Getting grounded \u2013 at last!<\/h1>\n

By Jock Elliott, KB2GOM<\/strong><\/p>\n

Readers\u2019 comments are among the best things about writing for the SWLing.com blog. When a reader responds to a post and leaves a comment, it does three things. First, it lets the author know that someone actually read the post. Second, it provides valuable feedback \u2013 \u201cI liked it.\u201d \u201cDid you know about this . . .?\u201d \u201cI had a similar experience.\u201d \u2013 and so forth. Finally, it provides the author an opportunity to learn something, and that perhaps is the most fun.<\/p>\n

A case in point: when I posted this<\/a>, Andrew (grayhat) said:<\/p>\n

\u201cIf you want to make an experiment, connect the end-fed to the Satellit high-Z wire input (clamp), then pick a (relatively short) run of insulated wire connect one end of the wire to the high-Z \u201cground\u201d (clamp) and the other end of that wire to the \u201cgnd\u201d hole in the wall plug<\/p>\n

The above being said, I prefer keeping antennas outside and taking care of the feedline, this helps reducing or eliminating noise from indoor appliances like switching PSUs and other things, anyway, if you want, try the above idea and let me know how it works for you\u201d<\/p>\n

To which, I responded:<\/p>\n

\u201cThanks for the comments.<\/p>\n

Thanks to a tree falling on the powerlines, I now know that the inherent electrical noise in my radio room is basically down to the level of atmospheric noise.<\/p>\n

Neverthless, experimenting with a ground is definitely worth trying. A thin wire, sneaked out the window to a ground rod, might do the trick. I\u2019ll report back after I try.\u201d<\/p>\n

Andrew (grayhat) came back to me and said:<\/p>\n

\u201cI was serious, try the \u201cwall plug ground\u201d I described, it won\u2019t start any \u201cmagic smoke\u201d or the like, otherwise, if you can lay out a wire with a length of 5m max, cut to be NON resonant, and connected to a good ground stake, go for it<\/p>\n

Then, if you want to discuss this further, just ask Thomas for my e-mail, I agree to share it with you.\u201d<\/p>\n

Now, I really appreciated Andrew\u2019s comments, but what I had not told him was that there is just one wall plug in my radio shack; it is really inaccessible, and I am not sure I can get a ground off it. Further, the rest of the power \u201csystem\u201d in my shack is a rat\u2019s nest of power bars and extensions, and I have zero confidence that any of them will provide a useful ground.<\/p>\n

But \u2013 and this is a big but \u2013 I did take Andrew\u2019s point: that connecting an actual ground to the ground clip on the back of the Satellit 800 might improve things.<\/p>\n

Two big advantages I have at my shack are that it is on the ground floor, and there are windows right next to the radios. It is maybe eight feet from the back of the Satellit 800 to the ground outside the window. So running a wire from the 800 to a ground rod could be potentially easy.<\/p>\n

I am in the act of researching a source for ground rods on the internet when I am interrupted by the \u201cbrain dudes\u201d in the back of my head who run the filing system. The conversation went something like this:<\/p>\n

Brain dudes:<\/strong> Hey!<\/em><\/p>\n

Me:<\/strong> What?!!<\/em><\/p>\n

Brain dudes:<\/strong> Didn\u2019t you use to have a ground rod out front when you had your ten meter antennas on the roof?<\/em><\/p>\n

Me:<\/strong> Yeah . . .<\/em><\/p>\n

Brain dudes:<\/strong> Didn\u2019t you \u2013 at your Better Half\u2019s request \u2013 pull that ground rod out of her flower bed when you took the antennas off the roof?<\/em><\/p>\n

Me:<\/strong> Yeah . . .<\/em><\/p>\n

Brain dudes:<\/strong> Well, we had a meeting here, and we think you might have put that old ground rod in a corner of the garage. Why don\u2019t you go have a look?<\/em><\/p>\n

Me:<\/strong> Well, if you really think so . .<\/em> .<\/p>\n

Brain dudes:<\/strong> Yeah, we think so. Get going.<\/em><\/p>\n

So I wander out to the garage, and there, in the corner, is the old ground rod. Thank you, Brain Dudes!<\/p>\n

Before I show you what I found, first you need to see what a new ground rod looks like:<\/p>\n

\"\"<\/a><\/p>\n

See! Nice and shiny and bright and wonderful.<\/p>\n

MATURE VIEWER WARNING: scroll down only if you are mentally and psychologically prepared to view what an old<\/em> ground rod looks like.<\/p>\n

Okay, you\u2019ve been warned:<\/p>\n

\"\"<\/a><\/p>\n

Not pretty, not nice, but possibly usable. With some effort, I was able to unscrew the clamp screw and slide the clamp up and down. Next, sandpaper of various grades was applied to the rod in the clamping area to remove corrosion and increase the likelihood that the ground wire might make actual good electrical contact with the ground rod.<\/p>\n

I went outside, hammered the rod into the ground, attached the ground wire, and sneaked (snuck?) it in through the window.<\/p>\n

\"\"<\/a><\/p>\n

With one end of the horizontal room loop<\/a> attached to the red wire terminal on the back of the Satellit 800 and the ground wire connected to the black wire terminal on the 800, I started tuning around the time stations on 5, 10, and 15 MHz and used the antenna switch on the back of the 800 to change between the wire terminal antenna and the indoor end-fed antenna (which is also connected to the 800 but through coax). The indoor end-fed had a stronger, more copyable signal than the antenna connected to the wire clips and the ground rod. Hmmm. Note: both antennas are approximately the same length and are run along the same path in my radio shack; see the original post above.<\/p>\n

But then I tried connecting the ground wire to the appropriate terminal on the LDG 9:1 unun feeding the coax to the Satellit 800.<\/p>\n

\"\"<\/a><\/p>\n

Tah-dah! Instant improvement in the signal. Attaching and removing the ground wire from the LDG unun I could see a clear one-half S unit change when I attach or detach the ground wire. Excellent! So now, the indoor end-fed antenna run through the LDG 9:1 unun with ground wire attached is my go-to setup for the Satellit 800.<\/p>\n

Thank you, Andrew (grayhat), \u201cYou da man!\u201d<\/p>\n

That\u2019s my story, and I\u2019m sticking to it.<\/p>\n","protected":false},"excerpt":{"rendered":"
