Marine Receiver – Skanti R5001

Dear Sparks,

under request of Radio Officer Sandro VIALE (Italy) and thanks to details supplied by him below a short review of one of the most popular marine receiver the Skanti R5001, this receiver has been produced also under Sailor and Debeg:

This is a marine receiver covering 0.01-30 MHz. It receives AM, USBl LSB (BFO), CW, and RTTY, and is a very good performer, especially using AM and on medium- and long-wave.
The R5001 marine and general purpose receiver is designed for use in a marine main radio station. The receiver has synthesized operation in the frequency range 10 kHz to 29,999.9 kHz.

The receiver is designed for reception of type F1, A1, A2, A2H, A3, A3H, and upper-sideband A3A, and A3J signals. It is fully transistorized, and widespread use is made of integrated circuits. These features, in connection with the fact that no crystal ovens are used, cause the receiver to be ready for operation immediately after having been switched on.

Depending on the power pack installed in it, the receiver can be powered from a 24 V battery, or from AC voltages normally occurring in practice.

The dimensions match a 19-inch standard rack.
