OperatorLink: phone browser signals of STOP, HOLD and SLOW

OperatorLink is made by the team that publishes this site. OperatorLink shows STOP, HOLD and SLOW to the jobsite crew, and passes button presses, chat and voice between phones in a phone browser. ^[1] STOP releases every held direction on every phone and shows a full-screen alert to everyone else. ^[1] HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves. ^[1] Holding a move button keeps sending that move to the other phones; if it stops arriving for 2 seconds, they drop it. ^[1] One-tap radio-style calls such as Go Ahead, Copy That and All Clear are sent as chat messages. ^[1] Anyone who joins can take part in a voice call run from the phone browser. ^[1] The person who starts a jobsite shares a link or QR code, and the crew joins from it. ^[1] A jobsite link stops working 12 hours after the first person joins it. ^[1] A jobsite with nobody in it is wiped after 3 idle hours. ^[1] On Android browsers signals such as STOP make the phone buzz; iPhone Safari ignores the buzz. ^[1] The app can be added to a phone's home screen as a standalone app. ^[1] OperatorLink is currently free to use, and no paid plan is built yet. ^[1] It runs in a phone browser with no app install. ^[1] Button presses, chat and voice pass between phones in a browser. ^[1]

Peak PTT: a dedicated push-to-talk radio

The PTT-84G is priced at $229, with a $19.95 activation fee and $24.95 per month for unlimited PTT, with no contracts. ^[4] PeakPTT is described as having sub-300-millisecond latency, no dead zones, no repeaters, and no FCC licensing. ^[4] Peak PTT lists a toll-free number for contact. ^[4] A crew comparing radio hardware can check the coverage and equipment details each option states.

Eartec: hands-free headset communication

Eartec offers two Crane and Lift headset systems: EPak with Lazer-Pro, and PRO16 with Monarch. ^[9] Users can add more crew members to a system at any time. ^[9] The company says it has provided customer support for over 60 years. ^[9] Customers can buy a set, try it, and return it for a full refund if they do not like it. ^[9] A crew comparing headsets can check the named system details before choosing.

How to pick the right Relay alternative

A crew starts with the phones and gear already on site. If the crew wants browser-based signals, OperatorLink shows STOP, HOLD and SLOW to the jobsite crew, and passes button presses, chat and voice between phones in a phone browser. ^[1] If the crew wants push-to-talk on phones and computers, Zello runs on iOS, Android, Windows, and Mac and states a per-user monthly price. ^[7] ^[2]

If the crew wants group voice channels, GroupTalk states that group voice channels allow simultaneous communication across multiple teams. ^[8] If the crew wants dedicated radio hardware, Peak PTT states its PTT-84G hardware and pricing details. ^[4] If the crew wants hands-free headset systems, Eartec states that it offers two Crane and Lift headset systems: EPak with Lazer-Pro, and PRO16 with Monarch. ^[9] For any option, the crew can check what its own phones, equipment, and site conditions support before choosing.

Things to check before you choose

Match the option to the phones and gear on site. A browser-based tool depends on the phone browser and the signal each person carries, so a crew checks that before a shift. Confirm the price each option states covers the needs of the crew, and check what happens after any trial period ends. If the crew needs a visible signal, ask how that tool keeps it on the phone. If the crew works in areas with weak coverage, ask how the tool behaves there. These checks belong to the crew, because the facts on this page do not cover them.
