I mentioned in a previous post that I recently purchased a Ten-Tec Argonaut V transceiver. It was–being honest here–an impulse purchase. This is what I get for randomly browsing the classifieds!

Truth be told, I’ve always loved the design of the Argonaut V and I knew, being a Ten-Tec, it would be a proper CW machine.

As soon as I received the Argonaut V, I put it on the air and chased a few parks and summits from the shack. It seemed to work brilliantly, but of course I was eager to take it to the field!

Around the same time, my buddy Max (WG4Z) mentioned that he’d discovered a new access point for South Mountains State Park and had enjoyed performing an activation there. He wrote,

It is a part of South Mountains State Park custom made for a Thomas Witherspoon visit.  A great site for an activation, video, and photos. If you haven’t been there, please put it on your list!

On Wednesday, November 10, 2021, I packed my Argonaut V and headed to the South Mountains State Park Clear Creek Access.

South Mountains State Park (K-2753)

Max was right–not only was the site easy to find, but it was also absolutely beautiful.

I parked my car at the small entrance parking lot and walked to the one and only picnic table at this site.

The picnic table is under a massive oak tree with huge branches. In terms of POTA, it simply doesn’t get easier than this.

And these trees? I’m guessing they could date back to the Civil War. The trunks are massive. The site itself reminds me of a pasture along one of my favorite footpaths near the house where we used to live in Shere, Surrey (UK). It, too, sported a magnificent oak tree.

Fortunately, no one was using the picnic table under the oak tree, so I set up my station!

The lack of an ATU was no problem, because I paired it with my KM4ACK 40M End-Fed Half Wave resonant antenna.

As for a battery?  Well, unlike almost all of my other field radios, the Argo V is a hungry rig. On receive, it can draw up to 1 amp! This, in contrast to my Discovery TX-500 which draws 1/10 of that. In addition, its voltage range is much less than my other QRP radios, so if a battery’s voltage drops too much, it’ll simply shut down.

Basically, when Ten-Tec made the Argo V it wasn’t with park or summit activations in mind. I’m sure they thought it more of a shack and Field Day radio.

On the flip side, the Argonaut V produces beautiful, rich audio from its internal speaker. That’s what the extra amperage gets you.

I paired the Argo V with my 15 Ah Bioenno 12V LiFePo4 battery and let’s just say the Argo V was very pleased.

On The Air

I started the activation on 40 meters running 5 watts of output power.

I racked up the 10 contacts required to validate the activation within 11 minutes. What a great start!

I was also super pleased to work Max (WG4Z) in a Park-To-Park contact. Very fitting as he was the fellow who told me about this ideal POTA spot!

I racked up another 7 contacts on 40 meters before moving up to 20 meters.

On 20 meters, I worked an additional 7 contacts.

My total time on the air was 31 minutes.

End-Fed Half Wave antennas never disappoint!


Here’s what my 5 watts and the KM4ACK EFHW did that fine day:

Before and after the activation, I took a number of photos–click on the thumbnails to enlarge:

Thank you!

I hope you enjoyed this field report and activation.

thoroughly enjoyed the activation. Not only was it fun taking the Argo V to the field and giving it a good shake out, but it was also such a beautiful day and so peaceful.

Thank you for coming along with me.

A special thanks to those of you who are supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free–I really appreciate the support.

I’ll admit: your generosity made the Argonaut V a reality and I’m most grateful. This radio has been on my wish list for so long and it feels good to have a Ten-Tec rig in the radio family again.

Thank you!
