This is part of a project to create a control panel for the 28ASR. The panel will control 2 transmitters and also an external reperforator. The reperf switch will select either the main loop for traffic or an internal, "mark-hold" loop to keep the reperf from chattering (running open). In this video, we test the switch for the reperf using a bench supply. We then build a dedicated loop supply for the reperf mark-hold loop. We then install the loop supply into the ASR and test it! And finally we wire up and test the "Standby" feature of the ST-6 for use when transmitting.
