I figured out today how to stream the audio from my PCR-1000, connected up to a Remotehams.com server, to a webpage.

The HTML code looks like the following:

<html>
<script charset="utf-8" src="http://www.umediaserver.net/bin/FlashPlayer/umsplayer.js" type="text/javascript"></script>
</html>
<body>


 <!-- player container -->
<div id="player-container">
</div>
<script type="text/javascript">
embedPlayer('player-container', {
flashvars : {
  'rtmp': 'rtmp://n8mdp.dyndns.org:5119/live/PCR1000',
  'audioMode' : true,
  'autoPlay' : true,
  'bgimg' : 'images/onair.gif'      //For audio-only streams, set your custom background; not set by default
},
size : { width: 113, height: 50 },
playerStyle : 'quick'
});
</script><br />

Flew the new 787 Dreamliner home from Tokyo. Pilot let me sit in the co-pilot's seat after the flight.

It's been quite a while since I provided an update. So much has happened since then. Let me review some of the news.

On December 31st, the ARRL's Centennial QSO Party came to an end. Here are my results:

# QSO's
Centennial Points Challenge:
2109 out of 34,424 (Top 6%)
24,482
1172
W1AW Portable Stations:
581 out of 196,150 Top <1%)
763

I never thought I would achieve that many points and the ranking that i did, As a result an am eligible for the Top Level Award. This award required greater than 15,000 points. I also achieved Triple Play status which I have yet to submit. One other goal that I achieved was to get Worked All States on CW. So the QSO Party was a big success.

Since my last entry, I mentioned that I was going to review the new pcDuino3 single board computer. This is a great SBC that I would recommend to anyone. Since October, I was able to install the ghpsdr3-alex Linux code to run one of my Softrock SDR tuners. The pcDuino3 has the horsepower and the memory to run this. Below is the system that I set up.


This setup uses the pcDuino3 with a USB hub, USB soundcard and a Softrock Ensemble II Receiver. You can learn more about how I set this up at http://www.n8mdp.com/pcduino3_sdr.php

Another little SBC that I have been experimenting is the BeagleBone Black. This little SBC rivals the Raspberry Pi. While it has the same 512Meg of memory of the RPi, it has a 1GHz ARM processor that packs a punch. So I wanted to put this to the test.

I wanted to hook up my extra Softrock RX/TX to decode digital SSTV using Debian Linux and a program called QSSTV. QSSTV supports both analog and digital slow scan.

I was able to get the BeagleBone Black (BBB) to recognize my Softrock by installing the USBSOFTROCK driver much the same way you configure it in any Linux OS. Surprisingly, it all worked and is currently on line.

That's it for now....

In addition to my review of the ODROID-U3 Single Board Computer, I am also reviewing the new pcDuino3 single board computer. This is another cool SBC that has the potential to run my Softrock Ensemble II SDR as well with the ghpsdr3-alex software.


What I like about this board is that it also accepts Arduino shields as well. For ~$77, I don't think you can go wrong considering it runs Ubuntu as well.

Today, I purchased one of the RTL-SDR products. See below. A friend of mine told me about how he used the RTL-SDR and a Raspberry Pi to receive aircraft ADS-B Aircraft Radar information. There is a real good article about this at http://www.rtl-sdr.com/adsb-aircraft-radar-with-rtl-sdr/.

So for $22 at Amazon, I thought I would buy this and try my hand at putting together a ADS-B tracker on my website. Stay tuned at www.n8mdp.com for my effort to put this together. I will likely put up the steps it takes me to get this working.

73 for now.

Wow, it's been some time since I have had a blog entry. Not much to really discuss these days.

I have been reviewing the ODROID-U3 Single Board Computer as a possible tool for serving one of my Softrock Ensemble II SDRs. This board appears to have the horsepower to run the ghpsdr3-alex software for the SDR. I will be making my decision very soon.

Last night, I made my first attempt to try the NA CW Sprint. Oh my is this crazy. You have to keep moving around the band during this contest. You can't sit on the same frequency for every QSO. I guess that is why they call it a sprint. I had 30 QSOs but some guys were up to 200-300. How do they do it?

Lastly, I continue to make great progress with the ARRL Centennial QSO Party, Here are my latest results:
Only 3 CW state confirmations away from overall Triple Play Award!! (DE, NC, WV) 
Closing in on W1AW/x Triple Play Award!!!

My good friend Alan Wolke, W2AEW, who also works for Tektronix posted this real cool video on the technical details of the Softrock Ensemble II SDR board. This is a video worth watching.

Inching closer to the Triple Play Award. According to LoTW, I have 136 confirms, 50 on Phone, 50 on Digital, and 36 on CW.

Tonight, I made CW contacts with Alaska and Montana. I'm so glad to have hit Alaska. That gets two of the hardest states, Alaska and Hawaii out of the way. Now I can focus on finishing up the remaining states on CW.

On Friday, I was able to get my Raspberry Pi and DVAP all configured for D-Star operation with my new Icom ID-51A D-Star HT. I want to thank Ken Nicely, KE3C in PA for his assistance in getting as the settings correct. My RPi and DVAP are now sitting independently in my sun room where I can get coverage all over my house and 2.5 acres. I can now sit on my porch or back yard and work the world.

My first QSO was with Carlton Stacks, KJ6OIO, in Laguna Niguel, CA, Grid DM13dm. We chatted for around 30 minutes on REF001C. Thanks for the QSO.

Here is a picture of my RPI with the DVAP software from Jonathan Naylor G4KLX:


To learn more about how I configured the RPi and DVAP for this application, please read my instructions at http://www.n8mdp.com/dvap.php.

On to the next project!!

Friday, May 23, 2014

Today, the Raspberry Pi that I ordered arrived. This RPi combined with the DVAP and Icom ID-51A will be used for a D-Star hotspot I am creating for my home. You can review my progress here and at http://www.n8mdp.com/dvap.php.


Wow, it's been a while since I posted to my blog. Been very busy at work these days as well as working the ARRL Centennial QSO Party. I'm still doing very well. As of this posting, I am ranked 496 out of 114,564 for the W1AW portable station QSO's. Not to bad!! I also need 21 more states with CW to achieve my Triple Play Award. This will be a great accomplishment for me. At last count, there have only been 1,100 confirmed Triple Play Award winners. So I am getting very close!!

Last weekend was the Dayton Hamvention. And this one was one to remember. Not just for the great deals, seeing old friends, and making new ones. No this year, it was all about the COLD, the RAIN, and the SLEET!!! One would have thought that the Hamvention was back in April, the not so good old days. Boy, it was cold. And the rain didn't help. But the sleet! I guess anything can happen in Dayton.

But the fun never stops. All of my friends got together in our flea market spot. My good friend N8OBJ John and his son Brian N8BBG, who drove in from Illinois came. John got some 'incredible deals' including engraved shot glasses for our high octane party next year. James KD8SYG and his son Josh KD8SYF joined us as well. Josh is a real go getter and loves the flea market. I just love how he really low balls people when he makes an offer to buy something. And last but not least, our friend Dave N8YQM came as well.

I took a number of pictures this year. My new ham friend Tong Huang BG1WXD who lives in Beijing China, could not come to the Hamvention this year. He plans to attend the Centennial convention in Connecticut this year. Tong and I became good friends last year when I met him in Beijing at press tour for my company. Tong and I had dinner in Beijing recently in May to share our many radio experiences. Tong is the editor of a magazine in China called Practical Electronics. I will be writing an article for him of my experiences at the Hamvention. Kind of cool to be published in China!!


This picture was taken in front of my hotel in Beijing.

Here are some highlight pictures from the Dayton Hamvention 2014. Looking forward to next year and hopefully better weather. My pictures can be seen at http://www.n8mdp.com/hamvention.php
