Re: [Elecraft] K3+P3+Microkeyer II

[Mike va3mw]

Another reason to start moving to a LAN based solution as it is so much simpler 
to share frequency data.  

If vendors supported it at the box level cabling nightmares start to go away.  
I'm now running raw socket connections where I can to rs232/ip converters.

Re: [Elecraft] Can KPA500 Operate Remotely?

[Mike va3mw]

Yes

Many options 

You can use an rs232 cable connected to a rs232/USB adapter on your desk 
computer. 

You can do IP, but you'll need a computer at the amp end and the operator end 
and use a LAN in between. 

You can also do serial over ip to your computer at the operator end with a rpi 
running ser2net or a serial over ip interface box. 

I control mine from a hundred miles away.

I doubt you'll have any issues with your KX3.   Just pull the batteries.

Re: [Elecraft] Elecraft Website Hacked?

[Mike va3mw]

I suspect your chrome had been hacked. 

I have seen this before with Chrome on my iPad being hacked. I had to uninstall 
Chrome from  my iPad and reinstall to solve the problem.

Well Avast  shows your system is clear, it clearly is not and you do have a 
problem on your own personal computer sadly. 

It is impossible for antivirus programs to detect all types of computer 
infections.

Re: [Elecraft] Strange KPA500 problem on 6M

[Mike va3mw]

As quoted

If the amp works on a dummy load, then look beyond the amp at this time until 
you have eliminated everything else. 

Somewhere else you are getting a voltage breakdown that is arcing and tripping 
off the amp due to high swr. An MFJ analyzer will not show that.

Re: [Elecraft] W-2 Wattmeter software

[Mike va3mw]

Correct, but you do need the initial first com port to connect the W2 to the 
computer. Then you can do a client / server connection over IP. 

I've been doing it for years.

Re: [Elecraft] Remote KAT500

[Mike va3mw]

While the spec for serial is about 8ft, I run it much further in professional 
sports timing. 

Give it a try and see if it works. If you can keep the baud rate down, that 
will help. 

To really do it correctly, you will want to run rs232 to rs485 converters and 
that will certainly solve your problem.  Www.rs485.com has the bits you need.  
You can send serial like this thousands of meters.  We do this all the time. 

It isn't as complicated as it sounds.

Re: [Elecraft] Recording CQ WW CW and SS

[Mike va3mw]

Use N1MM+ which is free to do your logging and QSORDER which is also free.  
Both these run on your PC. 

Many have done it for years like this. Each qso is logged as a separate audio 
file and it works wonderfully. 

I've done it from my remote base logging the audio locally for the past 4 or 5

What configuration did you use on your lz1aq loop?

 The LZ1AQ amplifier is NOT a differential input amp, rather it is referenced

 This can have significant issues as it relates to common mode noise.
 
 As a result of my research, I ended up with a Pixel loop.  The amp has great 
 characteristics, differential input, uses an A.C.  wallwart for low noise, 
 and the install instructions isolate the amp from any ground.  
 
 The loop interface also has a control line input from your rig, that controls 
 an internal relay, so the amp is protected when you transmit.  The loop was 
 designed by hams.
 
 The mechanical design of the loop is excellent, using welds at the aluminum 
 joints.
 
 I have no interest in the Pixel company, just a very satisfied customer.  So 
 satisfied, I bought two of them and phase them with a DX Engineering NCC-1

 Hi Paul,
 
 I can recommend LZ1AQ´s active loop antenna.
 See
 
 http://active-antenna.eu/
 
 It offers a nice variety of antenna configuration options, and it plays very 
 well here as a separate RX antenna at my urban  noisy QTH. The unit is of 
 high quality, and very well documented.
 I am using it with my KX3 and a homebrew switchbox which uses reed relays for 
 QSK switching, controlled by the KX3 PTT output taken from the ACC2 jack.

 Dear Elecrafters,
 
 I have a very small and odd shaped garden in which to play Ham Radio. 
 I have a K3 (and a K2 and... ), I run QRP CW and I was wondering if 
 anyone had experience of using active loop antennas as receiving 
 antennas to lower the noise floor. I was looking at Wellbrook's 
 Website this afternoon, and I see that their loops get good reviews on 
 EHam. I was wondering what experience you guys might have with these 
 and similar antennas.

Re: [Elecraft] Timewave DSP-599zx

I agree with Eric. You need to solve this on the rf side. 

You can using a loop receiving antenna and null out the source. Or, something 
like an ANC4.

Hi Alan,
 
 The DSP599zx may well reduce the baseband (audio) noise as demodulated; 
 BUT it will do nothing about the ambient RF pollution on 40m and lower bands.
 
 As you rightly conclude in your last paragraph no amount of audio 
 processing is going to remove the noise as received without degrading the 
 wanted signal(s).

 I have really bad noise floor issues at my home QTH in the UK, especially on

 I’ve been recommended to buy a Timewave DSP-599zx DSP filter by someone who 
 does not own a K3.
 
 My questions:
 
 Are others using this filter in conjunction with a K3 or any other rig that 
 already has good DSP capabilities?
 
 Can the Timewave product really better the already excellent DSP performance 
 of the K3?
 
 Surely if the noise is right across the band and actually on top of the 
 signals I want to resolve, no amount of processing is going to remove it 
 without severely degrading the wanted signal too?

Re: [Elecraft] For Sale Elecraft k3 P3 AND Icom IC-7600

Just about every forum is reporting this. It seems it is Codar used for 
measuring waves.

 Noise on 160 Meters
 
 It may have been there for a while, but last night and tonight, I just 
 noticed a strange sweeping/buzzing noise on 160M, centered around 1915 kHz. 
 It's definitely coming from outside my immediate location because it I just 
 got off 1913 where it was reported to be S-9 in Wisconsin, Michigan  
 Tennessee.  Looking at the panadapter  waterfall display on the Flex, it's 
 about 30 kHz wide with a rep rate of about 3 CPS.  It was S-9 late last night 
 and early this morning, but barely audible at 0930 so I suspect it is 
 propagation limited.
 
 The best way to listen is in AM mode, tuned to 1915 kHz in the evening.
 
 Anybody hear this at your location?

Re: [Elecraft] KPA500 with Icom 7100

[Mike va3mw]

I use my kpa500 remotely with my ts480 with only a ptt lead and no issues. You 
won't have an issue with your 7100.

 Hi Chad,
 
 used an IC-7100 together with my KPA500 remotely for almost a year (before 
 upgrading my remote station to 100% Elecraft, i.e. using a K3 + K3/0 
 nowadays). Worked like a charm. Did not do any special cabling except PTT and 
 coax, the KPA500 takes care of the band changes automatically with it's RF 
 sensor. The only drawback is you have to switch on the KPA500 using the KPA 
 Utility software as there is no switching signal as the K3 can provide 
 using a special macro. But I never had a problem with the KPA software doing 
 the job except you need an own remoteable serial port for it.
 
 Hope that helps.

 Hi Group,
  Has anyone successfully used the KPA500 with the Icom 7100? I use the Icom 
 7100 remotely and would like to throw some power behind it. With the 
 KPA500's remote management software and capabilities, it is obviously first 
 on my list.
  Just wondering if anyone has any tips or comments to the configuration. 
 Specifically from a remote shack perspective.
  Thanks,

Re: [Elecraft] How reliable an internet connection is needed for A K3 remote to work well?

Huh?

 If you're going to ping something, do a traceroute and ping a router a few

 When you choose to ping something like Google, it tells you about your 
 provider's network up to the first place they can get rid of your packets, 
 and every other network up to the Google server.
 
 The reason you want to look at something close is that you can either control 
 it yourself, or you can complain about it to someone you pay.  When you ping 
 Google, your provider's SLA will carefully explain that they don't control 
 the whole internet, and aren't responsible for anything beyond their own 
 network.

Re: [Elecraft] How reliable an internet connection is needed for A K3 remote to work well?

[Mike va3mw]

Run pingtest.net and make sure you have a grade A rating. You don't need much 
bandwidth as 1mbs in each direction is lots if you are the only user. However, 
latency issues will cause problems. 

As I understand it, the K3/remote uses a remoterig interface. 

The problem may not be your ISP, but the routers you are using at both ends can 
contribute to your issues just as simply. 

Btw, I have been running a remote base with a ts480 for about 8 years. I do run 
CW by hosting n1mm at the far end and using a winkeyer.

 A while back we tried Remoterig with a Kenwood radio and the CW generated was
 poor on the other end.  This was presumably from dropped packets and or
 latency issues (Comcast on one end and a terrestrial microwave connection on
 the other end).  Some dits/dahs were lost and others were prolonged, due to
 the lost stop signal.  My understanding of the remoterig protocol for CW is
 it's not very robust, with no error correction or ACKing.
 
 We got around the CW problem by using a VNC and the CW is generated at the
 host end within the VNC window, using N1MM, directly keying the radio.
 
 If we were to use a K3 and K3/remote for the radio, would there be potential
 radio control issues due to the flaky internet connection, or is there
 redundancy and/or error correction built into the Elecraft remote protocol?

Re: [Elecraft] KPA500 question 2 - remote power control

[Mike va3mw]

Tom got it for me. 

Sorry, I wasn't clear that I was using the utility already and it is clear he 
has had the same issues. 

The remote power on with the utility on a locally attached computer does work, 
but it is finicky. 

You'd think with the current age of everything be handle over rs232, that this 
would be bullet proof.

 Hi Michael,

 I take it you have the KPA500 connected to a computer?  Did you download the 
 KPA500 software from the Elecraft web site?  This allows complete monitoring 
 and on/off operation.

 This makes is sort of a challenge for remote operating.
 
 Is this normal operation or did I miss something obvious.
