Phil,

My understanding of the Rules is that if a product is used in a 
residential neighborhood it must be certified to Class B. Am I mistaken?

Well what would be really useful before would be manuals, even preliminary ones

I'd like to have the mod for power thru the RJ45 connector done so upon arrival 
it would be plug and play.

Although we wish that it would be so, it is very doubtful if there are
any street lamps that are certified to meet FCC Part 15 standards as

Re: [Elecraft] [OT] Street Lamps and RFI

[Fred Jensen]

My experience with two [a small sample] of street lamps, both owned by 
the State of California [CALTRANS], is that the lamps don't really 
matter much, it's the controllers ... what we used to call ballasts but 
that's archaic now.


One appeared to be a fairly old high-pressure sodium vapor lamp, and it 
emitted a steady buzz centered on 6 Mhz and spread from about 3 Mhz to 8 
Mhz.  It was about 3 km away and ran about S5-S6 on my K3.  A similar 
lamp maybe 4 km distant emitted nothing.


The other was what I believe a low pressure lamp.  It's problem was that 
it was failing ... very, very slowly ... and the controller [or ballast, 
your choice] would emit sharp spikes in a spectrum that ran from 160 
through 17 m as it continually tried to restart the lamp.


After multiple contacts to my state government, I gave up and we finally 
moved [not because of that :-)].  The failing one has not yet died, saw 
it last time through Auburn ... it does this day and night.


You might want to point your Association to 47CFR15, and their 
responsibility to prevent interference to licensed services.  They might 
care about that, CALTRANS never did.

Re: [Elecraft] [OT] Street Lamps and RFI

Karl,

It might interest them to know if the street lamps (or any other 
devices) create RFI to licensed radio services (Amateur Radio included), 
they must turn those devices off and rectify the problem.
Of course, the FCC would be involved should that happen, but they must 
rectify the RFI problem in any case.


They may not understand why it matters to them until you make a 
complaint to the FCC and they are asked to shut the RFI generators down.


Caution, the enforcement process can take some time, so if you can steer 
them to RFI-free devices, that is the best solution.


I don't have any pointers to RFI-free street lighting.

Re: [Elecraft] Solar Charge Controllers (was Field Day)

[Jim Brown]

On Wed,6/8/2016 8:42 PM, Jack Brindle wrote:

Thee is an issue with the cheaper solar controllers - they tend to place the 
switching transistor in the ground leg, making connections difficult. For 
example the Sunforce controller that Jim mentions uses an N-channel FET as its 
pass transistor, in the ground lead. If you then connect the radio or other 
load to the battery while it is being charged, you can end up with a floating 
ground. One local solar expert discovered that his setup of this kind caused 
massive current flow on the shield connection of a USB cable - it was 
essentially carrying all the ground current!


Thanks for the alert, Jack. However -- the controller I referenced is a 
low power product, specifically designed for a single panel charging a 
battery. Such panels are rarely connected to a ground except via the 
return side of the pair feeding the battery through the charge regulator.


Also, if a USB cable is the only connection between equipment in a 
system, that system lacks proper bonding.


Abuse of the return conductor is not limited to devices like these. The 
very popular Watts Up inline volt-ammeter meters in the return lead, 
which can lead to very wrong answers when used to measure current within 
a station, for exactly the reasons Jack notes -- DC return current 
divides between the intentional path (the return wire) and all of the 
other return connections between equipment in a station, and bonding 
conductors.


The Hamsource EZmeter ($80) and the West Mountain Radio PWRcheck ($180), 
both sold by DX Engineering, measure current in the positive conductor. 
I found the EZmeter at Pacificon last fall and quickly added it to my 
collection of test gear.

evaluate OEM sources and their products with the resources of a good

Re: [Elecraft] K3 8khz wide sig tracks VFO A ~30khz lower in frequency

[Phil Wheeler]

Eric,

Re "Also, if you have an extra BNC-BNC cable, try 
replacing this cable.": Really!  Yesterday I was 
testing a newly received mag mount to make sure 
this (MFJ!) product was OK. Connected a dummy load 
to it via a BNC-BNC connector and VSWR was not 
flat and impedance varied significantly with 
frequency.  Changed dummy load: Same result.


As it turns out the problem was in the BNC-BNC 
cable, not the device I was testing. Verified by 
mounting one of the Elecraft dummy loads direct to 
the mag mount, then via a different cable which 
was OK.


BTW -- the BNC-BNC mag mount is for use with the 
MFJ 18XX-T whips, so I can mount them remote from 
my KX2/3 vs. always on the rig with rt angle BNC 
adapter.  Seems like a good option to have, since 
I have two of the whips (20 and 40)!

Images can be seen here:
https://picasaweb.google.com/k5oai.sam/6293813435183959297

No antenna was connected to the K3. The only cables connected to the
P3 were: Coax and RS232 from K3. I attached the RS232 to the computer
to get the snap shots, bet the signal did not change with it connected
to the computer or not.

Note: During the snapshots I bumped the VFO knob from 28.120 to
28.119.40 by mistake during the snapshots, but that doesn't have any
effect on the fact there is this big wide scary 8-9khz wide signal ~
30 khz down from VFO A that is tracking my main VFO.

What is going on, has my K-Line been invaded by something? If so what
and how do I fix it?

Re: [Elecraft] K3 8khz wide sig tracks VFO A ~30khz lower in frequency

[Eric Swartz - WA6HHQ, Elecraft]

Check the connections on the BNC cable between your K3 and P3 and re-seat them. 
Also, if you have an extra BNC-BNC cable, try replacing this cable.


Also, if this BNC is run near switching power supplies etc. it can pick up noise 
like this.

Re: [Elecraft] MAC logging software

[Rick Prather]

If you are using a K3 the K3 and P3 control screens in RUMLogNG are hard to
beat on any platform.


Also, if you are a DX’er it does a superior job of tracking and displaying
DXCC slots and their status.


RUMlogNG also has much better integration with LotW and doesn’t require you
to use a 3rd party utility to do one-click LotW downloads.  It also does a
far better job tracking QSL’s by either paper or LotW.


The DX Spot screen of RMLNG is very well done and does a better job of
displaying needed DXCC entities and Slots needed that any other logger,
even the best Windows loggers.


I have used all three major Mac loggers over several years and RUMLogNG is
the way to go for a DX’er and especially one that runs the K3.

[Elecraft] KXPA100 Keying Mod

[David Robertson]

Everyone.

I had an interesting experience recently. I have a KX3 and KXPA100 ( #519 )
operating in my workshop in my basement. The rig drives my Heathkit SB220
which has the Harbach soft key mod which has less then 1 volt keying
voltage. This allows me to run up to 1000 watts no problem.

A couple of weeks ago a friend brought me his home brew linear to test.
Before connecting his linear to my KPA100 output I checked the schematic
and measured the keying voltage on his linear which was 24 volts dc at less
then 100 ma. When i connected the key line from his linear to the RCA jack
on the KXPA100 interface cable the linear went to key down without any
transmit command from the KX3. I then disconnected the KXPA100 from my KX3
and using the Elecraft keying interface cable to the linear directly from
the KX3, the linear keyed up upon transmit commands from the KX3 normally.
Well I finished testing my friends linear with 10 watts drive and
everything worked fine despite reduced output power.

Later I emailed Elecraft Support and asked them about the KXPA100 keying
problem.
I quickly got a response and a solution to the problem.

It seems that the first manufactured KXPA100 linears below serial number
700 were designed to operate the KPA500 linear which has only a 5 volt
keying voltage. Evidently,There was some problems with keying linear
amplifiers with higher keying voltages so after KXPA100 serial number 700
and above Elecraft modified the keying circuit to accommodate linear amps
with keying voltages up to 30 volts.

I either missed the memo or Elecraft didn't contact those of us about this
problem. Elecraft now has a mod kit that solved the keying problem. The kit
part number is KXPAMDKT2 and is free. It consists of a 4.7K 1/4 watt
ressistor (E500158) and a diode BV19WSTPMS diode (E560076). The diode is
surface mount and the resistor is a leaded resistor. The  instructions are
clear but some may have problems in removing a surface mount resistor (R28)
and installing the diode in its place. The resistor in the kit solders to
existing components.

The reason I am putting out this information is because I didn't know of
the limitations of the KXPA 100's keying input circuit and could have
easily blown that circuit out. Thanks for the bandwidth.

Re: [Elecraft] [KX2] DC Power

[Jim Finan]

Not all the Li Battery problems are from mishandling. 
‎
Sony had to eat a bunch of notebook batteries a few years ago because of 
improper safety protection (internally). Nikon ate a bunch of their lithium 
battery cells for the same reason. Nvidia recalled all their early tablets 
about 6 months ago for the same reason.  These are recalls I've had to contend 
with. There are many more. 

Basically the issue was that at least some Chinese (maybe others as well) 
manufacturers were cutting corners - something you can't get away with on li 
batteries. 

Ordered my KX2 very soon after the order site went a‎ctive and received it 
about 3 days later. But - I didn't order the batteries until more info was 
released about them, several days later. 

There was someone on this reflector that had a Li battery fail in an energetic 
way some months back. I'm sure it is in the archives. 

From what has been posted here, the least problematic (most stable?) chemistry 
appears to by LiFePhosphate. K9YC (Jim)  recommends them after he evaluated the 
situation.‎

‎Li batteries have been banned from the cargo hold of passenger aircraft 
because of potential problems. Plus, they aren't easily extinguished when the 
do have an energetic reaction.

As for #2, I surmise their reasoning includes:

1. Higher energy density for greater capacity for a given size and weight
compared to other lithium chemistries
2. Safe when charged and discharged responsibly, ergo the charger specified
to go with it, protection circuitry within the battery pack, and KX2
shutdown with low voltage states. No doubt they expect ham radio licensees
to behave responsibly considering the knowledge they are expected to have.
3. The knowledge that lithium ion technology has a good safety record in
laptops and cell phones, despite the very rare but widely publicized
instances of battery failures that are almost always the result of
improper charging or trauma.

Those that are still concerned have the option of using an external
battery, or cobbling together their own internal battery pack with the
chemistry of their choice. It wouldn't be hard.
