R390/390A Information
Chuck Rippel's 390 Page
Jose's
R-390 Page A portion of EB5AGV's Page
A Graph of AGC vs Signal Voltages seems to
have been left out of newer manuals.
A Graph of Carrier Meter vs Signal Strength
also is missing in newer manuals.
Take a look at Rovero's R-392 Page devoted
to the mobile-packaged version of this fine receiver
Take a look at Al Tirevold's R-390
Page Yet another excellent source of info!
Take a look at an Ad
in October 1969 QST offering the R-390A (link no longer active)
