Topband: Preamp Placement?

[David Harmon]

 My loop has an amp located at the loop but the sig at the radio was waaay down.I added a DXE broadband amp at the operating desk to get the sigs back to parity with my vertical.An internal preamp in a modern radio might do the trick but even though I have a TS-890 I have not tried the preamp with the DXE amp shutoff.

 Haven't seen much in the way of public replies to this, so hope that 
you've got some private ones.

For a small mag loop, I'd use the preamp at the loop, especially if 
your feed line is coax.
