Oh, okay. NOt surprised i haven't run into it then <grin>.

YEah but that's not the only bear in them woods. Room
modes, the room's resonant frequency basically. The bass
sounds tubby unless the air personality is right on the mic, and most cardioid
mics have a bass presence bump when worked close, so you want him sitting at a
natural distance away,
which means then you've got the room modes to deal with.
Most sound treatments for small rooms keep the high freqs
from bouncing around, but mids and lows get "tubby" sounding then.
My control room in the back of the truck, you might see some of these on
www.gatasound.com, especially the view of the 19 inch equipment rack. What I'm
talkign aboutare "bass traps" which in the case of my control room hang at head
level and
higher, with another large one under the console.
Essentially they trab that sound inside. Otherwise, that
control room in that truck would be rather difficult to work in.

YEah I know, we got them around here too. yEt they bitch
and moan next town to the west of us, between us and mEmphis is a speed trap.
Ain't no stinkin' speed trap, they warn
you at each edge of town that speed limits are strictly
enforced. So, you may as well just govern yourself
accordingly and remove foot from firewall and not get a
ticket.

RW> This is true as well.
RW> BTW, this seems to be building up steam at the moment.
YEah I'm not surprised. Conditions seemed rather good for
awhile last night for the contest on 20 meters, I worked
about half a dozen west coast sections and then the band
went to hell, but really didn't open up to the west good for me on 40 meters.
I think in the first 1.5 hours I had 39
contacts, and of those 36 were unique arrl sections, I think I had all the
California sections, Western Washington,
NEvada and ARizona all on 20 meters within the first 20
minuets.
Roy>> I could go there. Of course, I'd miss Fidonet, Rush on Radio and
Roy>> NASCAR on TV, but somehow, I think I could get over that.
RW> I'd miss the FIdonet anyway, or a good baseball game, or ham radio of
RW> course, as well as a lot of audio work <grin>. But, I can play a real
RW> guitar or real piano, no electronics needed <grin>.
Roy> Come to think of it, my shotgun would get more excercise too. Game

YEah so would mine <grin>.

I'm not at all surprised by that one either. I've figured
for years as I think I commented that emp weapons were going to happen sooner
or later.
RW> Take out c3 first before you start with ballistics and incendiary

YEah I wouldn't doubt that one a bit. A communications
service company in Des MOines had a faraday cage room for
testing vhf commercial radio equipment. IT was in the
basement iirc.
Roy>> It should get real interesting in about a month, if they have
Roy>> predicted things right.
RW> YEah, is already piquing the interest of hams who like 10

Roy> Friend Andrew told me about receiving a HDTV signal out of Waco this

Roy> He didn't seem too interested in how atmospheric disturbances caused
Roy> by the sun spots could do that.
I'm surprised, but yeah I guess. Must have been tropo or
something maybe. I remember explaining to a lady in NEw
ORleans about why she had ghosting problems, multipath, etc. Oh there's your
perfect example of the problem of small
radio announce booths, same thing. YOuv'e got the
announcer's direct path to the mic, then others, so you have to deaden the
booth over pretty much the whole spectrum.
Roy>>> There was a spectacular aurora event caused by a CME in 1859 that
Roy>>> could be seen from latitudes further south than normal, worldwide.
Roy>>> If 2012 is expected to be even worse than the major solar event of
Roy>>> 1859, just think of the affects it will have on an electronic age

<snip>
RW>> YEs, the Carrington event iirc. Read a bunch on it. A

Roy>> Mike may be onto to something...
RW> I believe he truly is.
Roy>>> You can see as an example what that would do to the world, by

Roy>>> residents there complain about having to live without the modern

RW> YEp, kinda reminds me of my week on "hospital island" after
RW> Katrina.
Roy> Worse yet, they're also freezing their butts off in the process...
YEah, least N.O. was warm!!!
RW>> YEp, and like you say we'll have some warning, but all that
RW>> infrastructure's still gonna crump. Glad i've got ham
RW>> radio, and can unplug until after the big one then run

Roy>> You'll have to do more than unplug if you want to survive the EMP

RW> Yep, store the gear in its boxes with foil shielding or
RW> something they say.
Roy> A tin shed will do the trick, or a metal trash can with the gear on
Roy> blocks of wood at the bottom. The older electronics under the hood
Roy> of your car should do the same, but I wouldn't count on it.
YEah, and the same for a lot of folks with larger gensets
that have electronic controls, those controls will be toast
to, so say goodbye generator.
Roy>>> As a final note on this, it should be noted that some scientists
Roy>>> are connecting the sun's solar activity with tectonic and
Roy>>> geothermal activity ... that is to say, volcanoes, earthquakes and
Roy>>> (consequently) tsunamis and changes in the weather patterns.
RW>> Have read on that too. Quite a wealth of material if
RW>> anybody's interested.
Roy>> That makes more sense to me than somebody claiming that mankind can

RW> SEquestering it for gradual release as do plants, etc. I
RW> can see some of their arguments too though, too much of
RW> anything is bad for you ya know. Thing is, there's enough
RW> actual science behind some of this that I'm not really in
RW> the skeptics camp. i'm still in information gathering mode
RW> on the subject actually, there's enough good data
RW> collection happened, and happening that I'm not totally
RW> writing that one off. YOu must remember, we've come a long
RW> way in just a couple centuries, both in amount of people
RW> occupying the planet, and our technological sophistication.
RW> I can't say with a straight face that we haven't done some
RW> things to upset some natural cycles and balances.
Roy> Like they say here in Texas, don't drink down stream from the herd
Roy> or in hunting camps over the years, don't piss in the river.
Both sides have their share of spin doctors feeding me
propaganda masquerading as science, which concerns me a
bit. I give a bit more weight to the folks who've done
samples of peat bogs, ice cores and the like, because
changes can be tracked over time and when aptterns are badly bent that can
easily be pointed out, and apparently the last century has sort of badly bent
if not broken some climate
patterns according to some reading I"ve done. MEanwhile i
let the spin doctors spin and basically ignore most of it.
Roy>>> If these causalities are valid, the global changes that so many
Roy>>> have predicted may be ushered in by nothing more than our
Roy>>> friendly, or not so friendly, sun. Certainly, man can do nothing
Roy>>> to change that.
RW>> Indeed this is true.
Roy>>> Having your own energy devices is a good start on survival with
Roy>>> the scenario I've just painted, but you'll also need a means of
Roy>>> feeding your lady and yourself as well...not to mention the dog...
Roy>>> 8^)
RW>> OH yeah there's that, but you can always trade <grin>.
Roy>> Depends(tm) on what you have to trade. Dollars, meaning any
Roy>> currency, won't be worth the paper it's printed on, precious metal
Roy>> will be almost worthless in the face of 'there's nothing I'd trade
Roy>> for your gold' that can keep my stomach from growling.
RW> True enough, but barter labor for food, my skills, etc.
Roy> Yeah, that should work...or lemmee fill your locker with game that
Roy> I've collected while hunting.
There's that too, and though the xyl ain't real mobile I can always set her up
in a stand somewhere with a rifle <grin>.
Then there's trapping, and of course, fishing.

Richard
