And then...the rains came...

I think it started raining about a month ago but the last week has been incredible.  Thunderstorms, tornadoes, hail, snow flurries, and more thunderstorms.  Ahhh..the joys of living in Tornado Alley in the Springtime.  This is not conducive to POTA activations around here, and it may be a week or 10 days before I will be able to venture out into the soggy bottom of Camp Swampy, also known as the Atterbury Fish and Wildlife Area. 

So what's a rained out, bored to death, CW operator supposed to do?  Well I have been enjoying doing some SWLing, shortwave radio listening.  I get a kick out of finding the strange and odd CW signals out there and then trying to figure out what it all means.  This week I have been logging in to a Kiwi SDR receiver in Michigan.  This one is run by Bruce Johnson KX4AZ out of Athens Georgia.  Bruce has SDR receivers in Michigan and Georgia.  The particular one I was listening to was KX4AZ/T - the T means Tustin Michigan. which is about 315 miles due north of my location.  You can tune in by aiming your web browser here: http://kx4az_t1.proxy.kiwisdr.com:8073/

On the night of April 3rd, I copied a Canadian Coast Guard transmitter located in Fort Caldonia, Nova Scotia.  The time was 22:30Z and the mode was CW.  It looked like this: 

VVVVVVVVVVVV DE VCO/B FN15

So what they were sending were 12 V's  (It's a CW way to gather attention) DE (from) VCO/B (a beacon station with a call sign of VCO) and finally FN15 (This is a maidenhead grid square reference, you can look on a maidenhead map and tell the general area of the globe the signal is coming from).  My maidenhead grid square at home is EM69.  

What was interesting is this was copied on a frequency of 6770.15 Khz.  I have done some google checking and VCO hasn't been heard on this frequency before...at least that I can find.   

The same night, I also copied a CW signal sending the same three letters over and over.  This was on a frequency of 6782 Khz and it looked like this:

ODX    ODX    ODX    ODX    ODX    ODX 

This one is a stumper.  I have checked Google, and chatGPT and I am not coming up with anything. Normally beacons will have a /B after the call sign, but this just keeps repeating the same three letters over and over.  I logged it at 22:20Z on April 3 2025.  If anyone has any idea on this one, please leave a comment. I think it is some kind of channel marker...but not sure. 

Another thing I have had fun doing is listening to some pirate radio stations that like to hang out in the 6935-6980 Khz range.  Usually these stations only pop up on weekends, or holidays.  They use names like Syco Radio, Wolverine Radio, Thunder Chicken Radio, and Appalachia Radio (Great bluegrass and bluegrass gospel) .  You can go to HF Underground forums on the web and read about the reports and their activities.  Most of these stations operate in Upper Side Band mode, but you'll also find a few running AM.  Just another way to kill time until the ground dries out. 

So today I decided to take my Norcal 40A off the shelf and get on the air with it, while it CONTINUES to rain. 

I built this little 1 watt or less radio in the fall of 1998, and I used this radio to make my very first ever CW (Morse Code) contact.  It was with a station in Mississippi on Spetember 7, 1998, from the picnic table in my backyard. KF4EWO Brian Kusler in De Soto Mississippi. I was so excited I could hardly breathe.  By this time I has been a amateur radio operator for just over 10 years, but this was the first time I had a radio that would allow me to operate in the HF bands.  Up to then all my other stuff was geared for UHF/VHF radio.  What's the difference?   I can use UHF/VHF to communicate across town, maybe a few counties.  With HF, I could work the world.

My sorry antenna for this first contact was a pair of 22 gauge telephone cross connect wires that I had made a rudimentary dipole from and had slung it over the roof of my house.  I tuned it with a antenna tuner I also made from a kit, the venerable ZM-2 Z match antenna tuner.  

I get the old girl off the shelf probably once a month to make sure it's still working, and every contact with it is exciting to me.  So today while messing around, I tuned to 7041 Khz and heard a station calling CQ CQ DE N0SS MOQP  - this was N0SS The Mid Missouri Amateur Radio Club.  MOQP meant they were looking for contacts to log in the Missouri QSO Party.  A QSO Party is normally run over a 12-24 hour period, and the mission is to make as many contacts as you can in the time period.  Then you turn in your logs and we see who wins.  

This is what the Kiwi SDR screen looks like at Tustin Michigan.  That yellow line under the green bracket thingie is me calling CQ from home, and that's my 1 watt signal in Michigan!  

Kiwi SDR - KX4AZ/T in Tustin Michigan

This next picture is N0SS working KB9BVN in the Missouri QSO Party, he gave me a 599 signal report, which is about as good as it gets.  Likewise he was loud and clear here in New Whiteland Indiana.  It's amazing that my one watt radio is making it in good shape.  The SDR in Michigan is 315 miles, and the N0SS station in Jefferson City MO is 335 miles as the crow flies. 

A little bit later I worked station W0I, which is a special event station participating in the Missouri QSO Party.  It is being operated by Kevin in Olathe Kansas.  He gave me a 599 signal report and I returned the same. We were on a frequency of 7044 Khz.  This time we're out 510 miles! 

OH BOY...hung out a bit longer...used the Kiwi SDR in Michigan to visually see the CW stations on 40m.  Wow what a nice aid to operating...but is it cheating?  Only the shadow knows.  So I just tuned to 7038 Khz and managed to get a 599 from station W0R in Missouri.  He was a solid 599 here as well. 

Well that's about it for today, I think I will continue playing on the air with the Norcal 40A and using the Kiwi SDR that KX4AZ/T has up for some extra help. I hope my next post will be a report on my next great outdoors adventure. I'm tired of being cooped up in the shack.  Thoughts and prayers going out to all the flooding victims, this has really been a wet few weeks and from the vids I have been seeing, the flooding is terrible in many parts of the central US.

My 50th Park Activation!

Obey the Rules or Pay the Fines

Sometimes reaching goals can be so exciting, and so anti-climatic at the same time.  Today I completed my 40th POTA activation at US-4183 Atterbury Fish and Wildlife Area.  That makes 50 times I have gone to a park and made at least ten contacts. The goal of 50 activations was something I was sure I'd hit last year but life isn't all ham radio and playing outside, other things happen.  As you can see here, my operating position was on the shore of beautiful, bug infested, Beaver Bottom Lake in the Atterbury Fish and Wildlife Area.  This place is almost uninhabitable in the early summer, as the bugs are so thick you're certain to be carried off and drained of all bodily fluids. This time of year the lake is clear of weeds, the bugs haven't come up out of the ground yet, and it's just a great place to spend an afternoon hour or two enjoying the hobby of amateur radio. 

So today I loaded up the Trailblazer as soon as work was finished at 4:15PM, traffic this time of day can be thick, and it was.  I arrived at Beaver Bottom around 4:45PM, I had the antenna up, the table installed, my chair unfolded and the 10 Watt KX-2 connected to the Eagle One antenna by 5PM.  The first contact rolled in on 14.046 Khz at 5:02PM...which is always a good sign.  The first station logged was Steve in Texas, K5SJC and I ended up with 19 total this time before I decided to pack up and head to the home shack.  Signal was getting out well.  Montana to the west, New York to the east so almost coast to coast.  I can setup the Eagle One and the coax with a couple radials in less than 10 minutes. 

DNR Supplied Ham Shack

I was very surprised to see the DNR had already installed the portable ham shacks this early in the year.  Usually this doesn't happen until mid April.  The lake was busy today, I counted close to two dozen fishermen scattered around on the bank.  This lake also has a nice aluminum walkway that provides wheelchair access to some nice spots to fish from. 

I don't think I could have asked for better weather today, it was sunny and it was warm, and not a raindrop in sight. That might change later this week, here in Indiana, this time of year can bring on some pretty treacherous weather, including tornadoes, hail storms, and high winds. 

Here's my basic setup, the KX-2 of course, my little 3D printed paddles, the round ball looking thing is an external amplified speaker to pull out the really weak ones. I found these little notebook things at Dollar Twenty Five Tree.

Well that's about all for now. Until the next adventure!

New Park for Me!

US-12023 Cikana State Fish Hatchery

The Cikana State Fish Hatchery is one of the newer parks that has been added to the Parks on the Air program. It's a very nice state property that has hiking trails, and picnic tables for observing the local wildlife.  Where there are fish ponds, there are numerous birds and other animals around for your viewing pleasure.  

The fish raised here are not for sale to the public.  These fish are for stocking the public waters of Indiana.  Indiana currently uses the site for raising bluegill, largemouth bass, red ear sunfish, black crappie, sauger, channel catfish, and walleye. 

This state property is open from dawn to dusk, and the office here is opened Monday through Friday from 8AM to 4:00PM, closed for all state holidays. 

When I got to the site, I came in off State Road 44, on my way home from Martinsville.  The entrance is clearly marked and there is a information kiosk thing about 250 yards into the property.  Behind the kiosk is a couple of picnic tables overlooking some of the ponds, and the woods.

Welcome and some information about the property

Since I was going to be using my KX-2 and the portable AX-1 antenna, I was perfectly at home at this picnic table.  I was ready to get on the air about 3PM EDT.  Like my beer glass coffee mug? 

KB9BVN about to jump into action

Spotted, on 14062 Khz, and ready to copy the POTA hunters!

So, here's where things started to not go as planned.  I fired up the KX-2 at 10 watts...in almost an hour I had worked one station.  N4CD at a park in Oklahoma.  So I shut down, and raised the Eagle One hitch mounted vertical on my SUV, tossed out a couple of radials, and tried it again. 

This was a good move, I nailed down another eleven contacts in about 30 more minutes.  Covering OK, TX, LA, MO, ID, NY, MN, SD, and FL.  Not a bad effort.  I had 12 in the log and it was time to pack up and go home.  

I checked the space weather for band conditions and today it wasn't good.  Normally I don't have any issues working DX with the AX-1 antenna...but that was not happening today.

Band Conditions: SSN:90 SFI:148 A:34 K:3  

NOT GREAT!!!

Lots of opportunities when I come back!

Homemade Battery Packs for KX-2/KH-1

Operating KX-1 on Field Day 2007 

The bane of operating portable is running out of battery power before you are ready to QRT and close the station.  Now that I am using the KX-2 as my primary out and about radio, I needed to find a way to supplement the battery situation.  I have two of the batteries that Elecraft sells, and they are about 3 or 4 years old and they work fine, but I thought I might start looking for some spares.  

Being a frugal (aka tighfisted) ham, I was deterred when I saw the pricing for brand new Elecraft batteries.  

Now I am certain they are worth every penny, as Elecraft makes nothing but good goods in my experience with them over the years.  My ham brain just insisted I dig deeper and see if I could cobble some battery packs up on my own.  This is what I came up with. 

The battery pack that is used in the KX-2 and the KH-1 is a pack made from three Lithium Ion cells, commonly known as 18650's.  If you have an EV, you probably own a thousand of them and maybe did not know it. 

The Lithium Ion cell is not to be confused with the Lithium Iron Phosphate batteries.  The Lithium Ion batteries used by the KX-2 and KH-1 are not smart batteries.  They have no built in battery management chip (BMS), so you CAN overcharge them, and they CAN catch fire. 

I found these battery packs on Amazon.  They were marked about $32 for the pair. I think they are $39 now so keep an eye out. 

https://www.amazon.com/dp/B0BJ5QJ2GS

The power connector for the KX-2 and KH-1 is a male DC plug, 5.5mm by 2.1mm in size.  So I bought a bag of plugs, snipped off the 2 pin connectors on the batteries and soldered on the DC plugs. 

https://www.amazon.com/dp/B083J24LTZ

You need to do some thinking ahead on this.  I used a piece of shrink tube on each of the two connections, and then I used a bigger piece of shrink tube to cover the connections and help to support the connection at the plug.  Harbor Freight sells a fantastic little heat gun that is perfect for shrinking shrink tube, shrink wrap or softening hot glue.  It runs about ten bucks. 

Super Cheap Harbor Freight heat gun

So basically for less than fifty dollars I was able to make two spare battery packs.  I charge them with the Elecraft Tenergy Lithium Ion charger that I bought with the KX-2.  Any smart charger that is acceptable for use with Lithium Ion batteries will work.  Never leave Lithium Ion batteries on the charger unattended.  They ARE a fire hazard. 

Still cold here this week...we're promised temperatures in the 60F-70F range next week.  Fingers crossed.  Looking forward to getting back out in the parks and operating. 

On another note these batteries run my K1, K2, KX-2, and Hilltopper rig very well, apparently they all accept the 5.5mm by 2.1mm DC power plug.  Nice.

It was 60 Degrees today...I just had to POTA

Got off work at 4PM, loaded up and headed south to US-4183 Atterbury FIsh and Wildlife Area, which is about 25 miles away.  By the time I got there, and setup my station, it was 4:40PM.  

KX-2, Paddles and Contact logbook at the ready

I chose the Mink Meadow Marsh as my operating site today, it's paved, dry, surrounded by trees, and easy to get in, and easy to get out. 

I started calling CQ POTA at 4:40PM on 20m, choosing 14.062 Mhz, and I had my tenth contact at 4:53PM.  That's got to be some kind of record for me.  This is the 39th time I have activated this location.  One more and I get the "Repeat Offender" award from POTA. 

By the time I logged number ten, the temperature had dropped to 57F and the wind was starting to pick up. We are still in Eastern Standard Time here until March 9th, so I decided to go ahead and call it an outing and started packing up. 

My entire station fits in a medium sized Apache protective case from Harbor Freight.  The case is full of foam squares you can pick out to form fit your gear.  The outer shell is thick plastic of some kind, is waterproof, and can take some rough handling. 

KX-2 Station in a Apache Case

My poor SUV is in need of a serious bath, I promise on the way home I will run this filthy beast through the car wash.  I have three stickers...one is for Parks on the Air, one I got from the park office in the Great Smoky Mountain National Park...we actually did walk on the Appalachian Trail for a few hundred yards.  The Apple...well that was put there by my son N9AWM.  He knows I am not a fan of Apple and he thought this would be a nice way for me to show the world how much I like Apple. It does make me seem more hip and cool...something I can use more of. 

Also, on a final note, on Sunday our newest Grand Daughter  was born.  She's just wonderful and cute and we can't wait to get our hands on her later this week.  Mom and baby doing well...dad is hard at work. With 13 kids, you have to stay ahead of the curve.  

Until next adventure!

What a day for a QSO

 

Here it is, February 24th, and I can see Springtime from here.  I had hopes of maybe going to the park today but the temps only got to the low 50's briefly, and then the sky got overcast and now it looks like some rain may be headed our way. 

In preparation for another Parks on the Air season, I spent most of yesterday afternoon making up a couple new battery packs.  One for the Elecraft KX-2 and one for my Elecraft K1.  Both are nice smallish radio that are easy to take outdoors and operate.  My K1 is the K1 I built in May of 2002.  I purchased the kit from Wayne Burdick N6KR as he was at Dayton Hamvention selling Elecraft wares.  Wayne is a co-founder of the Elecraft company, know for their high quality amateur radio transceivers, amplifiers, and antenna accessories.  My K1 is serial number 1205, and it covers four bands - 15m, 20m, 30m, and 40m.  So it comes in real handy for Parks on the Air. 

I got these batteries from Amazon.  They are 3 cell lithium batteries made with the ever popular 18650 lithium cell from China.  The come with a two pin connector, and the radios need a 5.5mm by 2.1mm Male DC Power plug.  So I had to cut off the two pin connectors and solder on the male plugs.  Not real pretty but works very well.  The battery pictured here fits in my Elecraft KX-2 radio. 

KX-2 Spare Battery

The other battery I made is for my Elecraft K1 radio, so I put a longer cord on it. 

These batteries are 3.7vdc Lithium cells, commonly known as the 18650. If you own a Tesla, you're familiar with these as there are hundreds, if not thousands of these in some models.

Three of these calls in this configuration will deliver 12.3vdc fully charged, and you should recharge them when that drops below 11.1vdc,  As a rule of thumb you don't want to run them down much below 10vdc as it will cause them to wear out prematurely, and nobody has time for that.  So today during my lunch break I got out the old K1 and a set of vintage Ten Tec CW paddles, and got on the air.  The battery performed very well.  I was able to make 16 or 17 contacts with various park operators in about an hour.  Battery started out at 12.1vdc.  Then I tuned to the 30m band (10.117 Mhz) and started calling CQ and was answered by Tom Johnson K8TLJ over in Bloomingdale Ohio.  He's located in East Central Ohio...about 20-25 miles from West Virginia and not too far from Pittsburgh.  i was running 4 watts of power to my attic dipole antenna.  The K1 has an antenna tuner built in, so I was able to match the radio to the antenna.  Tom and I chatted for close to 20 minutes, he's a retiree, and has quite a nice station setup. 

Tom Johnson K8TLJ of Bloomingdale Ohio

We carried on for about 20 minutes and we covered the weather, our ages, what we do for work, and what kind of station setup we were running.  It was a great QSO and I will make sure to send him a QSL card in the US Mail tomorrow. 

I just looked at the weather (WX in ham terms) and it might hit 60 this week...but it'll be raining. So no Parks on the Air for right now, but it's getting close! 

My K1 station today, with vintage Ten Tec Paddles 

Fun facts about Bloomingdale Ohio:  The village was formed between 1816 and 1822 and in 1850 the population was 184.  Population peaked at 339 in 1950, and sits at 135 as of 2023.  It is located in Jefferson County Ohio on the border of West Virginia.  50 Miles east of Pittsburgh PA.

Bloomingdale is the site of a Camaldolese monastic community at Holy Family Hermitage, part of the Congregation of Monte Corona. 

Best 73 and here's to better weather soon!!
