Hello and welcome!
Your 48-890 is a 1948 model, and as part of Philco's "Tropic" line of radios, was made for export to Europe, Africa, Central/South America and Asia.
The humming indicates failing electrolytic capacitors. You should not attempt to operate the radio any more in that condition.
The AM band (.55 - 1.70 on the dial) is still very active, but there is not as much on the various short wave bands as there was 30 or more years ago.
Please check your private message (PM) inbox - I am sending you a PM about this radio.
