Making Frequency Lists and Charts

Making Frequency Lists and Charts
Here is the method we use to make RadioMaster Reports frequency lists and charts. The process is not simple, but it does provide quality results in various formats. Radio frequencies start as handwritten notes, gathered over many years from various sources, correspondence, communicating on the air, monitoring, and other methods. Periodically, these notes are added to lists in text files with…

Periodically, these are added to lists in text files with notes. Text files (*.txt) are then edited in Notepad++, and imported/copy/pasted into Excel and manually formatted (labels, columns, rows) for Chirp import compatibility. Chirp CSV files have a certain number of data fields on each line. The first line has the labels that define the data fields that follow in all the lines of the file. A CSV (Comma Separated Value) file is basically just a text file where each field or entry of the text or data has commas, line feeds, spaces, tabs, or other characters as delimiters. CSV files can be opened/read by spreadsheet or database programs and radio programming software. From Excel, CSV files (*.csv) are exported.

The test CSV files are imported into Chirp. Chirp is connected to various test radios, and these radios are programmed and checked manually (either on the air or into dummy loads). Any bugs found with the programming are fixed, and then updated in Chirp and the radios are re-programmed again with the de-bugged file, and this repeats again as many times as necessary until the programming works perfectly. The de-bugged CSV files are exported from Chirp. These CSV files are uploaded to the RadioMaster site and made available to the public for download.

A completed CSV file is then imported into Excel. The columns, rows, and data are edited, re-sorted, and titles are renamed for concise readability. Any columns that are not needed are deleted. The output is copy/pasted into a web html program and a content manager for web listing as a table on the site. The images are made by screen-capture of tables in a browser and using an image drawing program, which is manipulated and output to a file in *.PNG format. All these are uploaded to the site via a web content management program (wordpress) and either Dropbox or FTP.

  1. Have you folks ever heard of SECURE Phones. These are Spread Spectrum units that operate in the 902-928Mhz ISM Band which is shared with the Ham Radio Service. These units are unDFable, and unScannable, with up to .7 Watts of RF Output. The are available, used on eBay for $25US/Per… … Btpost/AL7AQ

    • Bruce, could you please give a little more info on the SECURE Phones? I haven’t had any luck searching Google or ebay using the info you provided. Thanks

    • The SECURE phones and ISM SS are certainly not immune to DF. They can easily be DF’d with a simple beam antenna or other methods.
      At 0.7 Watts, 900 MHz, they are OK for *extremely short distance* communications; about the same distance as cheapo FRS bubble pack radios, more or less. Also, they are incompatible with the radios most others will utilize in an SHTF communications situation. Some may naively think that is a positive feature. The radio you choose to carry with you for SHTF comms should not just enable you to communicate with your own team, but to monitor and communicate with others on FM VHF/UHF, because that is where most of the action will be. If you want to carry a second radio, be sure it is an FM VHF/UHF backup radio for your first FM VHF/UHF radio. If you want a digital feature, pick an FM VHF/UHF that also has DMR.

  2. One thing never mentioned here is the reality of an EMP… you have a radio put away for that? I will bet not.

    • you will loose that bet because i know of many patriots and militia and preppers who use faraday boxes to store their backup electronics in.

  3. Can Chirp be used to program a Baofeng BF-F8+ radio?

    • Arthur, Yes. Same as the UV-5R. Essentially the same radio, slightly more transmit power.
