Right Place – Right Time

by Mark (W8EWH)

This is the story of how I was able to introduce about 40 elementary school kids to Ham Radio and more specifically, POTA.  All by just being at the right place at the right time.

I was activating K-1518 (Maybury State Park) on the morning of May 16th while my wife was at the dentist. As I pulled into the parking lot, I saw a yellow school bus (Holy Redeemer), but no kids.  I figured they must be on a hike or already at one of the many shelters.  So, I parked, grabbed my gear, and walked to the spot where I wanted to activate.  This is a spot I’ve used before – a picnic table under several tall, mature trees with great branches for hoisting a wire antenna.  The location is on the top of a rise at the far end of an open field surrounded by forest. Turns out the shelter at the near end is where the students were, busy with whatever the teachers had them doing.  My activation spot seemed available, so I walked back to it staying well clear of the class.

Set up was straight forward (KX3 and EFHW) and I was quickly on the air on 40M.  Band conditions were good, and I quickly had my 10 contacts to make the activation.  After about 20 contacts there was a break in the action, so I switched to 20M and decided to speak to one of the teachers which, while I was activating, had brought a group of about a dozen students to my end of the field for some sort of activity.  I waived to her and introduced myself, first asking if I was in their way.  She said no, and asked if she was in my way.  Of course not.  I explained what I was doing and offered a demonstration if she wanted to bring some or all the kids over.  She enthusiastically agreed to this.

So about 10 minutes later, the teachers brought the class over to me.  I had them stand behind me in a way that kept them from getting tangled in the antenna and coax.  I introduced myself and explained that I was an amateur radio operator using a portable radio and antenna to contact other people like me as part of an activity called Parks on the Air.

In this case I said, I’m set up here in this state park which makes me the “activator”, and everyone else the “hunters”.  They thought that was funny.  I then told them about the contacts I’d already made to various states around Michigan, and this seemed to get their attention.  I then explained that I was not speaking with them, but instead using Morse Code.  They all seemed to have heard of this before.  OK I said, I’m going to unplug my earbuds, turn up the speaker, and let’s see if we can make a couple contacts.

Before I started calling CQ POTA, I explained what I was going to be sending in morse code.  That I was letting anyone listening know that I was operating from a park, so please call me, and here is my call sign – my amateur radio name.  I also warned them that just like when you go fishing, you don’t catch a fish with every cast.  You must be patient.  They understood.  I was nervous – I’ve never had an audience like this before.  But then I thought, they won’t know if I make a mistake!

It took about 5 or 6 CQ’s before I got bite.  Yes, I was starting to get a little worried!  But then we had a catch and after I finished the back and forth of the contact I said – that was Georgia – and was greeted with a cheer.  Another I said?  Yes!  I sent another CQ and right away another bite.  The kids listened to the back and forth and then I said – Kansas!  Another cheer.

I this point I answered a couple of questions (including one about how I was it that I could understand the noises they were hearing) and then the teachers called an end to the demo so that they could start a nature hike.

I finished up the activation with a handful of additional contacts on 20, 30, and 17 meters, then called it a day.  See Figure 1.  My wife was on her way home from the dentist and she would stop by so we could go for a hike before going home.

I’m so glad I had the opportunity to conduct this demonstration.  I’ll never forget it.  I hope a least a couple of the kids will remember this and become hams in the future.  I only wish I had a handout or two that I could have given the teachers so if they wanted to explore amateur radio with the class later, they’d have some background info and links.  I’ll be ready next time.

Mark’s first POTA activation with the Penntek TR-45L

An Afternoon POTA Activation with the PENNTEK TL-45L

by Mark (W8EWH)

I have a hard time resisting new QRP radios, and I have an equally hard time resisting getting outdoors when late October brings 70F (21C) temps to Michigan.  Days like these are especially sweet given we saw the first snow here last week (no accumulation – but still…). For me there was no better way to enjoy this unexpected weather gift than with an early afternoon POTA activation with my newest QRP radio, the PENNTEK TL-45L.

The TL-45L is the latest radio from WA3RNC, joining the TR-35 and TR-25 in his online store.  It’s a 5-band, 5-watt CW transceiver covering the 80, 40-, 30-, 20- and 17-meter bands.  That in and of itself is not particularly noteworthy.  But when you look at this radio, you’ll immediately see what makes it different.

The retro look for me is unlike anything I have seen in a modern QRP radio.  It frankly looks like it was removed from an Apollo Command Module.  From the front meter to every knob and switch, this radio just begs to be fiddled with.  And each knob and switch serve a function that means no longer needing to dig through menu after menu to find where the narrow filter is switched in because of nearby QRM, or so I can slow down when my CQ POTA is responded to by a slower CW call.

The speaker is located on the (left) side of the radio, a feature many smaller QRP radios don’t have, though headphones can be used via a front mounted jack.  The radio sounds great – I think the radio’s case provides a nice sound chamber.

The TR-45L comes with a couple of options, neither of which I chose to add to my order.  One is a built-in rechargeable battery (5200 mAh), and the other an antenna tuner.  I have plenty of batteries, and normally use resonant antennas.

With the Monday late morning temperature approaching 70 I packed the car with radio gear, and my wife, and we headed out to Island Lake State Recreation Area (POTA K-3315) to activate this park with the TR-45L for the first time.  My wife is not a ham but often comes with me to POTA activations.  While I set up, activate, and then pack up, she enjoys the outdoors with a magazine and crossword puzzle, and sometimes, like today, a light lunch.  Usually, once the activation is complete, we’ll go for a hike on park trails.

Island Lake is about a 20-minute drive from my house.  Its 4000 acres is a mix of open fields and hardwood forests surrounding Kent Lake and the Huron River.  Today it was warm enough that someone was using a paddle board on the lake.

I have found a set of picnic shelters on elevated ground overlooking Kent Lake as a great place from which to activate.  I worked North Pole Alaska from this location on 20M CW using my IC-705 with 10W into an EFHW last May.

Once at the shelter I set up my EFHW (KM4ACK kit) in a sloped configuration using a conveniently located mature tree and my throw line.  It was roughly in an East/West orientation. Over the preceding weekend, I added PowerPole connectors to the provided power cord, and programed both internal CW keyer memory slots.  These are activated using either dit or dah paddle when I toggle Play using the provided switch.   Of course, I did a little POTA hunting using the home antenna to familiarize myself with the TR-45L’s operation.  The learning curve is short with nothing hidden deep behind any menus.

With the radio and antenna ready to go, I set up HAMRS on my iPad, spotted myself on the POTA website, and started calling CQ POTA on 14.0615.  Over the course of the next 35 minutes, I worked a total of 30 stations on 20M and 40M (most on 20M) at which point I basically ran out of hunters.  Not bad for a weekday afternoon.  I packed up and went on a couple mile hike with my wife.

The TR-45L is an absolute joy to use.

I forgot to put it in CW Narrow mode at first, and when nearby QRM popped up, I was able to add this in with the throw if one switch. QRM gone.  (Note, this setting – wide vs. narrow filtering – must not be retained after the power is shut off or the battery is disconnected.)

It sounds wonderful.  I used the side speaker the whole time as my wife doesn’t seem to mind, although the random guy who wandered in with a laptop to get some work done on a warm fall day decided to find somewhere else to work.  There are front mounted jacks for headphones, paddles and a straight key.  Even a rear mounted jack for an external speaker.  The built-in speaker can be turned off and on via a toggle switch.  The two CW memory slots are easy to fill using your paddle.  The front meter can show power output or SWR based on toggle switch position, and you are alerted to high SWR via a front mounted red LED.

I waited a while to get this radio.  Recent supply chain issues caused unexpected delays, but it’s available for order now in factory-built form and most definitely worth the wait.  Kits will eventually be available.  Check out all the TR-45L details here.

Mark discovers an affordable case for the Penntek TR-35

Many thanks to Mark (W8EWH) who writes:

Hi Thomas,

I read with interest your posts about the PENNTEK TR-35 and liked it enough to go ahead and order one for myself. I built it over a couple of weekends of occasional work, and put it on the air. I really like it.

Since I’d like to take it out on some POTA activations, I did some investigation into a case and found the following case on Amazon:

Click here to check it out on Amazon.com (affiliate link).

 

This case fits the TR-35 very nicely. See the attached photos.

There is even room for a couple of cables to be tucked away under the mesh on the lid side. The only modification I made was to add a couple of pieces of packing foam around the top and BNC side to just keep the radio from sliding around a little. But really a person preference of mine.

I thought I’d share this with you so you can share with others that have this radio and are looking for a nice hard case.

What a great tip, Mark!  Looks like it fits the TR-35 perfectly. Thank you for sharing this!
