Re: Topband: 160M EWE Problems Part 2

Hi Mark, I would be curious if you are getting a significant S-Meter reading using the external preamp and testing with the antenna disconnected from the cable? If so, my guess would be that the Ewe pattern is terribly distorted by its surroundings, noise is coupling in from other sources - or

Topband: 160M EWE Problems Part 2

Good Morning! Last night was the second night in a row with nice conditions between the east coast and Europe on 160M.I took the time to get a cup of coffee and spend a few hours comparing the Inverted-L and EWE, and recording my observations. All Inverted-L data was recorded with the Icom

Re: Topband: 160M EWE Problems Part 2

Hi Mark, I modeled your antenna last night, and have some comments. There is almost as much reactance as resistance at the feedpoint of your EWE based on your dimensions and termination resistor, but sounds like that's typical (per the ON4UN low band DXing book). The back null is also not as

Re: Topband: 160M EWE Problems

Good Evening I completely repositioned the EWE today, it's about 70 feet from it's original position and is not pointing at the INV-L.It's pointing towards southern EU. I Verified the feedline was OK, verified the transformer was OK etc. Same results. When listening to an EU station on

Re: Topband: 160M EWE Problems

Bjorn, Tim: Thanks for your comments. I don't have much time to play with the antennas until the weekend, but I did manage to hook up an SWR Analyzer. The analyzer says 1.5:1 at 1820 Kc (35 ohms R). So, there is an antenna out there. A need to clarify that the noise level is the same between

Re: Topband: 160M EWE Problems

Hi folks I would like to add some comments to receiving antennas issue. Any resonant thing (wire, cable, rotor cable tower, TX antenna...) will interact with the RX antenna if they are in the same polarity, different polarity has 27 dB or more of isolation due the polarization itself. The

Re: Topband: 160M EWE Problems

I would like to concur with SM0MDG's comments about receive coax connections. I betcha the OP's system is leaking in at levels way higher than the Ewe actually produces. I know everyone loves to detune their transmit antenna, but there's no way an Ewe should sound noisier than the inverted L. A

Re: Topband: 160M EWE Problems

By the way, there is a thread on 160M Noise Levels that is active. Is the noise that I'm seeing common to what others are seeing? If it is, that means it's not local to me (which doesn't mitigate the EWE issue.) 73 Mark K3MSB _ Topband Reflector Archives -

Re: Topband: 160M EWE Problems

Good Evening Everyone Thank you for all the responses, some public, some private. Since some content overlapped, I’ll post my answers to the group. I replaced the 2K pot with a 1.2K resistor. No change. I disconnected the feedline at the base of the Inverted-L (simulating a relay). No

Re: Topband: 160M EWE Problems

It sounds like you have a problem with either the terminating resistor or the matching transformer. Or, there could be a problem with your switching if you have more than one EWE. There is no reason why a EWE would behave the way you describe unless it is simply acting as a shortened

Greetings fellow Top Band enthusiasts! I'm Mark K3MSB, and I live south of York PA. This is my first time posting to this list. I’ve been licensed for 43 years and got on 160M in November 2014, so this is the start of my second year. Why I didn’t get on TB sooner is a question I keep asking
