Universal compact form utility for limited data paths
Move more information with fewer characters.
MicroForms (MCForms) is a compact messaging method that allows structured information to be exchanged using a shared form template. By transmitting only encoded responses rather than full text, operators can communicate reports, requests, status updates, and other structured data using significantly fewer characters.
MCForms can be used over any text-based communications path where message size matters, including amateur radio digital modes, packet networks, mesh systems, satellite links, email gateways, and low-bandwidth communications networks.
Important
Encoded answers only decode correctly when both stations have the same current form template, including the same form ID, question order, answer codes, and prompt IDs.
Open the Tool
Fill, encode, and decode MCForms from a dedicated working interface.

View formsLearn More About MCForms
MCForms were first developed and widely used within the JS8Spotter and JS8Call community through the work of KF7MIX. The original documentation remains the best place to learn how the system is established and utilized in those systems.
The primary JS8Spotter MCForms repository is maintained by SITREPNET. MCForms.org may mirror selected forms and host community-developed forms, but it is not the official JS8Spotter repository.
