Alden Introduces FM Facsimile Recorders

Alden Electronic & Impulse Recording Equipment Co., Inc. announces the introduction of a line of FM facsimile recorders designed for use aboard ships or wherever facsimile graphics via FM circuits are desired.

The recorders are available in both lO^-inch and 18-inch-wide versions. Both versions are provided with shock mounts for mobile or shipboard use.

Both recorders operate from FM transmissions over telephone lines or radio circuits with a built-in frequency shift converter for the international F4 standard (1500 Hz black, 2300 Hz white). The recorders are compatible with all HF general communications receivers and incorporate winking light monitors to simplify receiver tuning.

The recorders use Alfax electrosensitive recording paper to provide clean, crisp, odorless recordings which are permanent, will not smudge, fade or darken. A four-page brochure describing the Alden 1100 and 1800 Series of FM Facsimile Recorders is available free by writing to John P. Carlson, Alden Electronic & Impulse Recording Equipment Co., Inc., Alden Research Center, Westborough, Mass. 01581.
