Re: [Elecraft] K3/K3s Ethernet Interface

2015-07-19 Thread Paul Christensen
Jack,

All valid points but take note of K9HZ's work as a start.  Nevertheless, let's 
say native Ethernet control isn't worth the engineering effort.  That should 
not preclude the integration of RemoteRig as an option into a K3/K3s.  

If I didn't care about the resale value of my K3 or RemoteRig, I could easily 
turn this into a weekend construction project and be up and running on Monday 
morning with an Ethernet cable hanging from the back of the K3.  

The RemoteRig board would come out of its enclosure then mount in the K3.  It's 
just a matter of adding an RJ45 port, tapping +12V, internal audio, RS-232, 
PTT, key line, and ACC.  The tapping of RS232 and audio is not trivial but it 
is completely manageable. 

While this adds little additional operational utility than it does now, it 
significantly cleans up K3 cabling with RemoteRig.  No change is needed at the 
client end for use with the K3 mini.  For K3 clients, a similar integration 
could accomplished or kept as it is now with external cabling.  

Of course, there must be enough demand from remote users to make it worthwhile 
as well as cooperation from Microbit.

 The Holy Grail is an Ethernet interface that includes (optional) integrated

 that manages K3 Ethernet connectivity with or without RemoteRig attributes.
 Don't need Ethernet? Then don't get the board.  Since the RemoteRig hardware
 is mature and consumes little circuit board space and DC current, perhaps it
 would be worth opening up a discussion with RemoteRig's designer since
 Elecraft already has a close relationship with Microbit.I know rear

I use two different portable antennas, One is the super antennas yp3 3 element 
antenna and the other is the TW 2010 antenna. If i'm going to be portable for a 
while Ill put the 3 element antenna up. Its pretty fiddly and changing bands is 
a pain. Its one band at a time. The performance is very good and it really 
lightweight and small to pack.The TW antenna works great and takes 5 minutes to 
set up. In a nutshell it's a DX antenna. Distant stations are worked with 
amazing frequency for such a small antenna. Its my favorite portable. Its 
actually larger to pack than the 3 element without the mast. However, that 
fades when its quickly set up and working. Like any antenna, keep them away 
from noise sources and in the clear and the results will be good.

It's pricey, but you can make one yourself for about 1/10th the cost. 
Just remember, these guys are resonant transformers and MUST be at 
resonance so bypass the ATU.

The EFHW is very popular with the SOTA crowd, extremely light, only 
needs one support.  Mine works best with a 6 pigtail hanging off the 
shield of the BNC connector.  They too seem to be fairly immune to 
ground, low current down where you are.

My meager experience is that any antenna you can make resonant will 
probably perform a little better than a random wire, but I've made a lot 
of KX1 Q's with a 26 ft wire and counterpoise made from a piece of RG-58.

KT5X believes [and I don't disagree] that vertical ground planes on 
mountain tops tend to radiate downhill which isn't real useful.  If 
you're above the timberline, you're probably on a mountain.

 Hi all,

 Have you found the perfect above-the-treeline backpacking antenna
 for use with your KX3 or other small rig? I've used everything from a
 10-meter coat hanger whip, to a yagi that breaks down into two dozen
 pieces, to a dipole held up at the center by a willing (and tall)
 campmate. The variety (and price range) of such antennas is
 staggering.

 I've had pretty amazing results using short, base-loaded antennas on
 the higher bands--especially when conditions were good. My personal
 best is JA from W6 on 15-meter SSB, running 3 watts to a Maldol 48
 whip. These antennas collapse and break down into just two pieces,
 taking very little space in my lightweight go-bag. This leaves room
 for a couple of 25' wires, adapters, and weights for times when there
 are trees available.

 But the search for the ideal miniature HF antenna continues:
 something both very compact *and* highly efficient. Ideally it would
 break down to a length of 8 or less, do an excellent job on 20
 meters and up, and earn a passing grade on 30 and/or 40 meters.

 One other key factor, at least with the KX3/KX1/K1 genre, is to take
 maximal advantage of the rig's internal ATU. A wide-range ATU (such
 as the KXAT3) can turn a narrow-banded antenna into one that covers a
 full band or even multiple bands, within limits. One general approach
 is to coarse-tune the antenna's own inductance, then let the ATU do
 cleanup.

 Is the best antenna for backpacking a very small magnetic loop? A
 cleverly designed, center-loaded telescoping whip? A length of #30
 wire lofted by a small helium balloon? (Or, more intriguingly, some
 combination of these?)

 I'd be interested in hearing about your antenna theories and field
 experiences, backed up by entertaining fish stories, if they aren't
 embellished to an embarrassing degree. If your supporting
 documentation is too voluminous for the forum (attached photos,
 etc.), feel free to email me directly.

 If anything substantive or surprising emerges, I'll do a followup
 posting.

Correct.  JT-65 has common frequencies on each band.  Then JT-9 is about 
2 kHz higher from JT-65, thus the move in frequency.  There is a box to 
be checked on the application when changing from JT-65 to JT-9.  It is 
best if the radio is under CAT control. Most issues in this regard are 
resolved by the software.

Re: [Elecraft] K3/K3s Ethernet Interface

2015-07-19 Thread Jack Brindle
Cool! Please publish the specs. How secure it it? SSL? TLS 1.2 (or better)? 
Will there be accommodations for upgrades as security problems are found?
Does it do ipv6 (which is rapidly becoming a requirement)?

My concern is this - we are putting a rather powerful transceiver on the 
internet. With Telnet or any other non-secure format/protocol there is a lot of 
potential
for someone to take over the data stream and use the transceiver for their use. 
Even with secure protocols there has been a very poor record of vulnerabilities
and other problems taking over computers, breaking in for information or other 
problems. Exposing a ham transceiver to this endangers your license and
our spectrum. Anything that is not secure should not come close to a radio. 
Today that means TLS 1.2 and full security. And updates to fix bugs as they are
exposed.

We are at the beginning of the age of IOT, the Internet Of Things. There are 
many very good manufacturers working on chips and interfaces
for embedded devices - refrigerators, lights, cars, and even ham transceivers. 
These will be secure and will accommodate the requirements
I describe above and many more in a way that allows us to simply expand the 
radios we have now with new cards. This stuff is starting to
come to market now - I would suggest we are a year to two off from adding them 
to our devices.

Then we need to convince the ham software developers to start adding support 
for them in all the flavors that already exist. I suspect that won’t
be very difficult when they find a willing market.

Good luck with your venture. I’d love to see it when it becomes available. We 
need to see things like this to interest hams, show them (and us)
what is possible, advance the state of the art and even to expose 
vulnerabilities with current schemes so we can all do (and demand) better.

p.s. Yeah, security is THAT important.

Re: [Elecraft] Miniature self-supporting HF antennas

2015-07-19 Thread Fred Jensen

Usefulness of any 10 meter antenna is declining. :-)

FWIW:
My Buddipole weighed 17 lbs, and I sold it and used the proceeds to get 
an AlexLoop.  It weighs about 1.6 lbs, less if I take it out of the neat 
canvas case, 2 lbs with the lightweight tripod.  I like it a lot.  I can 
set it up in less than 5 min, it is pretty much immune to anyone's 
definition of ground, and it works very well.  Touchy to tune on 40, 
not so bad on 30 and easy on 20 and the rest.  Very narrow BW, I sit 
under it so I can reach up and tune it using the K2 SWR indication. 
It's pricey, but you can make one yourself for about 1/10th the cost. 
Just remember, these guys are resonant transformers and MUST be at 
resonance so bypass the ATU.


The EFHW is very popular with the SOTA crowd, extremely light, only 
needs one support.  Mine works best with a 6 pigtail hanging off the 
shield of the BNC connector.  They too seem to be fairly immune to 
ground, low current down where you are.


My meager experience is that any antenna you can make resonant will 
probably perform a little better than a random wire, but I've made a lot 
of KX1 Q's with a 26 ft wire and counterpoise made from a piece of RG-58.


KT5X believes [and I don't disagree] that vertical ground planes on 
mountain tops tend to radiate downhill which isn't real useful.  If 
you're above the timberline, you're probably on a mountain.

Hi all,

Have you found the perfect above-the-treeline backpacking antenna
for use with your KX3 or other small rig? I've used everything from a
10-meter coat hanger whip, to a yagi that breaks down into two dozen
pieces, to a dipole held up at the center by a willing (and tall)
campmate. The variety (and price range) of such antennas is
staggering.

I've had pretty amazing results using short, base-loaded antennas on
the higher bands--especially when conditions were good. My personal
best is JA from W6 on 15-meter SSB, running 3 watts to a Maldol 48
whip. These antennas collapse and break down into just two pieces,
taking very little space in my lightweight go-bag. This leaves room
for a couple of 25' wires, adapters, and weights for times when there
are trees available.

But the search for the ideal miniature HF antenna continues:
something both very compact *and* highly efficient. Ideally it would
break down to a length of 8 or less, do an excellent job on 20
meters and up, and earn a passing grade on 30 and/or 40 meters.

One other key factor, at least with the KX3/KX1/K1 genre, is to take
maximal advantage of the rig's internal ATU. A wide-range ATU (such
as the KXAT3) can turn a narrow-banded antenna into one that covers a
full band or even multiple bands, within limits. One general approach
is to coarse-tune the antenna's own inductance, then let the ATU do
cleanup.

Is the best antenna for backpacking a very small magnetic loop? A
cleverly designed, center-loaded telescoping whip? A length of #30
wire lofted by a small helium balloon? (Or, more intriguingly, some
combination of these?)

I'd be interested in hearing about your antenna theories and field
experiences, backed up by entertaining fish stories, if they aren't
embellished to an embarrassing degree. If your supporting
documentation is too voluminous for the forum (attached photos,
etc.), feel free to email me directly.

If anything substantive or surprising emerges, I'll do a followup
posting.

Richard,

Two properly spaced and phased radiators are all that is necessary for a 
2 element beam - two Alexloops, 2 verticals, two dipoles, etc.
While setup in 2 minutes may not be practical at 20 meters, it is 
practical at 2 meters, and you may even devise something that looks like 
an umbrella.  Think of the Hex Beam - 2 elements that sort of look like 
an inverted umbrella.

I recently used a 20m EFHW to operate from 12,300' Trail Ridge (SOTA
W0C/FR-123) on June 28.  I wanted a very quick activation due to
thunderstorm concerns so I took a 15' mast (collapsible to ~18 inches),
mounted it to a cairn of stones with a bungee and attached the far end to a
stone.  I made 6 contacts in 6 minutes and then beat a hasty retreat down
the summit.  About an hour earlier and 60 miles south of me several hikers
were struck by lightning as they descended Mt. Bierstadt (see below).

Yes.  The P3 will tune up to about 22 MHz (and above that with reduced 
sensitivity).  If you go into the Xcvr Sel menu item and select the 
last item in the list, called 0 Hz. the P3 is tuned directly to the 
frequency on the screen.


Tune using the CENTER control.  (Center En has to be enabled in the 
menu.)  The tuning rate is proportional to span, so select wide span for 
coarse tuning and then narrow span to dial in to the exact desired 
center frequency.


One warning:  The P3 IF input is unprotected so it is easily damaged by 
static discharge or high power.  I recommend adding a pair of 
back-to-back switching diodes in parallel across the IF input.  I did 
that using a BNC T connector and BNC plug so I wouldn't have to modify 
the P3.

Jack,

All valid points but take note of K9HZ's work as a start.  Nevertheless, let's 
say native Ethernet control isn't worth the engineering effort.  That should 
not preclude the integration of RemoteRig as an option into a K3/K3s.

If I didn't care about the resale value of my K3 or RemoteRig, I could easily 
turn this into a weekend construction project and be up and running on Monday 
morning with an Ethernet cable hanging from the back of the K3.

The RemoteRig board would come out of its enclosure then mount in the K3.  It's 
just a matter of adding an RJ45 port, tapping +12V, internal audio, RS-232, 
PTT, key line, and ACC.  The tapping of RS232 and audio is not trivial but it 
is completely manageable.

While this adds little additional operational utility than it does now, it 
significantly cleans up K3 cabling with RemoteRig.  No change is needed at the 
client end for use with the K3 mini.  For K3 clients, a similar integration 
could accomplished or kept as it is now with external cabling.

Of course, there must be enough demand from remote users to make it worthwhile 
as well as cooperation from Microbit.

In the NAQP RTTY, I observed a station on the other side of the 
continent with a 20-25 KHz noise bump above [but not below] his 
signal.  It was 8-10 dB above the ambient noise baseline.  I watched it 
for quite awhile and every time he transmitted, it appeared, and when he 
finished it disappeared.  No other station, even very strong ones, 
exhibited this effect.


It's hard to conjure up how any form of phase noise would be asymmetric 
like this.  It could be some form if IMD in his TX RF chain, I guess. 
Another possibility is he was running AFSK USB and the noise was being 
generated in the sound card.  This could easily be me as well and I'd 
like to check.

Re: [Elecraft] KX3 FD Operations?

2015-07-19 Thread Kenneth Christiansen
Hi to the group

I know this is long so if you are not interested in Solar Field Days please hit 
delete.

I am late telling about my experience with Field Day but I had so much research 
going that I wanted to wait until after my two week vacation to tell you all 
about it.

I have been using class 1B ND battery all but one of the last 15 years. I 
started with my K2 built in 2000 along with a Radio Shack Tandy 1100FD laptop 
all running on an old group 27 battery. The year the battery was 18 years old 
it failed about 6 hours before the end of field day and would not take a charge 
again. I bought another group 27 battery and used my K3 and the 1100FD laptop 
the next year. The club talked me into running under my call the following year 
as a 100w 3A ND station using a Windows XP laptop and N3FJP software. The next 
year I had my new KX3 and went back to 1B ND battery. I used the I-PAD and 
Hamlog software but the I-PAD battery ran out of battery after just 7 hours of 
use. Last year I ran the KX3 and a Windows 8 laptop as 1B ND Battery but had to 
run the 40 watt laptop as the only load on my generator. I understand that 
meets the rules but I did not like it.

This year I replaced all the lights in my camper with LED bulbs and dropped the 
load from 1.5 amps per bulb to 0.2 amp per bulb. I found a Verizon 12 volt 
power supply that would run an I-PAD and Hotspot at the same time on a 
discharging 12 volt battery. The I-PAD used about .4 amp as long as I was 
careful to turn the I-PAD OFF instead of to STANDBY when I was not using it. 
The I-PAD looks OFF when in STANDBY but runs the battery down doing things in 
the background and charges the battery when it is turned back on which draws 
additional 12 volt from the battery. I programed the fast memories of the KX3 
for W0CZ, and 1B ND and used the built in paddles for anything else. You can 
see pictures of my camper and antenna on qrz.com. I also added a 33 ft MFJ 
fiber pole with a 29 ft vertical wire that loads on 40, 30, 20 and 15 meters 
using the KX3 built in tuner. A week before field day I was given ten five watt 
solar panels. Years ago I had built the KD5NDB solar regulator so I wir
 ed all 10 panels in parallel and the solar regulator to charge the battery. 

My results for field day were 132 cw five watt contacts with a claimed  QSO 
score of 1320 plus bonus points for 100% emergency power, Natural power QSOs 
completed and using the b4h.net applet. The solar charger had my batteries 
fully charged by the end of field day after operating all night.

Two days after field day we took off on a two week vacation to Northern 
Minnesota to camp grounds without electricity. I had the 8 year old group 27 
battery and a 4 year old group 24 battery as my only source of electricity. I 
also had the KX3, PX3 and KXPA100 along and used the station extensively. The 
solar charger was able to recharge both batteries every day the sun was out and 
help them on the other days so I never did use the small generator I brought 
along. In bright sunlight I was able to make several nice rag chew CW QSOs at 
100 watts. All my other contacts were at 50 watts night or day.

I made one more change to my solar project when I got home. It is a Home Depot 
Grape Solar GS-STAR-100W panel. I found when I was camping that it was a lot of 
work to move 10 panels so this way when the sun moves I can follow it by just 
picking up the one panel.

KD5NDB is a silent key and I do not know of anyone selling his kits but I did 
take pictures of his kit instructions and schematic drawing which I can E-Mail 
to anyone that wants to build this solar regulator. One advantage of his 
circuit is that it makes no RF noise. Many other SOLAR REGULATORS make serious 
RF noise.

73 and thanks for the band width

Re: [Elecraft] Miniature self-supporting HF antennas

2015-07-19 Thread Richard Donner
My two cents worth.  My favorite antenna  for SOTA
turns out to be the 20 meter Endfedz followed by the Alex Loop.
I have done a receive comparison between the Alex loop , Endfedz and a full
size 20 meter vertical with radials.   In this  sketchy little test the
Verical came out best followed very closely by the other two antennas.

It was amazing to see how well the 3 foot diameter loop performed.

I guess I would like a 20 meter 2 elment beam that sets up in 2 minutes and
weighs two pounds. If it could pop open and shut like an umbrella that
would work for me.   Any ideas.

Re: [Elecraft] Miniature self-supporting HF antennas

2015-07-19 Thread Matt Zilmer
My favorite is the bush sloper.  To launch it, I use an E-Z Hang
(slingshot / fishing reel).

The scrub on SoCal mountains is usable to support an end-fed wire,
facing downhill.  I recommend a counterpoise facing uphill.  The
end-fed can be 50 to 200 feet long (145 feet seems best all-around
match using the ATU).  I use a throway fishing weight to be the E-Z
Hang projectile, tugging the #24 wire along until it bashes into a
plant or the ground.  The weight is attached to the wire via a short
piece of thin monofilament, so it can break away without stretching
the wire.

I attach the radiator and counterpoise directly to the KX3 via a BNC -
Banana adapter.

When done, I just spool up the #24, usually losing the fishing weight
in the process.  If it's a multiple hilltop day, I have half a dozen
of these in my pack.

Being a sloper, it has some forward gain but a fairly high angle
because of proximity to the ground.  SoCal mountain ground is a
rather vague concept though and I've made a few dozen DX contacts
running 2-3W, CW.   I have WAS done this way, minus RI and VT.

I've had some luck using a tilt up telescoping aluminum 33 foot
vertical on 40 and 15m, but the dern thing is unwieldy and heavy to
pack around, and at 5.5 feet long (collapsed) only fits on my large
hunting pack.  I'd sure like to see a portable multi-band vertical
that's easier to lug around than this, maybe one that collapses to
less than four feet and weighs less than three pounds.  The 33 footer
weighs almost ten pounds  I've stopped punishing myself, and don't
use it much any more.

No fish stories today, sorry.

Hi all,

Have you found the perfect above-the-treeline backpacking antenna for use

held up at the center by a willing (and tall) campmate. The variety (and price 
range) of such antennas is staggering.

I've had pretty amazing results using short, base-loaded antennas on the 
higher bands--especially when conditions were good. My personal best is JA 
from W6 on 15-meter SSB, running 3 watts to a Maldol 48 whip. These antennas 
collapse and break down into just two pieces, taking very little space in my 
lightweight go-bag. This leaves room for a couple of 25' wires, adapters, and 
weights for times when there are trees available.

But the search for the ideal miniature HF antenna continues: something both 
very compact *and* highly efficient. Ideally it would break down to a length 
of 8 or less, do an excellent job on 20 meters and up, and earn a passing 
grade on 30 and/or 40 meters. 

One other key factor, at least with the KX3/KX1/K1 genre, is to take maximal 
advantage of the rig's internal ATU. A wide-range ATU (such as the KXAT3) can 
turn a narrow-banded antenna into one that covers a full band or even multiple 
bands, within limits. One general approach is to coarse-tune the antenna's own 
inductance, then let the ATU do cleanup. 

Is the best antenna for backpacking a very small magnetic loop? A cleverly 
designed, center-loaded telescoping whip? A length of #30 wire lofted by a 
small helium balloon? (Or, more intriguingly, some combination of these?)

I'd be interested in hearing about your antenna theories and field 
experiences, backed up by entertaining fish stories, if they aren't 
embellished to an embarrassing degree. If your supporting documentation is too 
voluminous for the forum (attached photos, etc.), feel free to email me

Re: [Elecraft] K3/K3s Ethernet Interface

2015-07-19 Thread Jack Brindle
Paul;

What is your proposal for the host-side interface? Pretty much all host 
programs these days use a serial interface. We usually use this through a 
USB-Serial adapter or through built-in serial ports, which are rapidly 
disappearing. To make this viable we would need drivers for all major platforms 
that implement a serial port  driver interface to ethernet. Or, the host 
programs will need to be modified. 

There is a lot of work needed to make this suggestion viable, both on the host 
and radio sides. This is the fact same reason we still use serial interfaces 
for our rigs instead of true USB interface.
Put forth a good proposal and let it be considered. Without that work (whoever 
does it), ethernet hardware isn’t very useful.

- Jack, W6FB

p.s., no, this isn’t a flame, but a challenge. Let’s get the whole thing 
viable, then we will take a good look at implementing it on all sides.

 This inquiry is directed to both the Elecraft leadership team as well as
 K3/K3s owners who may have an interest in native Ethernet connectivity.   In
 searching through the list archives, I noted that some K3 owners had
 previously expressed an interest in an Ethernet option - and some owners
 have been disappointed that the new K3s and KIO3B board does not include
 Ethernet connectivity.
 
 
 
 A bit of background: for the past few months, N4CC and I have been operating
 a remote Internet station that's located near the FL/GA state line.  Our
 setup includes a K3 and RemoteRig at the remote site and either a K3 or
 K3-mini at the control locations.  Since the installation, we've experienced
 almost no operating trouble and any issues that have developed are managed
 remotely though direct and back-door network access points. 
 
 
 
 Last week, I made some internal changes to the K3  and also added an
 external USB data interface device for RTTY.  What's apparent is that cable
 management is getting way out of control.  To gain inside access to the K3
 almost requires a meditation exercise before going in.  Consider that a PR6
 is mounted to the back of the K3.  The rear of the K3 is an absolute rat's
 nest of cabling.  With the RemoteRig and PR6, It was bad enough before the
 inclusion of the external USB sound car/interface, but now it's bordering on
 ridiculous.   Moreover, RemoteRig does not allow clean access to the K3's
 ACC DB-15 connector for other purposes such as FSK keying.  Sure, the
 connector can be opened to access pins, but it requires a wiring break-out,
 leading to yet a further rat's nest of cabling.
 
 
 
 To help deal with the cabling issues, I am replacing the external PR6 with
 the new KXVB3 board.  Next, a KIO3B board will be added when it's available
 to existing K3 owners.  That should eliminate the external sound card
 interface and clear up much of the cabling mess, but not all of it.  
 
 
 
 The Holy Grail is an Ethernet interface that includes (optional) integrated
 RemoteRig hardware - just one interface board [e.g., KIO3E(thernet) board]
 that manages K3 Ethernet connectivity with or without RemoteRig attributes.
 Don't need Ethernet? Then don't get the board.  Since the RemoteRig hardware
 is mature and consumes little circuit board space and DC current, perhaps it
 would be worth opening up a discussion with RemoteRig's designer since
 Elecraft already has a close relationship with Microbit.I know rear
 panel real estate is a concern, so it won't be easy to add yet another
 connector without adversely affecting other connectivity.  Thoughts?

Re: [Elecraft] Miniature self-supporting HF antennas

2015-07-19 Thread k3ndm
Wayne, 
From time to time, my radio club collars me to do a program at one of our 
meetings. I usually lecture on antennas targeting the new ham. There are two 
points I try to leave the crowd with: 

1. There is no such thing as the perfect antenna. Each is a compromise of some 
sort. 
2. No ham has too many antennas. 

Efficiency, size, effectiveness, cost, and bandwidth are all inter-connected. I 
wish you great success in your quest. I'll be watching as I too would like to 
discover the perfect antenna. Having said this, have you tried a vertical 
dipole fed with open wire or ladder line? You gain by having a low angle 
antenna with low transmission line loss, and it requires only one support.

Something like this was my 160M antenna in Chicago.



So if your wanting to just listen and get an idea of whats there,

Yes, except that if there's a choke at the feedpoint, you'll be using

Re: [Elecraft] Miniature self-supporting HF antennas

2015-07-19 Thread bill.va3ol
I am not an antenna purist and will use whatever is handy but my favourite
antenna (at the moment) are a 44 foot Center feed zepp with tv twinlead and
a 4:1 balun or if trees are not available I really like my semi homebrew
center loaded vertical using a 12 inch base rod, a Wolf River Silver Bullet
coil and a collapsible military whip for 80/40 or just a 36 inch whip for
20 - 10 if I want to be stealthy. I had a buddy stick but it is to finicky
to tune, whereas the Wolf river coil just slides down for maximum noise and
let the KX3/KXPA take the last bit of swr out. For radials you can't beat
the tape measure radials.

 Hi all,

 Have you found the perfect above-the-treeline backpacking antenna for
 use with your KX3 or other small rig? I've used everything from a 10-meter
 coat hanger whip, to a yagi that breaks down into two dozen pieces, to a
 dipole held up at the center by a willing (and tall) campmate. The variety
 (and price range) of such antennas is staggering.

 I've had pretty amazing results using short, base-loaded antennas on the
 higher bands--especially when conditions were good. My personal best is JA
 from W6 on 15-meter SSB, running 3 watts to a Maldol 48 whip. These
 antennas collapse and break down into just two pieces, taking very little
 space in my lightweight go-bag. This leaves room for a couple of 25' wires,
 adapters, and weights for times when there are trees available.

 But the search for the ideal miniature HF antenna continues: something
 both very compact *and* highly efficient. Ideally it would break down to a
 length of 8 or less, do an excellent job on 20 meters and up, and earn a
 passing grade on 30 and/or 40 meters.

 One other key factor, at least with the KX3/KX1/K1 genre, is to take
 maximal advantage of the rig's internal ATU. A wide-range ATU (such as the
 KXAT3) can turn a narrow-banded antenna into one that covers a full band or
 even multiple bands, within limits. One general approach is to coarse-tune
 the antenna's own inductance, then let the ATU do cleanup.

 Is the best antenna for backpacking a very small magnetic loop? A cleverly
 designed, center-loaded telescoping whip? A length of #30 wire lofted by a
 small helium balloon? (Or, more intriguingly, some combination of these?)

 I'd be interested in hearing about your antenna theories and field
 experiences, backed up by entertaining fish stories, if they aren't
 embellished to an embarrassing degree. If your supporting documentation is
 too voluminous for the forum (attached photos, etc.), feel free to email me
 directly.

 If anything substantive or surprising emerges, I'll do a followup posting.

[Elecraft] K3/K3s Ethernet Interface

2015-07-19 Thread Paul Christensen
This inquiry is directed to both the Elecraft leadership team as well as
K3/K3s owners who may have an interest in native Ethernet connectivity.   In
searching through the list archives, I noted that some K3 owners had
previously expressed an interest in an Ethernet option - and some owners
have been disappointed that the new K3s and KIO3B board does not include
Ethernet connectivity.

 

A bit of background: for the past few months, N4CC and I have been operating
a remote Internet station that's located near the FL/GA state line.  Our
setup includes a K3 and RemoteRig at the remote site and either a K3 or
K3-mini at the control locations.  Since the installation, we've experienced
almost no operating trouble and any issues that have developed are managed
remotely though direct and back-door network access points. 

 

Last week, I made some internal changes to the K3  and also added an
external USB data interface device for RTTY.  What's apparent is that cable
management is getting way out of control.  To gain inside access to the K3
almost requires a meditation exercise before going in.  Consider that a PR6
is mounted to the back of the K3.  The rear of the K3 is an absolute rat's
nest of cabling.  With the RemoteRig and PR6, It was bad enough before the
inclusion of the external USB sound car/interface, but now it's bordering on
ridiculous.   Moreover, RemoteRig does not allow clean access to the K3's
ACC DB-15 connector for other purposes such as FSK keying.  Sure, the
connector can be opened to access pins, but it requires a wiring break-out,
leading to yet a further rat's nest of cabling.

 

To help deal with the cabling issues, I am replacing the external PR6 with
the new KXVB3 board.  Next, a KIO3B board will be added when it's available
to existing K3 owners.  That should eliminate the external sound card
interface and clear up much of the cabling mess, but not all of it.  

 

The Holy Grail is an Ethernet interface that includes (optional) integrated
RemoteRig hardware - just one interface board [e.g., KIO3E(thernet) board]
that manages K3 Ethernet connectivity with or without RemoteRig attributes.
Don't need Ethernet? Then don't get the board.  Since the RemoteRig hardware
is mature and consumes little circuit board space and DC current, perhaps it
would be worth opening up a discussion with RemoteRig's designer since
Elecraft already has a close relationship with Microbit.I know rear
panel real estate is a concern, so it won't be easy to add yet another
connector without adversely affecting other connectivity.  Thoughts?

I saw the comment about the rats nest of wires we have behind out

Re: [Elecraft] K3/K3s Ethernet Interface

2015-07-19 Thread Dr. William J. Schmidt, II
Yes you can use it one of two ways... in TCP mode, there is a small driver 
loaded on your PC that creates a pseudo RS232 port on the computer that all 
your existing software connects to.  Your software thinks it's talking to your 
radio via RS232... but really that is an emulation that gets ported over the 
Ethernet to the radio (where the Ethernet to RS232 server is) and deconstructed 
into RS232 (RXD and TXD) with DTR and RTS for keying.  Your computer can be 
right next to your radio or half way around the world and the radio will never 
know the difference.  Latency is not a problem.

Second mode is WEB server where the radio is emulated in web pages in the 
onboard web server (eg web page looks like the radio).  You can change any 
parameter in the setup or knob on the radio that you could via RS232.

No security is provided.  Nor is there with the FLEX, Ten-tec, or any other 
radio that has an Ethernet connection currently.  I just use a Netgear firewall 
and VPN through it securely.

The soil conductivity on most high mountaintops IS just plain awful. :) 
BUT -- there's nothing like having your antenna on a 3,000 ft tower, 
even if it is made of rock. When you get there, almost anything works, 
and anything decent works really well.


W6GJB has a go-kit for his KX3 that includes a simple telescoping 
antenna that mounts to a tripod with a coax connector in the base, and a 
couple of wire radials that can be tossed into surrounding vegetation if 
there is any, or lay on the ground if there is not. Last summer as a 
site survey for FD, we set that up at Berryessa Peak (70 miles N of SF), 
and in about ten minutes, made three contest-style CW Qs to JA, SA, and 
the east coast of the US.


Spiderbeam sells a 40ft (12M) telescoping fiberglass pole that weighs 7# 
and collapses to 3ft-10in. About $135 with shipping from TN).


For about the same price, there's the DK9SQ 33 ft carbon fibre pole that 
collapses to 3.8 ft and weighs 2.2#. I used one of those with my K2 at 
my old Chicago club's annual QRP night in a local park. A photo is on my 
qrz.com page. I taped a #22 wire to it, wedged it between the seat and 
the top of the picnic bench (at roughly a 45 degree angle), and laid out 
two more wires as radials. Running 5W on 30M, I easily made a half dozen 
QSOs, including one that was a Caribbean station running a pileup.


I agree that the Alex Loop, as well as home brew versions of it, can be 
a pretty decent backpacking antenna. W6GJB also has one of those.

The Genesun GV-series controllers are RF quiet, and their MPPT design

KD5NDB is a silent key and I do not know of anyone selling his

schematic drawing which I can E-Mail to anyone that wants to 
build this solar regulator. One advantage of his circuit is 
that it makes no RF noise. Many other SOLAR REGULATORS make 
serious RF noise.

Re: [Elecraft] Miniature self-supporting HF antennas

2015-07-19 Thread David Gilbert


It's not going to radiate any lower than the horizon, and that kind of 
low angle is extremely useful for long distances.  That can be 
appropriate even for QRP, although it might be more propagation 
dependent versus making some high angle short skip contacts.  If I want 
to see how far I can work when backpacking, I'm going with a vertical 
unless the ground conductivity is just plain awful.

KT5X believes [and I don't disagree] that vertical ground planes on 
mountain tops tend to radiate downhill which isn't real useful.  If 
you're above the timberline, you're probably on a mountain.

Re: [Elecraft] K3 Below 500 KHz RX Antenna

2015-07-19 Thread Merv Schweigert
Dont overlook perhaps an antenna you already have up,  I use an 80 meter 
dipole thats
fed with open line,  I short the open line at the shack and feed that 
into the receiver,
I have copied the east coast many times from Hawaii,  and of course all 
the other guys
between,   up to Alaska,  thats on 475KHZ.  Both CW and WSPR.  No preamp 
used.


So if your wanting to just listen and get an idea of whats there, maybe 
check your present
set up,   coax fed dipole would work the same if you short the coax at 
the shack end.

Good, Fast, Cheap, pick two.  At least that's what I told the 
General officer who wanted everything.  We didn't get the job, thank God.


An active E-field probe is probably the optimum, unless you have a lot 
of room and time.  Small mag loops will work too, but often require a 
preamp
