Cabin POTA with the IC-705 and MC-750 at Gorges State Park!

13 Comments

As I mentioned in this previous field report, my buddy Mike and I spent the third weekend of March at Gorges State Park (US-2732) in Sapphire, North Carolina. We had a great weekend of hiking and just hanging out. Of course, I fit in a few activations!

On the morning of Sunday, March 17, 2024, after a nice breakfast and beautiful sunrise, we started packing up. Since we rented a cabin this year, it was an easy process–especially since it was also raining lightly. While I love tent camping, I’m not the biggest fan of packing up a wet tent and gear because later in the day I have to attempt to dry it all out back home.

The cabin also made it very comfortable to do a little Parks on the Air (POTA) until the rain passed and we could start our hike.

I set up my MC-750 vertical next to the cabin.

Inside, assuming I might have more radio frequency interference (QRM) to deal with, I chose my Icom IC-705.

The cabin had a small side table attached to the wall which was the perfect spot to set up my station close to the front door and porch. The weather was very temperate that morning, so I simply left the front door of the cabin open while I operated.

I was correct about the QRM: its pervasive throughout most of the park and is due to arcing on the high-tension power lines that run through the site.

Other than the QRM, Gorges is an amazing park to do POTA.

While I played Parks on the Air, Mike caught up on a book he was reading. Neither of us were pressed for time, so it was a pretty laid-back morning.

QRM Mitigation

After hooking up the IC-705 to the MC-750 and turning it on, the QRM was not only audible–that unmistakable frying sound–but it was clearly visible on the IC-705’s color display.

The noise level was about S5-S6 and persistent.

The IC-705 is a 21st-century radio and I decided to use some of its 21st-century, SDR-powered features in order to improve the audio.

First, I turned on the Noise Blanker (NB). While this feature works best for pulse noises (engine noise and electric fences, in my experience) it also removes a layer of noise from persistent arcing as well.

Next, I also used the IC-705’s built-in DSP (Digital Signal Processing). By turning on the DSP, another layer of noise is removed.

With both NB and DSP engaged, the audio was much more pleasant and less fatiguing.

Keep in mind that even though the noise was minimized in the audio, it was still there in the receiver so this didn’t help much with recovering weak signals under the elevated noise floor. It just made playing radio much more pleasant! Continue reading Cabin POTA with the IC-705 and MC-750 at Gorges State Park! →

Pairing the TR-45L Skinny and the MC-750 at Gorges State Park!

Once a year, I meet up with my friends Monty and Mike for a weekend of camping. We’ve been friends for over 30 years, so it’s always brilliant hanging out with them, hiking, and just enjoying the break in our busy family lives.

This year, we planned our weekend campout for March 15-17, which is slightly earlier in the year than we usually do, but all of us have complicated schedules in April, May, June, and July. So March it was!

We chose to camp at Gorges State Park (US-2732) in Sapphire, North Carolina.

We also decided to opt for one of the park’s five cabins instead of tent camping. The park ranger I spoke with on the phone prior to making the reservation convinced me that we should reserve one of their newly built cabins. The cabins can sleep six, have electricity, and even have heating and air conditioning.

Mid-March in the mountains of western North Carolina is a fickle part of the year. It can be cold, hot, dry, or wet–all easily within one weekend. Choosing a cabin would mean packing in a lot less gear. Done!

Unfortunately, only a few days prior to the camping trip, Monty had to duck out to attend a funeral. We really missed hanging out with him.

Gorges State Park

To my knowledge, I had never been to Gorges State Park. It’s one of the newer parks in the NC system and, frankly, it’s located in a part of WNC that I rarely travel through these days.

The park is vast, and there are a number of trails that lead to waterfalls.

The visitor’s center was built in 2012 and is really impressive. We stopped by there and spoke with staff about some of the hiking options.

I’ve always preferred state and national park camping facilities over private campgrounds. They’re typically well-maintained, and the sites are spaced apart (so I can easily set up an antenna!).

Cabin #5

The camping area at Gorges is one of the nicest I’ve ever seen. It’s all very new. The cabins and shower/bathroom building are only two years old.

The weekend, overall, was warm during the day and cool at night with periods of rain. We both felt pretty happy we’d picked a cabin for the weekend–packing up wet camping gear is never all that fun!

Saturday morning, Mike and I planned to do a bit of hiking, and I wanted to fit in a short activation.

Picnic Shelter Activation

At one of the trailheads for a short hike, we found a spacious picnic shelter. Despite the amazing weather that morning, there was no one else at the shelter.

I scoped out the trees around the perimeter of the shelter, and most were pretty small trees with larger trees behind them. I decided that it would be easier to simply deploy my Chelgence MC-750 vertical.

I brought three radios along on this camping trip: my TR-45L Skinny, Icom IC-705, and Elecraft KH1. I chose the Skinny for this activation! Continue reading Pairing the TR-45L Skinny and the MC-750 at Gorges State Park! →
