This is a Marine Direction Finder made by Bludworth Marine of NY, NY. It tunes from 280 KHz to above 510 KHz on a large round dial. The 285 to 315 KHz is marked in red for Marine Beacons. It copies AM or CW. The model is a DF 1028 Standard Arrow. The serial is 4287. I can find no dates on anything. I would guess it is in the 1940s somew - that is a guess - it might be older than that - tubes like 6SK7 and VR105. The loop is balanced (center tapped) and I just hooked up a pre-amp and used my selective voltmeter to copy aircraft beacons and some of the BC band at the lower end. I could get good nulls out of the loop, about 25 to 30 dB and could sometimes completely seperate two station on the BC band on the same freq. I did not power up the unit, as the power supply cables are really brittle and old and I have no info on this unit at all. I thought the power supply might be a vibrator, but it is a dynamotor - see pic. The unit runs off 6 volts DC. It is a heavy duty device - case is cast and loop material is all copper. The loop is 18" in diameter and the whole thing stands 35 inches high. The base cabinet is 14 inches wide and 12 inches deep.. The directional scale under the loop is 9 1/2 inches in diameter and calibrated in degrees. The scale can rotate to make it line up with North. The scale looks nice.
