Ham Radio Field Day RSVP Website: Radio Counts, a Station Cap, and a Band Line

A ham radio field day breaks when two radios are on the air and six people are waiting for a microphone, or when someone who said maybe arrives mid-contact and expects a chair the control operator already filled. Radios, the seat each operator gets, and the bands you will actually run are set before the first call. The club does not string another antenna because a friend decided to come after the shift grid closed. A maybe does not hold a radio.

You can create a ham radio field day RSVP that fills the operator seats on each shift, records license class, and stops when those seats are full.

Ask what this site will actually put on the air

Walk the site with the station captain before you send the link. Write down how many radios will be on the air, which bands and modes, how long each shift is, and how many people may sit at a radio. If this public window is two HF phone stations, 20 meters and 40 meters, in four shifts of two hours from 10 a.m. to 6 p.m., and each radio seats one control operator plus one second operator, that is four seats per shift. Those numbers are your cap.

A seat is one licensed operator for one shift. Say whether a person may take a second shift. One shift per person keeps the day at sixteen seats instead of eight people on the mic. A visitor who is not operating does not take a seat. Pick that rule and write it on the page. If the tent is small, say how many non-operators may stand behind the tape. Zero is a valid number.

Ask which license class may sit the control chair. On HF phone, a Technician generally cannot be the control operator. General or Extra can. A Technician may sit the second seat only while a General or Extra is the control operator at that radio. Put that in plain words. Collect the call sign and the license class on the form. A first name without a class is not a seat. If you cannot check a class, do not assign the control chair.

Set a capacity limit on each shift, not on the whole day as one bucket. When the 12-to-2 seats are taken, that shift says full even if 4-to-6 is empty. People do not get to "show up whenever" and bump the operator who was scheduled. The mast crew is a different list: four people at 8 a.m. to raise the antenna, capped at the number the captain allows near the guy lines. An operator is not automatically on that crew.

The band line is what the antenna will tune

Write the bands on the page and leave off the ones you are not building. If there is no 80-meter antenna and no VHF radio this year, do not offer those seats. Each operator confirms they can work the band on their shift: 20-meter phone or 40-meter phone. A request for digital, when you did not bring a digital station, should not be a form field. The radio that is in the tent is the station.

If the generator sits a hundred feet from the tent, say so, and keep talk off the operating table.

A guest is not a control operator

If a licensed operator wants to bring a guest, track that guest as a separate yes only if a real seat is still open and the guest's own license class can fill it. An unlicensed guest does not get a reserved chair and does not take the microphone. They may stand behind the tape only if you published a visitor cap. One form, one seat.

Put the weather plan in the captain's words. Rain under the canopy does not cancel the shifts. Lightning inside the distance the club uses, for example eight miles, means radios off and masts down. Name the person who makes that call and how you will tell the next shift not to drive out.

Each shift has a handover. The arriving operator is there fifteen minutes early, and the operator on the chair leaves when the clock hits the hour. A late operator does not extend the previous shift and does not split the chair. Write the clock times: 9:45 for the 10 a.m. shift, 11:45 for noon, 1:45 for 2 p.m., and 3:45 for 4 p.m. Miss the handover and the seat goes to a standby already on site, or it stays empty.

The moment the shift grid is locked

The meeting point is the canopy, with the lot name and a note that the antenna field is not a parking spot. Put the station captain's phone on the page. A screenshot of the invite is not a seat. The captain matches call signs to the grid on the clipboard.

Children who are not licensed stay behind the tape. A youth seat exists only if the captain named a control operator and a number. An unlisted family counts as visitors, and that can already be over the tape cap.

Tie your RSVP deadline to the grid the captain posts. Friday at noon is a practical lock for a Saturday start. After that, a late yes is a call about an empty seat, not a promise of a radio. Keep standbys off the grid and tell them they do not have a shift until you write back. A maybe does not hold a radio.

Export the list the evening you lock: shift, station, control or second seat, call sign, license class, party size, and phone. A ham radio field day RSVP is finished when every chair has a named licensee who can legally sit it, the mast crew is a separate count, and a late car knows whether they are operating or standing behind the tape.
