This is the question:

Would you swap a Drake r8b for a Collins 51 S1? Why do I ask this?

I have a Drake R8B and a Wellbrook 1530+ antenna, and pick up a lot
ot QRM and noise S5 - 6 so I cannot do DX, I have tried with other
antennas and the result is the same.

I have read in other forums that receivers with valvel are less noiser
and one owner of the Collins 51 s1 says that QRM and noises do not
exist.

Do you think that it is worth swapping it?

Thanks. Any comments are very welcomed

If you hear a noise increase when you attach your antenna (and I am certain
you will), then a RX with a lower MDS wil be of no help.
