This article contains notes on installation of a Roger Beep inside an Icom IC910 transceiver.

Fig 1 shows Roger Beep module with optional connector and enclosed in heatshrink tube. Note the hole cut in the shrink wrap to provide access to the level adjustment pot.
Fig 2 shows the module installed in an IC910.
