"It will be held in November 2013 in Lebanon, Missouri." Now I live in St Louis MO and my first question: Where the heck is Lebanon MO? By car it's 150+ miles away from me, down hwy 44, and pretty far from Kansas City, too. Their convention center looks nice, at least. Guess the convention will be convenient... for the 14,000 people who live in Lebanon

"What do you do when using the DX Engineering plate when the bolt (that's never been removed) hangs up in the groove on the plate while your in the middle of walking the antenna up or down?" Happened to me quite a few times with my DXE plate in the 3+ years I've had the antenna. Replaced the bolts several times. Much easier to happen with their 43' verticals than with small verticals, like a Hustler. You do get better with practice. Best to use two people and wait for a calm day.

I lived in about the tallest high rise apartment building in St Louis for many years. Luckily I had a nice balcony on the 18th floor and windows that opened. Radio signals did not penetrate it. I actually spoke (on the air) to a ham who was a main design engineer on its construction years before. He assured me it was VERY well built from concrete and steel beams. I've lived on the south side of the building. You could hear almost nothing from the north.
In such a building you'd probably be best to tape wire along a window or use the metal window frame. Who knows how a loop would work near metal beams hidden in concrete? Or even closer to metal lath in walls?
The trick is to experiment. Yes, a piece of wire out a window may work as well as anything.

You're providing almost no info.
What frequencies and services are you most interested in? Do you currently live in this apartment? Main goal of an apartment antenna is usually to reduce man made noise which is often the major limiting factor. Can you run a simple thin wire out a window? What floor in this apartment are you on? What kind of receiving equipment will you use? If it is a tall building, what is is made from?

eHam Forums / Elmers / RE: How much of a help is 6 DB?

But to condense it: 6 DB = 1 S unit That may have been true 60 years ago. On my TS-850 I came up with an S-unit being about 4.7 dB and only on the middle portion of the scale. Difference between say S-2 and S-3 was much less. And I was only testing on 40 meters where I was trying to get an accurate determination of the performance of my array of phased verticals. S-meters can vary by band or even by frequency within a band according to one article.

Two points about the almighty dB:
Don't let anyone tell you can't hear a one dB difference. My Flex radio is unique in having a lab quality S-meter. I can definitely detect such difference in band noise level. Also, I can adjust my tuner to well under 2:1 just peaking band noise by ear.
As for the difference in about 10 dB, look at the huge differences in the scores of high power and low power stations in the CQWW contest. Even when you adjust for the generally better antennas used by HP vs LP, you have to conclude that HP helps... a lot!
After a lot research years ago, I concluded that a single dB of transmit power helps CQWW scores by several percent.

AXW, Mouser owes you one!
I'm aware of those small-parts sites of course, but I've never bought from them. I don't need much at a time. Here in St. Louis we at least have Radio Shack and Gateway Electronics. I'm inclined to head over to the Mouser site and buy a few assortments.
BTW, just about any shopping cart will allow the user to add and subtract items for awhile, sometimes over weeks.
Off topic, but I have to comment that my son just bought an electronics text from Amazon that was shipped to our house from India in a few days. Cost was dirt cheap, too. Damn if I know how they pulled that off.

All five booming in last night. 183 kHz was rock solid into Missouri for hours with an exceptionally clear channel. I presume 160M was good too. -------------------------------------------------- 162 kHz France. 171 kHz Morocco which uses both Arabic and French 183 kHz Germany in French 189 kHz Iceland 198 kHz BBC

If these kits are too expensive, what's the alternative... building a time machine and going back to "radio row" on Cortlandt Street to pick thru piles of war surplus command sets at $2?
My son, who's never changed a fuse, is now playing with Arduinos and such. What's on the horizon except Shack and Shed?

Nice post Bryan. (the Extra should be a snap for you)
Funny thing: Driving home alone tonight I had the car radio on 530 trying to determine the range of our local traffic advisory station. Those stations do darn well for their extreme low power and tiny antennas. I start hearing weak Morse in the background. It was LYQ from 400 miles away coming in under the St. Louis Advisory Station!
A buck a minute! The audience has to be microscopic at that rate card. But paying that pittance enables egotistical nutwads to brag about their "international radio audience." And plenty of them do that. They also pay to have their books printed via the vanity press. I knew a very wealthy guy, a self-styled political pundit, who did both of those things. He had almost zero followers but he had a radio show and he published books.
I remember WRNO. My, they were loud here. Last year I fixed up a 1938 Zenith table radio that had shortwave and I spent a good part of the evening listening to the Radio Havana's famous ham program that happened to be on.
There. That's my total exposure to short wave broadcasting in the last 25 years.
