Project TouCans Antenna Feed Redesign

 Halibut Electronics is working on a new satellite antenna kit!

This is kinda cool for two reasons, first because we've recently started attending the high altitude balloon meetups at Noisebridge. Satellite antennas came up during one of the meetings.

More tactically importanly though, the EggNogs docs inspired what be a better tuna can feedtrough for Projct TouCan's antenna! For notes, here's my original EggNogs documentation review reply:


The documentation looks great so far! I've made it to page 17/22. One thing:
 
 
For those of us with partners heavily into fountain pens, those of us who like to print out manuals on JIS B5 paper and then store them in Kokuyo Campus binders, page numbers in the table of contents would be very cool. (I know, I know, such a niche group :) )
 
Mostly though, I wanted to thank you for jogging my memory into a, (I hope), better solution for Project TouCans antenna ports. At present, they're inverted bananna plug posts. Banana plug screw terminals are tiny, and therefore somewhat problematic in outdoor environments. Here's an idea of how tiny
 

 

 
Suspending a two pound rig 6 meters up, eventually the screw threads begin to strip. We stuck with banana plugs though because the insulator around the conductor makes them perfect for mounting in a tuna fish can. Yes, I've read about how Yagis and dipoles are balanced and therefore have 0 volts across the antenna center, so theoretically you don't need insulators, but TouCans frequently hangs at angles to the ground and/or very close to the ground,  so, insulators.
 

 
Anyhow! The last figure on page 17, the one with the cool weather-proof washer, reminded me that gromets exist! With the correct sized gromet, we can put any size bolt pointing upward as an antenna connector.
 

 
And, even better still, we can source them from our local hardware store at the bottom of the hill!
 
Thanks Mark!

POTA from Gloria Dei Church National Historic Place US-10802

Nine year-old Tawnse and I got half-way to activating the park before the ML-300 Bluetooth transmitter gave up the ghost. I knew I forgot to charge something. 

Tawnse was so entranced with the walled Philadelphia park she thought we should have stayed the extra half hour we would have probably needed to activate it. 

What led Tawnse to this scheduling priority decision? Turns out the park doubles  as the neighborhood dog park. There's only one way in or out though a small and, of course, historic  cemetery. By the time the pups got to the wander-around-unleashed bit we were in they were far to transfixed to try to leave. Turns out two of the pups were aspiring radio engineers to boot .Well get to that.

Because our antenna was low, propagation wasn't great on 20m at 15:30 UTC on the East Coast next to an interstate in Philadelphia. Even so right after I self-spotted a fellow ham immediately called in from South Dakota. After that, the QSOs came in every five minutes or so on average. We talked to Louisiana, two hams from Florida (whose QSOs came in back to back, and a ham from Tennessee. 

I'm curious if the QSOs from Florida might have come from the same physical station. Ill find out when I map out the activation. In the meantime, I really, really need to think more about local-first data and how to download map tiles onto this device.  I remember that Simon Wllison has written about this more than once on his blog, so Im basically leaving a reminder to myself to go look that up. It would be nice to map things when Im offline at least down to geographic regions like, lets say, cities?

The other folks who stopped by the park were very, very nice. Also, they had dogs. Tawnse and I met two daschunds, one of which was very fluffy, and two Golden Retrievers. All of whom introduced themselves at our picnic table.

Did I mention we had a low dipole placement? This would be the bit about our two radio-engineering dogs.

The Golden Retrievers immediately caught on to our dipole positioning being just to low, and they were certain they could fix it. They first sniffed out the rolls of tarred twine laying on the ground below each of the two trees that supported the dipole. They considered pulling on the twine. Perhaps I just hadn't really put my back into it. Then, they each decided it was probably a problem with the tree, and started to climb the tree following the twine. Until they remembered that they were dogs and heh, dogs don't climb trees. Abashed, one of them gave up. The other one though… That guy! He followed the antenna out of the tree till he saw TouCans which was only about six feet up, putting the dipole seven feet up. 

He. Could. Fix. This. He leapt at the radio to see if maybe he could adjust it. Fortunately, for all of us, his vertical leap was just a bit too short.

Tawnse just giggled and giggled and giggled. You gotta love engineering dogs.

Like I mentioned before, the Bluetooth transmitter's battery died right after the 5th QSO, and that was that. We were off to pick up KO6BTY from the library and get some of the best Italian food in the world from Paesanos on 9th St.

QSO map coming soon.


Project TouCans Lab Notebook: Getting Rid of the Noise

 I finally landed at a quiet tape vs. noise  configuration for TouCans on Saturday afternoon. Here’s how.


In the picture above, the wires circled in green include the + and - power wire, (white and red respectively), and the keyer wire, (also red.) When I taped the bundle of wires including the single turn coil shown in the white wire to the side of the can, the noise from the power supply went away. I was left with only noise from the radio, (the kind I want), and a gentle hum from the power supply because it had switched into buck converter mode to step its voltage up to the required 15V! The helicoptering from the Pico-W was also almost gone.

In other parts of the project, the Pico-W has started burning through pairs of AA batteries rather quickly.

POTA from Pope John Paul II Park in Quincy, MA US-8422

 Slowly but surely, KO6BTY, Tawnse and I are making our way back to the West Coast. Last night, we stopped in Quincy, MA for the flight we thought we were going to take this morning...

It looks like we are gonna call the East Coast our headquarters for a few more days, This has however, opened up POTA opportunities. Last night, I had the chance to activate Saint Pope John Paul II Park, US-8422, in Boston just across the Neponset River from where were staying in Quincy. The park is relatively new. It was opened to the public in 2001 and commemorates the Pope’s visit to Boston in 1979. It was constructed on the site of a landfill and a drive-in movie theatre.

Setting up near the river turned out to be a wash. The park is arranged so there is fairly thick vegetation between park denizens and the river.

I did, however get to set up about 10 yards back from the river in a pleasant little copse of trees. 

First though, I had to get the spools of twine up into the trees. For that, I was happy to find that there were plenty of branches under the hedge tree row


A few minutes later, TouCans was up!


Not only was the rig spotted in Europe, but it also made QSOs in England and Portugal!

Here is the map. For the moment, it has F2 skips. Please ignore them, I will get a map without them in place soon.

LobsterCon Wrap Up

 


The weather finally started to cool down a bit the day before LosterCon started. We had plenty of sun, but it wasn’t baking hot. 

The campground, where LobsterCon was held, Thomas Point Beach and Campground, was clean and well appointed, maybe too clean. There were no rocks laying about that would fit in the end of the tarred twine spools, so we wound up launching the antenna using pine cone stoppers. We had plenty of nice, flat ground for our two tents, and managed to get Project TouCans about 20 ft up between a pair of pine trees.


TouCans made two QSOs during LobstserCon, but the really nice part was all the in-person QSOs getting to hang out with everyone. 

KO6BTY and Tawnse diagrammed TouCans on the nearby beach the first evening. Later that night, the rig reached KF9VV in Wisconsin.


 The night after that, I made a short DX QSO with M7LLS. Then, we had lobster! So much lobster!

During the flea market, we got to check out new and old kits from W1REX of QRPMe.



TouCans is definitely back up and running. Check out the Reverse Beacon map during LobsterCon.



TouCans Lab Book: It was an Inductor!

TouCans is back up and running! The culprit did in fact lie in the path between the power supply and ground in the PA chain. I didn’t see it coming though. Here’s the problem:


There was a cold solder joint on one side of the inductor. When KO6BTY and I measured the resistance across the inductor, it was infinite. When we remarked about this, 11 year-old Tawnse immediately said, that’s not what inductors are supposed to do. And yeah, she’ right. They’ supposed to conduct at DC.

Anyway, a few minutes later, we’d gone from this


Notice the magnet wire tint to the two wires whose solder joints are completely in the picture?

To this

    


Which, in turn, led to this later that evening.



The moral of the story for me? Always check the two terminal component first because they’re the easiest to fix.
    

LobsterCon Travelog

We're on the East Coast! KO6BTY, myself, and the 9 year-old, (known on the internets as Tawnse), flew out to Boston from San Francisco yesterday. We walked out of the airport to the ferry terminal! That's so cool! You can walk to a ferry from the airport. But do you know what we did then? We didn't take a ferry, we took a water taxi to a different ferry terminal! So many cool things already!

Here's the view from the water taxi.


We landed at Rowes Wharf which seems to be one of the fanciest wharf's in Boston, so.. yeah. From there we caught the ferry southeast to Hingham 


and from there made it to our camp site at Wompatuck State Park.

We're now making our war around via public transit taking the T back in to Boston South Station to catch a train from South Station into Philadelphia.

Meanwhile! KO6BTY and I have had Cesium maps built into our QSO log for a few months now—ever since the day Simon Wilison nonchalantly pointed out that Datasette queries are URLs in an office hour we attended with him—but haven't put up a demo video! Here's a video of a few of KO6BTY's QSOs from one of our recent camping trips along with their associated F2 ionospheric skips.

 

Lab Notebook: The Rockmite isn't Transmitting

 KO6BTY took over debug implementation last night. She wired the RF out from the Rockmite directly to Project TouCans antenna out and... Nothing.

Looking at the schematic, that leaves a few choices for what's going on.

My favorite for the moment, because it's easy, and because the part is actually very bent, is the T/R switch transistor:



The transistor is a 2N7000 MOSFET. Wikipedia lists its maximum current as 200 mA and I can see where we could have exceed that when the Rockmite was shaking loose in TouCans (several of the nylon spacers sheered after a fall.) Also, keep in mind that the power bump has more current traveling through this part of the circuit in any event.

After that, we'll be looking at whether or not the oscillator is still oscillating. But actually! Good news! If the oscillator weren't oscillating, the receive branch also wouldn't work, and it most certainly is working!




Lab Notebook: TouCans Debug: It Wasn't the RockMite PA Transistor

Since we returned from camping, Project TouCans has been pretty much off the air. We still have receive, a keyer, and a sidetone, but the rig just isn't transmitting.

Last week I thought the issue might be the output transistor of the RockMite. It is not. I removed the original transistor, replaced it with a new one, and to no avail! Here's the before


And after


There was no change in the operation of the rig. No signals were spotted by the RBN or either of the Utah or Half Moon Bay SDRs.



Antipodal HF Radiation: Or How Did TouCans Talk to Nighttime Australia and Japan after Sunrise in CO?

 On one of the most interesting radio days of our recent camping trip, Project TouCans made QSOs with Australia, Japan, Columbia, and Argentina, all on the same day! The QSOs to Japan and Australia were made in the middle of their night. The Japan, Australia, and Columbia QSOs were all made in a sixteen minute window beginning with VK3YV at 12:40 UTC.



What was the Propagation Mode?

While the QSOs were awesome! How did they happen? I did a bit of research. 

Spoiler: I don't have an answer yet.

If you have ideas, I'd love help on this, please comment!

Dayside stations talking to nightside stations led me to sv1uy's page on chordal hop propagation which had a nice diagram



The rest of the notes from below followed from this diagram. I don't have answers yet, but here are my notes. I've been talking with the kids about radio occultation, refraction, and of course, the Gladych research project during all of this. I'm also using it to introduce trig which will layer in with the work the 11 and 9 year-olds, (Mota and Tawnse), are doing with fractions.

This mode, (numbered page 4 of Gold's thesis), is interesting because we had plenty of scattering. Notice the mountain peaks and ridges all round us below.



Chordal Modes Introduced with Villard

And we have our first reference to Villard, which included Okinawa, and therefore two different Gladychs, Michael's Project Smoke Puff article, and Stanislaw who was the architect for the Okinwa base in 1955.




And there's a bit of a Gladych aside here that's just too difficult to ignore. Apparently Stanislaw also few planes in World War II? I knew Michael did, but this is the first mention [pdf] I've seen of Stanislaw being a pilot


Carter Manny Jr. worked with Stanislaw. Here's his Chicago Tribune obituary.

Finding Our Antipodal Point

To find the anitpoidal point, we can follow our longitude over the North (or South for that matter) where it will become the same longitude minus 180 degrees, or pi radians if that's the unit you prefer. You can see this in the diagram below where our longitude of about -107 degrees traced over the pole becomes about 73 degrees.




Meanwhile, our latitude above the equator will be used to find the same number of degrees below the equator:

37.82275 becomes -37.82275.

More precisely, we get 

37.822754°N 107.717935°W -> 37.822754°N 72.282065°E



And our anitpodal is shown below near the 70 degrees East label.


Pretty excellent discussion of anitpodal points.

Conclusions for the moment

I don't know what propagation mode we had yet. We're going to pull some ionosonde data next to see if there was in fact a 'tilt' in the ionosphere at the time of the QSOs.


Project TouCans featured on Ham Radio Workbench Episode #211 !!!

 


A few weeks ago, the 13, 11, and 9 year-old gang and I were out on our yearly camping trip, hanging out near Great Basin National Park above Baker, NV, when KO6BTY and I got to participate in a Ham Radio Workbench episode! It was a lot of fun! (It was also one of the latest nights up we had during the trip.)

If you're landing here from there, we talked about a lot of things including:

Project TouCans (page) (and in general)

POTA/SOTA

How early versions of TouCans were inspired by the OHIS

Camping

KO6BTY and my writing projects regarding one Michael Gladych (page) (general gladych) (general history of physics)

unschooling/homeschooling/parenting in general

and we got to talk to Thomas K4SWL about qrp rigs


We just made it back from our camping trip yesterday, so I hope to have a lot of updates over the next few days, and maybe some pretty pictures as well like this one of Mt. Wheeler and, of course, Project TouCans.




Threading the Valley: Australia from Colorado on 20 meters and 5 Watts with Project TouCans

 The gang and I made our first QSO with Australia this week!

The QSO came bundled with two other DX contacts made with Project TouCans—all in a 16 minute window—which I'll write about soon. Our camping site is nestled below Anvil Mountain to the East and across the Million Dollar Highway from South Mineral Springs, about two miles north of Silverton, CO. We're surrounded by peaks on all sides. Bear Mountain peak is framed in my pictures of the rig.

Project TouCans was probably 20 feet up in its dipole. This turned out to be difficult to show in photographs with the proper perspective. I finally decided to make a gif of different zoom levels of a single photo. The picture below starts out focused on Bear Mountain Peak and then zooms out to include the rig and the ground outside my partner's and my tent.


You can see the Bluetooth transmitter that brings the head phone audio down to the ground hanging from the bottom of the rig.

The campsite is gorgeous and almost completely bug free. I managed to make it out on one hike. Tawnse—the nine year-old—our puppy, and I were treated to views like this



Notice the mountains lurking very nearby in every shot.

That brings us to the circumstances of the QSO with VK3YV, the first DX QSO of that morning. Here's our campsite from a way's out showing the F2 skip path (estimated using real-time data from the Boulder, CO ionosonde), as well as the path of the QSO along the ground. 


Zooming in a bit reveals just how many peaks we were surrounded by and shows our location relative to Silverton.

So, with all those mountains in the way, how did we talk to Australia?

Project TouCans threaded the valley to the west of our campsite! Check this out!

I'll leave you with the map of the QSO so you can trace along the path at your leisure. Use the time control in the lower left corner or the slider along the bottom of the map to locate the QSO at 12:40 UTC. From there, you can zoom in and out using a mouse center-button wheel. You can also tilt by holding down the control key, and then moving the map using the left mouse button.




Update

Due to a bug in the ionosonde code that I'd immediately introduced, the F2 layer height was not 307 km as shown in the diagram above. It was in fact, 235 km over Hawaii which had data at the time, (Boulder, CO in fact did not), and which was closer to the middle of the QSO path as well. The difference in F2 height resulted in the first mountain intersection that used to look like this



with the incorrect data looking like this with the new F2 height data

Ionosonde Data

This was made possible with data collected by 

US-4408 Project TouCans POTA Activation Outside of Silverton, CO

 POTA activation from Silverton in twenty-one minutes!

Project TouCans had one of its highest ever antenna placements.


It showed in the QSO data. Check out the number of 599 reports, (white qso paths.)

(All QSOs are shown with their associated F2 skip paths.)

I'm loving the, (very real), yet very sci-fi look of what's going on with the F2 skips from this rig at this location


Most of the F2 paths actually cleared the mountain, so I didn't have to think about diffraction or other radio optics effects. VE3EID did plow just a little bit into the mountainside

It did come out the other side. (By the way, you can look at all of this on your own in the map below.)

But, if Ontario plowed into a peak a little bit, how did Puerto Rico KP3CW spot the rig? 

Turns out, it's line of sight between mountains from here



QSO Map

Here's the map you can steer around in on your own! Remember, click play in the lower left hand corner, then move the time slider all the way to the left. You'll be able to see all the QSO paths and their F2 skip paths (based on Boulder, CO ionosonde data at the time of the QSO.) If you click play again, you'll be able to see how the QSOs played out over time.


Notes

Difference in Altitude

I'm still working through getting the F2 traces to routinely emit from the ground. This time, Google Maps said the elevation here was 2982.468 m, but Cesium is happier with 2947.468 m, co about 35 meters lower than expected. Even then, we're not on the ground

Low Slung Dipoles and How Project TouCans Reached California from US-5906 on a POTA by a Cliff

 We got to camp a bit more in the middle of nowhere than we usually do while traveling across Utah last weekend. My partner found the Burr Trail Scenic Byway. I've looked for a route across southern Utah for the last several years, but had somehow missed this really nice, well-paved, little road.

We camped at the foot of an East-facing cliff, and the QSO map for the POTA reflected that fact pretty nicely:


Based on this overall map, I didn't think we could hit the West Coast because of this cliff face.


Almost all of the QSOs and spots paid attention to that cliff face. And then, there was N0OI:



How? How had the signal cleared the cliff and skipped out to Perris, CA?

Using data from the Boulder, CO ionosonde, at the time Project TouCans was spotted in California, the F2 layer skip is modeled in the gif below. Note that it clears the mesa, (just barely.)


The other skip off to the Southeast was headed to the Cayman Islands. All of the skewing around is to convince myself that the the F2 path lines up with the path to the spotting station. You'll notice that there's a slight elevation offset that needs to be fixed.

More Notes on the POTA

I blew out my knee a bit sitting on the ground outside the tent for a three hour podcast interview on Friday night, consequently, the gang did most of the station set up including deploying Project TouCans in its dipole. Throughout that process, the family pup kept me company

When the gang were done, we had what, for Project TouCans, was a fairly typical antenna height of about five feet over the ground

One really interesting aspect of this POTA was that I didn't have the ability to Internet spot myself. Frankly, I wasn't sure it was going to work out at all, and for the longest time from about 00:02 GMT 24-05-27 till 13:50 GMT on the same day, it didn't. (Yes, I was asleep for most of that time with the rig turned off.) And then! Thanks—I think—to a few neighboring POTA stations, ops started to realize that TouCans was there! It may have also helped that my first QSO with WI5D was a bit of a rag chew.

Also, while hanging out on the cliff, the gang found an interesting mineral/quartz/mica/I don't know sample of rock. It was flat, broke easily, and contained pockets of crystals that were translucent. Any ideas what this might be?



For the moment, I'll leave you with this map of all the spots and QSOs for the POTA over the course of the evening, and into the next morning. Click play, then move the time slider all the way back to the left to see all the spots and QSOs with their associated F2 skips at once. Then, you can hit play to see how it all unfolded. (Keep in mind, the overnight nothingness is included in the map. You may want to skip over that.)



As a final note, while I'm waiting for all the F2 data to come back, I've been trying to convince the gang that the F2-height datastream from the Boulder, CO ionosonde 


is in fact entered manually by a room of accountants not unlike those in John Wick, but to no avail. I guess they're just digital natives :) 


Ah! And credits to where the ionosonde data actually is coming from

Ionogram Notes about KO6BTY de JJ2JQF

 The recent pair of QSOs to Japan from Project TouCans from Great Basin National Park has me wondering about F2 layer ionospheric skip propagation again.

I got our F2 skips working for CZML. Here's a look at the skip path for JJ2JQF de KO6BTY. Notice the Earedson ionosonde is almost right in the middle


Here's the map to take a look at 


Note that the path goes for a little while underground. However, Hugyens:


Check out the mountains that can act as a knife-edge barrier creating  new source.

Japan Two Days in a Row and KO6BTY's first POTA Activation from US-0032 Great Basin National Park

 Today KO6BTY made a QSO to Japan from Great Basin National Park!!!


Not only that, but she also made her first POTA activation! She was operating from Project TouCans as KD0FNR/KO6BTY on 20 meters. Here's the QSO map, (after hitting play in the lower left corner, all the QSOs will shown for a brief moment; if you click pause you can zoom in/out and view all of them at once; continuing with 'play' will remove all QSOs and display each QSO as it happened in time during the activation):


We Must Be in Nevada... QSO de JG0AWE!!!

 


This morning at the 2nd POTA activation here, I got to talk (OK, CW), with JG0AWE again!

Just like last year!

I was using a bit more power this year. Project TouCans is running somewhere between 3 and 5 Watts at the moment.

He caught me just before the gang go the oatmeal ready, (we're camping on the edge of Great Basin National Park), On top of that, a RBN station in Japan had spotted Project TouCans about half an hour before. There wasn't a grey line between our locations, so I'm curious about what was going on, but delighted to have made the QSO!

Here's the activation in Cesium so you can see where the sun was in relation to the QSO. The QSO takes place at 14:49 near the end of the animation.

This one Weird Trick Reduces 2 S Units of Noise

 Washi tape to the rescue again!

Tuesday morning, with Project TouCans working better that it had in days, I noticed that the ends of our stranded wire antenna had begun to fray out. I grabbed a roll of washi tape from my pocket, (who doesn't take washi tape on a radio outing?), and a few minutes later, voila


The end of our antenna was no longer frayed, and nosie was down significantly! Here's a view of our activation site from the opposite angle looking out over the Great Basin of Great Basin National Park US-0032.



Twenty meters looking pretty good this morning

 The band's looking alright to Project TouCans this morning!



The map covers the following half hour table. Project TouCans is still running five watts or less.
