Shokai NR-25F1, manufactured by Japan 508 code company (according to MITI New Hope Jitugyou Co.).
The Shokai NR-25F1 multiband receiver is a Japanese multiband receiver that was traded as an export receiver thanks to its coverage of the VHF aeronautical communications band.
The portable multiband radio has a leatherette-covered pressboard cabinet. It can be operated from 220 V mains or with four UM-2 batteries.
On the front panel, the loudspeaker grill is located in the lower part, above it, under a cover, the horizontally arranged frequency dials, below it the slider controls for tone, volume and the mains switch. The dial illumination can be activated with a small red push-button.
The push-buttons for the frequency range selection are located on the top of the unit; they tend to get a little dusty and usually need a cleaning after the set has not been used for a longer time period.
On the right face are the slide switches for AFC and battery / mains operation. The lower half of the back can be folded up to access the battery compartment, and the mains cable can be stored in a second compartment.
The reception characteristics are not outstanding, the tuning is coarse and in the shortwave ranges, exact tuning to a station on a known frequency is hardly possible. The strongest international stations can be found, but the frequency marks are too wide to tune a frequency with accuracy.
