Chuck,

That is why I mentioned it. You cut off 17ft for the CP and the rest is the antenna. Nice way to give you both and not need a feed line.?

Daniel,

I have only had the experience with the AD9850 DDS in making the VFO project. It went together well and has been a solid stable frequency source for my projects. Also in building various QRPMe projects, a check that the receivers are actually working. For a frequency standard I bought some inexpensive small boards that are 9v powered and seem to be dead on accurate. Here is one of those. Price is right too. I just keep one with a 9v battery with a switch handy when I need to know.


As to the code. I'm rusty. Have to spend some heads down time to wake up that sleeping morse giant. I remember all those things to watch out for, being able to not get stuck on a letter and keep on... from the CWOps course I took a few years ago.

Letters pretty good, numbers a on the edge, pro signs have to work on, Q codes, some, CW strange abreviations like es for and I have some studying to do.?

I'll get there.

I agree, the building of kits, the hands on, getting things to work has always been what I was drawn to since my first crystal radio build when in junior high if I remember.

I'm signed up for the buildathon. See you online there

Re: Band Frequencies for QRS (Slow Code), CW and Morse Code Newbie Hams, and Typical Frequencies for Rock-Bound Kits

 

Oh, yeah--Daniel--? If you haven't tried 7055 kHz, most of the ops there don't go very fast--usually more than 5WPM, but I've heard 10WPM or slower, too. You don't have to stick to 7110-ish for speed reasons.

Short answer:

Anything your license will support.

Why?

When I was a Novice (Tech +, actually, but still a novice operator), I loved the 40m Novice Band. It was years later, as a General or Advanced, before I ventured out of my "safe space."? And when I did, I quickly found myself running back home to the Novices.? I was off the air for several years without a station, pretty much operating only at the University's superstation whenever I could. By the time I started back in again on my own, the Ham world had changed. The band had shifted and there just wasn't the activity in my old stomping ground.? I'm a bit sad there isn't the volume of stations in the good-ole Novice band (I think it used to be something like 7100-7150 back then), but I'm even more encouraged by what I hear in the old "General" part. I hear speed demons--the ones who answer a 10WPM station at 40+ WPM and I've heard 10WPM and below working special events and DXpeditions. (not as common, but it DOES happen). Speed isn't everything, I promise. If you can bop along at a pace comfortable to you, you'll make contacts. And if you listen in, you'll come to the same conclusion that it's everyone in the lower part of the band now.? Don't be afraid to try, that's how you get faster. And if you get run over, just ask the other station to QRS or sign off quickly. In my early days, there was more than one time I had to QRT for some fabricated reason or other: QSB, QRM, QRN, QRP, QRO, QRSS,QSY, QLF, Qsomethingorother, storm, go somewhere, alien abduction, Elvis at the door, etc.", sent 73, and signed off. I don't condone lying but I've politely excused myself when I needed to.

If you HAD to choose, I'd say anything between 7010kHz-7038 kHz for Extras and 7027-7038 for Generals is a safe bet. You'll work more DX down around 7010kHz-7015kHz. If you can buy only ONE crystal, I'd probably get it for something 7050kHz-7060kHz.? The latter frequency range is where the SKCC crowd hangs out (7055kHz, I believe, is the calling frequency), and you are very likely to make frequent contacts. They are a friendly bunch and pretty much follow the Novice QSO format.

Re: short lesson on food cans

 

Rex isn't kidding. I've built a few TT2 transmitters that way. Be thankful for the lip and up-top connectors. In the pic, you can see a Rex Super Tuna, an updated (aka toroid version) TT2, and an as-close-to-DeMaw's-version-as-I-could-do-in-2022 model. The two on the wooden bases that look like Dr. Who props (my original and the DeMaw version) were scratch built, including rotating the pcb by hand against flat sandpaper to make them round, painting the traces with enamel paint, and etching the board. Wiring the can took quite a while and was trickier than it should have been. I have another couple that aren't pictured because they aren't in the cans yet. I still need to make a base for the Super Tuna as well. (And finish about 50 other QRPME kits... Ah, grad school takes up so much time!)

A funny story about the DeMaw version-- I found a vintage can on eBay and did some research on the company. It turns out it came from a long-defunct canner that sold some bad tuna that did some folks in. I hope my can wasn't one of the bad ones. ;)? I used as many vintage parts as I could scrounge up, although I'm not 100% certain the chokes were newer Millers or actual Radio Shack ones--I had both mixed together. I think they are the exact same part (or very, very close). I worried that the ferrite properties wouldn't be close enough, but they were. I get about 300mW-350mW out.

The really beat up one was my very first. I had been a Ham a little while when I made it, but that's been every bit of 20 years ago--if not 25--I've been licensed for over 30 now. I've made a dozen or more contacts with it.? It's officially retired as it's pretty fragile. I did a bunch of things wrong when I mounted it in the can (no lip, stupid kid, limited/no tools). It survived the Joplin, MO EF-5 Tornado in 2011 (I pulled it out of the rubble), repaired it, and finally put it on the air a few years back. I'm leaving in its original state (minus a new final transistor that replaced one that broke off at some point in the jostling) and it's retired with honors, mistakes and scars and all.

Moral of the story-- it's a HECK of a lot easier to build these with the good thought Rex & Co. have put into it.?

Back in the DeMaw's day (1976), there was no such thing as an EZ-Open can so mounting a board to a tuna can was quite tedious. When it was 'Back to the Future-ized' by Doug Hendricks in his NORCAL adventures it was still tedious. I bought a 1930's canning machine from a museum in Lubec Maine and started kitting the kits INSIDE tuna cans. I remember when it would take more time to mount & wire up the connectors down in the can that it would take to build the entire rest of the kit. Even then, EZ-Open lids were a rarity usually only found on cat food cans as nobody wanted to dirty up their can openers opening up that disgusting cat food!. That's when I discovered the Dole's pineapple can. It was so easy to open and then mount the pcb on the lip that remained from the opening but I still had mount and wire those connectors down in the can. I thought: "Gee, if I could only can the kits using an EZ-Open lid, I could design an EZ-Builld TT2 with all the connections ON the PCB and make it really EZ to Build...." I could find EZ-Open lids but I had to buy like 8000 lids at a time and even then, if I could find the $$$ to buy the lids it would cost me $800 or so to have a special chuck made to seal them.

One day, I mentioned my EZ-Open lid dilemma to my can supplier and he said to check with his canning machine service troubleshooter "Maybe he will know where you could find one!". I tracked him down, told him about my tuna can adventures and he told me he had such a chuck right on his desk and he that was using it as a paperweight!! He sent it to me for free and I got my first batch of EZ-Open lids from him in the same box....all for FREE! He finagled them from a customer and then sent them to me...

Then I found a supplier where I could buy the special lids and scored on another canning machine for about $1500 that came with extra chucks for 211 & 401 cans. I took those lids to my friend the machinist and he modified both of my antique regular chucks for EZ-Open lids. I've never looked back and have had lots of FUN bringing out all kinds of kits in all 3 sized tuna cans.

Rex,

The big three Ham manufacturers have nothing on your tuna cans!? Thanks for sharing and thanks for the history lesson!

Re: QSO Ham Expo Buildathon

 

Rex,

Does the kit still use the large-size Dole can? I see in your video it is about 2" tall, but our local Walmart either had the skinnier cans or the 5-6" tall variety. I am learning about cans more and more every day and not making sweeping assumptions, LOL.

Gangue,

While Dan has been keeping you all aware of my upcoming Buildathon, I thought you might care for an update from me directly.

This will be the 9th & 10th live streamed Buildathon I've done in the last couple of for the QSO Ham EXPO. We have built all sorts of specially designed kits in the past but this Buildathon kit is the one that I am most excited about. I've tried all kinds of simple (or at least I thought so) designs but in reality only one or two hit the mark. The main problem is only having about a 2 hour window to 'Git'er done!'. This year, Eric at QSO Today put a theme to the Expo if I might paraphrase: "Now that you have your license, what's next?" I thunk hard before I pitched my idea to Eric. We would build a VERY simple transceiver in 1 two hour session and then put it on the air and try to make some contacts. Of course, this means extra problems: key & antenna. So I added a simple key and antenna to the build. But the exciting part is the operating. Imagine a BUNCH of identical rigs all operating with the same antenna on the same frequency trying to contact each other. I think this is a really cool idea. The added benefit is this should really either confirm or dispel the myth that you can't make contacts on these very simple QRPp rigs. Another neat thing would be that this could possibly be another WBB (World's Biggest Buildathon) style event the World's Biggest Buildathon & Operating Event. My friend Colin in the UK did a SOTA event where he built a Rockmite station on the summit and used it for his activation. I had 244 builders in the ballroom at FDIM build and test a minimalist 20m transmitter in a little over an hour...with no soldering irons. At the WBBOPE we will have soldering irons and then a special event activating th completed? rigs.

So I have 50 builders signed up with another four weeks or so before the shipping drop dead date. I have lots of pcbs and parts already on order so I see no problems with getting the kits kitted and out the door on time. Up on my web page for the Buildathon is a map of QTHs for the builders signed up so far, elementary docs for the new kit design and a YouTube link to a real time build of the previous incarnation of the rig. I will post a video of the complete build of the new rig just as soon as I get a board in house. I expedited a few boards so I can get them in sooner in order to generate the docs and a video of the complete build ASAP. Everyone should be well versed on the construction of the kit before we run the live stream event.

Now mind you, this is specifically aimed at new licensees so the 7110 frequency in the technician 'Novice' area should be especially receptive to slow code senders and beginners just getting on the air! I will be one of those slow code senders myself! I got to get practicing but QRPme and my wife's Honey-Do list seems to always interfere with my plans. But I will try harder!

That's all for now.

Re: RF Probes

 

Ordered and I also received my desoldering iron today with 3 spare tips. My XYL Ham is accusing all of the kit builders of putting something addicting into those kits!!!!

Gangue,

I was wondering why nobody ordered an RF Probe kit from me in a long time even after all the RF Probe emails that flew around a few weeks ago. I went looking for them, as I have more than 1 design. While the SMD probe was pretty easy to find on my test equipment button, it was unavailable as I ran out of pcbs for that kit a long time ago. I had produced that kit, from Chuck's, W5USJ, design but tacked it to another kit pcb to get the boards done cheaply. I only ordered that other kit once so never separated the design from that other kit to make individually. I replaced it with through hole design for a Buildathon and listed it as a Buildathon kit but never called it an RF Probe so I lost track of it.

Found it, renamed it and listed it as an RF Probe kit (in a test tube) under the test equipment button. I can confirm that it is W5USJ approved!

Problem resolved....

Daniel,

I used the AD9850 DDS. I have attached pictures of the board and the circuit for the pixie. The firmware I would have to track down.

I did the CWOPS Basic course a couple of years ago. It helped a lot but need more practice.

Interesting pixie link:



Links off that last one have some code.

Not wanting to stray too far from QRPMe specific topics.

I built the Sea Sprite a few weeks ago. Nice build, clean harmonics. Power about .54w as measured on one of my wattmeters.

I have register for the buildathon and ordered the kit.
I will have to see if I am confident with my code recognition to get on the air then.

I have not built the Lil Squall transiever but have built a couple of pixies and several Rockmite ][ and the topper. I have a 20m Rockmite kit waiting in a box for some time.

I modified one pixie to replace the crystal with a vfo that I put together from a nano ,a DDS chip, a display, and a rotary encoder. Worked nicely. I use the vfo as a frequency standard for my projects.

The pixie kits I have built have marginally acceptable harmonics. They need a LPF added to clean that up I think.?

Buildathons can be hectic. Depends on how fast you go. Rex moves right along and my problem sometimes I get a little behind, or my wife interrupts me... Doing it ahead of time can be done but the buildathon experience is different. In any case with Rex you always learn something new and useful about tools, tool use, or build techniques. In some cases how to fix problems you just caused. A great time is had by all.

I ordered. That weekend is only a few days before we leave FL for the weekend, We will be in IL for 2-3 weeks before we head to Colorado for the summer so worst case we will make it a buildathon with 5, 7 & 10 year old grand babies cheering me on in the burbs of Chicago, IF we aren't parked at the RV dealer 214th in line to work on that refrigerator. I think I found the sweet spot on the thermostat, but it feels like trying to align a Heathkit TV with only metal alignment tools, lol.
