[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   QSB needs to have a metric associated with it.  Today it was slow 
and covered about 4 S units.  On some ops it was as deep but there was 
less variation.  The fluctuations were never fast enough to cut up 
characters so copy was easy enough.  On twenty meters reports were S6 at 
best but signals popped out from a quiet band. Forty meters held more 
noise with more QSB; slower but just as deep as before.


   The forecast cold front from the north has taken hold.  Snow with 
daytime temperature in the teens in North Dakota while there were 
milder, but locally chilly, temperatures from the South. Hooded 
sweatshirts in Tuscaloosa are not normal for mid-November.



  On 14050.5 kHz at 2200z:

W0CZ - Ken - ND

AB9V - Mike - IN

K6XK - Roy - IA

NO8V - John - MI

K4JPN - Steve - GA

K4TO - Dave - KY


  On 7047.5 kHz at z:

K6PJV - Dale - CA

W0CZ - Ken - ND

K4TO - Dave - KY


Until next week stay well,

    Kevin.  KD5ONS




May cycle 25 speed its way onto the sun.

Re: [Elecraft] KAT500 remote

[Michael Walker]

Hi Hans

We need more information.

If you are using the remote client, there are a few things to set up.

First, the local software needs to be running on the PC that the AMP is
connected to

Have a look at the Port Number that the KPA500 software is listening on.
The default should work ok.

Now, run the same software on the remote PC and when you start it up, you
need specify the IP address and the port of the remote PC.  If you have a
VPN setup, that is great.  If not, then you need to do a port forward
through your router and you need to know the IP address of your Router.

This is pretty high level and I do not know your network expertise.If
you understand all I wrote, then you will know what to do.

If not, then you will need a bunch more details from  us.

It does work as I have used it for years like that.

Some hardware noise blankers are very effective at reducing line noise 
and other impulse-type noise, provided there are no strong signals 
within the 15 kHz + NB bandwidth. (My old FT-1000D, for example.) With 
appropriate firmware, could the K4 NB achieve that kind of performance? 
Could the strong signal limitation be overcome by having the SDR detect 
noise in a slightly different frequency range, like just outside a ham 
band during a contest?

[Elecraft] 11-10-2019 SSB net

[Eric Lanzl]

Here is the list of stations checking in today. From last week's list, I need 
to correct one error it should be K7BRR instead of N7BRR. Thanks again to the 
relay stations who make it possible for more people to check in to the net. 
Propagation was a little bit better today than it has been in the past. Also a 
welcome to the first time check in stations. Always nice to have new people 
checking in. The net meets on Sundays at 1800Z on 14.303.5. Everyone is welcome 
to check in.

Similar, but with finer-grain control. The K4 has 3 preamp settings and 8 
attenuator levels per-band/per-receiver. As with the K3S, an LNA (low noise 
preamp) is available for each receiver on the highest bands. Built-in 
transverters will have their own LNAs optimized for specific bands.


> 2.  Noise blanking and noise reduction effectiveness relative to the K3S?  

The K4, being an SDR, provides access to a different class of wide-band NR and 
NB algorithms. In HDR mode (i.e. with the KHDR4 module installed and enabled), 
per-receiver hardware I.F. blankers can be switched in, similar to those in the 
K3.

There's also narrowband, DSP-based NR and NB, similar to that available on the 
K3. You'll be able to combine the various modes to best effect. Since the user 
interface is more versatile (graphic LCD), we can provide both simple and 
customized NR and NB setup. 

The noise blanker for the panadapter is linked to noise blanker setup on the 
radio, so only one operation is needed to turn on both. (This is in contrast to 
the K3 and P3, where independent setup is required.)


> Will noise reduction be disabled on digital modes as does the K3S?

Yes.

Wayne

Re: [Elecraft] KPA1500 Display Color

[Michael Walker]

Wow

Dave has really spiffed up his Node-Red control panel.  :)  I need to do
some work on mine.

I have done the same thing to control my KPA500.

As there is no 'off the shelf' remote control solution, using a PI, some
bits and Node-Red is the next best thing.  You can do it even if you don't
own a soldering iron.

Re: [Elecraft] KPA1500 Display Color

[Dave]

I use a software called Node Red running on a Raspberry Pi talking to the 
KPA1500 on the network. This allows me to control and monitor the amp from a 
web browser. Customizable colors and layout. 

This will also come in handy for those who run their radios remote.
I find I use it more than looking at the amp or using the remote app.

I have a picture of the Node Red layout on my QRZ page.

[Elecraft] KPA1500 Display Color

[ockmrzr]

I just purchased a KPA1500; I had been using a KPA500.  It was "plug and
play!"  I disconnected the 500 and plugged in the 1500, updated the firmware
and everything worked.  Only have used for a day, but I already love it.

 

One exception, the color of the display.  It's light blue, as opposed to the
yellow/orange of the 500 and the K3.  I did a quick read of the manual, nil,
and did a Google on changing the color, also nil.

 

Is there a way to change the display color to match the K3?  Or, am I stuck
with light blue?

Re: [Elecraft] Battery pack not powering K2

[oz6abm]

Thanks for the good advice. I have now seen the voltage drops to 2.3 V on the 
battery when the K2 is powered on, even though it's close to 11 V charged.
So I have ordered a new battery and will see if that resolves it.

Frank,

Yes, that is the battery supplied by Elecraft.
If you do not have the battery installed, you may also be missing the thin foam 
strip that is to go between the battery and the bracket. 
Nothing really special, and if you have some of that material on hand, just cut 
it the size of the battery.  The foam pad makes the battery a bit more secure 
when installed in the bracket (i.e no rattling).

Re: [Elecraft] K-4 features

Hi Wayne,

Do you have any information about:

1.  Sensitivity or noise floor of the K4 relative to the K3S?

2.  Noise blanking and noise reduction effectiveness relative to the K3S?  In 
the regard, will noise reduction be disabled on digital modes as does the K3S?

Hi Art,

RF gain and squelch are per-band, per-receiver, as are the preamp and 
attenuator controls. 

There's an AF gain control for each receiver that applies to all bands. 


> Also, what amount of reduction in db will the Attenuation provide?

Attenuation ranges from 0 to 21 dB in 3 dB steps. There are also three preamp 
settings per band (off, 1, 2).

Wondering if the K-4 will remember settings of RF/AF gain per band?

Also, what amount of reduction in db will the Attenuation provide?

Thanks.

Re: [Elecraft] Battery pack not powering K2

[hawley, charles j jr]

I had my first battery last about 5 years until it wouldn't turn on the radio. 
It started to leak on one corner, so I was glad to get it out of there before 
it got on anything. Do you measure the voltage when the K2 switch is turned on? 
Mine was about 3 volts when the rig was turned on, but obviously dark.

Subject: [Elecraft] Battery pack not powering K2

Hi,



I hope someone can help me here. I have K2 with the internal battery kit.

I have used this radio with the battery for many years, but now I have a 
problem.

When I power up the radio with only the battery it is dead, no display nothing.

When I apply a PSU it works fine.

I have checked all the connections P3 (Aux) and the Int. Battery switch on the 
back panel is ON.

Anyway, nothing has changed since it last worked.

When I check the voltage on the battery terminals it says 10.5V. I get the same 
reading on the P3 connector, so power is reaching the radio, but the radio is 
not powering up.



Any suggestions?



Thanks

Robin

Hello Robin,

10,5 Volts is very low for a 12 V.lead-acid battery. Try to load it with
a lamp or resistor and measure the voltage at the battery again under
load condition. I doubt that all cells in the battery are good. The gel
in these batteries can dry out, which is killing them.

There is also a series diode in the supply-line to prevent damage due to
reverse connection of a power supply that at least has a voltage drop of
0,2 volts. I don't recall on what voltage the K2 will cease to work.

Hello Robin,

...

reading on the P3 connector, so power is reaching the radio, but the radio is

I had the same problem a few years ago. Charging with an external charger seemed to work. 
But the transceiver switched off very quickly, even though there was still enough voltage. 
Finally, after 10 or 11 years of use, I exchanged the battery for a new one and everything 
was fine again. Knowledge: Lead batteries don't live forever.
