Re: [Elecraft] Elecraft business practices - more info

[Cliff Frescura]

Being in the payments industry, I can tell you that most of these policies
are driven by the card brands (Visa, MasterCard, etc.), certifying bodies
(PCI, EMVCo) as well as the payment gateways.  It is a very complicated
chain with many rules.

The shopping cart either does an immediate charge or what is called a
"pre-auth" where it holds the funds but does not transfer them yet.  If and
when they decide to actually charge the card, then a complete/post-auth is
issued.  The catch is that if a pre-auth is issued it will reverse
automatically if no complete/post-auth is issued, usually within 24 hours.
So the only practical choice is to charge the card.

The alternative is for the shopping cart to get a card token from the
gateway that it can store and retrieve for later payment.  It is verboten to
store clear text card numbers, in any media: computer, post it note, etc.
When the order is shipped, operations tells the shopping cart software to go
ahead and charge against the card token.  In this scenario it would be best
practice to the shopping cart software to also delete the token and
associated card data from the payment gateway, unless the cardholder
explicitly opted in to save card info.

This is not an Elecraft only issue.  Payments are very complicated and
challenging for many merchants.  Fundamental reasons are for risk reduction
(for all stakeholders) and security.

Subject: [Elecraft] Elecraft business practices - more info

I heard from Elecraft Sales and will attempt to communicate what I was told.

Sales is using a new shopping cart platform which allows them limited time
to capture payment information. As a result, it seems that they are unable
to defer payment in the case of a backorder, so orders are charged
immediately (as was the case for the two orders I placed recently). 

They said that they are testing a new application which will allow deferring
payment until actual ship time. The target for this application to be
implemented is next month. In the mean time they said they will add a refund
offer to the notifications they send to customers when a backorder occurs.

I am generally satisfied with this explanation but would have liked to have
told in advance.

Again, I have been a loyal and satisfied Elecraft customer for many years
and am not attempting to in any way talk anyone out of doing business with
them. I was surprised when my credit card was charged twice before shipment
was projected to occur and now I have more knowledge.

Thanks,
Lou

Re: [Elecraft] KPA1500 vs SPE Amps

[john]

Of course two KPA500's plus the Acom 3X2000A would be about much more
expensive and more hassle than just buying a single KPA1500.

Re: [Elecraft] Anyone use Solar Power for your ham shack?

I've employed a small solar power system to supply my ham shack which
includes K3-100/P3, two PCs with flat screen monitors, and 20" flat screen
TV.  This began as a basic test bed to understand Solar Power, so i know i
have lots to learn, and perhaps I have answers to help others with the same
interests.


I have been using a solar system with my station for 5+ years. I 
use a charge controller from CirKits 
 for my lead-acid AGM batteries. I 
have about 135 AH of battery and about 10-15 A of "12V" panels. 
(Note that the capacity of lead-acid batteries is much less than 
what is advertised. Ditto for the current from solar panels. The 
LiFeSO4 batteries seem to deliver closer to their specification.)


I power the K3, P3, antenna switch and various other things from 
the solar system. My laptop and the SVGA screen for the P3 run 
off mains power. I am in the process of setting up a 10" 
HDMI/VGA monitor that will run on 12V at 700-800 mA from 
Adafruit as a second monitor for my computer. It may also work 
as a SVGA monitor for the P3, but hasn't been tried yet.


If the batteries are fully charged I can operate a weekend SSB 
contest, assuming normal sleep and contact with the family. 
Operating QRP will go for a long time.


The charge controller can handle up to 20A of charge current, 
with modifications for 40A and 60A. The fact that the 
modifications include changes to minimize RFI gives me a warm fuzzy.


I also use a boost regulator to give my K3 about 13.5 volts. 
Mine is a TGE N8XJK Boost Regulator, which mostly works. It is a 
"20A" unit and tends to overheat and pop its 30A breaker when 
running with low battery voltage in high demand modes like FT8. 
Also, all the chip numbers have been scratched off and there is 
no circuit schematic. I would look for a different boost 
regulator if I were buying again.


A big deal everywhere is voltage drop. If you have 0.01 ohms 
between the charge controller and the batteries, and they are 
charging at 10A, them you will get a 0.1 volt drop in that line. 
If the charge controller is sensing battery voltage at its end 
of that circuit it will be off by 0.1V. Since the float voltage 
for my AGM batteries is between 13.4 and 13.6 volts, small 
values of resistance can lengthen charge times. (The charge 
controller thinks the battery voltage is higher than it really 
is, and cuts charge current. With less voltage drop, it raises 
the charge current. etc. etc.)


I'm thinking of trying a modification to the CirKits charge 
controller to use a separate wire between the battery and the 
voltage sense circuit, but haven't gotten around to it yet.

Re: [Elecraft] Anyone use Solar Power for your ham shack?

A US company called Genasun makes several models of MPPT charge 
controllers that are RF quiet. I use two in my shack, and W6GJB has two 
in his contesting trailer that we use for CQP, 7QP, and Field Day.  They 
make different models for lead-acid, lithium, and lithium-ferrous

Re: [Elecraft] Biz practices

[Gary Smith]

Just my 2 pence though nobody asked for 
it, Elecraft is one of very few companies 
that define the word integrity, another 
such company is HI-Z antennas who also 
goes overboard to be helpful in whatsoever 
is needed. I know there are other 
deserving companies out there, but these 
two are to me in the ham world, at the 
pinnacle of integrity and respecting the 
customer's needs and point of view.

All electronic pieces of equipment are 
subject to breakdown, especially those 
dealing with RF. Elecraft gets the repair 
work done correctly, as fast as is 
possible and they are more than reasonable 
in their billing. Add that their tech help 
is stellar and you have a quality 
operation. 

With quality and service such as this, 
I'll be happily using their products till 
the end of my days.

I'm just sayin'

[Elecraft] Dual KPA500

[Andy Durbin]

"Actually, I suppose one could drive 2 KPA500's from one K3 and sum the output 
for a virtual KPA1000."

If you dig a little into the design of the KPA500 you will find it has 
provisions to support 2 PA modules.  I have no doubt that Elecraft experimented 
with a dual  PA configuration before changing to designing the KPA1500.

Anyone willing to share some details?
