Re: Topband: How were CQWWDX-CW Test cndx on TB at YOUR QTH?
Thank you very much for trying Luke. I was the 80m op who requested that you try to work K3LR on 160m. Unfortunately, we were not able to complete any 160m QSOs with VK this year. 73, --Kirk K4RO On 11/29/2021 5:33 PM, List Mail wrote: Terrible.

Re: Topband: How were CQWWDX-CW Test cndx on TB at YOUR QTH?
From another peanut whistle from the east coast: Fri night most EU stns were weak and marginal for me even to try...but did any way. Sat night abt the same altho a few had a fair sig...a good bit of QSB both nights. Only worked 4 EU stns, total, and they were stronger than most of the rest heard. No problem working Carib stns (15). The highlight for me was working WH7T & KH7M with ease (1011 & 1041Z 11/28)...both a real 579. And my hats off to the op. at ZM4T (1124Z 11/28) that spent several minutes getting me into the log. Boy, what a patient, first class op...tnx OM. And the setup here was a TS-440S...100W and a inverted L (with a four wire CP), which is covered over with tall pines. Even peanut whistles can have some funwhich I did. 73 de Bill K4JYS Smithfield, NC - Original Message - From: "Wes" To: "topband" Sent: Monday, November 29, 2021 7:02:18 PM Subject: Re: Topband: How were CQWWDX-CW Test cndx on TB at YOUR QTH?

Re: Topband: W1FV 9-Circle Feedline & control Line Chokes?
Rich, I don't use any chokes on my 160m 9-circle RX arraylocated about 900ft from the shack. Chokes on the lines of your antenna couldn't hurt. Snap-on chokes may not offer worthwhile resistance. 8, 50-ft radials each element. "W8JI" elements. No Hi-Z elements. I used his "touch-the-feed-line-to the radial ground" to see if there is any change to the impedance at the antenna. NO changes noted. I used 3/4-wl lines on all elements. RG-6 coax. RG11 to shack. Thru-the-coax remote control. See ON4UN's DXing book for a couple of photos. 73, Charlie, N0TT On Mon, 29 Nov 2021 08:13:48 -0500 (EST) Rich Dailey writes: > Homebrewing a 9-circle vertical array, and I'm looking for opinions > from other 9-circle users on > what chokes you're using on the feedlines (rg-6) at the switch box, > and on the control line.

Re: Topband: How were CQWWDX-CW Test cndx on TB at YOUR QTH?
I operated SOSB 160 from my station in Arkansas. I found Friday evening condx marginal and no EU peak at their SR. Saturday evening was much different. Sigs from EU were gud with a nice peak during EU SR. Also had some nice Asia/Pacific during my SR Sunday morning. Sunday evening about an hour before the contest ended, at my SS, EU sigs were great and JW7QIA was excellent for well over 30 mins. 73 Joel W5ZN On 2021-11-29 14:29, w3...@roadrunner.com wrote: Id give it a 6.5.

Message-ID: Content-Type: text/plain; charset="us-ascii" You can make a feedline choke with snap-on ferrites as follows: wind 4 turns of the feedline through 5 snap-on cores of Fair-Rite part #0431176451. The core has an inner diameter of about 3/4 inch and 4 turns of RG-6 is the limit of what will fit in the core. However, using 5 cores will provide a large total choking impedance (~10 kohm) on 160. A larger core will accept more turns but at significantly more cost for the cores. The advantage of making chokes with RG-179 wound through smaller cylindrical cores is the much lower cost, although it's a bit more work to make these chokes. 73, John W1FV -Original Message- From: Topband [mailto:topband-bounces+john.kaufmann=verizon@contesting.com] On Behalf Of Rich Dailey Sent: Monday, November 29, 2021 8:14 AM To: topband@contesting.com Subject: Topband: W1FV 9-Circle Feedline & control Line Chokes?

The transmitting chokes I designed for KZ1W would also work. They use RG179 on a single 2.4-in #31 core. Table 4 in the transmitting choke "cookbook." The chokes will be most effective if placed at the base of each antenna, with any phasing lines shortened as needed. http://k9yc.com/2018Cookbook.pdf 73, Jim K9YC _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
