equipment designed to operate with a 25 kHz channel bandwidth may be authorized up to a 22 kHz  bandwidth if the equipment meets the Adjacent Channel Power limits of §90.221.

NOTE: The actual emission that should be added to the license application is the emission designation as listed on the equipment’s type acceptance.  This information should be available in the technical specifications for your radios as listed by the manufacturer.
