Janar,

Just to confirm - is 'ull' the short wave or 'ultra' short wave band? If so, you will not be able to adapt the set for FM operation, without significant circuit changes - you'd need fundamental changes to the frequency changer, RF amp, IF amp stages and the addition of a ratio detector at the very least! It would work out cheaper to acquire a FM tuner and play it through the 'gram' or 'pickup' sockets on the radio.

If the set you own is a 'classic,' a rare set which could become collectable, changes to it could damage the value. You might get more information from a discussion forum which specialises in old radios, such as:

Got a picture? -- i'm always interested in old radios. As to helping retune i'll be of no help, but i would hazard a guess that you might have to do some dramatic retooling of the circuitry.

Any idea what kind of program is required to open a *.djvu file?

Delving into datasheets?

It's an extremely unobtrusive browser plug-in , I have it installed...no idea whether it runs on Mac platforms though.

System Requirements:

Pentium processor or above with MS Windows 98,ME, NT Service Pack 6, 2000, XP
64 MB RAM, 40 MB free disk space
256-color or higher display adaptor
Internet Explorer 4.0.2 or later

If it does work for you, I could always try to convert the sheets you like into *.PDF format.

Cheers,

djvu, ACDSee doesn't read it and neither does graphicconverter. Frank, can you point me to the plug-in URL and i'll try it, otherwise i'll take you up on the pdf offer

Hi,

Dave it won't help you but here goes:

LIZARDTECH INC.

I checked it and it seems they don't have a Mac/Unix version yet.

Assuming you use a wideband connection, I should be able to send you largish files, so just let me know what you need.
E-mail me me or whatever you see fit.

I'll transfer it to your inbox.

Cheers,

P.S. Guess you found this type of file on a Russian site?

Hi,

Didn't look hard enough.

From what I recall you still run OS 9.X?

THE MAC VERSION FOR DOWNLOAD.

Cheers,
