Yes, I use one all the time. The problem is usually the receiver,= the Wellbrook will easily overload even the best receivers with broadcast s= ignals as most don't have any front-end selectivity below 1.6MHz. Try a=20= 500kHz tuned circuit between the loop and the RX.

I've got a ALA 1530 Wellbrook Loop, is anyone using one of these for 500= kHz monitoring?, although I can hear NDB's nothing on 500kHz.
