The mariner shown here is demonstrating the Lear Model P10A “Learavian” portable receiver designed for marine and aviation applications. The six-tube set could operate form 115 volts AC or DC, or from the enclosed rechargable battery, with a charging time of only 30 minutes. In addition to the standard broadcast band, the set also tuned the 195-415 kHz longwave band and the 1960-5750 kHz shortwave bands for reception of all aviation and marine broadcasts and navigational aids. With an external directional antenna, the set was suitable for radio direction finding.

The accompanying article noted that service technicians operating near yacht basins or airports could investigate the possibility of capturing the installation and repair business represented by the set.

The photo appeared on the cover of Radio News 65 years ago this month, August 1950.
