Pressing on power on/off would cause radio to come on for two seconds then off

I had similar problem with my S350. It was a component which had failed. I found a place that fixed it at a reasonable cost. It is ACT Electronics in Long Beach, CA. I don't have phone number but you can google it. It is run by a person from India. You send him the radio with a $30 check. He then assesses what is wrong, gives you a price to fix it, send him a check, then he fixes and sends you the radio. He did a fine job for me. Good luck!

Need power circuit diagram for S350 grundig radio

You will need to contact Grundig for this, but really doubt they will supply it unless you are a repair shop that that is authorized to repair their equipment.

When I turn the radio on, it has a good signal strength, as shown by the icon. After about 10 seconds, the strength icon disappears and so does any reception.

most likely there's a defective component (like leaky capacitor). it could be 'toast ' if you can't replace said component

Looking for inexpensive shortwave antenna for

Simple wire can make a great antenna, and it's relatively inexpensive. I've had the best shortwave and AM reception thus far using a long loop (actually a rectangle) of copper wire as an antenna (but folks shouldn't try a loop with some radios designed for use with powered antennas without inserting an appropriate capacitor in series). If you do try wire, you would want to try to make the loop shape as large as possible, and connect the ends of the wire to your radio's antenna connectors.
