I've recently brought back from the dead a 1967 Arvin #87R59 Leather Cased Radio, then repaired the DC jack and and replenished missing hardware. FM and the MB (Marine Band), sucks on it, as I remembered that they did, even in their hey days. However, AM is a different story. On 1270kHz it was pulling in a pretty progressive classic rock station with much flutter fades. Getting an ID was about damned near impossible, and no other radio that I had here seemed to really get this. Not even the C-Crane Plus radio. Best direction was North / South. Boomer went onto an on-line SDR, with great AM receive, and finally caught the ID as WQTT, Marysville, OH,
