The telegraph receiver's operator would visually observe the bubbles and could then record the transmitted message, albeit at a very low baud rate. [10] The principal disadvantage to the system was its prohibitive cost, due to having to manufacture and string-up the multiple wire circuits it employed, as opposed to the single wire (with ground ...
