Len Tests a Signet Spring Straight Key

2 Comments

Many thanks to Len (W8VQ) who writes:

I have been working CW a bit in my upstairs QRP station. Last night, 40 meters was alive. Lots of POTA and general QSOs and a few SKCC. I used my new straight key. I thought you’d enjoy a critique.

I used the new key for two SKCC QSOs and three POTA hunter contacts. Here it is between my mini straight key and mini Iambic. Those are small keys, as the ruler shows;

It absolutely works, and I suspect by the way it is designed and manufactured, it will work well beyond my years. It would be excellent for travel as there is little you could do to damage it or throw it out of adjustment, short of using it to play catch.

It does not provide you with any sort of positive CLICK feedback when keying. A vintage Kent Morse Op like myself finds this a negative when keying. I like that positive click (or TAP if you prefer that description) on contact while using a straight key. This key is more of a touch-key because of the design.

If you look at the “Spring”, it’s a manufactured pseudo torsion disc spring that functions both as a spring and a stanchion for the key knob. It’s made to be both supportive and slightly flexible.

There is not enough flexibility in that spring nor space between contacts to give you enough smooth travel to get a positive click. You can get a click if you back the bottom contact screw all the way out, but it’s minimal and you have to hit the key harder than normal to get that minimal click. The spring is strong by design. This key is designed to give you more of a “Touch-Contact” that you hear via sidetone rather than feel via tactile feedback.

Some ops said that you best leave it at the factory setting, but I played with the contact set-screw in the bottom and I think I adjusted it a bit better for my fist. It comes factory adjusted with a very light touch, almost feathery. I now have it on a medium-to-light touch. There is just no “Click” or “Tap”.

Is it the best key (as one op stated in the reviews) I ever used? No.

Is it a cool and unique key that works well? Yes, as long as you don’t expect that mechanical click-on-contact that I like in a straight key for “Pounding Brass”.

There will be no brass pounding with this particular key. But I’m glad I added it to my collection. The fit, finish and manufacture is very well done, IMO. Especially for the price. And it’s unique. I may add it to my POTA kit instead of any other straight key.

What a unique key! Thank you, Len, for the mini review!

One CW Question series draws to a close after 6 months

9 Comments

by Vince (VE6LK)

Firstly, a huge shout-out and thank you to Thomas K4SWL for letting me hang out here on QRPer.com and exercise my creative writing chops, and to the community at QRPer.com for giving me such excellent feedback in my original article – both of which propelled me into this fun project.

Sometimes I begin my creative writing on a notepad with pencil, and sometimes I just type it out.

On January 20th 2024, I posted a simple question to readers of QRPer.com, If you could tell new CW learners your single best tip to learn CW, what would it be?

I was overwhelmed with the response in the comments and realized I had struck a nerve. At least one person told me that I should have bought a lotto ticket with that sort of luck, but I’ll tell you all that I am richer with the knowledge I’ve gained and shared with others as a result of the interviews I conducted with the who’s who of the English-speaking CW world.

My first key, on the right. Yes, a converted joystick. Yes, I did my exam with it.

It’s with a mixed heart that I’m here to announce that project has drawn to a close. It’s been tremendously helpful to so many people. Here’s the final episode and my personal tip to all of you aspiring CW learners.

I’m blessed to have met so many interesting people along the way and forged new friendships as a result.

Additionally, extra special thanks to Tim N7KOM, Alan W2AEW and Adam K6ARK who, along with Thomas, were my first victims interviewees where I was able to refine my interviewing and video editing process. And, Adam gave me a great idea – refine the videos into YouTube Shorts format. These refined Shorts are called 1CWQ and are the essence of each tip I recorded. The credit for the Shorts really belongs with Adam.

My entire family of keys (minus one in my truck and the others pictured above). W8BH Morse Tutor kit seen in the back of the photo. Visit my website to get your kit.

I interviewed 53 people for the series and produced well over 100 videos as a result as some gave us (you and I) more than one tip. If you missed the series, it’s not a ton of hours to binge watch. The original recordings are 2-3 minutes each and the shorts are all under one minute, or else YouTube won’t let me call them a short. You can find the Original playlist here and the Shorts playlist here.

I hope you enjoy these CW tips at least half as much as I did in recording and editing them.

One final tip, direct from my friend W5WTH who offers the following excellent advice in words better than I could ever say:

“Don’t let perfect be the enemy of good. Most CW ops are patient and can recognize a new op right away. They will most likely be happy to work you at a slow speed because they recall their personal CW journey. SKCC and POTA are the two easiest, stress free ways to make a CW QSO. Once you get the numbers and letters learned then start trying to get on the air. Don’t worry if you screw up because we all screw up and try to get better…”

I’ll add here that CW means never having to say SRI (CW shorthand for sorry) <GRIN>. Also Pat W5WTH has an excellent website too!

Handmade key left to me by VE6AB

Lastly, this is the story behind the straight key featured in all of the videos and in the main photo for this article. The key was hand crafted by my friend VE6AB, Jerry Clement, now a silent key. Jerry was a creator, maker, master machinist, backcountry hiker and camper, and photographer – a real true Renaissance Man in every sense of the word. His photography graced the covers of QST Magazine often in recent years.

At a time when CW was required for HF privileges in Canada, Jerry did his CW exam with this key and he told me once it was a real attention-getter at that testing session! Upon his passing it was bequeathed to me with instructions for me to use it and to keep my [at-that-time struggling] CW skills up. The only parts he did not manufacture were the ball bearings and the rubber feet – all of the other parts were crafted in his hands. I shall always treasure this beautiful key.

Thank you, Jerry, for encouraging me from the great beyond. DididiDahDiDah

New 3D-Printed Paddle Kit from KM4CFT

1 Comment

Yesterday, I met up with Jonathan (KM4CFT) who happens to be in town visiting family over the holiday weekend. Before our POTA activation, he mentioned that he is now selling a 3D-printed paddle kit for $34.95 on eBay:

https://ebay.us/GhLOYz
(note: this is an eBay partnership link)

Jonathan told me that he’s using the kit as a bit of a fund-raiser for a much more ambitious project he has in the works.

Jonathan gave me an early prototype of this key many months ago (see photo above) and I’ve used it in the shack and in the field. It’s a good one.

This kit version has either red or blue finger pieces.

As with all of Jonathan’s kits, he’s selling this kit via the eBay shop of Dan (W7RF). Go check it out!

Hamcation Treasure: Mike discovers and restores a mystery key!

10 Comments

Many thanks to Mike (VE3MKX) who writes:

Hi Everyone,

While at Hamcation (a great event) this year, I picked up this little Gem. It was found at one of the club tables located inside the Swaps building. When I saw it, I said, ‘wow…way cool!’

It didn’t have any markings on it and the seller said he thinks it was home made.

The hamfest bartering fun then began. He wanted $40 for it and me, being the cheaper than usual Ham, I said
‘How much do you want for this $30 dirty old key ‘ ?? He laughed but did not budge on the price.

Being from the North I calculated the price with the 35% currency exchange rate.

So I started to hem and haw….it was one of those…. Do I buy it or not. I’d kick myself after if I didn’t !!

I bought it and I’m glad I did !

After my southern vacation, I placed it on the bench for the restoration that was about to begin.

 

I took apart the key taking various pictures along the way so I wouldn’t have anything placed in the wrong spot or left over. Even something as simple as fastener lengths could make a difference placed in different spots.

I got out the Brasso cleaner, fibre cloth, Q tips, and rubber gloves. In hindsight, it might have worked better cleaning with a toothbrush. I’ll save that idea for next time!

Once the key was totally dismantled, I inspected all the parts. The black base was too far gone with scratches and chips to restore to my liking.

So I then took some 220 grit sandpaper and gave the base the once over. I went over to the local Walmart and picked up some flat black Rustoleum spray paint.

I was expecting a true flat dull black finish. What I finished with was like a flat egg shell black which to my surprise I like a lot better!

After each coat of paint (letting it dry for 24 hrs ) I then did a quick sanding with 220 grit water paper. So after three coats of paint it was done !

The key came with very small wooden finger paddles. I wasn’t a fan of those because of the size and shape. So I went into my junk drawer–sorry, my ‘ham radio treasure collection’–and found a pair of spare Begali finger paddles.

These finger paddles were acquired a few years back at Dayton, another fantastic don’t miss event ! With a little cutting I made these fit onto the cleaned brass arms of the new key.

The key was then reassembled. One thing that I did do while reassembling was to wear gloves, so I wouldn’t leave fingerprints all over the freshly restored key.

I also gave the swivel arms a few drops of WD40 which would prevent any sticking.

The reassembly went fine. The overall project took a few days to complete. I did place a small piece of cupboard lining rubber under the base of the key to prevent the key from moving on the desk when in use.

The key weighs about 5lbs, so it didn’t move much to begin with, but ya never know–!

Overall, the key has a very nice feel to it,

I still have some tweaking to do to get the paddle to my liking.
A was a fun little project.

If by chance you know anything about this key, please let me know !

Have a great day and see you at FDIM at Dayton !

New Year’s Day POTA: New VK3IL Pressure Paddle, New FT-817/818 Narrow Filter, and New TPA-817 Pack Frame!

6 Comments

I try to start each year by doing a POTA or SOTA activation on New Year’s Day.

POTA actually issues a certificate for completing an activation on New Year’s Day so there are typically loads of activators and hunters working the bands. It’s an ideal time to play radio.

This year, we had a number of family activities on New Year’s Day, but I made a little time to fit in an activation during the late afternoon at my most accessible spot on the Blue Ridge Parkway: the Southern Highland Folk Art Center.

As with my last activation, I suspected I would be operating in the dark, so I brought my LED lantern along for the ride.

Although not intentional, this New Year activation had a lot of new-to-me stuff involved!

New VK3IL Pressure Paddle

The prior evening–on New Year’s Eve–while my wife and daughters were watching a classic movie movie marathon, I used the time to heat up the soldering iron and work through a few kits and projects that had been sitting on my desk.

One of those projects was a Pressure Paddle designed by David (VK3IL).

Michael (G0POT) sent me the Pressure Paddle circuit board and heat shrink via Andy (G7UHN) several months prior. [Thank you so much, fellas!]

To my knowledge, the VK3IL Pressure Paddle isn’t available in complete kit package, but it’s quite easy to source everything yourself.

On his website, David provides the Gerber files you’ll need in order to purchase the circuit boards from your favorite manufacturer (I’m a huge fan of OshPark here in the States).

Next, you simply need to order the components. Here’s the list assuming you’re using DigiKey:

  • Quantity of 2: 732-7579-1-ND (CAP CER 10000PF 10V C0G/NP0 0805)
  • Quantity of 2: BSS806NH6327XTSA1CT-ND (MOSFET N-CH 20V 2.3A SOT23-3)
  • Quantity of 2: 311-470KCRCT-ND (RES 470K OHM 1% 1/8W 0805)
  • Quantity of 2: 1738-SEN0294-ND (RP-C18.3-ST THIN FILM PRESSURE S)
  • Quanity of 1: Three conductor wire with a (typically) 3.5mm plug (note that I had one of these in my junk drawer)

Keep in mind: the components are surface-mount. If you’re not used to working with SMD components (ahem…that would be me) I suggest buying a few spares of each in case you lose or damage one or more during the build.

It also helps to cover the finished board in heat shrink not only to protect the board and make it easier to grip, but most importantly (if you’re me) hide your electrically-sound yet unsightly surface mount soldering job.

The build might have taken me 20 minutes.

New FT-817ND Narrow CW Filter

Some time ago, I purchased a second FT-817ND with the idea of doing full-duplex satellite work. I later realized I could be taking the second FT-817ND out to the field more often if I simply had another narrow CW filter installed, so I built one.

This New Year’s Day activation was actually the first time I’d taken this particular FT-817ND and its new narrow filter out to the field!

New Armoloq TPA-817 Pack Frame

Earlier this year, I also decided that I wanted to outfit my 2nd Yaesu FT-817ND with an Armoloq TPA-817 pack frame. The idea was to experiment with building a rapid-deployment field kit around it.

This is actually one of the big projects I’m working on in 2023. I’ve yet to sort out the antenna mount I’d like to use with this frame based on how I plan to deploy it. Continue reading New Year’s Day POTA: New VK3IL Pressure Paddle, New FT-817/818 Narrow Filter, and New TPA-817 Pack Frame! →

Scott builds a base for his ZN-Lite II paddles

Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:

ZN-Lite II Update

by Scott (KK4Z)

I’ve had these paddles for about a year now but I haven’t used them much. Here is a link to my original review: https://kk4z.com/2021/11/24/n3zn-zn-lite-ii/. The reason is rather complex. they are small but because of their design, they can’t be held in the hand like some other paddles. If you put them on a table with the included Lexan base, they are so light, you have to use both hands to operate them. To me, it was a conundrum. These are very well-built, precision paddles and as smooth as any well-made paddle out there. My original thought was to use them for POTA. I was a little discouraged with their functionality, and even offered to sell them at one point — but I didn’t.

Here lately, I have been pairing my paddles with my various radios. My Begali Signature with my IC-7610, Begali Traveler Light with my IC-7300, Begali Adventure with my IC-705, and my N0SA SOTA paddle with my TX-500. I have a Penntek TR-45L on order. It is a CW-only radio that has a nice retro look. I thought these paddles would be a great match for this radio. What I want for this radio is a set of paddles that can be operated with one hand. The TR-45L is a tabletop radio https://www.wa3rnc.com/store/penntek-tr-45l-qrp-transceiver. I envision its use at a park during a POTA activation. I decided what my ZN-Lite II paddles needed was a heavier base. I ordered from Amazon a 3″ diameter, 1/2″ thick piece of steel.

I drilled a hole to mount the paddle and 4 smaller holes to mount the rubber feet. The paddle hole is countersunk on the bottom so the screw head is below (or above) the surface of the base. That way it can be used without the feet.

The holes for the feet were drilled and tapped for 8-32 thread. I had to drill the hole all the way through because I didn’t have a bottom tap. Without a bottom tap, there would not have been enough threads in the hole if I didn’t drill all the way through. When I do these projects, I basically use hand tools and in this case, I used a cheap drill press I bought from Home Depot.

N6ARA introduces the new TinyPaddle Jack!

6 Comments

A few week ago, my buddy Ara (N6ARA) sent me a prototype of his new ultra-portable CW key, the TinyPaddle Jack (TPJ).

You might recall, Ara introduced the original TinyPaddle late last year. His motivation for the original TinyPaddle was to have a super minimalist paddle that could be stored away as a spare in your kit for those times when you either forget or have an issue with your primary paddle in the field.

The TinyPaddle is a very capable little key!  Click here to read my field report using the original TinyPaddle.

Turns out, there was a lot of pent-up demand for a product like the TinyPaddle. At $15 for the kit or $20 fully assembled, the TinyPaddle is a serious bargain. Ara and his father have been quite busy producing these.

Enter the TinyPaddle Jack (TPJ)

Whereas the TinyPaddle is designed around being the most simple/minimalist backup paddle solution–basically a wee paddle with a male 3.5mm connector that plugs directly into a rig’s paddle jack–the TPJ takes it one step further.

The TPJ is essentially the TinyPaddle  with a female 3.5mm plug encased in a 3D-printed holder and protective cover.

The design is clever. The case that protects it while stored away in one’s field pack, pulls apart and is re-joined to make a very usable paddle holder.

There are actually quite a few purchase options, so Ara created this short video that describes the different components/options and how to use them:

Click here to view on YouTube.

I’ve been using the TPJ with my MTR-3B and new SW-3B. As I mentioned in my field report with the TinyPaddle, the action of this paddle is actually very precise–it almost feels like a capacitive touch paddle.

I find that the holder definitely adds to the ergonomics of the paddle (although it can actually be used without a holder, too).

Ara also created a small adjustment tool that will allow you to tweak the paddle spacing if needed. Keep in mind, this is a very simple paddle design (there are no springs or magnets) and isn’t really meant to be a primarily paddle. I do feel, however, that it will hold up quite well over time. The spacing of the contacts is so fine, I believe the stress on the paddle levers is minimal .

I plan to keep a pair with my new MTR-3B field kit (above) and use it as the primary paddle for that radio. I will plan to buy a second one for the SW-3B a well.

Highly recommend

The price of the fully assembled TinyPaddle Jack ($24) and Cable ($5) is $29 US.

This is firmly in the “no-brainer” category.

Just take my money!

I personally think Ara could charge $40+ for these and they’d still be a bargain. I know him well enough to know that his motivation is in the fun of designing these products and making them accessible to other field radio operators. Case in point: I’ve been pricing quality 3.5mm patch cables recently and I find his $5 cable to be an excellent price; even more competitive than cables I’ve seen on Amazon and eBay.

In addition, Ara even freely distributes the 3D printer files so you have the option to print your own paddle holder!

It’s obvious to me that these products are his contribution to the community that pays for itself enough so that he can continue to innovate. His designs are so clever, I can’t wait to see what he comes up with next!

Very well done, Ara!

Eric’s DIY Cootie: “Levon”

1 Comment

Many thanks to Eric (WD8RIF) who writes:

Well, if K8RAT is going to tout Hermione, I guess I need to tout Levon.

My cootie/sideswiper was inspired by an article (http://sideswipernet.org/articles/w9ok-modernization.php) by W9LA about how hams in the 1930s might have constructed a cootie/sideswiper using a ceramic DPST knife switch. I didn’t have a ceramic DPST knife switch, but I did have a nice Leviton ceramic DPDT knife switch which I used as the basis for my cootie/sideswiper. Instead of using tape for the fingerpieces as described in the article, I used Fender guitar picks.

This cootie is the key I use most often for home-based operations.

While operating in the field, I usually use an inexpensive and lightweight Whiterook MK-33 single-lever paddle as a cootie key.

Levon is a handsome sideswiper, Eric! Thanks for sharing his story and your photo!

Thanks to both of you, I feel inspired to make my own “cootie” this winter. Perhaps I’ll try to find some historic context/inspiration as well!

Any other homebrew sideswipers, straight keys, or paddles you’d like to share? Please contact me and we’ll feature your creations!

I’ve got a very special one that’ll be featured later this week. Stay tuned!

Alex builds a simple sideswiper

1 Comment

Many thanks to Alex (W3AVP) who shares this photos of his homemade cootie/sideswiper originally posted on the POTA Faxcebook page. Alex notes:

I didn’t want to lug my Begali key to the parks so I made my own using the plans from KA8VIT. Worked great! I had a little QRP key but my fat fingers would make so many mistakes. The DIY aspect of this hobby is extremely entertaining!

And I bet your “cootie” serves you well in the field! I love the simple design and the fact it even has an adjustable action. At the end of the day, keys are merely switches so are perfect for homebrewing!

If you have a sideswiper/cootie or any other key you’ve built and would like to share it here on QRPer, contact me (K4SWL at QRPer.com).

Thanks for sharing, Alex!

W1SFR’s New Portable Torsion Bar Key

Leave a comment

TBP3qtrLftFront(Source: W1SFR)

New Portable Torsion Bar Key Announced by W1SFR
Jan 12, 2016—Sudbury, VT

Many of you know W1SFR from the End Fed random wire antennas that have become very popular with QRP ops around the world. The antenna design is not new and has handed down by many hams over many years, but Steve has managed to create quite a following due to his attention to construction and only using the best of materials…all at a very reasonable price.

Now he has applied that same attention to detail and high value to his new “TBP” (Torsion Bar Portable) key. Torsion bar keys use a unique combination of construction and design to provide the CW op with a different experience…one that users are saying very good things about. All of his keys feature a contact system that allows the key lever to make a “softer” contact allowing the very slightest movement when the contact post hits the stainless contact. That not only makes the key feel less “mechanical”, but also makes it much more quiet…a feature these keys are known for.

“ I make each key by hand and top them off with my trademark exotic wood finger pieces with a signature Mother-Of-Pearl dot on each finger piece…no CNC plastic here. The torsion system allows very close contact spacing and effortless CW. The TBP represents a much smaller version of my larger keys, designed to be at home in the field or in the shack.”

The new portable key follows W1SFR’s TBKII, a single lever key and the TBSK, a torsion bar straight key.

You can see all of the keys at W1SFR.com.

Note: Steve also tells me that he lowered his prices for the Christmas season and has decided to extend them for the month of January. Click here to check out his product line.
