Mackay Radio 3001A Marine Ship's Low Frequency Receiver - pulled from service - $350 - (Baton Rouge, LA)
Note: This is a corrected and updated description. For Sale: A very nice Mackay Model 3001A Ship's Low frequency receiver covering 15 to 650 kHZ. This is a Maritime Qualified Low Frequency Receiver which met industry guidelines for 500 Khz emergency service up until that requirement was no longer used. It sports an amber dial which is clearly visible to the operator but subdued in terms of candle power. During the war, radios that were 24 x 7 operated and had any chance of being visible when the radio room door was opened, were given subdued or opaque dial lenses to protect the ship from German or Japanese spotters.

Some say this is really "Very Low Frequency", I don't know; perhaps the area of 15 to 650 kHZ encompasses both bands. These are very popular in Europe as that region is also used there for their broadcast band. This gave European shipping many shore points to navigate by or to. It also gave the Allies many additional "Emergency Signal" listeners who could report in a distress signal being sent. Even school children could understand what SOS meant ("We are sinking") and soon learned a new one: "SSS" - "the cause of this distress is a submarine torpedoing us". If you like to import projects for the winter months, you might enjoy adding this radio to your activities. The only literature I have ever seen on the 3001A has bee…
