Re: [Elecraft] Long wire antennas MORE

2018-01-11 Thread David Gilbert


There is only a fixed amount of total energy contained in all the lobes 
of an antenna.  You almost definitely did get lots of lobes ... but you 
also got lots of nulls that exactly offset all those lobes.  You just 
never heard the the hams that were in those nulls and they never heard 
you.   Whatever you gain in one or more directions is sacrificed in one 
one or more other directions.  This is basic physics.


More lobes is not necessarily better.  In fact, taken to the extreme it 
is self defeating because a very large number of lobes (assuming they 
were somehow all of equal strength as you stated) begins to approximate 
a unidirectional antenna with no azimuth gain in any direction.


Just for grins I modeled your 700 foot antenna in EZNEC+ and on 20m it 
gave a maximum gain of about 9 dbi in a fairly narrow lobe at 16 degree 
elevation in both directions along the axis of the wire.  It also gave a 
total of 36 other sharply narrow lobes arrayed symmetrically in all 
other directions, each with a gain of about 6 dbi.  Between each lobe 
was a deep null of around minus 10 dbi. This was all at the same 16 
degree elevation angle ... there were literally too many lobes to count 
on the 3D pattern, with lots of lobes and nulls at every azimuth and 
elevation angle.


A simple dipole at the same 40 foot height would have given similar gain 
with a much broader lobe (both azimuth and elevation) in the two main 
directions, but of course without the multiple smaller side lobes.  
Three poles and two perpendicular dipoles would have given better 
overall single band results ... the only advantage of the long wire 
being that it gives a similar pattern along with similarly ugly match on 
multiple bands.

Re: [Elecraft] FT8 on PX3? Logging FT8 contacts on a Mac?

Anyone found a way to log FT8 contacts on the Mac version of WSJT-X?


What on the mac are you trying to log to? The native WSJT-X log file, or an
external logging program?

WSJT-X prompts me to log to the WSJT-X log files after every QSO for FT8,
just like it does for JT65 & JT9. I haven't messed with trying to also
automatically get those log entries into a "real" logging program, but JT
Bridge should be able to do such a thing.

One of the simplest ways is to use HRD at the station; TeamViewer to run the 
station remotely and Skype for audio (I use the SignaLink for that for SSB) 
from a laptop, tablet or smartphone.   (I also run the KAT and KAP utilities, 
so I have complete station control.)

The software is free (after the initial HRD support purchase) and I’ve used

Sorry, a technical difficulty in my mind.  I take a photo of my station 
periodically, usually when I change something.  I found the paddle in question, 
it was somewhat old when it was given to me.  It is *not* a hexkey, it has a 
trapazoidal base, narrower in back.  It does have the "yoke" arrangement of the 
BY-1 but it is more square-ish.  From the photo angle, I can't see if it had 
the spring looped around the post.

I also have a photo of my HexKey from Elecraft and it is *definitely
not* a BY-1 mechanism.  I would still have it, and the $400+ wife spent on the 
ZN-SL single-lever for my birthday, were it not for my decreasing ability to 
manipulate the dual paddle with either hand.  It, and the two BY-1's I still 
have, were/are touchy to adjust.  I never became iambicized so I lost nothing 
going to the SL and regained the ability to send over 25 WPM.

I apologize for the mixup

It's a good idea, but too severely limiting since almost all monitors 
now run on 19V. Thus far the HP 23es is fine. I ran RTTY with it next to 
KPA500 on several bands with no issues. Final test will be pointing the 
6m EME array at the shack and listening. The monitors look really good 
and were on sale at Best Buy for $119!

Re: [Elecraft] KAT500 Remote software

2018-01-11 Thread ab2tc
Hi Jack and Don,

As Ron says, VFWD and VRFL are related to forward and reflected power.
Actually, they are roughly proportional to forward and reflected *voltage*.
I say roughly because there is some nonlinearity from the rectifier diodes,
especially at low power. The constant of proportionality is somewhat
dependent on frequency, power level *and * has some unit to unit
variability. That's the stated reason why Elecraft chose not to make any
estimation of actual power levels. But SWR is easily calculated b y the
formula:

VSWR = (VFWD+VRFL) / (VFWD-VRFL)

This formula factors out all the variability mentioned above except the
diode nonlinearity.

In your case this works out as (225+3) / (225-3) = 1.03

Since SWR is all that is required to be known in an autotuner, that's all
the KAT500 is calculating. Actually the calculated SWR doesn't even have to
be very accurate as long is it a monotonic function (no dips or peaks) of
the actual SWR.

To be fair, the KAT500 does need an estimate of forward power since that is
being used to fault if it is too high, but it doesn't have to very accurate.
The forward power is proportional to VFWD squared.

Re: [Elecraft] Hexkey correction and abject apology

2018-01-11 Thread Fred Jensen
Sorry, a technical difficulty in my mind.  I take a photo of my station 
periodically, usually when I change something.  I found the paddle in 
question, it was somewhat old when it was given to me.  It is *not* a 
hexkey, it has a trapazoidal base, narrower in back.  It does have the 
"yoke" arrangement of the BY-1 but it is more square-ish.  From the 
photo angle, I can't see if it had the spring looped around the post.


I also have a photo of my HexKey from Elecraft and it is *definitely 
not* a BY-1 mechanism.  I would still have it, and the $400+ wife spent 
on the ZN-SL single-lever for my birthday, were it not for my decreasing 
ability to manipulate the dual paddle with either hand.  It, and the two 
BY-1's I still have, were/are touchy to adjust.  I never became 
iambicized so I lost nothing going to the SL and regained the ability to 
send over 25 WPM.


I apologize for the mixup

Hello Fred!

I have a BY-1 as well as an Elecraft-branded Hex key.

The mechanisms on the two paddles I own are completely different.

The BY-1 uses a spring looped around a post for return force.

The Hex Key uses magnets for return force adjustments.  Unlike the 
BY-1, both paddle arms on the Hex key are independently adjustable for 
travel as well as force.


I agree with you that they botched it a bit by using coarse instead of 
fine threaded screws for adjustment, and on mine at least the magnets 
are not well-centered on the screws which makes the force adjustment 
even more difficult to fine-tune.

Re: [Elecraft] Elecraft Hex Key worth?

2018-01-11 Thread Petr, OK1RP/M0SIS
Yes, of course as Gus said the Bencher BY-1 is far different - single pivot,
spring tensioning, no adjustment. (Set spring tensioning, no adjustments to
make other than desired contact spacing)
It is completely different system compare to Hex key. It is not possible to
mix up them...

Re: [Elecraft] Long wire antennas

Plus the fact, the longer the wire, the more the radiation pattern 
approaches the wire axis.  Thus one will gain some along the axis 
direction and loose in other directions.  There is no free lunch.


"long" here means >a few wavelengths.

Re: [Elecraft] KAT500 Remote software

2018-01-11 Thread Don Wilhelm

Jack,

For any wattmeter (the one in the KAT500 included), the VFWD and VRFL 
values are related to forward power and reflected power.  Those are raw 
numbers and some math is required to calculate the actual power and SWR.


VRFL subtracted from VFWD can be used to computer the power into the 
load (in this case the input to the KAT500), but you need to know the 
scaling factor that may be unique to the wattmeter.


Similarly, if you divide VRFL by VFWD, you will obtain a result that is 
related to the SWR.


See the formulas associated with SWR in most any book dealing with 
antennas and transmission lines.
