Dear Colleague ,
I successfully obtained to a Sony CRF-230 device, but unfortunatelly 3 important parts are missing.
These are the timezone table, worldtime disc and SW frequency distribution table.
Regarding that I’am a member of Radiomuseum.org, I saw, that you also have this type of radio.
Please kindly help me out with a scanned copy about them, in original proportion ( maybe also with
A good photo), so I would be able to substitute my shortages!
Thanks in advance,
STS
