The User's Manual: Here

Micheal and me


The switches that I find to be the best for sending Morse code are Lever Switches. They provide feedback by clicking when I press on them and release them. These switches can be found at Zygo Industries

Many users of Morse code use sip and puff switch; this is probably the fastest input method. Unfortunately, I don't have much control of my mouth, otherwise, I would be using a sip and puff switch. Some can be found at Origin Instruments

The speaker for the TandemMaster can be any one of the following:
8-Ohm Mini Speaker, Gigaware™ Universal Speaker for MP3, JVCฎ Ear Bud Headphones (If specified, we could include a speaker with your order.)

If your switch plugs are 1/8" mono plugs, you will need a "Y" adapter to allow you to plug the two switches into the TandemMaster. 1/8" Dual Mono Jack to 1/8" Stereo Plug Y-Adapter
(If specified, we could include an Y-Adapter with your order.)
