Hi Folks
I am following the conversation about LOG RX antennas, I understand the pain from a noise city lot on 160m. it is hard. I am using Waller Flag's vertical, since 2006, and horizontal since 2010, however vertical noise is so bad with new solar panels and EV charges , on top of LED lights, that I no longer have my Vertical WF, it is inefficient for a city lot. My HWF is working very well. The reason I started a new tread is what I noticed during the last DX season. The number of KW station on 1840 is growing exponentially. If you have 100 station with 1kW on a small portion of the band, it is equivalent a 100 KW single station. Imagine 500 station, 500KW, My HWF preamp is in use since 2010, my first QSO with my 6xBF981 preamp was XU7ACY, long path (160m CW), from the same city lot, not so noise as it is today. However now with the number of FT8 KW's, and most of them very bad linearity, with phase noise several KHz on each side, my old preamp IP3 is not strong enough as it used to be. I will be back to old NORTON's preamp on my station with new high Q front end. With all the power of 100's FT8 station at the same time, the consideration for a new RX antenna and new preamplifier is raising the bar on overall performance. Any new ideas on high performance preamps for 160m?? We will need it. 73's JC N4IS _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
