Re: [Elecraft] Operating temperature range ( second attempt)

[kev...@coho.net]

This may not be applicable to the K3 but I have used the K2 below 32 F.  
My K2 has the 100 watt amp with a built in fan.  The fan got confused 
and stayed on.  The algorithm to adjust the fan speed did not understand 
a negative Celsius temperature.  With the fan blowing my fingers got 
pretty numb and kept sending more dits than desired :)

You should directly contact the Elecraft factory for this. However, as I 
recall, the K3 and KX3 are designed to operate over an operating temperature 
rating: 0 – 50 °C.

Unfortunately the guys who wrote the rules failed to understand the

which we have been laboring for as long as I've been a ham. It was Henry

2003-4. Henry is a VERY smart guy, one of many who came out of Bell Labs.

The standard word "paris" has 48 elements.  That makes the baud rate

ITU defines the "Necessary Bandwidth" for CW as 3 or 5 times the speed
in bits per second (baud rate) where 3 x is for "non fading circuits"
(where the waveform does not need to be so "sharp") and 5 x for "fading
circuits."See:
http://http://life.itu.ch/radioclub/rr/ap01.htm part B.
The same table is found in Title 97, Part 2 of the Code of Federal
Regulations (FCC Rules) as §2.202(g)

The constant 'K' sets the minimum bandwidth needed/occupied for the two
recognized cases.  Occupied bandwidth in excess of K=5 (or 400 Hz for
100 WPM) would be unacceptable due to improper keying waveforms or
distortion in the RF stages.

Yes, but that's RX bandwidth, VERY different from occupied bandwidth. 
The issue is RX bandwidth is the TIME (phase) response -- every change 
in amplitude is accompanied by a change in the phase response, that that 
phase distortion (remember, phase is time) blurs the code elements 
together.


So you need more bandwidth for super high-speed CW because you need to 
shorten the rise and fall times. 


You need more RX bandwidth, for the reason described above.


But the occupied bandwidth doesn't change as you vary the speed.


Right. Occupied bandwidth is your "footprint" on the band -- how much 
your signal is spread out.

Re: [Elecraft] Battery requirements for NPOTA activation withKX3/KXPA100

[Igor Sokolov]

I have experimented with LiFePo4 batteries feeding KX3/KXPA100 in contest 
environment where duty cycle is about 50% for TX. For SSB the current draw 
is a bit higher then for CW. 25Ah battery lasted 4 to 4.5 hour with 100 W in 
the beginning and dropping to 50-60W out in the end of the cycle. For SLA of 
the same capacity you will probably have  half of that time. With 2x 60W 
solar panels added to the mix I get between 6 to 8 hours in semi sunny 
weather. I have ended up with a pair of LiFePo4 25Ah each (about 2 Kg each) 
which allow full day of operation. Again if you use SLA instead of LiFePo4 
you will need at least 100 Ah.

Subject: [Elecraft] Battery requirements for NPOTA activation 
withKX3/KXPA100




Hi folks,
I know this has been asked and discussed before but I can’t seem to get a 
handle on a clear-cut answer …


I am going to do a SSB NPOTA (National Parks on the Air) activation with 
my KX3/KXPA100/PX3 on battery power. It has been in the works for a while 
with a special use permit required by the NPS.


How much battery capacity do I need if I want to run full 100 watts? For 
planning purposes, I am assuming a 6 hour activation with a (highly 
optimistic I know) 60 QSOs per hour.


The PX3 will be powered by a separate LiFePo 4.8 aH battery, it will do 
just fine. My concern is the amount of draw I will need to last the 6 
hours. With an inline (Hobby King) HK-010 Power Analyzer, I see a max 
current (KX3/KXPA100 combo) of about 8 amps and about 80 watts during a 
QSO. The QSOs varies between 50-80 watts on transmit.


I also know that once I am spotted, I can drop the power down to maybe 
75-50 watts to save some battery juice.


I have 2 12v-18aH SLA batteries at the ready, am I woefully underpowered? 
If you have any real-world experience or tips, it is most valuable and 
appreciated. You can contact me offline at dave dot esquer AT gmail as 
well.


Thanks,
Dave, K6WDE

[Elecraft] Things to Come

[Dauer, Edward]

I was about to reply to a couple of posts on the UI topic when I read
Eric¹s post (below), which makes a point I would underscore.

Since many of us (not surprisingly) share aviation and hence avionics
experience as well as amateur radio, that experience may be useful in
reflecting on the topic of UI for amateur gear. As Eric implies, and as LS
also points out, the question is not either-or.  There are some functions
for which soft keys are better than layered menus, and those better than
dedicated buttons and knobs, and those better than or worse than touch
screens.  For example, I think that during critical phases of flight I
would not want to replace the tactile feedback of a throttle lever with a
screen-based input; I like having the gear lever feel like a gear lever
when I grab it; and while this one I might be willing to change, I think a
flap control should feel something like a flap.  But navigation is
cerebral rather than tactile, and for that an intuitive layer of soft keys
seems just right.  On the other hand, if I need to kill the strobes
because I¹ve just entered IMC (clouds, to the earthbound), I¹d like to
stab at a known, dedicated, and unprogrammable button that I¹ve mentally
marked IF YOU CAN¹T SEE, PUSH HERE RIGHT NOW. Point - touch screen isn¹t
better or worse than any of the alternatives.  It¹s either better or worse
for some functions than any of the alternatives, but not for others.
Maybe VFO A knobs are like flap controls?   My point in raising the
experience of avionics was to say first, that that field seems a bit ahead
of the amateur radio gear field in ergonomic design of similar systems;
and second, that it shows that design choices shouldn¹t be driven by
global preferences.  No surprises there, eh?

Re: [Elecraft] OT: Decoding high speed CW

[lstavenhagen]

I took 3 FCC code exams: the 5wpm for my novice in 1973, and years later, the
13wpm for the Advanced and the 20wpm for the Extra. But ironically, I think
the FCC removing the code requirement was a good thing for CW in amateur
radio. Now that people aren't forced to learn it and have to use it, and
potentially develop a bad taste in their mouths for it in the process,
they're more attracted to it as another activity they can pursue in the
hobby. Just like the digital modes and so forth. The FCC no longer practices
"mode discrimination" and amateurs are free to use whatever mode they like.

I've heard it said that CW usage has actually gone up since the CW
requirements were dropped, and I believe it. The lower end of 20 meters is
essentially unusable when a CW contest is going on, or at least it's good
thing I have rigs like my K's that can handle 800 S9+30db sigs every kc in
the band hi hi.

So to bring it back around to Elecraft, I should think the incentive to
continue to support strong CW capabilities in the K rigs will continue to be
there for quite a long time

[Elecraft] K3 & K3S are GREAT radios!

[Rich - K1HTV]

Gary,
   Congrats on working VK0EK on 160M with your K3S. Yes, it is a great radio. 
I'm using the K3 with the synthesizer upgrades made to both main and sub 
receivers. A few weeks ago I worked a super pee weak 4S7BRG on 40M for #313 on 
that band with 100 Watts and a wire antenna. When the rare VP8STI (So. 
Sandwich) and VP8STG (So. Georgia) DXpeditions came on the air, my barefoot K3 
again did its thing, adding Topband countries #226 & #227 to my 100 Watt 160 
Meter totals. 

The K3 with its 200 Hz roofing filters, DSP further reducing the bandwith to 50 
Hz, then the APF further tightening the BW to a sharp 5 Hz peak made it 
possible to hear those weak signals through my local noise. Having K3S 
transceivers on the Antarctic end of the path sure helped those 160M QSOs make 
it into the K1HTV log.

Now I need to focus on working VK0EK and FT4JA for even more Topband DX with my 
K3, a great radio!

Rich - K1HTV

I just worked the VK0KE on 160 last night.
I honestly, to God do not think that any

have heard the incredibly diminutive

Re: [Elecraft] OT: Decoding high speed CW

[Bill Frantz]

In a desperate attempt to make this subject at least vaguely on 
topic, note that future CW use is important to the future 
requirements for ham radios. If new hams aren't interested in 
CW, then good support for CW will become less important, 
particularly as older ones leave the hobby.


There are a couple of things which give me hope for the 
continued use of CW:


CW is the easiest mode to use for DXCC. Between the large number 
of stations active on CW, and CW's ability to work in bad band 
conditions, I think it will continue to attract users. Digital 
might be a contender for bad conditions, but it seems to me the 
QSO rate is always slower for Digital vs. CW.


The number of licensees in the US continues to climb in all 
three license classes. Even if we assume that all the 
technicians are only interested in VHF/UHF FM for emergency 
services use, we still have growth in generals and extras. These 
people will be using HF for contesting, among a myriad of other 
uses. Many contests have incentives for CW in their scoring systems.

I know about KSM, but that isn’t a commercial enterprise or even a nonprofit 
full-time job.

My dad volunteered as a blacksmith some weekends at the old Texas exhibit at 
the Fort Worth Zoo. But it wasn’t a job. He really enjoyed it.

Ron, this is what I recall from the FCC commercial radiotelegraph Morse exams:

Third Class and Second Class:
20 wpm plain language receive for five minutes, perfect copy required for 100 
consecutive characters (one minute).
20 wpm plain language send (straight key use mandatory) for up to five minutes, 
perfect sending required for 100 consecutive characters (one minute).
16 wpm random character groups receive for five minutes, perfect copy required 
for 80 consecutive characters (one minute).
16 wpm random character groups send (straight key use mandatory) required for 
up to five minutes, perfect sending required for 80 consecutive characters (one 
minute).

The test for First Class was as described above at 25 wpm plain language and 20 
wpm code groups.

Written exam elements 1, 2, and 5 were required for Third Class.
Written exam elements 1, 2, 5, and 6 were required for Second Class and First 
Class.  Element 6 required some short answer and schematic drawing.

Everyone generally took the exam for element 8 Ship Radar as well.

I passed the Second Class exam almost 40 years ago, but my old study books for 
the exam indicate that the tests listed above were in place even before WWII.  
AFAIK, the only change occurred in the early 1990s when the FCC began giving 
credit for all of the above if the candidate held an Amateur Extra license.  
That, of course, wasn't even remotely equivalent...I guess the FCC just got 
lazy.

I took several ham Morse exams at the FCC in the late 1960s and early 1970s.  
Contrary to some claims otherwise, I do not ever remember the 13 wpm test being 
random code groups on a ham exam.  That is far more difficult than plain 
language to a ham new to Morse.

A good practical capability to function at 25 wpm was sufficient for starting a 
merchant marine radio officer career.  Until it all disappeared on 12 July 
1999, the MF Maritime Morse band (410 to 535 kHz) was the most magical spot in 
the entire radio spectrum...especially at night!

I got solicited by the Radio Officer's Union in 1991...there weren't enough 
radio officers to man the US-flag merchant vessels that got re-activated after 
Desert Storm.

What I really regret is that during my US Navy days there was nothing so small 
and capable as the Elecraft K1.  I could have had a fine time *ashore* with a 
K1.

Manual Morse is still alive in the Maritime Services through Public
Coast Station KSM, the former RCA Coast Station KPH,  with receivers in
Point Reyes, CA and transmitters in Bolinas, CA.  It is owned by the
National Park Service and operated by the Maritime Radio Historical
Society with properly-licensed operators.  We operate on weekends, on
genuine restored coast station equipment, and there are still several
vessels that use Manual Morse for traffic.  We accept message traffic at
no cost - we're funded by grants from the Park Service and member
donations.  And we still keep "Silent Period" watch on 500 KC as in the
"good old days".  We also operate a ham station on several HF bands  -
at full legal power - licensed as K6KPH but using maritime calling and
traffic procedure.   See:  www.radiomarine.org

The military still trains a small cadre of Morse intercept operators -
now rated as Crypotologic Technicians - because "the others" still use
Morse for various purposes and we need to know what they are up to.  It
is not used for tactical or command communications. See:

[Elecraft] Attaching a whip to the KX3, HT-style or table-top (right angle)

[Wayne Burdick]

Hi Gerry,

If I'm using the rig HT-style (/PM, or pedestrian mobile), I just connect the 
whip directly. The KX3's BNC connector is rigidly attached to the right side 
panel, with a D-shaped bushing so it can't rotate, and a flexible wire from the 
BNC's hot lead to the PCB. So you won't hurt anything by doing this. Any 48" 
long telescoping whip with a base loading coil and BNC will work, though as I 
mentioned, I'm partial to the MFJ 18xxT series.

For picnic-table-syle operation, I've been using the whip with a tiny home-made 
tripod. It has two female BNCs: one at the top for the whip, the other at the 
bottom at a right angle so it can attach directly to the radio. The radio 
connection can use either a double-male BNC adapter or a length of coax. The 
height is adjustable to match the height of the BNC on the radio.

The tripod has three legs that fold up and out of the way, resulting in a unit 
that's less than 6" long and 1" in diameter. Weights only a few ounces.

If anyone besides me is interested in the tripod, maybe we'll make it into an 
Elecraft product :)

73,
Wayne

Re: [Elecraft] IC-7300 video - things to come

[Eric Swartz - WA6HHQ, Elecraft]

As a private pilot I fly with a Garmin GTN750 touch-screen GPS NAV/COM in a 
Cessna 182. Its powerful and quite intuitive to use, even in turbulence. (They 
included ridges along the four screen sides when needed to steady your hand.) It 
actually reduces the amount pilot load and time spent looking inside the cockpit 
when used properly - Though you can certainly abuse it dangerously if you treat 
it like a video game and forget to look outside the cockpit..   I wouldn't go 
any other way now.   (And I came from a full-on knobs based flight environment 
prior to that.)


There are great touch-screen avionics implementations and horrible ones. The 750 
is a good one and world's above many others.


I think for future ham radios and similar product designs, what will be 
important is meshing the correct balance between traditional hard knobs and 
buttons with unique touch-screen features (display and input). The overall goal 
should be to balance the user interface between the touch-screen and 
knobs/buttons for ease of use without unintended confusion while adding unique 
touch-screen display and easy to use input features.


As a side note - I use the remotehams.com free remote software with the 
K3/0-Mini and a laptop to remote my home K3S, KPA500 and Rotor. Interestingly, 
the little h/p satellite 360 convertible laptop/tablet has a touch screen, which 
I use for many functions like rotor control, amp control/status etc, but I like 
it combined with the K3/0-Mini's knobs and display for regular intuitive use, 
versus using it only for 100% computer based remote control.

Re: [Elecraft] OT: Decoding high speed CW

[Walter Underwood]

As far as I can tell, Morse is entirely a hobby now. Maritime radio stopped 
monitoring Morse on 12 July 1999. I did some searches and I don’t think the US 
military offers a Morse skill rating now.

You can make a living blacksmithing, but not with Morse code.

This takes nothing away from Morse as a hobby. Or from blacksmithing — my 
father was an amateur blacksmith.

Re: [Elecraft] [K3] CW Speed & bandwidth (was Tokyo Hy-Power HL-1.2KFX amp interfacing (to ALC or not to ALC?))

[Fred Jensen]

Ummm ... not exactly true but not exactly not-true either.  Occupied BW 
is a function of bit-rate [well, technically, number of signal 
transitions in a unit time, but they're closely related].  Fairly basic 
physics ... or I guess that's information theory now.  The faster you 
send, the wider your signal will be, guaranteed, you can't escape it. 
Like trying to drive faster than light, discarding angular momentum, or 
resigning from Linked-In.


Waveshape also affects occupied bandwidth, although the amount it 
increases the BW carries no information ... except for the useless fact 
that the dude with huge key clicks is still up there 15 KHz.


At "normal" CW speeds, aka D4C, the BW increase due to speed is hardly 
noticeable. With poor wave shaping, it is VERY noticeable, and 
information-free.

So you need more bandwidth for super high-speed CW because you need to
shorten the rise and fall times. But the occupied bandwidth doesn't
change as you vary the speed.

My memory is 16 WPM code groups and 20 WPM plain text for the Second
Class.  The one year at sea was for the endorsement permitting  the
person to be the sole operator on cargo ships.  The requirement to sit
for the First Class exam was one year or more experience handling Public
Correspondence (message traffic to and from commercial ship or shore
stations excluding most military experience).  Passenger ships required
two or more operators, one of whom had to hold a First Class license
acting as "Chief Operator".

The code requirements for the Second Class have been carried over for
the "combined" lifetime Radiotelegraph Operator License.  The FCC will
no longer issue  First Class Licenses because Manual Morse is no longer
required for safety and distress traffic in the Maritime Services now
that the satellite and SSB-based GMDSS is in operation and there is no
need for a "Chief Operator" on ships..

I finally got my Second Class before the "cut-off", one of the last 8 so
issued.  It gets renewed only once in 2018 and then it goes "lifetime"
losing the Second Class designation.

Re: [Elecraft] OT: Decoding high speed CW

[Ron D'Eau Claire]

In the 1950's the U.S. 2nd class commercial Radiotelegraph license exam
required 20 wpm sending and receiving. Receiving was 5 character random
groups that included all punctuation and most of the special characters you
see above the numbers on a keyboard. After 6 months of sea duty as an
assistant radio officer, one could apply for a First Class license that
required the same but at 25 wpm. I don't recall how long we had to copy,
just the elation LS experienced at passing, Hi!

In our work we had to have excellent character-by-character copy, usually
pounding keys on a mill. Contesting is a bit like that except that in a
contest one has a planned format and very short message as contrasted so,
say, copying press (news) for half an hour at a time. 

I'm not surprised at the speeds one hears in contests. When rag-chewing,
however, I seldom find stations running more than 20 wpm, often much less.
And I often just "read the mail" in my head listening to CW rag chews while
puttering around the shack. 

IMHO, the different uses for CW lend themselves to different learning
techniques. I have met good, competent contest operators completely unable
to have a QSO that is not a contest exchange. They simply cannot think
conversationally at a key or paddle. On a keyboard they often revert to a
brag tape and must QRT when it runs out. And of course, everyone seems to go
through a bit of a learning curve to copy CW in their head.   

After all these years 99% of my operating is still CW. I joke that I spent
so much time learning CW that I am determined to get as much value from the
effort. (It's not entirely a joke, Hi!)

Excellent points, IMO. I took both types of code tests. For my novice in
1973 when I was 10 years old, it was the random groups at 5WPM format. IIRC,
I achieved the 1-min-solid-copy requirement by some miraculously slim
margin.
It was something like 2 or 3 characters and I remember being extremely
relieved and elated at the accomplishment. 

For the Extra, years later, it was when the content was a regular old QSO,
so I had virtually completely solid copy of the whole thing; the written
test was nearly my downfall in that case (I passed with like 71% or
something). 

Finally, IIRC, licenses like the commercial radiotelegraph license had even
more comprehensive requirements - something like 5 minutes of random groups
at 20wpm, 5 minutes of plain language at 25wpm, or something like that,
depending on what class of license you were going for. Pretty tough! 

So yes it seems to be well established that plain language is quite distinct
from random letter/number groups with respect to copy speed. And it was
tested accordingly, or at least in my opinion it was. 

Fortunately, now that CW isn't required at all has seemed to, ironically,
started a revival in CW. The CW portions of the bands do seem to still be
more sparse than the SSB portions, but they're still there

Re: [Elecraft] Battery requirements for NPOTA activation with KX3/KXPA100

[Grant Youngman]

SSB is low duty cycle. Even if you have processing cranked way up, with 80 
watts out peak, your average power won't be any where near this level. And you 
do have to stop talking and listen, fetch a beverage, visit the nearest shrubs, 
right? :)

I think you'd easily do 6 hours with what you have -- and have a good bit of 
battery left over.

Re: [Elecraft] Battery requirements for NPOTA activation with KX3/KXPA100

[lstavenhagen]

I've looked at this too, given that I'm /P almost 100% of the time now and
have considered various QRO options. Unfortunately, I've yet to find a QRO
solution that doesn't involve something semi-permanently mounted in my
truck. Either a deep-cycle AGM or a high capacity LiFEPO4 in the spare
battery tray under the hood with long heavy cables is about the best I've
been able to come up with.

If I keep it at 10 watts or less, though, I can actually carry it a short
distance (and of course its easily transportable in the vehicle). My K3 and
K3S, for instance, will run a good 4 or 5 hours on my 9AH AGM batt, though
less than that with a lot of transmitting. The K2 would run all day on the
same batt

So that might be required in your case too? Eg. a YellowTop 12V deep cycle
in the vehicle or an equivalent LiFE 12V... Sorry, I know that's not much
help, but I'm kind of in the same boat hi hi.

Re: [Elecraft] IC-7300 video - things to come

[Ron D'Eau Claire]

A couple of airline crashes have been blamed on the pilots being unable to
touch the right spots and read the "gages" in modern all-glass cockpits when
the aircraft was experiencing severe turbulence or vibration from engine
problems. And they happened while one pilot was able to concentrate (as much
as possible) on the display while the other one was flying the plane. In one
instance it led to the crew shutting down the wrong engine which led to a
crash after they discovered the error too late to restart the good engine
before running out of altitude.

Those of us who have aging, shaky hands don't even need the turbulence,  our 
own brains conspire to make touch screens difficult to operate.   The "soft 
buttons" like the P3 and PX3 have work great, though.  They allow the finger to 
touch the button without activating it so you can tell that you are pressing 
the right spot.

Because of my essential tremors,  I will not buy a touch screen radio.  Sorry, 
Icom!

Re: [Elecraft] Battery requirements for NPOTA activation with KX3/KXPA100

[Fred Townsend]

Councilor: LOL if you are looking for precise information from imprecise data. 
Best I can do is a WAG.  If you take your ah rating say 36 and multiply by the 
battery voltage say 12, we have 432 watt hours. Divide by 2 to account for 
efficiency losses and we have 216 wH and finally divide by your transmit draw 
80 watts and we have  2.7 transmit hours. Does this help? Remember this is a 
WAG (Wild Assed Guess).

Hi folks,
I know this has been asked and discussed before but I can’t seem to get a 
handle on a clear-cut answer …

I am going to do a SSB NPOTA (National Parks on the Air) activation with my 
KX3/KXPA100/PX3 on battery power. It has been in the works for a while with a 
special use permit required by the NPS.

How much battery capacity do I need if I want to run full 100 watts? For 
planning purposes, I am assuming a 6 hour activation with a (highly optimistic 
I know) 60 QSOs per hour.

The PX3 will be powered by a separate LiFePo 4.8 aH battery, it will do just 
fine. My concern is the amount of draw I will need to last the 6 hours. With an 
inline (Hobby King) HK-010 Power Analyzer, I see a max current (KX3/KXPA100 
combo) of about 8 amps and about 80 watts during a QSO. The QSOs varies between 
50-80 watts on transmit.

I also know that once I am spotted, I can drop the power down to maybe 75-50 
watts to save some battery juice.

I have 2 12v-18aH SLA batteries at the ready, am I woefully underpowered? If 
you have any real-world experience or tips, it is most valuable and 
appreciated. You can contact me offline at dave dot esquer AT gmail as well.

Re: [Elecraft] Battery requirements for NPOTA activation with KX3/KXPA100

[Nr4c]

I think you'll draw a lot more than 8A at 100 watts. 

Also note that to get 100 watts from this setup will require a bit more than 14 
volts I think. I ran my PS at 14.5 or better to make it. YMMV!  

You're gonna get a lot responses on this query, so be prepared. 

Your best friend here is going to be AMPHOURS. The more you have the longer 
you'll be able to keep the voltage drop down. When the voltage drops too low 
the KX3 will drop the power. You might consider starting st 75 watts and drop a 
bit when the pileup gets going. 

Where at you going. And have your spotters note the park or Unit ID.

Re: [Elecraft] IC-7300 video - things to come

[Lynn W. Taylor, WB6UUT]

In my mind, I have a totally different picture of this.

I don't see a panadaptor, or windows, or pop-ups.

I see a front panel that looks very much like a KX3 or a K3, with 
buttons drawn on the touch screen.


I see some ability to "turn off" buttons that I would never use, and 
make other buttons bigger.


Mostly, I see a way for Elecraft to add a button for some whiz-bang new 
feature, instead of having to squeeze more functions in without being 
able to add a button.

The constant 'K' sets the minimum bandwidth needed/occupied for the two

For me, even if touch-screen UI's were written for old people like myself, hi

The infantile part of it being primarily in its application, not so much
just the mere fact that TS technology itself new and still in "1.x"

products is when I recognized that the T-S train had skipped off the rails -
I wondered if anyone at Garmin's aviation products division had ever even
flown in a light aircraft before? And Apple continues to threaten to go
all-iPad with every release, though I suppose if sanity could return
somewhere Apple might be the most likely first place for it to do so.

In amateur radio, my opinion is mixed. I can see myself having fun with T-S
on a panadaptor, but the smile kind of fades from my face when thinking
about using the radio in general on a greasy thumprinted, fussy screen with
windows popping up all over the place 

All things being equal, though, I prefer knobs on a radio and not having to
wash my hands with toilet bowl cleaner before I use it hi hi. Like I said,
maybe a separate screen for the T-S spectrum scope, but everything else
relegated to good ol' knobs hi hi.

OT... but my mother, back in 1942, after 
divorcing her abusive Ex (One of the main 
architects of the Golden Gate Bridge), 
bicycled by herself from Philly to Key 
West, by herself, took a ferry to Cuba, 
bicycled around the island for a month 
before returning to the mainland to take 
the train back to Philly.

For those of you on Facebook, here she is

Re: [Elecraft] [K3] CW Speed & bandwidth (was Tokyo Hy-Power HL-1.2KFX amp interfacing (to ALC or not to ALC?))

[Vic Rosenthal 4X6GP/K2VCO]

The relationship of bandwidth and speed is that for given rise/fall 
times, increasing speed will reach a point when the code elements blur 
together.


So you need more bandwidth for super high-speed CW because you need to 
shorten the rise and fall times. But the occupied bandwidth doesn't 
change as you vary the speed.


The K3's keying waveshape and rise/fall times (the shape is important, 
not just the time) are good for far faster CW than I can send!

No, because even the best rise/fall waveform has SOME harmonic content,

I'm not the one here with the most money, 
I'm absolutely positive of that, but that 
said; I can buy any rig I want and the 
dollars spent wouldn't in any way affect 
me, or anything I do in the future. 

I just bought a K3S because of the many 
things it represents but I'm not a martyr 
to buy USA when something else is better 
or, buy something wonderful that is 
software based only like the Flex 6700; I 
bought the K3s because to my discovery, it 
is the finest radio out there. Yes, this 
is the Elecraft reflector so most of us 
are already on board but I bought this 
radio (I upgraded from an updated K3) 
because it is to me, the pinnacle of 
today's equipment.

I just worked the VK0KE on 160 last night. 
I honestly, to God do not think that any 
radio I have ever owned before, save the 
K3 with the updated synthesizer, would 
have heard the incredibly diminutive 
signal that I heard reply to me. I was the 
first NA station to post them in the

the quality of this radio. The K3s Rocks.

Interesting discussion.  I'm not (yet?) a touchscreen fan for radio
control, especially during a contest.

That being said (cough, cough), I am lately having some fun designing my
own touch screen interface for an ANAN-100D.  Someone came up with the
software glue to recognize and map any midi control to any CAT command for
the OpenHPSDR radios (including Apache/ANAN) and there's a $5 TouchOSC
Android application that allows you to quickly design from scratch any type
of virtual midi controller on an Android or iPad tablet.  All this has been
made possible by the Open Source nature of the software.  So instead of a
macro keyboard, I can use my 7 in tablet.

The upshot is that I might be a fan of touchscreen if they were user
configurable.  I really like the idea of users being able to design their
own front panels.

WRONG! CW speed has NOTHING to do with bandwidth, which is determined by 
RISE and FALL times of the keying waveform and distortion in the RF stages.


I strongly agree that amplifier output power should NEVER EVER be set 
using AGC. It should ALWAYS be set by setting drive power for the 
desired output, but always staying below the power level that increases 
amplifier non-linearity (distortion).


The use of AGC to set amplifier power has been considered a bad thing 
for at least 35 years -- the operating manual for my Ten Tec Titans says 
not to use it that way. If you look at the schematics (in the manual) 
you'll find K4XU's initials on them. Thank you, Dick!


The ONLY good way to use AGC is to protect the amplifier when something 
fails in the antenna system (by reducing drive from the transceiver). 
Yes, some rigs produce power spikes at the beginning of a transmission. 
Those are bad rigs, and have no business being used to drive a power 
amp! If you want to run an amp, buy a REAL radio. :)

I may have missed something in this discussion but I question what is different 
from using a touch screen or the buttons on the radio as we have now?  I 
operated a considerable amount of time in the WPX SSB test last weekend using a 
K3 and about all I ever changed was the tuning knob and the width control.  And 
maybe he NR and NB a couple of times. Using N1MM+ I did not even need to change 
bands using the radio controls.

that for a contest's worth when you have 
shoulder issues. If you don't have them

Have a touch pad on the table, You'll be

Re: [Elecraft] OT: Decoding high speed CW

[lstavenhagen]

Excellent points, IMO. I took both types of code tests. For my novice in 1973
when I was 10 years old, it was the random groups at 5WPM format. IIRC, I
achieved the 1-min-solid-copy requirement by some miraculously slim margin.
It was something like 2 or 3 characters and I remember being extremely
relieved and elated at the accomplishment. 

For the Extra, years later, it was when the content was a regular old QSO,
so I had virtually completely solid copy of the whole thing; the written
test was nearly my downfall in that case (I passed with like 71% or
something). 

Finally, IIRC, licenses like the commercial radiotelegraph license had even
more comprehensive requirements - something like 5 minutes of random groups
at 20wpm, 5 minutes of plain language at 25wpm, or something like that,
depending on what class of license you were going for. Pretty tough! 

So yes it seems to be well established that plain language is quite distinct
from random letter/number groups with respect to copy speed. And it was
tested accordingly, or at least in my opinion it was. 

Fortunately, now that CW isn't required at all has seemed to, ironically,
started a revival in CW. The CW portions of the bands do seem to still be
more sparse than the SSB portions, but they're still there

Re: [Elecraft] [K3] Tokyo Hy-Power HL-1.2KFX amp interfacing (to ALC or not to ALC?)

[Edward R Cole]

I thought the best way to drive an amplifier was to increase drive 
until output no longer increased proportional to input; eg output 
increases 3-dB with an 3-dB increase in drive is linear.  Isn't the 
point the increase drops 1-dB the upper limit?


That is how I determine best drive level on VHF linear amps.  Most 
folks run up drive until they reach saturation (no change in output 
with increased drive) and then operate SSB there.  No wonder their 
voice peaks are cut off causing splatter.  BTW high speed CW should 
not be run at saturated power, either.  CW actually has bandwidth 
though at 5wpm probably not measurable 


ALC was a good concept that never worked very well (negative feedback 
gain control).  ALC meter on the K3 is useful for setting audio drive 
just to the point ALC begins to act (four bars with 5th flickering). 
But I guess all of you know that - right?

Re: [Elecraft] OT: Decoding high speed CW

[Edward R Cole]

LD,

That is why it was so hard to pass the CW tests back in the 1950's 
taking before the FCC because the test did not have any real 
words.  The entire 5 minute code test was five random character 
groups, not all of which were letters or numbers and you had to have 
one minute perfect copy to pass.  I never managed to pass at the FCC 
in Detroit with the unsmiling stern FCC employees that looked like 
they were FBI ready to haul you off to Cuba or somewhere? ;-)


So imagine my pleasure taking my 13wpm at the Anchorage FCC office in 
1982 with happy friendly faces and copying samples of an actual QSO 
with real words and only having to answer seven multiple choice 
questions about the test correctly - absolutely no comparison with 
the CW "inquisition" of the 1950's.


BTW I did get to the point that I recognized common words like "CQ", 
"de", "73", "name", "RST", "QTH", etc.  They became words in the CW 
"language".  Too bad CW isn't sent in Latin; I took two years of that 
in HS .
Only good that did me was understanding the priest at a Catholic Mass 
back in the days they still spoke in Latin.  Of course I can pick out 
a few words in Spanish and French and several other languages that 
have Latin base (like English) - .  Pretty hard to 
copy CW in Yupik Eskimo.


Good points about CW becoming a language.

That would explain why, for example, your copy speed will drop (sometimes
dramatically) when the content is blocks of random letter/number groups
instead of plain language, or if you're reading the mail on a QSO in another
language like Spanish or German (and you don't speak those languages).

Your comment is appreciated. I am in your camp but we are a bit older and happy 
with our
current campfire. Younger hams and new hams might be very engaged with a 
touchscreen
interface. The “over $8 K” product managers seem to have peaked lately in their

Method Two: Put a spade lug on a short piece of wire, slide it under the 
spade lug, put a single Power Pole on the other end. Then add Power 
Poles to one end of the counterpoise wires.


I use method two. In the shack, it's used to bond the KX3 to the rest of

I also carry a BNC to Pomona (dual banana) adapter, which makes it easy

Re: [Elecraft] [K3] Tokyo Hy-Power HL-1.2KFX amp interfacing (to ALC or not to ALC?)

[Alan Geller via Elecraft]

I have a THP HL-1.2KFX that I used before the acquisition of my K3. It is a 
reliable and resilient amp and I have had the ALC connected to the K3 for a 
year. However
I tend to take Don Wilhelms advice and there have been times when the ALC and 
SWR inputs to the AMP’s logic seem to fight each other, so I just disconnected
the ALC and will report any issues….silence = happiness.

I mourn the the shutdown THP after the earthquake/floods. It was a terrific 
company with a lot of great products with leadership in the mould of Elecraft.

that for a contest's worth when you have 
shoulder issues. If you don't have them

Have a touch pad on the table, You'll be

I'm always terrified of losing the thumbscrew in the grass. I wish MFJ made
these with a built-in right angle and a binding post, or even just a bolt

Use one of the KX3's thumbscrews. We relieved the paint on the chassis at these 
points so you can use them for counterpoise wires or ground.

Re: [Elecraft] IC-7300 video - things to come

[lstavenhagen]

yep, I totally agree. This would be a TBD item for a UI designer, IMO: to
what degree do we actually replace the tuning knob with touch-screen QSY? Do
we make it capable of just getting into the neighborhood and then the user
has to fine tune with the tuning knob? I.e. a kind of dual-capability
approach. Or do we make it able to do exact tuning, completely replacing the
tuning knob?

Probably one of those things that would have to be developed on a
trial-and-error basis, IMO. One of the hazards of very powerful technologies
- the club can be just as easily turned on _you_ as on your good intentions
LOL.

Re: [Elecraft] Things to Come

[lstavenhagen]

Great post, IMO. One of the takeaways we could have from aviation is the
notion of cockpit resource management (CRM), part of which is the idea that
technology should reduce the workload of the pilot rather than increase it.
Or, if there is an increase, it involves a reduction somewhere else (that
is, learning to use, and paying attention to a heading bug to relieve the
pilot of turning to a heading manually, etc).

In amateur radio UI's, panadapters and spectrum scopes have a really
revolutionary potential in terms of presenting the contents of the band to
the user - you have a full visual representation of which signals are where
and a real potential in terms of QSY to those signals. 

With respect to user interfaces and touch-screen, let me make a couple
observations:
- touch-screen on a panadapter is intuitive; it's a natural way human beings
have evolved to deal with the environment. We see something in our space and
our bodies are tailor-made to reach for them with our hands, fingers etc.
- touch-screen for a menu system is NOT intuitive because a menu system
doesn't present quite the same task to the brain and body. Putting it
another way, it is my contention that a T-S interface offers no benefit to
the user over a mouse or buttons for operating a menu-driven system. 

The iOS touch-screen interface I complained about before is a good example.
When you're in an application where touch-screen is intuitive for a human
being (say scrolling and panning in a web browser) it's heaven. When you're
trying to actually operate the device with T-S it's miserable: windows pop
up all over the place, rotating cubicle things fly around and the device
goes into a catatonic state with no apparent thing on the screen you can
touch to recover it. The Big White Button at the bottom of the device is
your only resort. Horrible!

To sum my comment up: I think it's easy to overreact with touch-screen
technology and try to use it for _everything_: not just the applications
where it's great, but also where it doesn't help or even hinders the use of
the device (re: the distinction I made above). 

So going forward with amateur radio, I think T-S technology should be
carefully considered and not done with the Hog Wild method Apple chose for
the iOS interface. That's where the IC-7300 goes overboard, for example, as
I alluded to in my other post: it overreacts and attempts to use T-S for far
too much functionality in the device. 

If Elecraft goes down that road, I would hope for a more balanced approach,
one that's more suitable for the way humans respond to the environment, when
it contains both natural (i.e. spectrum scopes) and unnatural (i.e. menu
driven systems) items.

My .02,

Re: [Elecraft] IC-7300 video - things to come

[Barry N1EU]

The IC-7300 display has hideous resolution.  It can't even trace curves,
just a bunch of bars.  Reminds me of the original 2002 Orion sweep display.

Whatever Elecraft does going forward, please go to the highest resolution
screen that is available and have the horsepower to draw a beautifully
detailed panadapter trace.  That's why pc-based panadapters are so popular
right now.

I'm skeptical about touch screen qsy.  I can't see how you can quickly get
right on frequency.

IMHO, pandapter-centric visual tuning desperately needs a bandmap overlay
with spotted stations (whether self-spotted or cluster) indicated to be
truly useful.

Re: [Elecraft] IC-7300 video - things to come

[lstavenhagen]

Wayne and Eric are probably already aware of the competition and working on
their own responses, but to me the UI advances I personally like are:

- visual representations of the band: panadapters with spectrum displays,
waterfalls and the like
- being able to easily QSY to items of interest on the representation.
- get rid of the ghastly external computer.

In the old old days, the curmudgeonly command to "listen listen listen!"
meant endlessly scanning back and forth with the tuning knob. Which is
perfectly fine and that's how I do it with my rigs right now, but this is a
whole new technology that can supplement that with a visual counterpart like
"use your eyes!".

So what I like in the 7300 that I think Elecraft could think about moving
towards:
- integrated spectrum scope/screen, rather than an external device
- touch-screen operation for QSY, close examination of segments, etc. 

What I don't like and would hope Elecraft would avoid in a competing
solution:
- messy implementation with all these horrible buttons around the spectrum
scope.
- horrible buttons also respond to touch, making goofs and accidental misses
at the spectrum screen your usual iPad experience when you attempt to use an
iPad for something useful. Screens and rotating things going all over the
place, making a mess. Blech!

So one idea would be a regular knob operated UI for controlling the rig
itself and a separate spectrum screen on the side, for example, that
responds to both knobs and touch perhaps. That way, fat fingers won't
accidentally reset your rig into an unusable configuration like the iPad
interface, but you do have the touch-screen capability at the spectrum
scope, where fat fingers will do the least harm and skillful use will have
the most benefit.

Anyway, some of my ideas,

Re: [Elecraft] IC-7300 video - things to come

[Barry N1EU]

Interesting discussion.  I'm not (yet?) a touchscreen fan for radio
control, especially during a contest.

That being said (cough, cough), I am lately having some fun designing my
own touch screen interface for an ANAN-100D.  Someone came up with the
software glue to recognize and map any midi control to any CAT command for
the OpenHPSDR radios (including Apache/ANAN) and there's a $5 TouchOSC
Android application that allows you to quickly design from scratch any type
of virtual midi controller on an Android or iPad tablet.  All this has been
made possible by the Open Source nature of the software.  So instead of a
macro keyboard, I can use my 7 in tablet.

The upshot is that I might be a fan of touchscreen if they were user
configurable.  I really like the idea of users being able to design their
own front panels.

Re: [Elecraft] ERR KEY

[Guy Olinger K2AV]

Same ole thing...

Always, always, always rule out ALL the programs and stuff ATTACHED to the
K3 before tearing apart your K3. The vast majority of "K3 problems" have
nothing to do with the K3. I'm sure that some day some smart psychologist
will explain why we continue to do that, all evidence to the contrary.

A certain someone said to me once, "It just can't be the programs." I asked
why not. I got a hostile look. "It's the K3, it's always the K3", he said.

It was N1MM and the serial port sharing software, finally put to rest **a
year and a half later**.

I wish that psychologist would get on his horse and explain this worrisome
predilection of ours. Bet it has something to do with needing to blame
someone for our distress.

[Elecraft] Things to Come

[Dauer, Edward]

It may be that part of amateur radio equipment¹s future is already here,
and clearly so in avionics (i.e. the electronic display and control
interfaces for navigation, communication, and aircraft performance.)  One
major feature is the ³softkey² - a mechanical button with no exclusive
function but rather a function defined by the subsystem the screen is in.
We-all have this already in the P3, for example, which allows labelling
two rows of buttons albeit by a selection process that is tedious and very
slow compared to the better avionics systems.  And we have it in
elementary ways in certain of the display functions in the K3 and KX3.  I
can imagine a great deal more of it in amateur equipment, with a large
central display surrounded by buttons and on-screen labels changing with
the subsystem.  It would be far better and more intuitive for
configuration changes than the menu system we have now.  Even in the
relatively simple GA aircraft I¹ve flown I can manage the avionics much
faster than I can operate any amateur transceiver I¹ve seen. Which is a
good thing when you¹re moving at a couple of hundred knots.   Compared to
touchscreens, soft keys are more accurate IMHO; but more important, they
keep the residual PB confined to small areas and away from the main
display.

Re: [Elecraft] IC-7300 video - things to come

[Guy Olinger K2AV]

In a contest, particularly a serious effort at a weekend long contest, the
constant reaching from the keyboard to the front of the rig to operate a
touch screen presents a repetitive motion problem whose outcome is anywhere
between tired and injured. This is why many people use the keyboard to
direct N1MM to QSY up or down instead of using the knob.

Some folks use things like Pig Knob, or a keypad driving macros because it
can be set next to the keyboard and used while still maintaining wrist
support for the tuning hand. For those who have already been injured by
repetitive motions at work, these simplifications may be what makes it
possible for them to operate any extended time in a contest.

Re: [Elecraft] IC-7300 video - things to come

[Brendon Whateley]

Cars went through the patch where everything moved onto touch screens.
Ergonomically, that is a really bad choice. Newer cars are moving back to
having twist controls and buttons for some things that were tried as touch
screen controls. The correct answer is to have common features using real
buttons. Context sensitive buttons mixed between real buttons that are
labeled on a screen of some sort and virtual buttons.

The P(x)3 is a good example where you could use a touch screen in a natural
and useful way. I think smart phones have really advanced how we can use
touch screens. But at the same time, physical controls are really very much
easier to use. For some ideas, look at the interfaces for small aircraft
GPS/Glass Cockpit and similar systems. For some examples:
http://explore.garmin.com/en-US/general-aviation/ Each generation changes
the mix of physical controls, reassignable controls and touch screen
controls. The truth is that some things are better done on a touch screen.
Others with physical controls. And in a light aircraft, when you are in
turbulence... touch screens are really hard to use!

We are still in a bit of an experimental place, and I'm sure things will
move towards a happy balance.

Re: [Elecraft] Strong recommendation: MFJ 18xx-series single-band whips for KX3, etc.

[GRANT YOUNGMAN]

I think some people mount them under one of the thumb screws — but it seems to 
me a lot simpler to just use a large enough alligator (or blunt nosed) style 
clip on the end of the radial wire.  Clip it right to the metal shell of the 
male BNC.

Probably a dumb question, but any suggestions on how to connect
counterpoise wires using the MFJ-1820T?  The loaded whip terminates in a
male BNC, which I assume is intended to connect directly to the KX3 antenna
