Re: [Elecraft] Alternative AMP to KX3 since Elecraft has temporarily stopped making AMPS

[Eric Swartz]

Hi Jim,

Your order came in while we we've under the shelter in place order for
Santa Cruz County, which slowed down production on the amps. We never
totally stopped their manufacture, but the rate of production was reduced.
 We're catching up now with the backlog and are certainly still shipping
all of the amps (KXPA100, KPA500 and KPA1500).

I'll check tomorrow and get back to you with what we think the remaining
time will be for your order to ship.

73,
Eric

[Elecraft] Alternative AMP to KX3 since Elecraft has temporarily stopped making AMPS

[HamRadioJim]

I have a KX3 and looking for an AMP (besides the elecraft brand) that is 100
watts or more that will work flawlessly with it.

I ordered the 100 amp from elecraft, but have been waiting over two months
for it, but they are out of stock and will be for some time. 

Has anyone purchased something else and has used it for a while with really
good results?  If you have not tested or used an alternative AMP for the
KX3, please don't respond to the post.  Just looking for those who have
actual results instead of suggestions.  Greatly appreciated.  Thank you.

Class D and E are home stations. They certainly began setting up long

Re: [Elecraft] WSJT-X and Split operation with transverters

[Nr4c]

To put a K3(S) into Split mode for DATA, both VFOs must be in same Mode/Submode 
before initiating Split. Easy way is to tap A=B twice quickly to copy frequency

Make sure VFO A and VFO B are on the same band and mode.  An A>B button 
tap will accomplish that.

[Elecraft] WSJT-X and Split operation with transverters

[Conrad PA5Y]

Hi all. I use the WSJT-X split mode with my K3S on 6m to ensure that if I wish 
to TX with a low audio tone I will not have audio harmonics in the passband of 
the TX filter. This works very well. However when I tried it on 2m with my K3S

It is a very useful feature when it is busy as I can often find a gap low down 
or very high.

Any help appreciated.

75 amp AGM batteries still $140.00 on epay w/free shipping, I prefer them to 
the 105 amp/hr batteries as they weigh a little less.
Use it w/50 watt Solar Panel and have done FD from start to finish with it as 
long as weather cooperates.

Thank you all, individually and collectively. Lots of great information,
not only about purchasing but also about operating the KX2 to get the most
functionality out of it. I've taken the comments and recommendations and
created a reference document for myself.

That was a decent price "a couple of years ago".  It's gone up since
then.  It's almost time to renew my Trojan 27AGM (75 AH) batts.  We're
planning to move a year from now and I hope that the existing ones will

[Elecraft] Questions about KX2 possible purchase

[Frederick Dwight]

I have been operating QRP portable for about 65 years.  Until about 15 years 
ago when I got my KX1, I mostly used linked dipoles, and other hard to erect 
antennas.  
Often I did not even set up for portable operation in a campground, mountain 
top, or just because it was too much effort.  All that changed with my KX1 with 
a
built in ATU.  A typical antenna for casual portable operation is a simple 26 
foot piece of wire and a 17 foot counterpoise wire laying on the ground.  This 
worked
great for 40, 30, and 20 meters, got me on the air in a few minutes, and 
produced many hundreds of QSO’s from my locations in Europe, the UK, and from
various places around the “lower 48” states.  Now for sure this simple antenna 
was not equivalent to more complex antennas which I sometimes erect for field
day, etc.  So I would get the ATU for sure, since compromise, or very 
compromise antennas are often your only possibility.  There are other “magic” 
lengths
of wire which enable operation on many other bands with an ATU.  I now have and 
enjoy a KX2 with more power and a better ATU.  I bought the AX1 since
money was not a concern, however I suspect that many (most) wire antennas will 
outperform it, especially on 30 and 40 meters.  You need to consider which
modes of operation, the power level, then number of hours of operation in a 
portable expedition, etc. before deciding the battery configuration.  One 
possibility
is one internal pack, then an appropriate external battery pack with enough 
capacity for an activation.  So far I really enjoy my KX2 with the paddle on CW 
and
have even tested it on SSB a few times.  No significant experience yet with the 
AX1.  Rick  KL7CW

Take a look at cqrlog, cqrlog.com  and see if that would 
work for you.

Re: [Elecraft] Field Day

[Bill Frantz]

Back around 1960, when IBM was developing the 360 series, the 
people working on the architecture document adopted a policy of 
not answering questions. Instead they rewrote the appropriate 
section and asked if it now answered the question. The result 
was the best architectural description of a computer ever produced.


I basically agree with Jim about emergency planning. For me, FT 
modes are out (even if they could pass the necessary traffic) 
because they require accurate time. My MacBook Pro doesn't keep 
accurate time without a continuous connection to a NTP source. 
When I'm at home, that comes via Comcast, which requires mains 
power, and will probably fail for other reasons as well. In the 
field I use my cell phone, which has the same problems.


Power is also difficult. At field day, I've used an inverter 12V 
to 120V to power my laptop power adapter. I don't have to 
describe why this solution is bad in so many dimensions to this group.


To solve the laptop power problem, I built a computer using a 
single board computer and a 12V monitor from Adafruit. When 
running it draws 800 mA, but the computer really isn't fast 
enough for the FT modes. Faster single board computers are 
available, but they draw more power.


This computer still doesn't solve all the problems, I haven't 
found a good linux logging program, and it would be nice to have 
a short term internal battery backup to save the computer state 
when it gets accidentally unplugged. The backup battery should 
be relatively easy. One solution just powers the single board 
computer and not the monitor. Then the user knows power has dropped.


Does anyone know of good logging software for linux?

[Elecraft] Field Day

[Andy Durbin]

The field day rules need to be reviewed and corrected, not just for allowed 
power sources.

Take this for example -

"3. Date and Time Period: Field Day 2020 will be held June 27-28. Field Day is 
ALWAYS the fourth full weekend, beginning at 1800 UTC Saturday and ending at 
2059 UTC Sunday.
 3.1. Class A and B (see below) stations that do not begin setting up until 
1800 UTC on Saturday may operate the entire 27-hour Field Day period.
 3.2. Stations who begin setting up before 1800 UTC Saturday may work only 24 
consecutive hours, commencing when on-the-air operations begin.
 3.3. No class A or B station may begin its set-up earlier than  UTC on the 
Friday (Thursday afternoon or evening local time) preceding the Field Day 
period. Cumulative set-up time shall not exceed a total of 24 hours."

This rule set allows a 1E station to operate for almost 27 hours.  The contest 
start and end times are defined in rule 3.0.  None of the subordinate rules say 
that a 1E station that performs all setting up after 1800 UTC Saturday is not 
allowed to operate for the full contest period.

It takes me less than 1 hour to convert from mains power to running the entire 
station on a generator.  The rules, as published, allow me to connect and start 
the generator after 1800 UTC Saturday and continue operating until 2059 UTC 
Sunday.

ARRL representatives have told me that 1E stations may operate only 24 hours 
but the rules don't say that.

Andy, k3wyc

Re: [Elecraft] Field Day

[Jim Brown]

Bill,

I understand the intent of the statement in the FAQ. My point is that 
these clarifications should be part of the FD RULES, not an FAQ. To me, 
an FAQ is answering questions raised because the Rules are poorly 
written or incomplete. If I were running things, I would ban all FAQs 
and tell the author(s) of the basic document(s) to finish their job!


When I first did FD in 1957, we logged on paper and kept paper dupe 
sheets. One guy operated, a second kept the log and the dupe sheet. The 
rules have not changed much since then, and to some extent, those days 
are still the mindset of both the League and many club participants.


BTW -- my question about the monitor was rhetorical, and I don't agree 
with your logic about it. It's part of the computer's user interface -- 
we humans can't operate the computer to control a radio without it.


The good thing about requiring true backup power for the computer causes 
us as hams to think more seriously about running in emergencies. The bad 
thing is that independent of the mains AND not powered by a generator is 
that most laptops now need 16-20V at their power socket, it's hard to 
find QUIET DC-DC converters, and it probably takes more power to run the 
laptop than to run a KX3.


There's the interpretation of another contesting rule that is the basis 
of "split site" operation during Sweepstakes. Two operators run one day 
from their own QTH, then trade QTHs for the second day. This was 
originated by our own big club, NCCC, and has since been adopted by 
other clubs. The RULES says that 1) each operation needs to use a 
different call (usually a Club call) and 2) a TRANSMITTER may be used 
with only one call during a contest. This means four calls and four 
transmitters. Starting out in broadcasting a few years after that first 
FD, I've always viewed a power amp as part a transmitter, but the Rules 
are not interpreted that way -- they apply it only to the transceiver!

The monitor does not control anything, so it can be powered anyway you want.  
But if you push buttons on the Winkeyer and it’s not connected to the computer 
then you are ok. But if you let n1mm do the keying ( Winkeyer or not) then the 
computer must be on battrry or some form of emergency power.
