AMSAT sponsors a variety of regular events. Here are some of them.
See also AMSAT-NA Awards.
In many areas, local AMSAT volunteers run a net, usually once a week, on a wide-coverage repeater or simplex frequency. The Houston area net is a good example, and is also available via TVRO when a transponder can be arranged. These nets generally feature AMSAT bulletins, and answer many questions from newcomers and oldtimers alike. If you don't hear the net listed, please let me know. Likewise, if you know of an AMSAT net that isn't listed, please let me know so I can add it.

AMSAT nets are also operated on HF to provide coverage of the entire world, and especially North America. These nets are much like the local nets, though they are somewhat more formal and busy. The 15m and 17m nets are inactive until propagation improves.

When AMSAT OSCAR-13 was operational, the AMSAT Operations Net was held at designated times chosen for good coverage. Guest speakers on special topics were scheduled when available.
With AO-13 out of commission, the AMSAT Operations Net is on temporary hiatus.
The ZRO Memorial Technical Achievement Award Program, or just "ZRO Test" was most recently held on AMSAT OSCAR-13. This activity is a test of operating skill and equipment performance.
During a typical ZRO run, a control station will send numeric code groups using CW at 10 words-per-minute. At the beginning of the run, uplink power from the control station is set to match the general beacon downlink strength. This is level "zero". The control operator will send and repeat a random five-digit number, then lower his uplink power by 3 dB (half power) and repeat the procedure with a new random number (level "1"). This will continue to a level 30 dB below the beacon (level "A").
A participating listener monitors the downlink signals till he can no longer copy the numbers. Those who can hear the beacon will qualify for the basic award by copying the code group heard at level "zero". The challenge is to improve home-station performance to a point where the lower-level downlink signals can be copied (levels 6 through A). To date, only one station (Darrel Emerson AA7FV) has successfully copied level "A".
With AO-13 out of commission, the ZRO test is not being held.
