Interesting,

Airborne comms went up to 20MHz as evidenced by the upper frequency limit of a lot of receivers, so anything above that frequency will be something different.

The thing in the photo has mountings/catches at the bottom of its front panel of a sort seen on plenty of aircraft mounted equipment, and the dynamotor power supply fits in with period practice for aircraft mounted equipment. This definitely isn't the receiver for the weapon control link, because that would be made much smaller and more robust, and powered by batteries. If this is associated with that system, then it must be the receiver for a back channel returning telemetry information to the plane.

Telemetry receivers in a plane are likely to be for operational use. Telemetry receivers for development use are more likely to be ground-based.
