And here is that old MW-50, still in service, but now just a backup for the BE. Its serial number is 90954, and it was originally built for operation at 680 kHz. (Is this an old WRKO transmitter, perhaps?) Somewhat unusually, it was also built for an RF line impedance of 75 ohms—50 would be more usual today.
