Re: [Elecraft] OT: Some "No Code" background

2016-08-01 Thread Kevin - K4VD

Wait a moment. I do not subscribe to the notion that today's hams are any
less capable than hams of the old days. I think that is old-timer thinking
bordering on the curmudgeonly. "Kids these days."

Today's hams know different things. Things some OT's may not understand,
value or appreciate but still valuable and worth knowing. New techniques,
modes, devices and interests, are a constant I can't keep up with.

New hams are a force to be reckoned with. I'll do my best to keep up with
them and enjoy the fruits of their ingenuity.

Re: [Elecraft] OT: Some "No Code" background

I agree with this paragraph, Joe, however, I strongly disagree that a 
knowledge of CW at any speed is a reasonable or even a relevant standard 
for entry in the 21st Century. There is no evidence that a knowledge of 
CW makes a license holder better equipped to advance the state of the 
art either. Certainly the quality of some operators and their behavior 
is abhorrent, but it is more a reflection of the general population than 
it is lack of code proficiency. Furthermore, proof before an examiner of 
code proficiency doesn't say anything at all about a trained pool of 
operators, esp. in an age when nobody but hobbyists use code anymore. 
What are they training for?


The only reason for an FCC amateur license is to show you understand and 
will abide by the rules for emitting RF in the amateur radio spectrum. 
Evidence for that assertion is that the state of the art in computers 
and software is advanced by people including kids who don't have any 
license whatsoever. Same goes for astronomy or motorcycle racing or 
bicycle design. You name a hobby and most in it are not licensed by 
anyone to do it. They just do it.


So a higher standard for entry would involve a proof of understanding of 
Part 97, e.g. to show that the prospective licensee knows what emissions 
violations look like and has some clue as to how to resolve them. 
Testing them on the difference between a Colpitts and Harley oscillator 
is and probably always has been pointless.


BTW, I'm about 95% CW for going on 60 years. I haven't been on any voice 
mode for at least 10 years, but I do operate some JT9/JT65.  I got my 
first microphone 24 years after I was first license. I took exams for 
General, Advanced and Extra before FCC examiners on both coasts who all 
looked like Lou Grant.


A personal observation? Most of the ragchews I have on CW these days are 
with no code hams, many of them SKCC members. If a ham likes antennas, 
satellites, emcomm, CW or whatever, they will gravitate towards it when 
they get the license. The standard of entry is the ability to do it 
legally and ethically.

You do. My alter ego is a wannabe author. Unfortunately time is a zero-sum game

Yeah but ... (;-)

Your arguments are correct

Even at the time of the no code committee meetings it was glaringly
apparent that it was ... essentially ... a case of raw numbers.
Politically we needed ... and now even more so ... need our "body count" in
the face of the economic and political challenges to our
frequencies.  The FCC told us this in no uncertain terms.

You should have seen what they initially proposed in their version before
we tweaked it!

Re: [Elecraft] OT: Some "No Code" background

2016-08-01 Thread Joe Subich, W4TV



Given that amateur radio in the US is now completely "no code" - there
is no need to become proficient even for an Amateur Extra class license
- the early "no code" steps were a Faustian bargain just as the fiction
of "semi-automatic control" for digital operations was a Faustian
bargain.

As much as it pains me to say, we would arguably be better off with
fewer licensees and maintaining a reasonable standard for entry.  There
is no credible evidence that amateurs can continue to advance the state
of the art and evidence to the contrary that the current license base
represents a trained pool of operators.  The quality of operators and
the behavior heard on the air today is abhorrent when judged by the
standards of 15 years ago.

Perhaps it is time to review the basis and purpose behind amateur radio
and move to a "national park" model.  That is a place for those who
have proven that they have the necessary skills to continue to practice
those "ancient" and no longer commercially viable skills.  Consider it
the "primitive" areas of the National Parks

Re: [Elecraft] EC2 Clone (Was The 1500 watt amp)

2016-08-01 Thread Wes Stewart


Nice work!

I too have built my own enclosures with similar techniques.  A couple of my 
projects can be seen here: http://sadxa.org/n7ws.html#amp


Although at the time I had access to a prototype workshop, I have done similar 
work at home with comparable results.  If possible, I avoid bends.  In all of 
this stuff I used 0.062" 6061-T6 material so it wasn't going to bend anyway.  
The harder alloy drills like a dream. For all of the corner joinery I used 3/8" 
square stock, 8/32 threads and stainless steel screws


In the protoshop, I had access to a shear but all of the sheared edges were 
still smoothed by hand.  I had a granite surface plate and used a vernier height 
gauge for layout so similar parts were interchangeable.  In the home shop I lay 
out as carefully as possible and match drill on a drill press. Most people can't 
tell the difference.  With a lot of elbow grease a hacksaw works, although after 
a lot of furniture building and finish sanding, I needed rotator cuff surgery so 
I don't do that anymore.  With extreme care and I do mean extreme, a carbide 
toothed blade on a table saw will cut aluminum if it's thick enough and the 
blade has fine enough teeth.  Otherwise I use a bandsaw, which is always safer, 
if less precise.


In the protoshop I had access to chemical dip baths for passivating the 
aluminum, silver plating the RF parts and a panograph engraver for panel 
lettering.  Silver looks nice, but is highly overrated as an RF conductor.*  In 
the home shop, before the un-elected bureaucrats in DC decided we were too 
stupid to handle lye (judging by the electorate they may be right), I would etch 
aluminum in a lye bath, rinse and neutralize with vinegar and a final water 
rinse.  This would yield a nice satin finish.  The best I have found since is 
oven cleaner.


Another finish, if you like the look, can be had by using a random-orbit sander  
Play with the grit until you find something you like.  Sanding it wet with a 
little cutting oil can be fun, albeit messy, too.


Tube amplifier still have their virtues and, along with antennas, can be great 
roll-your-own projects that can work better than what you can buy.

If you can build whatever you want, you can easily build the enclosure. Here 
is an EC2 clone I built last week in about 6 hours. I made the side panels 
with a hacksaw, file and drill press. The front panel I cut and formed with an 
inexpensive 8" shear/brake. This one is branded Grizzly, but Harbor Freight 
has them as well. I didn't use the Elecraft 2D fasteners because I only had 2 
on hand and didn't want to make a bunch of little fussy pieces. I used 4 long 
sections of 1/4" square aluminum stock and drilled them with the same hole 
pattern as the 2D fasteners. The front panel will get painted after I drill 
and punch it for the current project.


https://flic.kr/p/KBivtc

The smaller K1 enclosure is nearly the same design (slightly different top 
cover) so it scales down easily. It would scale up for a large amp just as 
easily. The cost of the EC2-clone was about $4 in materials (0.080" and 0.050" 
sheet and 1/4" bar stock). All can be built with a hacksaw, file and a hand 
drill. A bandsaw and a drill press make it more precise. A shear/brake makes 
it even easier.

Re: [Elecraft] OT: Some "No Code" background

2016-08-01 Thread Daniel B. Curtis

Ken
I have learning disabilities.
It would have been impossible for me to get an Amateur Radio license
without your efforts.

I have spent been 5 years trying to learn code and am now am almost
competent at receiving 12wpm (I am trying to learn it because it is hard
for me and hits all my weaknesses --- a masochist.).

I would never have tried to learn code unless I had an Amateur Radio license
first.

Thanks and 73

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?

2016-08-01 Thread James Bennett

Huh? How does my situation even closely border on producing “ill effects”? 
This is NOT the situation here, so let’s set the record straight. 

1) My stealthy wire doublet is 45 feet in the air. I experience ZERO RFI 
problems even at the 500 watt level. Nor do my neighbors, who I’ve asked 
several times if there are issues.

2) I would be interested to see what sort of person or animal is going to come 
into contact with an antenna at that height. Actually, maybe I don’t want to 
see - might be pretty scary sight.

3) Don’t know where my post mentioned whips or short wires. None here at this 
station.

4) True, but again, not here.

My post simply was intended to convey my desire and reason why I do NOT want to 
run any more power than I already do, and any correlation of my installation to 
someone with a dipole five feet off the ground or experiencing RFI is off the 
mark. And not fully appreciated.

That would be a no for me. Money is not the issue. Just do not need more 
than the KPA500 I now have. Only use it now for skeds when conditions do 
not support a contact at 100 watts.

Re: [Elecraft] [KX3] Computer interface for KX2?

2016-08-01 Thread Mark via Elecraft

I suggest an SD-AUD20101.  It has stereo input and output (2 DAC's for output 
and 2 ADC's for input) so it can utilize the KX3 IQ output. 

https://www.amazon.com/gp/aw/d/B006SF68P2/ref=mp_s_a_1_1?ie=UTF8qid=1470087537sr=8-1pi=SL75_QL70keywords=sd-aud20101


There are others out there, but if you want to use it in a pan adapter setup, 
having 2 input ADC's is critical.

2016-08-01 Thread Kevin - K4VD

Hi Ken:

As a CW operator, I think you did well in helping to secure the future of
Amateur Radio (proud to be a ham). Years later it seems apparent to me the
impact has been generally positive.

Your last comment... "Please, let's not start a thread on the subject.  I
just thought some "first person" input would be of interest."

Seems like an odd statement to make to a discussion group. I assume you are
trying to avoid a code/no-code argument.

paddle is as new in appearance and mint in its 
operating condition. It will include the limited 
accessories that accompanied it (cleaning cloth, 
spacer and cable)and it will be shipped in the 
original box.


Sell for $229 shipped UPS Ground in the 
Continental US.

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?

2016-08-01 Thread Ron D'Eau Claire

A serious mistake some antenna-limited Hams make is to try to make up for a 
poor antenna near the ground with more power. A situation like Jim brings up 
would likely produce a number of ill effects such as:

1) Producing interference in many nearby pieces of equipment from Hi-Fi systems 
to DVRs, broadcast receivers, etc.

2) If the antenna is not carefully insulated and isolated, animals and people 
can receive very painful RF burns and in the extreme set fires. For those who 
have not experienced a severe RF burn, it instantly creates deep tissue damage 
that is very painful for days or weeks afterward.

3) Short antennas (whips, short wires, etc.) easily produce corona discharges 
at their ends that distorts the transmitted signal and creates broadband Hash 
across the ham bands. 

4) It becomes very difficult to ensure people are not subjected to excessive RF 
exposure if the antenna is not up high and in the clear.

Wayne, if it turns out to be a survey, put me down for a NO vote. I run my

surprised they don’t vaporize as it is with the 500 watts or so coming out of 
my KPA500 - on the rare occasions when I do run QRO!

[Elecraft] OT: Some "No Code" background

2016-08-01 Thread Ken G Kopp

I got one of the 1st Novice licenses issued ... in September, 1951.  Took
the exam in Oklahoma City, where the FCC came only once per year.  My
"Elmer" was a retired Navy CW op and I was taught well.  Long ago I was a
commercial shipboard RO on a NOAA vessel.

I'm one of the six people who created the "no code" license.  In what I
consider one of the greatest honors in my Amateur Radio ... I -detest- the
name "ham" ... career the ARRL appointed me as one of the six members of
their No Code Study Committee.  BTW, each of us were / are die-hard CW
operators.

We we --told-- by the FCC that we would be getting some form of codeless
licensing and we should come up with something that most could live with.
Lots of "details" were covered over a year and a half of meetings,
conference calls, etc.

I still have a large box of pro and con correspondence in the attic.  The
number of letters is about equally divided.

An example of the results ... yesterday I had a KE0 proudly tell me he'd
just passed his "expert" license, and, his radio emitted a multi-tone CB
"roger beep" each time he unkeyed his microphone.

Without the "no code" license we most likely wouldn't have Amateur Radio
with the record 750K licenses we have today, and there's political "safety
in numbers".

Please, let's not start a thread on the subject.  I just thought some
"first person" input would be of interest.

Re: [Elecraft] [KX3] Computer interface for KX2?

2016-08-01 Thread Don Wilhelm

Data modes require only mono - only the left channel is used.  The 
SignaLink interface is mono.

Of course, the KX2/KX3 requires a stereo plug.

An exotic soundcard is not required for data modes, although ones with a 
low noise floor will decode weaker signals.


If you are thinking of a panadapter application from the KX3 I/Q 
outputs, then you need not only stereo, but a good soundcard.

Re: [Elecraft] Zombie Amplifier? (was Re: KPA-1500 needed)

Zombies don't need amps -- they have a different form of waves, and a
different form of propagation. But it only works when the whole path is in
darkness.

Re: [Elecraft] [KX3] Computer interface for KX2?

2016-08-01 Thread Jim Rhodes

The question I had when looking at this type of sound card is "will it do
stereo line input?" I did find one that did and it was in the $10-15 range.
Many of them only do mono at Mic level. Use mine with the KX3 most of the
time, have used it with K3.

Re: [Elecraft] The 1500 watt amp

2016-08-01 Thread Jerry More

We just differ in opinion and I’m happy for everyone to enjoy the hobby as they 
are able. The issues I see is where the Amateur code is broken. Just listen on 
DX pileups sometime and you’ll hear guys that really make us look bad as a 
community. 

About the only time I can imagine someone needing power is perhaps a DX station 
but that’s IF they can actually hear. 
Doing the math I am probably missing something because I don’t see much of a 
gain from 500w to 1.5kw into the same antenna system.
From memory 500w to 1k is 3db and 1k to 1.5kw is 1.5 db, so 500w to 1.5kw is 
4.5db
6db is 1 S unit (from memory) so running a 1.5kw amp gives just less than 1 S 
unit. 

Now start factoring up the DB gain/loss for antennas/feedline.

Which gives the best bang for the buck?? 

Maybe I’m just slow. Seems to me a nice, instant on 500w solid state with 
quality low loss feed line into a matched antenna should rock and roll. 

This thread should probably die. 

Enjoy the hobby as you wish. Just know any station who worked em with less 
power just owned you regardless of your budget 

Jer & Fred,

You're right from a certain point of view.  But also consider more 
generally that it's about link budget; maximize gains, minimize losses. 
How much of each a ham can do comes down to money & motivation within 
lifestyle (& FCC!) constraints.

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?

Nice work, Ken. On the amps and the cars. I was wondering the same thing 
about "rolling your own". I suggested that doctor who said he could 
build pretty much what he wanted could build the enclosure. He owns an 
electronic lab which builds his stuff and farms the enclosures out to 
another professional. Not sure subcontracting is the Ham Spirit, but 
we're all in this hobby for different reasons.

 My whole Ham life I've been told to put the money into antennas, better
 feedlines, and a better receiver.
 If you are a skilled operator then you'll make the contact if band
 conditions permit.
 Doing the math I really don't see why anyone "needs" an amp past
 500-600watts. Maybe on 60/160?
 If a QRP /Low power station can make the contact but you can't then
 maybe
 you need to ask for help getting your station optimized a bit better.
 Just my view.
 I used to run an SB220 and loved it when I made the contact. I later
 came to
 resent Ops I heard running power just to get over the pileup.
 I sold the Amp and don't regret it for a minute. If I were to get
 another
 amp the math shows 500w to be the sweet spot, however, I have so much
 opportunity to improve feedlines and antenna it doesn't makes sense to
 run
 power at this time.

 Just my view.
 Jer

Re: [Elecraft] The 1500 watt amp

2016-08-01 Thread Graham Kimbell

Watching this from afar, I notice the irony - US has 1500W limit but not 
enough (120v) mains power to use it, whilst the UK has loads of mains 
power (240v at 13A) but only a 400W limit.


Graham



The KPA500 can be run from any decent 120VAC mains outlet as long as there 
aren't too many other loads on it. But going above that power level forces the 
Ham to have 240 VAC in the shack, something many of us do not normally plan 
for. That can be a very expensive addition to the cost of the amp, especially 
if the mains panel is not expandable as needed.

Doing the math I really don't see why anyone "needs" an amp past
500-600watts. Maybe on 60/160?
If a QRP /Low power station can make the contact but you can't then maybe
you need to ask for help getting your station optimized a bit better.
Just my view.
I used to run an SB220 and loved it when I made the contact. I later came to
resent Ops I heard running power just to get over the pileup.
I sold the Amp and don't regret it for a minute. If I were to get another
amp the math shows 500w to be the sweet spot, however, I have so much
opportunity to improve feedlines and antenna it doesn't makes sense to run
power at this time.

Just my view.

[Elecraft] KXPA100 utility - power on/off

2016-08-01 Thread Dan M - yo3irm

Hello,

is there any possibility to power-on/off KXPA100 using the utility program ?
I have a remote location where KXPA 100 will be installed and the only
option I can see is to leave the power button ON and just switch the power
supply on/off via a remote controlled outlet.

Thank you !

73, Dan

Guess what!  2018 promises a mid-engine Corvette.  Management is entitled to
change its mind.  If all the feedback is "I don't see the needI can buy
the same thing elsewhere...500 watts is enough...blah blah blah", then
management doesn't hear from your so-called "huddled masses" who ARE saying,
"Yeah, I wish they would do that..."   You don't need to answer for Wayne

Re: [Elecraft] [ELECRAFT] K2 don't communicate with KPA100/KAT100(in same EC2)

2016-08-01 Thread Don Wilhelm

Bo,

Since the base K2 works properly with the KAT2, I doubt you have a
problem with Control Board U6. Make sure you do have power control with
the base K2 and KAT2 in place - set the power for 5 watts and connect an
external wattmeter to see what the actual power may be - you should
measure close to 5 watts.

Check the KIO2. The inductor L1 on the AUX2 board and inductors L2, L3
and L4 on the KIO2 board should show continuity - if not replace them.

Your pin misalignment would have placed 12 volts onto the VRFDET line to
the KPA100 - if your luck runs good the KIO2 inductors may have acted as
a fuse, but it is possible that KPA100 U6 could have been damaged.

It may be informative to remove the QRP top cover and connect the KPA100
(removed from the EC2 enclosure) directly to the base K2 to check its
operation and ability to control power in the above 11 watt range. If
you do not have good power control with the KPA100 connected directly to
the base K2, replace KPA100 U6 and check again.

73,
Don W3FPR

After that I made the frequency calibration of K2 I made a mistake when I put contact from KIO2 and KAT2 to Control board. I put the Contact one unit up, pin 3 from KIO2/KAT2 come on pin1 on P4.

When I put all together and test, KPA100/KAT100 (both in same EC2) don’t respond.

Using Ant ½ I got answer ”PA ANT 1” also when I use menuitem ”ATU” I got the same answer ”PA ANT 1”

I hear a relay click in KPA100 when I switch on the radio.

Testing single K2/KIO2/KAT2 all work well.

Testing K2/KPA100 got 20 W with 1 – 10 W on powerbutton and full power on over 10 W.

Can’t change power with the powerbutton.

Perhaps U6 on Control Board is out of order! I measure all pin and got som differens against value in the manual.

Re: [Elecraft] Higher Power than KPA500

2016-08-01 Thread w7aqk


Greetings all,

This ongoing urging of Elecraft to build a 1.5 KW amp is, at times, sort of 
interesting, but often it is a bit tiresome, if not non-productive.  Most of 
us have no clue as to the problems involved in producing something like 
that.  I don't think there is much doubt that Elecraft has the ability to 
create something like that, but is it worth it?  I suspect there is little 
appreciation out there for the headaches (and risks?) that go with it.


Many of the pros and cons of a bigger amp have been mentioned, but I am sure 
there are a lot more.  Also, although many express certainty about the 
existence of a "market" for a larger amp, I am not convinced that a handful, 
or even several handfuls, of those comments here are all that substantive or 
convincing.  They certainly do not represent a well constructed "market 
survey".  More importantly, they probably ignore the dozens of problems 
associated with such a project.  Besides, if it doesn't fit their business 
plan right now, then that's their call!


Elecraft did have a prototype high power amplifier several years ago--I saw 
it!  What that tells me is that Elecraft has already looked into this, at 
least to some extent.  Thus, I think we should give them credit for what 
they already know about such a project, and just let them come back to that, 
if they ever do, at their own pace.  Elecraft is a well run company, but not 
a particularly large one.  I suspect they are averse to taking big risks, so 
we should respect that.  It is much to our advantage that Elecraft keeps 
putting out "winners".  Putting out "losers" will probably only divert their 
attention, which is to our detriment.


I strongly suspect that the earlier "look see" at a high power amplifier may 
have been Eric's idea.  I also strongly suspect he may have been the one 
that "killed" the idea.  Not that Wayne isn't good at this sort of thing, 
but I think Eric is particularly good at it, and that this is a big part of 
his job description.


Anyway, suggestions from us are probably often helpful additions to their 
idea pool, but I doubt that "badgering" them is very helpful at all.  Look 
at how many times they have had to squelch the comments!

[Elecraft] [ELECRAFT] K2 don't communicate with KPA100/KAT100(in same EC2)

2016-08-01 Thread Bo Andersson

My K2 and KPA100/KAT100 have served me for over 10 years now without any 
problem!
 
After that I made the frequency calibration of K2 I made a mistake when I put 
contact from KIO2 and KAT2 to Control board. I put the Contact one unit up, pin 
3 from KIO2/KAT2 come on pin1 on P4. 
 
When I put all together and test, KPA100/KAT100 (both in same EC2) don’t 
respond. 
 
Using Ant ½ I got answer ”PA ANT 1” also when I use menuitem ”ATU” I got the 
same answer ”PA ANT 1”
I hear a relay click in KPA100 when I switch on the radio.
 
Testing single K2/KIO2/KAT2 all work well.
 
Testing K2/KPA100 got 20 W with 1 – 10 W on powerbutton and full power on over 
10 W.
Can’t change power with the powerbutton.
 
Perhaps U6 on Control Board is out of order! I measure all pin and got som 
differens against value in the manual.
 
Pin My U6  U6
 
  6  0.0 4.7
10  0.0 5.0
13  0.7 2.3
18  5.0 0.0
25  5.0 0.0
33  0.08   5.0
36  4.6 0.8
39  1.02   0.2
 
Hope I manage to explain the problem!

[Elecraft] Zombie Amplifier? (was Re: KPA-1500 needed)

2016-08-01 Thread Fred Jensen

It's baaack?  I thought both Wayne and Eric dispatched this black lagoon 
creature a couple of years ago.  I know a prototype [or mock-up?] was 
shown at Dayton earlier, but when W both disclaim it later, I tend to 
believe them.  The list has been full of late with subjects that don't 
interest me and I exercise the Del key rapidly, did I miss news of its 
reincarnation?

I don't buy this logic. I've optimized my station and have an antenna 
farm most hams would die for. I've got 320 countries confirmed with 
unlimited power, running 1.5kW to work the ones over difficult paths. 
Since I'm not competitive in DX contests from W6, I often work them QRP. 
I have about 160 countries confirmed running 5W.


Others have said it quite well -- the primary reason for running high 
power is receive noise at the station you're trying to work. If the 
other guy's noise is S9, you're unlikely to work him QRP, no matter how 
much you have optimized your station. Likewise, if your antenna is a low 
dipole or a wire strung into a tree, you're starting with at least one 
hand tied behind you. No use tying the second hand with low power.

[Elecraft] EC2 Clone (Was The 1500 watt amp)

If you can build whatever you want, you can easily build the enclosure. 
Here is an EC2 clone I built last week in about 6 hours. I made the side 
panels with a hacksaw, file and drill press. The front panel I cut and 
formed with an inexpensive 8" shear/brake. This one is branded Grizzly, 
but Harbor Freight has them as well. I didn't use the Elecraft 2D 
fasteners because I only had 2 on hand and didn't want to make a bunch 
of little fussy pieces. I used 4 long sections of 1/4" square aluminum 
stock and drilled them with the same hole pattern as the 2D fasteners. 
The front panel will get painted after I drill and punch it for the 
current project.


https://flic.kr/p/KBivtc

The smaller K1 enclosure is nearly the same design (slightly different 
top cover) so it scales down easily. It would scale up for a large amp 
just as easily. The cost of the EC2-clone was about $4 in materials 
(0.080" and 0.050" sheet and 1/4" bar stock). All can be built with a 
hacksaw, file and a hand drill. A bandsaw and a drill press make it more 
precise. A shear/brake makes it even easier.

Re: [Elecraft] The 1500 watt amp

The point is dominance. If you are the strongest signal, the DX hears 
you better. If you are the strongest, you hear the DX better because 
everyone else stands by until you make the contact and go away. I lived 
among the legendary California Kilowatts when I was a DXer. Letting them 
in and letting them chat about their vacation at that location with the 
DX because they could was the only way you could work the DX eventually 
yourself. Same as in life.

I don't see the point of having a large power amp. It doesn't help receive.
My whole Ham life I've been told to put the money into antennas, better
feedlines, and a better receiver.
If you are a skilled operator then you'll make the contact if band
conditions permit.
Doing the math I really don't see why anyone "needs" an amp past
500-600watts. Maybe on 60/160?
If a QRP /Low power station can make the contact but you can't then maybe
you need to ask for help getting your station optimized a bit better.
Just my view.
I used to run an SB220 and loved it when I made the contact. I later came to
resent Ops I heard running power just to get over the pileup.
I sold the Amp and don't regret it for a minute. If I were to get another
amp the math shows 500w to be the sweet spot, however, I have so much
opportunity to improve feedlines and antenna it doesn't makes sense to run
power at this time.

Just my view.

Re: [Elecraft] The 1500 watt amp

2016-08-01 Thread N2TK, Tony

I remember seeing the KPA1500 at Dayton heating up the building. I reached
for my credit card but was told not taking orders. Bummer.

Today I have a KPA500 and an Acom-2000A (very early one) sitting on a shelf
7' off the floor in the basement. Literally right below my feet here in the
office/shack. Keeps the heat and noise downstairs. Both track the K3. So
when I key the amp it is on freq and ready. I have two switches between the
pair of K3's - one to select which K3 and one to select which amp.
Most of the time both amps are off. I find 100 W is usually enough. But in a
decent pileup I will turn on the KPA500. For DXpeditions like VK0 and FT4,
especially on the low bands, I can get in and out more quickly with the
Acom. For contesting the Acom stays on the entire weekend.

This setup also gives me backup in case one of the amps fail. Also give me
more watts on 6M.

Someone mentioned about you got to hear them to work them. And I agree money
should be first spent on receiving - equipment, antennas, coax, receive
antennas, etc. But once you have optimized as much as you can because of
land, money and other restrictions, an amp is a nice way of helping you in a
pileup to work a station you can hear. And especially on the low bands going
from 500 to 1500 W may make the difference from working and not working a
station.
I still remember the one morning I heard Zone 19 on Topband for my first and
only time at my sunrise. Unfortunately I did not have the KPA500 then. Only
had the Acom. But the Acom was off. While I waited for the Acom to heat up I
tried calling the UA0 with 100W. He knew I was calling him but he could not
pull out my full call. By the time the Acom cycled ON, the UA0 was down in
the noise. Bummer.  

73,
N2TK, Tony

I'm with Greg. Though I am only a casual DX chaser and even more casual
contester I found the KPA500 just wasn't enough to suit me, but I knew that
going in. I only ordered the 500 as a temporary measure to hold me until my
2K-FA came in. I certainly would have gone with a 1500w Elecraft product, if
it existed.

Re: [Elecraft] K3S Data Connections

2016-08-01 Thread Don Wilhelm


Jim,

When connecting the K3S to the computer via a USB cable, both the 
soundcard and the USB to serial adapter in the K3S should be recognized 
by the computer.
Just steer the data mode software application to use the soundcard and 
COM port that are assigned by the computer.


This is more of a computer situation than a K3S situation.  Which 
soundcard and which COM port is assigned is highly dependent on what the 
computer does.  If Windows, look in Device Manager to see the COM port 
and soundcard assignments.

Folks,

I have a mid-2010 vintage K3 and more recent KX3 that I use for JT65/9, WSPR, and 
FLDIGI, in addition to CW. For those digital modes I run external USB sound cards 
- Tascam US-125M. On the K3 the Tascam connects to the K3 line in and line out and 
to the computer via USB. That's where the audio signals are exchanged. The K3 
connects to the computer via a serial->USB device. With the digital modes, the 
rig control signals traverse this path. All well and good.

Now, a fellow Elecrafter with a K3S wants to do digital and has asked me what he needs. I 
know that rig has built in sound card, so I thought he wouldn't need the external unit 
like I have. But, not having a K3S, I'm confused how things work. The online manual (Data 
Mode Connections, pg. 33) says that "You can transmit and receive data in one of 
three ways". None of those three ways listed refer to that built in sound card.

I guess the bottom line question is: can one run a program like FLDIGI and/or 
WSJT-X on a K3S without the need for an external sound card, and still have 
those programs do full rig control like the K3 that I have? If yes, what 
connections are made between the radio and the computer...?

Re: [Elecraft] The 1500 watt amp

Buy some of the "2D " blocks from Elecraft and have Front Panel Express   to 
make the panels for you from your design.
