[HiDARG-MEMBERS] Noise Cancellers - RFI Survival Guide

[Bob]

I am always interested in new antennas!  How big is it?  Can it be stealth?

FYI
I have built a “bow tie” HF antenna for the HF bands. No tuner required. SWR 1.5 or better across all the bands. Prior to installing this antenna, my noise level was consistently S4 to S5. With this antenna, my noise level is rarely above S0 to S1. If you want the technical specification and build info, let me know.

This exchange was very helpful.  I thought my buzzes over HF were just my rig and antenna - yet nothing I did made any difference.  Shut down circuits, solar inverter, even main switch to house and used battery to no avail.  Think I will try the MFJ unit along with some HRD software unless you have developed other thoughts in the interim.
