Re: Topband: 9 circle array

In general, any metal in the near field of the array will have an effect on pattern. This includes radials under the array. It's hard to predict what the results will be in a particular situation, but it can be modeled in EZNEC or other modeling programs. I've done this in the past and the

Re: Topband: K3 Noise Blanker problem?

This is a normal happening with most noise blankers and strong signals. I'm surprised that you have never experienced this before. I run into this all the time when stations using their noise blanker hear my signal very strong and complain that my signal is in several places. I advise

Re: Topband: K3 Noise Blanker problem?

The K3 has two noise blankers. Likely the image you are hearing is caused by the IF noise blanker. If you turn that one off - and just use the DSP one - you will likely find the image disappears. Whenever possible - if you can deal with a noise just with the DSP blanker - you will be less

Topband: K3 Noise Blanker problem?

Hello all..This AM on 160 meters there was a station CQing on 1.820.6 with a fundamental freq signal strength of S9 on my K3. I also found (with the NB on) that I could hear him Q5 but very weak on 1.810.6 and the same S 0 reading but perfectly Q5 on 1.830.6. I turned the noise blanker

Topband: FW: 9 circle array

When I had my 9 element array going in the early 2000's, I did a receive only version with 20 foot verticals. It worked great and compared favorably with the full size antenna. It is still in place at K9RO in Wisconsin. All elements are active. It is patterned after the W0UN design in

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 -

Thank you. It looks like things have improved. I'll check it out soon. 73, Mike www.w0btu.com On Mon, Dec 7, 2015 at 2:06 AM, Henk PA5KT wrote: > > I am connected to the chat almost all day. > I see most messages related to 160m. Did even not know it was also 40m. > Did that

Re: Topband: Noise levels on 160

Hi Dave, Did anyone respond to you about this? (If I wasn't so busy right now, I would.) But I believe that the answers may be in the searchable archives. http://lists.contesting.com/archives//html/Topband/ http://lists.contesting.com/pipermail/topband/

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

Incorrect date and day. According to NAQCC their annual NAQCC 160m sprint will occur in North America on FRIDAY, 15 January 2016. This can be seen at: http://www.naqcc.info/SprintEastern.txt 72, Charles, W2SH > Date: Sat, 5 Dec 2015 14:49:47 -0500 > From: tsho...@gmail.com > To:
