Topband: K9AY Loop Proximity to Structures

When I put up my K9AY loop, it was convenient to do so at a location in my back yard where I already had a stub of tubing (from a defunct birdhouse) protruding above ground.  I didn't think about it before this, but that puts the northeast lobe to Europe going through my house at a distance of

Re: Topband: K9AY Loop Proximity to Structures

Pete, I live in a residential neighborhood (not the most dense by any means), and all my receive antennas will point towards my house or a nearby neighbor's house. There are certainly buzzes and whines in parts of 160M that are accentuated in some directions on some RX antennas and not so much in

Topband: CQ160M contest last year and this year

I was looking over last year's results to get in the mood for next weekend. Calliope, the muse of epic poetry, must have been in the area because limericks began flowing. Here you go...if you aren't mentioned, perhaps you will make the post-contest version... 73, Doug K1DG --- Last year ZM and

Re: Topband: K9AY Loop Proximity to Structures

Pete, in my previous QTH the pole of the K9AY was in the corner of my house, both loops partly running alongside the walls. I had good nuls in all four directions and Iworked 230 dxcc on topband. Kees, PE5T Verzonden vanuit Mail voor Windows 10 Van: Tim Shoppa Verzonden: zondag 24 januari 2021

Re: Topband: K9AY Loop Proximity to Structures

I had  the K9AY loop in my back yard at my old QTH in Spring, TX. I quickly learned to orient the loop for noise reduction (had a noisy strip shopping center about a half mile due east) rather than signal strength. The North loop aimed through the house (about 20' from the house) but I could st

Re: Topband: K9AY Loop Proximity to Structures

Pete, The end of my 160 meter tx antenna, an inverted L, was only 7 meters away from the top of the K9AY. It was absolutely necessary to detune the inverted L during listening on the K9AY. I did it by switching it off (floating) with a fast vacuum relay at the feed point. Without detuning the

Topband: RG6 recommendations

After a period of inactivity, I set out to get my station going again. The Beverages were not working with very low signal levels and I replaced 600 foot RG6 feedline from shack to Beverage switch in the woods with new RG6 which still had the plastic wrap around the spool. I was surprised when t

Re: Topband: RG6 recommendations

Hi Charlie, What you see in your TDR sweep of the RG6 is absolutely normal. I've seen exactly the same thing. The rise in apparent impedance with distance is caused by the loss in the cable. If you had a lower loss cable, the TDR trace would be flatter. As long as you don't seen any signif

Re: Topband: RG6 recommendations

Did you re-calibrate your analyzer for 75 ohms? ( rather than 50 ohms ) If no re-cal, then what you see is normal. 73 Lloyd - N9LB -Original Message- From: Topband [mailto:topband-bounces+lloydberg=tds@contesting.com] On Behalf Of Charles Stackhouse via Topband Sent: Sunday, Januar
