Re: [Elecraft] Inverted L for 160 meters

[Edward R Cole]

Kevinr,

I have an inverted-L on 630m (that is 475 KHz) and is simply a 
vertical section with one horizontal section.  A quarter wave 
vertical for 1.8 MHz would be 137-foot high so 80 foot is going to be 
short.  The horizontal wires add capacitance to the top end of the 
vertical effectively shortening the length needed for resonance.


My inv-L is only 43-foot high (1/4WL= 524-feet) so its not very 
efficient and requires a big loading coil in series to resonate.  If 
you have four top-hat wires that may work better to shorten the 
needed vertical.  But probably still need a loading coil.  Use EZNEC 
to model it and it will provide a close est of the antenna Z.  I 
modified my MFJ-269B to operate 400-800   KHz and directly measured 
mine; adjusted coil to reach resonance.


Also do not forget it also needs ground radials (more the 
merrier)!  I only had a 100-foot square patch of ground for my inv-L 
so radials are very short as well.  But my signal has been heard 
4,000 miles away with 4w EIRP (100w output from amp).  Antenna is 
currently down.

Re: [Elecraft] Inverted L for 160 meters

[WA8JXM - Ken]

FWIW, I use WSPR to compare antennas.  That usually gives me a 
comparison list of more than a dozen receive stations.  I do multiple 
transmissions and then compare the differences.   There may be 
propagation changes during the different transmission periods but a 
couple of repeats seems to average that out.   It not only provides data 
in different directions but also different distances.


To get a same time comparison, I have used dual transmitters on slightly 
different frequencies but that gets complicated.

it flaws also, what's the pattern.

Re: [Elecraft] Inverted L for 160 meters

If you are going to go with buried radials, I don't think 4 or 5 of them 
is going to do a very good job for you.


Like N7WS recommended, look up N6LF's work and read it carefully. Seriously.

Re: [Elecraft] Inverted L for 160 meters

[Ted Edwards W3TB]

So Michael — what do you use for a baking between the open wire feeder and
the coaxial outputs of the KPA500?

Go go with noises of a vertical antenna, a separate quiet receiving antenna
like a K9AY is helpful.

Important is to have fun.

Re: [Elecraft] Inverted L for 160 meters

[john]

KD5ODS is not over thinking anything.  He is on the right track, an inverted
L is a much better top band antenna than a low all band horizontal wire.
Kevin just needs to model his inverted L, he might be a little surprised to
see which way the pattern skews.

Good gracious.  Why does everyone overthink 160m?  OK, maybe just because

But as to operation, I have one (1) antenna, and it is a 360 foot EDZ

Re: [Elecraft] Inverted L for 160 meters

[Jim Bruce]

For mine I have 1/4 wave wire for 160, goes up 35-40 ft and over to pole 
in corner of the yard with the remainder of the wire. I use mostly 
random length ground radials on top of the ground, some 1/4 wave, some 
sorter, some longer, mostly shorter,(someway shorter thanks to the lawn 
mower height), 12 so far and I add more when I get extra wire. 100 watts 
I work from here in Maryland to US west coast, Caribbean and into Europe 
and north Africa. I am happy for now but want to get more vertical 
height some day. Radials are sections of free 2 each 1000 foot rolls of 
4 pair cat 5 cable.

Re: [Elecraft] Inverted L for 160 meters

[Barry LaZar]

Kevin,

    Your instincts are right on. But, to answer your question the  
radials do not need to be 130' long, but it is better than a shorter 
set. The inverted L represents a 1/4 wave over ground and needs the 
other half, the radials. But, here is where it gets a little tricky. 5 
radials are not enough if they are on the ground, but elevate them and 5 
starts to represent a better counterpoise. I have a 132 feet of wire for 
an inverted L but, I only go vertical for ~61'. I, too, have only 5 
radials and they vary in length to fit my backyard; the horizontal 
section of my antenna goes over the house. The antenna does work well on 
160-40 meters, and 1/2 the time I use it on 30 and 1/2 the time  I use a 
20 meter vertical dipole on 30; it's a pattern thing.  And, I have only 
these two antennas.


    I do have a suggestion. That is feed your inverted L with a remote 
antenna tuner. This will allow your antenna to be used on other bands 
and keep loses low on the transmission line when high SWRs are present, 
and they will be. How much loss? that will depend on the feed line you use.

Two reasons why I want to use an inverted L.  One) it fits my property

I currently have an extra long doublet.  I can't remember the exact 
length but seem to remember over 120 feet for each leg.  The tuner on 
my K3 just won't match it below 2:1.0 so I don't want to transmit on 
it.  It hears well enough but just won't match.


Reason number two pushes me onward :)

Re: [Elecraft] Inverted L for 160 meters

[kevinr]

I have to be very careful of raised wires on my property.  If they are 
not above the height of an elk's antlers I am in trouble.  I plan to 
bury them.  This is something I've never done before which has its own 
merit.  I have plenty of wire scrap from broken antennas so the 
non-resonant, buried radials work better for my circumstances.  I need 
to calculate the feed point impedance to see if I need to design a balun 
for the system to work.  Once my main project is done I'll have more 
time for modeling each method.


   Thanks for all the ideas guys,

should be made to get all of the currents the same.  The last thing 
you want is a fifty ohm feedpoint impedance with a shortened vertical 
(which is what an L is).  There is evidence that elevated radials are 
an improvement over on-the-ground or buried radials.  Mine are on the 
ground, mainly because 1) I didn't want to give up radiator height to 
raise the radials, 2) all of the big guns bury theirs and I don't have 
room for full length radials anyway in my cactus patch.  See my QRZ 
page for evidence.


My modeling shows a little bit of directivity away from the horizontal 
wire, but it's negligible.

Re: [Elecraft] Inverted L for 160 meters

[kevinr]

I am hearing quite a difference between my inverted V and my 1/4 wave 
over a ground plane.  For the last few weeks I've been hearing less 
noise on the vertical.  Enough less to pull more ops out of the noise.  
When I try the inverted L I expect there to be a little more noise than 
the vertical, but less than the doublet. Now to test that hypothesis.

Re: [Elecraft] Inverted L for 160 meters

Interesting, I have a doublet 125 feet per leg and fed with 600 ohm true open 
ladder line (not window line) and the K-3 and KAT-500 both tune it to 1:1 160-6.

Feed point 40 feet up with ends at about 10 feet each. So inverted Vee.

Re: [Elecraft] Inverted L for 160 meters

[David Gilbert]

Why not model it?  It would be very easy to do using the free version of 
EZNEC that comes with the ARRL Antenna Book, and you'd be able to try 
various combinations (like the fact that you could probably get away 
with just one counterpoise wire like I do) to see the effects.

**Radial elements on the ground can be of any length, longer [up to a 
point] is better.  Their purpose is to provide a lower loss path than 
the earth for the return circuit. Elevated radials should be tuned, 
usually 1/4 wave, to be effective.  You can think of them as the "other 
half" of the vertical radiator, and if you had room and could fold them 
down, you'd have a center-fed half wave antenna fed at 180 deg.
  The feedpoint should somewhere above 50 ohms impedance.  As I add 
more radials that number will reach 50 ohms asymptotically.
**Radiation resistance will be somewhere in the 50 ohm ballpark.  
Generally, the radiators are not resonant due to physical constraints 
and there will be some reactance in the feedpoint impedance.  That is 
generally cancelled with a series capacitor [center conductor to 
radiator] or base inductive loading.


I can get the vertical part up to 70 or 80 feet above ground with the 
rest of it horizontal.  Most of the radiation should take place from 
the vertical part since it is closer to the feed point. 
**True.  For the most part, the horizontal part acts as a capacity hat.  
Shipboard antennas for 600 m were often one or more horizontal wires 
between two masts with a downlead to the transmitter.  Most [nearly all] 
of the radiation came from the downlead.
But there should be some effect from the direction of the horizontal 
portion.  How strongly does the direction of the horizontal portion 
effect the radiation pattern of the antenna system?
**It will have a small effect.  So will the arrangement of the radials 
if they are asymmetric in spacing around the radiator or in length.  In 
every case I've seen, the "Fly Poop Axiom"++ applies: Unless you're a 
broadcast station seeking to maximize field strength at the limits of 
your effective coverage, the effect is way below the other vagaries of 
Top Band.
My property allows me to point it from 300 degrees around to 200

feet above ground.  Spar poles and cranes clear out any dead limbs 
across the road.
The effect of having one of them take down your antenna will be far, far 
greater than that produced by precisely aiming the horizontal wire over 
their territory.  Keep it away from the loggers ... with today's 
equipment, they rarely look up anyway.  It's the Fly Poop Axiom vs the 
Elephant Poop Axiom. [:-)

Re: [Elecraft] Inverted L for 160 meters

[Rick Robinson]

I use a L for all HF band . One wire going up about 60 feet then goes
horizontal about 85 feet or so. I use a somewhat equal length elevated
radial about 10-12 feet off the ground. I use a couple of auto couplers,
depending on the radio . A Icom AH-4 for my Icom radios and an SGC 230 for
anything else. I don’t run an amp on HF so these work great. I also have a
ICE discharge unit to bleed off static to the tuners. This cuts off at 30
MHZ, which is ok as I have separate 6 meter antennas. There are many
references to match the antenna and many around here in hilly WV use
elevated radials, usually only one to facilitate proper matching.

Re: [Elecraft] Inverted L for 160 meters

[kevinr]

Two reasons why I want to use an inverted L.  One) it fits my property 
well.  Two) I have never tried one before.


I currently have an extra long doublet.  I can't remember the exact 
length but seem to remember over 120 feet for each leg.  The tuner on my 
K3 just won't match it below 2:1.0 so I don't want to transmit on it.  
It hears well enough but just won't match.


Reason number two pushes me onward :)

Re: [Elecraft] Question on KPA-1500 Operation

[Dick Dievendorff]

I’ll check when I get back home. We shouldn’t be clipping anything related to 
ATU if the ATU is bypassed, or if the ATU settings required are already set. We 
have to interrupt to change ATU relays if the ATU is not bypassed and different 
ATU setting is needed.

Re: [Elecraft] K3 on 2 meters

[Charlie T]

I never bought any extra stuff for my internal 2M transverter and I've used it 
on quite a few VHF contests etc.
So, as far as I'm concerned, the REFLOCK option is definitely NOT required for 
normal 2M CW/SSB contacts.
The regular calibration routine gets me close enough for anything I'd be doing.

Ronnie, it's a REFLOCK board that is installed INSIDE the 2M module It is 
"highly recommended" (was), so that IMPLIES that the 2M module can be used 
without it, but at some sort of reduced accuracy in frequency I would guess.

My 2M module install turned into the need to ship it in and fix several issues,

Works now...  I'd ask Elecraft

[Elecraft] Question on KPA-1500 Operation

[N2TK via Elecraft]

Can someone answer this question?

Thanks,

N2TK, Tony

 

 

Here's a question for you:

 

Scenario:  KPA-1500 **NOT** interfaced to a radio.

 

Set Up:  KPA-1500 ATU in bypass.  Mode is Operate.

 

Test:

 

1.  Put amp on 14 MHz band by pushing the button.

2.  Monitoring on another radio connected to no antenna.

3.  Put transmitter on 14025 kHz and send a C on the paddle or via memory keyer.

 

Question:

 

On the separate RX, was the first dash in the C clipped?

 

4.  Move the transmitter and separate RX to 14050 kHz.

5.  Send another C on the paddle or memory keyer.

 

Question:

 

Was the first dash in the C clipped?

 

My reason for asking:  Doing this test with the SPE 2K-FA results in first dash 
of the C being clipped.

Why is this important:  In SO2V when CQing on VFO-A, and S on VFO-B, the 
2K-FA's firmware

sees the 14025 RF and adjusts the internal ATU for that frequency EVEN IF THE 
ATU IS BYPASSED.

When a spot in VFO-B is called, if VFO-B is in another ATU segment, EVEN IF THE 
ATU IS BYPASSED,

the amp goes into bypass, realigns the ATU for the new segment, and then goes 
back into operate,

the result being that the first character of the transmission of VFO-B is 
clipped.  Many times when I

dump my call in on VFO-B to answer a CQ on that frequency, the guy comes back 
"?" since my N is

clipped into something unrecognizable.

Re: [Elecraft] APF Primer?

[huntinhmb]

Here's my take on the APF.  I use it a lot during QRP Fox Hunts and I just used 
it to pull G3SED out of the weeds on 20. 
 
Best conditions are when only random band noise is in the passband for my 
technique although it can be used in conjunction with the NB (the IF blanker, 
not the DSP option). The passband should be QRM free.
 
I set the DSP passband to about 700 Hz and turn on NR set to NRm5-3 or so.  
This is fairly light noise reduction with a level of unprocessed noise+signal 
mixed in.  Since there is only random noise in the passband that level of NR 
works well.  I use this to tune around looking for the Fox. 
 
When I find a signal of interest, I turn on the APF and peak the signal in the 
very narrow passband using FINE tuning.  I also frequently use an audio 
spectrum display on the PC to center the signal on the marker which is set to 
the CW pitch frequency.  Although the APF is very narrow:  ~30 Hz at -3 dB, the 
sharp peak is more like 5 Hz wide so FINE tuning is needed and the marker helps 
because my ears aren't that good at matching pitch.  You can set the DSP filter 
narrower than 700 Hz to eliminate some QRM but that seems to be the sweet spot 
for the NR to work well.
 
To your other questions ... 
Make sure the noise level is not activating the AGC or it will be working 
against you.
Really no band preference but it's better not to have big static crashes to 
deal with.  Set AGC to fast if there are.
 
It took me a while to figure this out.  Have fun!

medium QSB against medium to high noise levels?  Is it better on 80, 40,

Re: [Elecraft] APF Primer?

[Fred Jensen]

Kevin:

1)  For a K3, APF seems to be very dependent on current AGC action. If 
there are very strong signals close in and the AGC is doing its thing, 
APF doesn't seem to work.  You can adjust the AGC parameters, however my 
experience is that I use APF infrequently enough that it's better to 
adjust the AGC to non-APF situations.


2)  The APF will ring, it is very narrow.  With APF on, using a wider 
DSP BW [400 or 500 Hz] will help some.  Tuning just off the peak, if 
possible, can also help although even at 1 Hz tuning, sometimes that's hard.

As I mentioned, I have gotten it to work well a few times, but usually 
the signal sounds buried in a hard walled well.  Then I get emails

Re: [Elecraft] Fwd: no8v: APF Primer? - 2020-08-25

[Bill Frantz]

APF is not a cure all. It is an alternative to narrowing the 
bandwidth to the minimum to try to improve the signal to noise 
ratio. If there are strong signals near the one you are trying 
to receive, from a crowded band or DQRM, then it isn't going to 
help. If the band is reasonably quiet around the signal, it can 
make reception possible.

Re: [Elecraft] K3 going expeditionary

[K8TE]

As is often the case, connecting directly to the battery for the negative
lead is misunderstood.  In today's world, it depends.  The Battery
Monitoring System (BMS) is a big deal in most of today's vehicles.  To
function properly, we should NOT CONNECT to the battery's negative terminal. 
That used to be good advice and may be bad today.  See:  
http://www.k0bg.com/wiring.html.

As Alan, K0BG, states, "It WORKs." often means "WithOut Real Knowledge.  Not
all advice on this reflector is current or correct.  Caveat emptor.

BTW, using vehicle wiring for a 100 Watt radio can lead to losing the
vehicle due to fire!  I have seen the pictures.

I worked in the Gulf of Mexico oil fields.  I swatted down with gusto the
idea of "It's only temporary." and "I can do it quickly."  Do it right, even
if it's for an hour or a weekend.

The   K144RFLK  is showing as available on this page.  However, clicking the 
item takes you to a page suggesting to “signup” on an interest list. 

https://elecraft.com/pages/k-line-transceiver-k3-k3s

Also, to use an external 10MHz reference,  K3EXREF is required.

My K3S is currently in Watsonville for “final upgrading”, and two items to be 
installed are the K144XV and K144RFLK.

If your K3 has been upgraded to KSYN3A, there is an additional mod that the 
KREF3 Reference Oscillator should undergo.

[Elecraft] Fwd: no8v: APF Primer? - 2020-08-25

Hi Kevin,

I have used APF to find you on ECN/20. When QRN/QRM was high and signals 
were weak, APF sometimes enabled me to hear and recognize you by the 
rhythm of your sending. Without APF, I could not hear you at all.


Normally I tune for you with a WIDTH of about 25 Hz, but when I switch 
to APF, I also broaden WIDTH to its default CW value of 400 Hz to help 
minimize ringing. I also change the tuning rate to FINE to avoid missing 
the APF peak. It should be possible to automate both of those changes on 
the K3, although I have not yet done so.


APF is no panacea. It does ring, which makes copy difficult. But 
sometimes it saves the day.


73,

John, no8v

Re: [Elecraft] K3 on 2 meters

[Phil Hystad via Elecraft]

OK, I am curious…

Why was not this reference clock board not built into the 2-m option board in 
the first place.  Overall I can’t imagine that the net cost would be as much as 
designing and separating out an optional PCB and all that goes along with that 
as the combined cost of the 2-m option and reference clock now.

After all, it was recommended for SSB and CW use.  Now, I suppose that there 
are possibly people in this world that would buy the 2-m option only for FM 
comms but given that a nice separate 2-m FM rig would be cheaper it doesn’t 
make sense to me to add something like that to the K3/K3S.

[Elecraft] Elecraft SSB Net from Sunday 8-23-2020

[Eric Lanzl]

Here are the SSB Nets that take place on Sundays. You do not have to have an 
Elecraft Radio to check in to the net. We ask for the call sign, name, state, 
type of radio. If it is an Elecraft radio the model and serial number.

20 m. 1800Z   14.303.5 Net Control Eric WB9JNZ    IL

40 m. 1900Z   7280    Net Control Steve WM6P   GA

80 m.  0100Z  3942    Net Control Paul    KB9AVO    IN

Once again thank you to all the relay stations for their help hearing the 
stations that net control does not hear in an attempt to get everyone who wants 
to check in a chance to participate in the net. I hope to hear you on one or 
more of the nets this coming Sunday. Eric WB9JNZ

[Elecraft] K3 on 2 meters

[Ronnie Hull]

I recently purchased a complete KV144 kit to install in my K3. I’m told that if 
I want to use it on 2M SSB OR CW that I need another board. A ref lock or some 
such that is, of course ( my bad luck as usual) no longer available from 
Elecraft. What exactly is the Board I need?

Does anyone have one they are willing to sell?

Thanks in advance

Hi Eric;
Make sure it is in plain-text.
Make sure you don't have a "signature".
I will look more closely at the reject message I get next time.

Re: [Elecraft] help net information submission

[Nr4c]

Are you creating txt or HTML + txt?

Are you doing pdf files?

Try submitting a very small file, maybe two lines of log. See if it’s the 
submittal process or the file itself.

[Elecraft] help net information submission

[Eric Lanzl]

For the last several weeks my submission of the SSB net logs keep being 
rejected by the forum as being too large. I have submitted them the same way as 
I have before. Can anyone help me understand why I can no longer submit the 
logs? Any ideas?
