Raising the "F" layer?


J. Ken Wirsing <radioguy@...>
 

Perhaps if we could clone enough of those 5 kw indestructable amps,
we could heat the atmosphere before the contest to get the MUF at
a high level. I am thinking if the 5k were aimed into a long wire,
low and nonresonant except at perhaps some useless freq like
4 MHz, we could expend enough energy in the tuner and wire
to heat the atmosphere. Yes, some old light bulbs would do
in the absence of a long wire. I think I could try to load
the gutters on the house.

On a more serious note, I am ready to try PSK on 6m. I am in
Grand Rapids, MI, and give me a freq and date/time.
(Is that within the rules?)

Best 73s to all.

If we was really smart, we'd all be real nice to N3DQU and ask him to get out
his "propagation equipment?" to help us out.

Don,
  You might want to hang on to the rotators.  It is really important to get the azimuth and elevation correct when running that much power on the vertical.

I have been reading about hooking 3-One K amps together, and the use of a
fluorescent lamp for a "broad-band" antenna. I must get in on this! I have a
Gap Challenger Vertical for sale, complete with rotator....Hardware was used
in last year's Field Day...

Hey Don,

I'm glad to see that you have some experience with using a rotator with a
vertical, I need some technical advice.
I've tried using the same setup as you, but mine keeps unscrewing the coax
off my vertical every time I turn the rotator. You got any suggestions on
how to fix this ?

Bernie -

I know you didn't ask me, but I feel I owe you something for your
wonderful suggestions about power combining my radios.

Simply turn the rotator upside down. That way the coax connection
will be tightened, not loosened!

Bernie, you will need to do what I did; namely rotate it only to the right.  That way the coax connector stays tight, and won't fall off.

Now why didn't I think of that guys. Ain't it funny how something that can
seem so complicated, be so simple.

Thanks So Much, & 73,

Bernie,
You just got to use a pair of Vise Grips to turn the PL259 into a sort of
crimp connector.

Yes Bernie...I had that same problem, but I solved it by drilling through
the connector and placing a small cotter-pin straight through to prevent the
unscrewing, thereby allowing the coax to twist. After 4 hours of operation,
the coax had enough twist in it to return the vertical to several previous
headings, thereby giving me a circular polarized signal on any band....

OK Guys, I think with your help, I've got my problem worked out.
Now let me see if I've got this right, I mount my rotor upside down, then
drill the connector and install a cotter pin and crimp the connector with
vice grips for added security, and always make sure I turn the rotor to the
right.
Now, as Don pointed out that the natural twist, after a few hours of
operation, will make the antenna circularly polorized, seems to me like
somewhere that I heard that the folks who talk through them satellites all
use circularly polorized setups, so I'll be able to work PSK31 through the
Birds. Man, I'm gettin really excited about all this, I can't wait to get an
EQSL from the International Space Station !

Thanks & 73,

Hi Bernie,

One important enhancement that has been neglected. Examine your coax to
determine the design characteristics. Should the lettering on the coax
read from the radio to the direction of the antenna, then it is of the
transmitting variety .... lettering reading from the antenna down to the
radio would be the receiving variety ..
although you may use one cable for both functions ... much better to use one
of each design in parallel to optomize both your transmit and receive
capabilites. There is a down side to this ... It is harder to twist
cables in parallel... you may need a surplus prop pitch motor!

Tom,

I've come up with a solution to this problem.
I'm now feeding my vertical with 300 ohm ladder line, and impedance matching
is not a problem, because the 50 ohm feedpoint impedance goes into 300 an
even number of times, so matching is not needed. I use one conductor of the
ladder line for transmit and the other conductor for receive. Pretty slick,
eh ?

Bernie,

Thats a wonderful solution. Submit that to QST for publication under the
header "We don't need no steenkin coax"!
