MARCONI WIRELESS of AMERICA - TYPE 101 TUNER/RECEIVER

 
Frequency range:  200 to 500 meters

Description: The type 101 receiver consists of an inductivel coupler with two detectors. It was intended for land stations which used a 5kw tramsnitter. The 101 design was derived from the United Wireless Type 'E' tuner. The 101 used a loose coupler mounted behind the fromt  panel and incorporated two rectifiers - namely, cerusite and carborundum. These were mounted on the front panel. Less than 100 of the 101 tuners were manufactured.
