I have been spot checking an OTR series for sound quality, and at the beginning of several episodes the announcer has distinctly said "This is General Radio."  This does not appear to be an instance of syndication in which something generic will be said that leads to dead air or a musical interlude that gives local stations time to insert their commercials.  But when I type "General Radio Network" into my browser, nothing intelligible comes up?

Can any of the many OTR scholars and collectors in this group provide some information on this?

Thank you very much,
