Toilet paper roll CW key

by OH6DC

Sometimes the call of nature gets so strong that it forces you to QSY from the main transceiver. Therefore it is handy to have another radio station QRV in the toilet. You don't even need any conventional CW key there if you follow these instructions.

Attach two strips of aluminium tape like this. Keying cable is connected with alligator clips.

Put another piece of al-tape on the paper roll.

When the roll is back in its place the al-tapes should almost touch.

Pushing the roll holder towards the wall causes a keying contact.
