300 ohms for an HF radio?

For many reasons I doubt that.

Common balanced impedances are 150, ~450 and I have seen a few 600 Ohm
RF devices.

300 would be extreme to the limits.

What type receiver is this?

It is a Realistic DX-160. I had this model as a kid and saw the DX-160
on eBay near by and bought it.

The stuff I've seen on it indicates a 50 Ohm input impedence.

For the fun of it I will remove my 4:1 matching transformer between the
coax and the reciver connections and connect the coax right to the
screw terminals and see what happens.

Thanks

That's weird I didn't notice any difference in radio reception at all
between the straight coax feed or thru the 4:1 matching transformer.
