Field Day 2020

Thanks to all who participated in our Annual Field Day Event! See our 2020 ARRL Field Day Photo Album

Field Day is Amateur Radio's annual exercise and public demonstration of emergency communications response capabilities. Radio amateurs throughout North America participate in ARRL Field Day each year during the last full weekend of June.

To maintain safe health practices during the current COVID-19 pandemic, our club members operated from their own stations to compete for Club Awards and contribute to the total club score.

2020 Field Day - 1795 Total Contacts

2019 Field Day - 338 Total Contacts

Field Day operation starts at 11:00 am PDT on Sat., June 27.

CHAT SET UP (Optional): River City ARCS will use Discord software for online chat among participants during Field Day. Those who plan to join our Discord chat should click here now to join our N6NA Discord Chat Group ( Visit the website and register your call sign as a user ID and choose a password. You may join our N6NA Discord chat group either through an internet browser or you may download the Discord app on your home computer or smartphone. Test it before Field Day and you should be good to go. On Saturday morning June 27th all participants who can should check-in via Discord chat before 10:00 AM PDT.

We may also chat with each other via our 145.25 MHz N6NA repeater, but contacts through the repeater do not count for Field Day points.

OPERATING: For full details and Bonus point rules read the 2020 Field Day Packet. You may contact other stations once on phone, once on CW (Morse code) and once on one digital mode on each band. You must log the other station's correct exchange information for the contact to be valid. This includes the station call sign, the number of transmitters at the site and class of operation, and the ARRL section.

Learn and use the ITU phonetic alphabet (Alpha for "A", Bravo for "B", etc) when needed for clarity, and only ask for repeats of (or provide) information that was not copied correctly the first time.

Your exchange information will include the total number of transmitters you operate simultaneously, your class (class "D" when operating in at home on commercial power or class "E" on 100% emergency power), and your ARRL section "Sierra Victor" (SV for Sacramento Valley). For example, if you operate one transmitter at a time, your exchange for a home station on commercial power would be “One Delta Sierra Victor” on voice or “1D SV” on CW and digital modes, or "One Echo Sierra Victor" or "1E SV" on emergency power.

OBJECTIVE: To contact as many stations as possible on the 160, 80, 40, 20,15 and 10 Meter HF bands, as well as all bands 50 MHz and above, and to learn to operate in abnormal situations in less than optimal conditions. Field Day is open to all radio amateurs in the areas covered by the ARRL/RAC Field Organizations (US and Canada) and other countries within IARU Region 2. DX stations residing in other regions may be contacted for credit, but are not eligible to submit entries.

Each claimed contact must include contemporaneous direct initiation by the operator on both sides of the contact.

LOGGING: You may choose to keep a paper log of your Field Day contacts and exchanges or use a logging program like the N3FJP Field Day Log or the freeware N1MM Logger. If you plan to use the N3FJP software and operate class "1D" from your home on commercial power, you will need to download and install version 6.3 of that software from their website. N3FJP Field Day Log requires a one-time $8.99 activation fee. (Optional): We plan to collect and display our live results in real time via the website. If you are able, we encourage you to register on with your call sign as your login name and choose a password. Once you log onto, refer to the Help Section to set up your internet browser to auto-update your live results every 3 minutes and chart it under our club: River City ARCS with our team name N6NA. We will be working as a Club: River City ARCS as an aggregate team of individual call sign users. We will submit our logs individually and indicate you are a member of a Team N6NA.
