So again not much likelihood of interference problems. 73s Tracey G5VU ----- Original Message ----- From: "Warren Ziegler" To: Sent: Wednesday, November 02, 2011 4:30 PM Subject: Re: LF: Re: 8kHz of spectrum FYI the U.S. Experimental license WE2XGR covers 42kHz (460-480 and 493-515) with 1kW ERP and includes cw,ssb and all data modes. No interference problems to date. -- 73 Warren K2ORS
