EROCK ARES Digital Net

Date: 20 Aug 2015

Event: EROCK ARES Net
Organizer: KB1WFK Mike

 

Event Details:

Weekly digital practice/learning net.

 

My Loadout:

  • Yaesu FT897, Open Stub Jpole, signal link USB sound card
  • FLDIGI 3.22.05
  • FLAMP 2.2.00
  • Ubuntu 14.10

 

Loadout Performance:

  • Linux is a bear, very painful to work with.

 

Net:

  • NCS: KB1WFK
  • 1 Checkin. (Me)

 

Event results:

  • Started with PSK125 (Voice instruction)
  • Mike had technical issues transmitting.
  • I had a S9+ from Mike.
  • He got things working and we started transmitting digital traffic.
  • We tested FLMSG, but I failed to get the message to transfer into FLMSG from FLDIGI.
  • We then tested FLAMP.  Again, I had issues.  I found there is an autostart option within FLDIGI.  See image.
  • It was then time to have the Voice net on the primary repeater. <EMAIL FOR DETAILS>
  • Following the voice net, we got back and were able to transmit a FLAMP message.

 


Thoughts from the past:

  • The previous practice we worked worked with RXID and TXID. See image
    • Use TXID when you transmit to tell the listening station what to listen for.
    • Likewise, use RXID to listen to what they are telling you (and what format it is.)

 

Thoughts for Future:

  • Figure out how to interface FLMSG to FLDIGI.
  • Might try a windows machine for the next net.

MWHC AAR (After Action Report)

Date: 15 August 2015

Event: 38th Mount Washington Bycicle Hill Climb
Organizer: Cliff N1RCQ.

 

Event Details:

7.6 mile bike ride, 4618 feet of elevation gained.  Race starts at 0835.  Net Control sets up at the base of the mountain, approximately 4 miles line of sight from the summit.

15-20 Hams.  1-2 at NCS, 2 at summit, remainder along roadway.

 

My Loadout:

I came prepared to be stationed along the road as well as to be stationed at the summit.

Mobile:

  • Yaesu 8900 and Diamond SG7900, tied into car battery
  • Yaesu 2900 and Diamond NR-22L powered by a 26 amp hour AGM battery.

Handheld:

  • Yaesu VX-6R, smiley ⅝ slim duck (2m variant)
  • Yaesu VX-3R, smiley ⅝ slim duck (2m variant)
  • Baofeng BF-F8, smiley ⅝ slim duck (2m variant)

 

Loadout Performance:

  • I was stationed at the finish line, I was not able to use my mobile setup.  
  • The VX-6R with the simley gave poor performance.  I switched to my backup Diamond SRH320A and got better results.
  • I briefly considered cross band repeat with the 8900 in the car.  There is enough RF at the summit that it would have been difficult to set up.
  • The VX-3R does not have enough power to transmit to Net Control.
  • I did not use the Baofeng for this event.  I suspect it would not have worked well.  TX power is advertised at 4 (maybe 5) watts.  My SWR meter shows closer to 3w.

 

Net:

  • Net was run from the start line.
  • Stations along the road reported the first 3 male and 3 female riders to pass, along with the time (time of day).
  • I worked with the announcer at the finish line to inform him when the cyclists would start arriving.
  • I relayed race times to NCS for the first 3 male and female riders.
  • I worked with the announcer to track the last rider up.  Cars are not allowed down until all riders have made it to the summit.
  • I worked with the announcer to inform the crowd of cyclists who dropped out and returned to the base under their own power.
  • Net ran 3 roll calls.  We provided weather updates and relayed any low priority information.
  • KB1OCE was stationed in the summit house.  He had access to their weather info and relayed that.  
  • Net control rotated on and off all day.  
  • A backup NCS was assigned.
  • We had 3 frequencies assigned in the event of QRM on tactical 1.  Tac 2 and 3 were not needed, neither was backup NCS.

 

Event results:

  • 640 cyclists entered the event.  Unknown how many were present.
  • 4 dropouts during the race.  Two returned to the base under their own power, two were transported to the summit.
  • No major medical issues. 1 or 2 spills.
  • Everyone who crossed the finish line looked like they were dead.
  • Summit was 55+- degrees.  10-15 mph wind.  Intermittent clouds.
  • The cloud cover made everything damp.  I took very few notes due to damp paper. KB1OCE took notes as needed for summit/finish line
  • The start line was in the 70’s.
  • The heat lead to cramping.  Event staff did not have sufficient water at the summit.
  • First cyclist had a time of 53 minutes.
  • Last cyclist came in at slightly more than 3 hours.

 

Thoughts for Future:

  • I have purchased via ebay an Icom IC-V82.  This HT can transmit 7 watts.  It is a discontinued model.  I will probably use this as my primary public service radio.
    • I will probably purchase a Comet BNC-24 to use with this radio.
  • I brought a friend up with me.  It made the 2+ hour drive more pleasant, as well as the time on the summit.  Several of the stations on the course were staffed by a husband and wife combo (both hams in several cases)
  • It is noisy at the finish line.  A headset is nice.

Welcome Back!

Hi there!

It has been approximately fiveever since I posted to this blog. For the unaware, fiveever is one longer than forever. Likewise sixever is a REALLY LONG TIME. LIKE SEVENEVER!!!

Anyway. Where have I been? Working, moving, living and working.

I am:

1) Active with the worship team at my Church.

2) Working in Nashua NH (for a Software Company based out of San Francisco).

3) Living in Candia NH (and active with the local Boy Scout Troop).

4) Active with promoting STEM

5) A ham radio geek.

When I last posted (look below…) I was a student at the University of New Hampshire studying Computer Science. I was living with my parents, and I was dabbling with the Arduino platform.

I am now working for a software company, my office is based in Nashua NH, the team I am on is based out of Cambridge Ma. I have been with this company for 2.5+ years now. I lived in the quaint little town of Fremont for two years, and now live in the even smaller, quainter town of Candia. I put about somewhere on the order of 20000+ miles a year on my car.

My four by led cube still lives on my desk in Nashua, I turn it on when coworkers come by to ask me questions, I find it does a good job distracting them.

Anyway. I’m sure you are asking: “Why is he back all of a sudden??”

Here is the short version: A year and a half ago I got my ham radio Technician class license. Several months back I upgraded to General. In several months I will upgrade to Extra. I’ve included a link to wikipedia explaining the classes. To put it in simple terms for those who don’t want to read it all (learning a lot of stuff): if the FCC issues 100 frequencies for Ham use, then tech’s can use (that is, transmit on) 40 of them. General can use 95 of them, and Extra can use all of them. The FCC does not prohibit listening (with the exception of part of the 800 mHz range which was formerly used by cell phones (Citation needed))

Why does this matter: For me, the transition out of college and into Adulthood has been interesting (I’m not alone in this. I know this to be a universal weirdity.) Moreover, the transition out of Boy Scouts has been weird. Look at the URL for my blog. I earned my Eagle Scout. I’m not bragging here, I’m stating that to earn one’s Eagle and not serve the community, or have opportunities to serve the community, feels wrong. Service opportunities don’t walk up and slap you in the face. You have to seek them out.

Ham Radio has given me this. I spent most of the 15th on Mount Washington for the 37’th annual Mount Washington Hill Climb. Read the link, it’s worth it. I’ll dive into why I got into Ham Service at public service events later. I have worked bike races, half marathons, 5k races, hill climbs, century rides, dog sled races and parades in the last year and a half. And I have enjoyed every moment of it.

My true motivation behind this is slightly odd. The Boy Scout model is “Be Prepared”. One of the many aspects of Ham radio (there are nearly infinite aspects of Ham Radio to get involved with) is ARES, that is Armature Radio Emergency Service. The goal of ARES is to provide communication services in the event of a wide scale emergency. A great example (one that hits close to home) is the Boston Marathon Bombing. One of the lesser known details of this tragedy is that cell providers requested that users NOT make phone calls but instead send text messages. The logic behind this is when the cell towers face higher-than-average traffic they are prone to overheat and shut down to prevent damage. In most (all) cases, the cell towers shutting down is a problem. See also the Blizzard of 1978.

How do these two combine? I view community service as a chance for free practice at emergency communications. Granted: The West Rockingham ARES has a training meeting ever week on Sunday at 2000 local time (Frequency 146.850 mhz), East Rockingham is Thursday on 147.150 mHz. These weekly meetings are good practice for an emergency. I am not going to speak poorly of taking part of these meetings. I will however argue that to truly hone one’s skills, one must work CONSTANTLY to do so. The weekly meetings give this, but they the random factor. Public service gives a little more random feeling. I can tell you that 4 cyclists dropped out of the race yesterday. Two of them returned to the start under their own power, two got transportation to the summit. I can tell you that the riders with numbers 3, 5 and 80 made it to the finish line first. (You can google that one, it may take a couple days for results to get posted. (I wrote this on the 16th). (Rider 3: 53:00 minutes, Rider 5: 54.00 minutes.). What google can’t tell you is that those three riders had their positions locked in from the 3 mile mark on. The race is 7.6 miles long. Information like this is not part of our weekly training. However, details like this matter when facing a large emergency.

So why am I (trying) to reengage my blog? Any given day of the week I learn something. Be it related to Ham Radio Digital modes (with FLDIGI or APRS), building antennas, writing code in Python, IOS related or something completely random.

I have found that there is A TON OF INFORMATION regarding Ham Radio online. I have also found that it is all written in the WORST POSSIBLE FORMAT for the way I (eaglescout.jonathan) learn things. My goal is to present what I struggle to learn in a manner that is more inviting to the way I learn.

I’ll state it simple: I failed out of college once, nearly failed out twice, and left UNH without a degeree. It was studying for my General Class Licence that I learned how to study. It was exploring antenna design that I learned how I learn. My brain chemistry is not unique. I would wager that 1/10 to 1/3 people learn the way I do. I hope to provide a resource to those who learn how I do. It is my goal to share what I learn.

I follow a handful of Youtube channels. I’m not going to list them or tell you which one is my favorite, the fact that I follow them should be a strong indication that I like the content they produce.

John Green posted a video to the Vlogbrothers channel at some point today discussing his approach to gambling in Vegas in contrast to the approach his brother takes. I have contemplated a similar approach to that of John, betting as little as possible and getting as many free drinks as possible. Then my analytical mind takes over and ultimately concludes that I will still probably end up in the negative, more so than an evening at a bar. Therefore I could save money by going to a bar, or better yet, going to work and getting paid for my time.

Towards the end of the video John concludes that he made less than $4 an hour at the casino that night. At least he came out with a little more than he went in with…

At the very end of the video he brings up Hurricane Sandy. Ah Sandy. He encourages those on the East coast to stay safe. He also speculates that those without power are probably doing things other than watching Youtube on cellphones. My response as we are currently without power is: Thank you John Green, for your concern. As I am at work currently because it still has power and internet I wonder if I would sacrifice the battery to watch John Green speak of gambling? I think I would. It is dark and boring at home. Any port in a storm.

In any case, thank you John Green for your concern.

FourBy Led Cube

In my post on the 7th I used the word spoilery. This was meant to be an indication that there are more projcets in the works, and that I don’t want to post details until they are done. That said, I have an idea I am working on but have not started to order parts for. I may write up a post about that and walk through development here.

Anyway, I have another completed project to share. Do you remember the LED cube? I built another. Here is a circuit diagram. It is a 4x4x4 cube. It was a lot of fun.

Photobucket

And here are pictures of the assembly process (in no particular order…). My new soldering iron came in. I love it. It is so nice to have a good tool avalable to use.

PhotobucketPhotobucketPhotobucketPhotobucketPhotobucketPhotobucketPhotobucketPhotobucket

And here is a video of the cube working, and some pictures of the final cube.


PhotobucketPhotobucketPhotobucketPhotobucket

Remember the custom DIM (Arduino Compatable, Did it Myself) I showed you last week? I designed that board to work with my first cube, and then desinged this cube to work with that DIM. It is also compatable with the Arduino Mega.

I have six patterns (you can see them in the video). I wrote the code all on my own. The code is a heavily modified version of the code for the first cube. I still mean to post my code someday. I promise I will.

I only ran into one design issue with this board. I made an (what I feel to be a safe) assumption that two different MPN transistors would have the same pinout. Silly Jonathan. Always check the data sheet. Fortunantly the way I wired it up to begin with led to no harm to the cube. I’m glad I didn’t ruin the cube. I only ordered enough LED’s to make the cube and to have a couple spares.

  1. Total cost was about $25. The LED’s were the most expensive.
  2. I ordered 70 LED’s when I needed 64. I ruined one while assebling. None came deffective. I recieved 74. I love errors in my favor.
  3. The LED’s are really nice. I’m glad to have spares for future projects.
  4. I also ordered extra resistors and transistors. Now I have more components. Yay.

I am willing to call my exploration into LED cubes done. It was a great starting point. If I do anything else with LED’s and Arduino it would probably involve RGB LED’s and another cube. Probably a 3x3x3 this time. I think that may be fun.

More Arduinos

Over the last two weeks I have continued to play with the arduino platform and explore electrical circuit design. It has been amazing. I have so many projects in the works.

Shortly after my last post I ordered components to build my own arduino. As it is not an official Arduino board I’ll call it arduino compatable and refer to it as DIM (Did it myself).

I didn’t take pictures when the packages came in (lazy and spoilery of other projects). The beautiful thing is the cost of the components. You can build a board that is as functional as the Arduino Uno for about $15. Granted you can buy an Uno for $21 on amazon, but you lose out on the fun of building it yourself.

I ordered most of my parts through Mouser Electronics. I ended up buying the main chip from Sparkfun and paying $5 per chip to get ones with the bootloader on the board. If you can find a way to load the bootloader yourself you can buy the chip for $2 on Mouser.

I also bought a Uno R3 on amazon. The R3 has a removable chip so I develop on the Uno and then move the chip over to one of my DIM. Wait, he used plurals there. Yes. I bought components to build four DIM.

Here is a circit diagram I made for a DIM that (almost) mirrors the UNO. Also a picture of the completed board.

PhotobucketPhotobucketPhotobucket

I followed this tutorial. It was great. I didn’t do the whole etch your own board part, but the parts list was amazing. When I got to the testing part of my first DIM I ran into some problems.

This tutorial from the Arduino website is very helpful as well. This has become my go to guide. When I couldn’t get my first DIM to work I built a second DIM on a breakout board like the tutorial shows. I couldn’t get that to work either. After that I ragequit and worked with a coworker the next Monday. Turns out the first tutorial guided me to choose the wrong capacitors. I switched out for some different ones and it works. I also swaped the capacitors on my first DIM and it worked too! I also sorted out some small design issues I had with the first DIM.

I also designed a custom pinout DIM for interfacing with my LED cube. Here are pictures.

PhotobucketPhotobucket

The only issue I had with this board was I soldered the power LED in backwards. Oops. I choose to leave the reset button off of this board. I can’t reach it when the LED Cube shield is on the board.

On a side note I ordered this soldering iron yesterday. I’m looking forward to using it. I also picked up one of these guys. It should allow me to program the DIM’s without pulling the chip.

Arduino’s and LED’s

Early last week I came upon several broken Arduino Mega’s that were destined for the trash can. A breif inspection led me to believe that they would be fairly easy to fix. To spare the nitty gritty details, I fixed two of them at the cost of the third. All around, not too bad of an outcome. Two free Arduino’s that needed maybe ten minutes of soldering work. I’ll take that.

I have been wanting to play with the Arduino platform for a while now but have always been too cheap to go buy one. Problem solved.

For those who don’t know what an Arduino is, go to google and search for it. It combines the circuit design components and programing components at a perfect level for anyone to pick up and learn. Moreover it is an open source platform so if you don’t want to buy one you can buy the parts and build one. Same with the programmer. As a Linux user I love the ease of installing the programmer and using it. (Also, it seems to program the board quicker when using a linux box.)

So now that I have an Arduino (or two), I can start puttering like I have been meaning to all along. My first project was an LED Cube. I had a coworker who made a 3x3x3 LED cube. I loved watching his. I could have spent hours watching it. He used a custom made Arduino board and code he found online.

I scrounged around my small collection of components and mannaged to wrangle up 8 identical LED’s. I spent several hours scouring the internet reading everything I could on how to build an LED cube, and finally started my circuit design. I then spent several more hours fussing over my design until I was happy with it.

Back when I was working on my senior project I was building an infrared LED beacon. I used components ordered online and from Radio shack to build it. It came together very well and I learned some things about circuit design. I have found that the best way to design for predrilled prototyping board is to use graph paper and a pencil. A good eraser comes in handy as well. Here is my final design:

Photobucket

And here is a couple photos of the final product:

A photo of me taking photos of the cube:

Photobucket

And a video of it running.

So my plan is to continue developoing things on the arduino platform and to share them here on my blog. I also want to share my code with you, however I have heard that my university has occasionally claimed ownership of code written by students. Therefore I will post my code at tome point in the future when I am no longer a student
