[Milsurplus] RBF-3

[Ray Fantini]

I would like to think that I have some small understanding of vintage
mill equipment but every now and then there is something that I have no
idea what it is. On the "bay" item number # 6536851054 is a RBF-3
receiver, it appears to tune between 70 to 90 MHz and is FM, with a
front de-emphasis control and an apparent bandwidth of 75Khz. would
think that it may be a fax receiver or maybe some early multiplex wide
band receiver for several channels at once?
