Ref: Your note of Wed, 13 Jul 94 23:40:14 EDT (attached)
Hi Walt,
I just had a note from KJ6TC explaining this. The original IBM PC used
8-bit cards that could be used for IRQ 0-7 only. When the AT-bus was
introuced, they "cascaded" another 8-bit interrupt controller to handle
IRQs 8-15. This controller was attached to the old controllers's IRQ2
line.
In order not to obsolete any 8-bit boards that had to use IRQ2, they
set aside IRQ 9 on the 2nd controller. You can specify IRQ 9 on your
software driver and it will work with an 8-bit card that is jumpered
for IRQ 2. On an AT-bus, IRQ 9 is the way to get to IRQ 2.
Bottom line, you can have an 8-bit card configured for IRQ 2, or
a 16-bit card configured for IRQ 9, but not both. Some older VGA
cards were hard wired to use IRQ 9, but apparently that is no longer
common.

Hi Bob. Thanx for the clarification. What is a cascade interrupt. I have
always been puzzled by this. For some programs setting COM3 to IRQ2 does
the same thing - makes my device communicate with the computer. I have
never fully understood why this is so and why specifying one or the
other interrupt works some times and not other.
To beat an old phrase to death: "Curious minds want to know."

Hi all,
Judging by the info below, it sure looks like contesters might want
to focus their antenna-building efforts on the low bands for the next
several
months. (I know, the low bands have been hot for awhile.) Guess I'll have to
get that 160 -meter inverted L up soon! (Wanted to do it this fall, but
"life"
(and winter) got in the way! HI)
Anyone have any hints to offer to someone trying to get (the
horizontal portion of) such an inverted L antenna up over (across) several
treetops? PSE reply to me directly--I will summarize if there's interest.

Solar activity is extremely low. On six of the past seven days
there were no visible sunspots, and every day the solar flux was
below the average flux number for the previous 90 days. As we are
near the bottom of the solar cycle, don't expect much change. For
the next year we should see many more periods with no sunspots.
For the next few weeks there should be little activity, except for
a possible coronal hole causing geomagnetic disturbances a few days
from now.
Sunspot Numbers for January 11 through 17 were 0, 0, 0, 0, 0, 0 and
11, with a mean of 1.6. 10.7 cm flux was 71.5, 69.5, 69, 69.7,

Can someone give me exact details of the match they used to feed
their Inverted L for 160?
We (N0BSH, WX9E, and I) will be putting up a Inv L for 160 down
at FS5PL for the CQ WW 160 SSB and ARRL DX SSB CONTESTS, and
need to know what supplies to bring down with us.
We will be able to have the vertical part up about 40-50' and the
horizontal part starting there and going to about 20-25' high.
If the length is cut right, do I only need a 2:1 XFMR? Some air-wound
coil and a clip lead tap? I prefer not to bring down an antenna tuner.
How many (read: few) radials can I get away with and at what length?
So, what do you guys and gals use to match your Inv-L????
(Direct replies please.)
Thanks!

Since several folks asked for the "answer" to my question, I'm posting
this to the group. BTW, tnx all for the numerous, helpful replies.
To sum it up in a nutshell, without getting technical:
IRQ2 and IRQ9 are mapped together, and basically link the lower 8 IRQs to
the upper 8. So, you can use IRQ2 or IRQ9, however, you cannot use both,
as they are really one and the same.

it has been my experience that you can't use IRQ 2 on most motherboards...
you have to use IRQ 9, which cascades *FROM* IRQ 2 (not *TO* interrupt
2)... IRQ 2 is not separately available... my advice is to tell the
software that you are using IRQ 9, and set the hardware jumper on the
device to IRQ 2, and if it works, stick with it... if it doesn't work,
then u can tell the software to try IRQ 2...
i just went through this with a logitech bus mouse, which uses hardware
IRQs 2, 3, 4, or 5... if i set the jumper on the mouse interface board for
IRQ 2, i have to tell the mouse driver (in this case, my linux box) to use
IRQ 9... else it doesn't work...

Hi,
My neighbor Tor N4OGW/9 found a bow at a garage sale for $5. He
made a special arrow by taping a couple welding rods along the shaft
and wrapping it in black tape. (Either that or wrapping it in solder, I'm
not
sure which.) He then rigged a fishing reel on the bow. He can shoot the
arrow quite a long ways with the fishing line attached, which can then be
used to pull wires etc. It works great for getting wires over trees!

Hi Glenn,
For my infamous inverted L (refer to my post, 'NAQP SSB or Whhack! ...)
we slingshotted (?) a line over a tree and had a pulley on the end of the
line
for the L wire to go through. We were able to position the wire in the
desired vertical position as well as having the wire be 'free' to move about
to the desired horizontal position. We also used a line through another
tree to get the L horizontally positioned. The slingshot setup was a
Zebco 202 fixed to a "wrist rocket" and a 1 oz. sinker for the weight.
Good Luck,, Roger

I have many pines here, and use them to support several wires. I get them up
there with a fishing rod/reel:
Use 1-2 oz. weight on spincast reel, vertical arc, many tries (just cut off
weight and pull line back for unsuccessful ones).
When finally satisfied with placement of monofilament, tie intermediate
heavier line to end (remove weight), pull it back up and over the tree
toward you (the reel). When can reach it, disconnect intermediate line from
monofilament, tie heavy support line (or the insulated antenna wire if
desired) to the intermediate one, pull it up and over.
Keep your knots compact. I often tape over them to help them pass through
the branches without snags.
I only have to go over one tree at each end for my needs. If you are simply
"laying the insulated wire" across several treetops, you repeat the above
for the next tree, etc.
Long ago my son had hunting bow & arrow setup. I tried to use it, wound up
sticking one of his $5 "pointed" hunting arrows high up in the dam
treetrunk!. Luckily, it fell out by itself, but only after several weeks in
the tree.
I have used the rod/reel successfully maybe 20 times over the years. Not
easy, but it works.
To make sure they stay up, I have started using small wire rope (like the
winch cable you see, only smaller) as guy wire. Very reliable.
My trees vary from 50 to 75 feet.

I've been quite happy with using a bow and arrows with monofilament line.
Shoot the line over the tops of the trees and pull a heavier line across
after (be sure to tape the joint, so that it'll slide easily through the
many crotches between branches that the monofilament inevitably drops into).
I have never bothered to try to elevate the antenna wire above the trees,
and never noticed any effect on either transmit or receive.

Hello Glenn,
Lots of guys thought I was kidding them last year at Field Day when I
pointed to some 90-100ft tree and I told them that's where the 160m
dipole will hang from, and we're going to use this tree for the G5RV.
I went to the local department store in the sporting goods section and
purchased what was called a "Wrist Rocket" years ago, can't remember
what this brand was called. Its one of those sling shots that you slip
your hand up thru the hand support. I purchased some fishing line, and
"borrowed" to bolts out of our maintenance department, they were at
least 3/4" bolt (nuts). I taped the two nuts together, tied the fishing
line on to them and up an away! I was always a good shot in
trapshooting, so I asked the guys which fork of the tree they
preferred, BINGO! I tied some light weight stranded nylon string on to
the end of the fishing line and pulled the antenna up in the tree at
the height that I wanted.
This year when it was time to think about getting on 160 I used the
same procedure with the nice 85ft tree in my backyard. The vertical
section of Inverted-L is 85ft, and it really works!
If you can't find one of these sling shots let me know, I'll send you
one. They're only about $6 or 7. They're light weight and they collapse
so you can throw it a suit case or your Field Day antenna kit or
toolbox.

On a similar note...I was putting up a dipole before SS and man was it windy.
When I ran the 450 Ohm line I noticed a large tug from the wind. I twisted the
ladder line about 1 twist per yard and the drag dropped to 1/4 or so.
