Shack Shake up and a New Cootie Box

I’m still a little land-locked but as my wife continues to improve after her surgery, I will be able to get a away. That hasn’t stopped me from tinkering in the shack and playing radio. Today I graduated from CWI and I am now an Alumni. For those wishing to improve their CW Skills, I recommend attending CW Innvations https://cwinnovations.net

One of the things I did today was shake up the shack a little. I had the Elecraft K3 installed at the home QTH. As I looked at the radio, I realized that it looked and felt out of place. In reality it is the best field radio I have and with that in mind I pulled it off of the desk and put it in a travel box. I like to take this radio out for my local club events like Field Day, Winter Field Day and the Support Your Parks on the Air Weekends. In its place I moved one of my IC-7300’s to the desk. The 7300 is a very versatile radio capable at home or abroad. The 7300 compliments the IC-7610 as they operate in a similar fashion.

I also made another version of my Cootie Box using a DPST light switch and a 1/8″ TRS plug cable. It cost about $15 and 30 minutes of time. Parts are from amazon:
Stereo Cable
DPST Light Switch
No soldering required as the switch has screw down terminals. Here is a shematic:

I have a male end on one side and a female end on the other. I have some paddles with the cable attached so having the female end is for convenience. The cootie box is not much bigger than the cables I normally use.

Having a male/female end allows me to coil it up.

This Cootie Box is small enough to take anywhere and allows me to work straight key events without having to bring an extra key with me. The switches I bought come in two’s so I may make another one. 73 — Scott

Another case of the doldurms

I’m in the doldurms again – radio doldurms. This time it is due to my wife having a hip replaced. It happened quickly. She saw the doctor one day and a week later she had a new hip. Over the years, recovery times have decreased but there still is a recovery time. Each day she gets a little more steady on her feet. The caveat is, I still have to do a lot of things around the house. Yes, she is worth it.

I haven’t been on the radio much. I mostly turn it on to do some head sending for my CWI class and sometimes I listen to a QSO. I try to make my codebuddy skeds as long as everything else in the house is copasetic. I try to do some of the CWI exercises at night when things quiet down. I am still doing the things, at a slower pace.

I have goals I want to attain. While in the doldrums, I have switched from my bug to a singlepaddle/sideswiper. I also use paddles and I found it difficult switching from the bug to the paddles. The bug requires a heavier hand, especially on the dit side. You have to hit it a little harder to get the pendulum vibrating. A sideswiper has a similar feel to a paddle. One thing to note, is I cannot set the contacts on a sideswiper as close as I can on paddles. It tends to mush the dits and dahs together. I am currently using a KN4YB SL-85 sideswiper. It has a shorting bar so you can use it as a single lever paddle or a sideswiper.

One negative about using a single lever as a sideswiper is it bothers my arthritis. I have it in my fingertips and it can get painful after a while. I may switch to a cootie key that bends and softens the contact. I have spent most of my CW time with paddles using a keyer. I thought in retirement I would give a straight key a go. I have been practicing and I am using my code buddies as crash dummies. They report that I am doing a pretty good job. One of the reasons I am trying a straight key, is I have 4 nice county parks in my county that are not POTA regulation. My nearest POTA parks are about 45 minutes away. So I joined SKCC and when life gets a little more normal around here, I want to start working on SKCC from home and portable.

Another goal I have is to become more conversational in CW. I have close to 2,000 CW contacts in POTA but they are just exchanges. It’s the reason I am taking a CWI Class. I want to have pass-the-time-of-day QSOs on CW. Right now my code buddies and I are around the 20-25 minute mark for a QSO. We are operating around 17 wpm. POTA exchanges I can do at 22+ wpm.

The good thing about CWI is the end of the class is not the endgame. What CWI does is give you the tools to practice and teaches you how to use them. They teach you how to diagnose any problems you have and what tools to use to fix them. Even though I am a little behind right now, when my life returns to more normal, I will be able to continue my studies.

Finally, I wish to get my code speed up to 25-30 wpm. I am one of two CW ops in my club and usually do CW during the Field Days. I am okay at around 25 wpm or so when searching and pouncing however, I would like to be able to run and hold a frequency. Once life returns… I have plans to participate in some of the CW activities such as CWTest, and I may try for a CWOps number. That may be a ways a way.

That’s the long and the short of it. I hope to see y’all out there once QRV becomes more of a reality. 73 – Scott

Cootie Box

Sometimes you got to go both ways. I recently decided I wanted to do more straight key stuff and I setteled on a sideswiper as my weapon of choice. However, I am still much more proficient with a set of paddles. Often when I go to the field for activities such as Field Day (both) or POTA/SOTA I use paddles. Now that I’m gearing up for the Straight Key Century Club (SKCC), I want to have the opprtunity to make SKCC contacts also. I do own one sideswiper key from KN5YB, Tom makes nice keys and I like the one I got from him very much. I did realize that the feel between a sideswiper and paddles is very close and since I have some nice paddles, why not make them work like straight keys.

To make a paddle into a sideswiper all that is needed is to short the Dit and Dah contacts together. This can be done with a jumper or my cootie cable https://kk4z.com/2024/01/26/cootie-cable/. While these work, I wanted something a little easier to switch back and forth so I came up with the Cootie Box. Inside is the cootie that makes the magic.

The circuit is very simple.

It only takes a few parts.

These can be found on Amazon:
Project Box
3.5mm Stereo Jacks
20 ga Wire
Note: 20 ga was far too big. 24 or 26 ga. would be better
SPST Switch
I also used solder and some heat shrink I had on hand.

I connect 5 wires on one of the jacks 2 for the Dit and 2 for the Dah contacts. One of each goes to the other jack and one of each goes to the switch. The fifth wire is the common. Since I had wire that was too big, after I cut away the insulation on the Dit and Dah contact wire, I separated the strands into two groups. I then cut the insulation off of the wires that goes to the switch and attached them to the contact wires.

I soldered the two wires together and then trimmed them before I attached the other tail to the jack. I used heat shrink to insulate the connections

Before you go any further, feed the one jack you finished soldering through the project box and thread one nut with all five wires and fasten the jack to the project box. Then thread the nut to the other jack with the three wire that go to the opposite jack. Do not thread the switch wires through the second nut. Pass the wires through the hole in the project box and solder them to the opposite jack making sure you have the Dit and Dah contacts wired correctly or they will be reversed (trust me on this one).

With the switch wired and soldered it should look like this.

Wire and solder the oppsite jack, put together, label the switch and Viola! Cootie Box.

It does not matter which end of the Cootie box is plugged into what – completely reversable. One thing I like about the box over the cable is I feel the box is more durable.

Bit by the Bug

Over the past couple of days I have been trying my new keys. One is a bug and the other is a single lever/sideswiper. I kind of switch back and forth between then as well as use my paddles. I am the zippyest with my paddles so far. So here are some of my first impressions.

Single Lever/Sideswiper. It’s okay. Coming from years of paddle use, it seems it takes more effort to run a sideswiper. Between my paddles/keys, it is the slowest. I can run around 17 wpm. I also seem to be more error prone. In single lever mode, again it’s okay. I have trouble in my head switching from sideswiper to single lever. I could probably train out of it. I think the bottom line is, if I continue to use the key, it will be as a single lever.

Next up is the bug or semi-automatic key. A bit of history. Even though I wasn’t licensed until 1995. I built a Heathkit HW-8 in the early 80’s and was interested in amateur radio since the 60’s. Back then there weren’t electronic keyers or paddles. I was very enamored the Vibroplex key. I thought they were so cool. When I finally got licensed I started out with paddles. The philosophy I followed was start with the key/paddle type you intend to use from the beginning. I have been a paddle guy since 1995 until now. With my venture into SKCC, I needed a key. I was always a little intimadated by bugs. They were complex, had to be set-up and required additional skill to run one. I held off until now.

I was in for a pleasant surprise, I got one of Tom’s KN4YB’s bugs and after watching a YouTube video by him to help me set it up. I was off and running.

The conversion from paddle to bug was pretty easy. I was worried about my dah spacing after hearing some not-so-good bug operators, but what I discovered was my years of paddle use kind of ingrained my dit/dah spacing in my head.

After some practice and adjustment I tried the bug on my code-buddy. I did forewarn him I was using a bug for the first time. I set the bug for about 17 wpm. With my current setup,by moving the weights, I can go from 17 to about 21 wpm. By altering the setup, the bug has a range from 13 wpm up to about 40 wpm. I started the QSO, and afterwards, I called him on the phone for a critique. He said he wrote down my side of the QSO and only missed one letter. It was an “S” for an “I” in the word rain. That was also an SKCC contact (my first) and I passed my SKCC number to him. Besides being able to run the bug at the same speeds as my paddles; I am comfortable with the bug at 20 wpm, it also seems easier to transition from bug to paddles and back.

It appears I am bitten by the bug. My IC-7610 and my K3(s) have both a straight key and a paddle input so I can leave both hooked up at the same time ready to go. I am in a CW Innovations class and one of my goals is to get my copy speed above 25-27 wpm. Those speeds are very doable with the bug and the paddle. Because of the size and design of my bug (model DL-151RA) It is easily field portable. I am going to get a small padded case for it and take it to a park.

A new key, a new venue, and a new adventure awaits. Retirement is grand. I am having a blast. Stay safe, play nice and 73 — Scott

The King is Dead, Long Live the King

Yesterday, I decided to list my Yaesu FTDX10 on QTH.com. Surprising to me, it sold in a couple of hours. I got my asking price and the guy I sold it to has been helpful and communicative. The radio ships out Monday morning.

I am going to take the money and get the KPA3A 100 watt amp kit for my K3(s). It is currently a 10 watt radio. I put the 3 in parenthesis becuase my radio is a converted K3 to the S. I plan to use the radio in the shack and for field days. I mainly do CW these days and the QSK on the K3(s) is sublime.

Speaking of CW, I recently received 2 keys from KN4YB. He is a one man shop that makes Bugs and keys. I was intrigued by his designs and bought a couple to try out.

The first one is a bug, model DL-151RA. It is unique in that it is a dual lever. It has one paddle for the dits and one paddle for the dahs. By moving the dit weights, you can adjust the dit speed from about 13 wpm up to 40 wpm. Mine is set around 16.

As you can see, the bug is rather compact. I have it sitting on a silicone pad on my desk and it does not move.

The other paddle I got is a Single Lever Paddle/Sideswiper. The difference between a single lever and a sideswiper (also called a Cootie Key), is a single lever paddle is used with an electronic keyer where the keyer generates the dits and dahs automatically. Note: I use the term paddle to designate a key that uses an electronic keyer and a key to designate a straight key. A sideswiper is more like a straight key where the dits and dahs are generated by hand movement. This model, the SL85 has a shorting bar which allows you to set it up as either a single lever or a sideswiper.

It is also a compact key. The workmanship is excellent and the prices are reasonable.

I started my journey into mechanical keys as the civilty on POTA seems to have taken a turn for the worse. Not as bad as SSB but not like it used to be. I decided to give the Straight Key Century Club (SKCC) a try. They only allow straight keys, sideswipers, and bugs, keys where the dits and dah are formed by hand or mechanically. My fascination for CW goes back to the 60’s. I thought bugs were very cool and wanted a Vibroplex. I wasn’t licensed until the mid 90’s and then chose an electronic keyer. My first set of paddles were Benchers. This is my first experience with straight keys.

I spent time with both keys to see which one I was most comfortable with. I went with keys that had a side-to-side motion as that was my experience. I was curious to see how well I could transition from paddles to straight keys. The answer is, not to bad. I think my years of using paddles has helped me with dit and dah ratios. The ratio is already ingrained in my head. Right now, between the two keys, I am doing better with the bug, which surprised me. However, I think over time and practice, I can gain some level of mastery over both.

What about my paddles? They are not going away. I can still send faster with the paddles and will probably use them for Field Days and some contests. It will take me a while to be proficient with keys. Setting up the bug is an art all by itself. So I am off to a new adventure. My code buddies will now have a new challenge as I try to improve my key skills. 73 — Scott

Cootie Cable

Part of my amateur radio adventures for 2024 is to become a better CW operator. What I mean by that is I want to do more than than POTA/SOTA/Contest exchanges. When I first started out 28 years ago, that’s what I did, called CQ and had a conversation. In addition to becoming more conversational, I wanted to try my hand at straight or mechanical keys. I recently ordered a sideswiper and a bug but they won’t be here fro another 2-3 weeks. I also thought about the money I had invested in paddles.

This thought process took me down to thinking about how to convert iambic paddles into side swipers. All it takes is shorting the dit and dah paddles together and setting your radio to a straight key. I wanted to make this easy. I wanted to be able to use all of my paddles on all of my radios as an iambic paddle or a sideswiper. Since this is my first journey into straight or mechanical keys, I wanted to be able to easily convert back and forth.

I made a short cable that goes between the paddles and the radio. It’s a simple operation. Starting out with plug nomenclature.

The tip is the dits and the ring is the dahs. The sleeve is the common. I had male and femlae 1/8″ stereo cables in my parts bin so I took my multimeter and coded the wires to the plugs. Basically you tie the common to the common and all the dit and dah wires together.

Twist them together, solder the joints, a little heat shrink and viola! Cootie cable. It weighs 0.5 ounces and will work with all of my radios. Now I can swith from Iambic to sideswiper in under a half a minute and use all of my paddles. See the included video that shows how it works. 73 – Scott
