About this database:
❏ The nets listed in this database are those that are strictly point-to-point systems, and point-to-point relays.
❏ The focus here is on digital mode nets specifically designed for resilience and able to function without the infrastructure we have been accustomed to.
❏ These are currently active nets designed for emergency communications and training.
❏ To assure accuracy, all nets in the database are periodically audited.
>>> ★ Confirmed nets
>>> ▼ Unable to confirm, but with probable reason why
>>> ◇ Failed to confirm – questionable validity, but we continue to check
>>> _ _ Those with no confirmation symbol are in the process of being checked
❏ We try to confirm each entry where possible. We have found that many web site net lists are not correct, and we generally do not use those for this database.
❏ This is for computer-based digital modes only (not SSB voice or CW).
❏ Nets that utilize the internet are not listed here, nor are hobby, “rag chew”, or phone nets.
❏ Another type of net that is not included here are those that are only activated during a real or potential crisis.
❏ A key purpose of this database is coordination of times, days, and frequencies to avoid interference with other nets.
❏ There are some HF digital mode nets that do not fit into the format used here, or we are unable to confirm, or are questionable for some reason. Those are listed here.

Full Database – Sort by Day, then Time Z
Compact PDF – Sort by Day, then Time Z
❏ TIP – A handy way to do this is print the Compact PDF on one side, and the Time Conversion Chart on the other side of a single sheet of paper.
You can copy and paste into your spreadsheet program to filter and sort for your individual needs. For most spreadsheet programs, you should be able to:
➊ Click on the spreadsheet
➋ Select all (Ctrl-A)
➌ Copy (Ctrl-C)
➍ Open a new spreadsheet on your computer, and click on the top left cell (A1).
➎ Paste the data into the spreadsheet (Ctrl-V)
You will probably be prompted for some import settings by your spreadsheet program.
