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.

Thanks dxAce
I did some digging and the DX-160 definitely has a low impedance
antenna input.
I was under the impression that it was 300 ohm.
I removed the 4:1 matching transformer that I installed at the reciever
which would bring the input back to about 75 ohms and saw no difference
in the signal so it may not be that important anyways in a recieve only
setup.
Not that I doubted you.
