Dave (NM0S) has updated the NorCal 40A transceiver kit. Here’s the information from NM0S’s website:
NM0S Electronics has received permission from the Wayne Burdick N6KR to produce an updated version of the legendary NorCal 40A CW Transceiver.
The new ‘B’ version kit overcomes the issues with obsolete components that caused the original kit to end production.
The NorCal 40B follows the design of the original faithfully, while adding a rugged pre-drilled, silkscreened enclosure!
On Friday, November 3, 2023, I had planned to activate Mount Mitchell–the highest summit in eastern North America. I need to activate Mitchell soon because I’ve yet to activate it for SOTA in 2023 and when winter weather sets in (quite early at that altitude) the park is inaccessible.
Unfortunately, last week, the National Park Service closed an 8 mile portion of the Blue Ridge Parkway due to (no kidding) park visitors feeding and trying to hold bears at the Lane Pinnacle Overlook.
I won’t get on my soapbox about how people are so out of touch with nature that they feel human interaction with bears is a good thing. It breaks my heart because as we natives of WNC say, “a fed bear is a dead bear.” Bears that become comfortable with humans become (at best) a nuisance and (at worst) aggressive. This is bad for people and it’s bad for our bears who are otherwise shy and avoid humans.
Okay, I said I wouldn’t soapbox about this…
That 8 mile section being closed meant that what would have been a 50 minute drive to the summit of Mitchell turned into a 90 minute drive. Round trip, I simply couldn’t fit that in my day, so I made alternate plans.
Another summit on my list to activate before year’s end was Richland Balsam.
Richland Balsam is actually the highest summit on the Blue Ridge Parkway and is, in fact, at one of my favorite points along the parkway.
That Friday morning, I dropped my daughters off at their classes and drove an hour or so to the Haywood-Jackson Overlook.
In the valley, as I started my drive to the parkway, past the Cradle of Forestry, it was 30F/-1C. I was concerned that on the summit–nearly 4,000′ higher in elevation–that the temp would be closer to 20F. Fortunately for me, as I gained elevation, the temperature climbed too. We were having inversion that day so the higher altitudes were actually warmer than lower altitudes. This is not uncommon in the fall and was very welcome that particular Friday morning!
Only three weeks earlier, there would have been no free parking spots at the Haywood-Jackson Overlook overlook–it would have been packed.
Fortunately for me, all of the leaf-lookers had gone and I literally had the place to myself. What a luxury!
And the temperature? A balmy 43F/6C.
The hike to Richland Balsam is one of the easiest along the parkway.
At the north side of the parking area, you’ll see a trailhead for the Richland Balsam Nature Loop Trail.
The trail isn’t long; I believe the entire loop is just shy of 1.5 miles.
Although I didn’t set out to do this, I ended up making a video of the entire loop trail hike along with the activation (of course, you can skip over those parts in my activation video below).
Sadly, one thing you won’t be able to enjoy in my video? The smell. The air is filled with the fragrance of balsam trees along the entire trail–it’s just amazing!
The summit of Richland Balsam is at 6,410 feet ASL (1,954 meters).
The summit is covered in trees which is brilliant for SOTA activators. Another luxury is that there are two benches within the activation zone. I did pack my Helinox Zero chair as a backup, but didn’t need it.
Setting up my KH1 for a SOTA activation couldn’t be easier or faster. I show the whole process in my video at a very casual pace. Continue reading My first SOTA activation with the new Elecraft KH1 handheld QRP transceiver!
Yesterday morning, I took my Elecraft KH1 to the summit of Richland Balsam and performed a SOTA activation using only the KH1’s whip antenna on 20 meters (I ran out of time to hit 17 and 15M).
It was insane fun. Without really intending to, I actually filmed the entire hike to the summit, entire activation, and the hike back to the car. I’m not sure I’ve ever done that before. I plan to post the video by Monday (Nov 6) if at all possible (again, trying to push my KH1 videos to the front of the line for a little while).
After the SOTA activation, I drove back to town to pick my daughters up at their acting class. I arrived about 20 minutes before the class ended and thought, “why not pull out the KH1 and see if I can hunt some POTA activators–?”
I opened the trunk of the car, grabbed the KH1 from my SOTA pack and then decided to even film this short, impromptu hunting session.
As you’ll see in the video below, it took no time at all to deploy the KH1, hop on the air and work a couple of stations.
Click here to view on YouTube.
I could have also chased some SOTA activators, some DX, or just looked for a random ragchew with someone calling CQ.
I like hunting/chasing POTA and SOTA activators, though, because the time commitment is manageable. For example, by the time I ended this video, my daughters and one of their friends were already hopping in the car to hit the road. I didn’t have to apologize to anyone for ending a QSO early. 🙂
I decided that I’m only going to use the KH1 both in the field and in the shack during the month of November. The only exceptions will be other radios I need to test or if I need to make contacts outside of the 40-15 meter KH1 window.
One of the big reasons for this level of commitment is that I am in the testing group of the KH1. This is how we flesh-out any minor issues that may have gone unnoticed.
Another reason is I do plan to post a comprehensive review of the KH1 eventually and I only feel comfortable doing this after I’ve spent dozens of hours with a radio.
If I’m being honest, another reason is that I absolutely love this anytime, anywhere radio. It’s so insanely portable, I take it with me everywhere. The KH1 and I have been inseparable since last Monday when I took delivery. And, yes, I’m still contemplating what her name will be.
Note that I will post some of my other activations videos this month (I’ve quite a few out there!) and I will also post the occasional bonus video exclusively on Patreon. Indeed, I posted a video on Patreon yesterday where I paired the CHA F-Loop 2.0 with my Icom IC-705.
Stay tuned for more radio goodness and I hope everyone has an amazing weekend!

Yesterday, I posted some initial notes about the Elecraft KH1 and mentioned that I hoped to perform a POTA activation later in the day.
I’m pleased to report that I was able to fit in that activation!
I’m pushing this report and video to the front of the line because so many readers are eager to see how the KH1 performs during a field activation. Instead of focusing on the park, in this field report we’ll be taking a closer look at the KH1 and my initial impressions after performing a pedestrian mobile POTA activation with it.
I had a very hectic schedule yesterday and was on the road in/around Asheville from 8:00AM to 2:00PM before an opportunity opened to fit in an activation.
After a quick trip back to the QTH for lunch, I packed the Elecraft KH1 field kit in my EDC pack (a travel laptop bag).
Herein lies my first impression of the KH1: even though I knew I had packed the entire kit, I felt like I must have been leaving something behind.
Sounds funny, but even though I pride myself on making fully self-contained field radio kits, I felt like there must have be something else I needed. The KH1 field kit just seemed too small, too lightweight, and too compact to have included everything I needed for an activation.
Intellectually, I knew that it included everything needed, but I still did a mental inventory:
Hard to believe, but it was all there.
Trust me: the first time you take your KH1 to the field, I bet you’ll feel the same way I did.
Because I was so short on time, I decided to activate the Blue Ridge Parkway which is the most convenient POTA entity when I travel into Asheville from Swannanoa.
It was cold and blustery afternoon the afternoon of November 1, 2023. At my QTH, I checked the temperature and it was about 34F. I knew it would be a bit warmer in town which is a good 1,000 feet lower in elevation, but I still grabbed my gloves on the way out the door. Glad I did!
As I mention in the activation video below, I wasn’t exactly on my “A Game.” I had received a couple of vaccines the previous day and my body was a bit achy as if I was starting to get the flu. But, of course, I wasn’t. Still… I didn’t feel 100%.
I arrived on site and set up couldn’t have been easier:
We’re talking a 30 second process even for someone who moves slowly.
Keep in mind the following notes that are relevant at time of posting this field report (November 2, 2023):
I consider the Elecraft KH1 speaker to be a “bonus” feature. The speaker is small (1.1 x 0.65”) and limited in fidelity.
I had planned to connect my Zoom digital recorder to the KH1 and record audio directly from the headphone port during this activation. Continue reading My First POTA Activation with the New Elecraft KH1 Handheld QRP Transceiver!
I’ve had the Elecraft KH1 in my hands now for a little over 24 hours. I had hoped to squeeze in a POTA activation yesterday, but the stars did not align. I had way too many dad responsibilities on Halloween.
I hope to correct that today with a POTA activation, if I can squeeze it into a hectic afternoon. It’ll be a cold, blustery one for sure!
Yesterday, I did fit in a couple of opportunistic contacts with the KH1 along with some morning on-the-air time in the home office while working on projects.
Since I’ve gotten so many questions about the KH1 since Monday, I thought I’d share a few random answers and notes here.
Quite a few of you have written in to ask how well the KH1 works on a desktop. Some have mentioned that they like the size of the KH1, but don’t see themselves doing the pedestrian portable thing.
The answer is, the KH1 works really well as a small desktop transceiver.
In fact, yesterday morning, if I made contact with you, it was with the KH1 on my desktop while I was plugging away on spreadsheets in the office.
Elecraft designers cleverly positioned the AF Gain and Encoder knobs so that they’re accessible when the radio is lying flat on its back.
As you can see in the photo above, the key plug is positioned between the two knobs, but there’s enough separation there that you don’t feel your key cable is in the way while making adjustments. Of course, the rest of the controls are on the top, so they’re very accessible.
To be clear, I prefer using my KX2 or KX3 on a desktop (they were designed for this), but I feel the KH1 works quite well.
In fact, for the average 30-60 minute park activation where I’m connected to a wire antenna? I see myself using the KH1 on a tabletop. I’ll operate pedestrian portable when doing SOTA and fitting in those little opportunistic and impromptu radio sessions.
The ergonomics of the KH1 are excellent. It was designed to fit in the palm of your hand, and it does this perfectly. Continue reading Update: Some Elecraft KH1 Initial Notes
I was speaking with my buddy Joshua (N5FY) in mid September. He’d recently acquired an Elecraft KX1 and the topic came up about pairing the KX1 with the AX1 antenna. I realized that in all of my experimenting with the AX1, I’d never paired those two. What!?!
Time to fix that!
On Thursday, September 28, 2023, I had a nice midday window to play radio. After dropping my daughters off at their classes, I stopped by the French Broad Food Co-op and grabbed a container of their chicken noodle soup from the refrigerator section.
I then made my way up the Blue Ridge Parkway (K-3378) to the Craggy Gardens Picnic Area at Bearpin Gap–one of my favorite spots on the BRP.
Despite stunning weather and the beginnings of fall foliage, the parking lot was pretty empty. After all, it was a Thursday and a good week or two before leaf-lookers descend upon western North Carolina.
I pretty much had the picnic area to myself (there was one other person there). I picked a picnic table at the top of the hill under the trees.
When my wife and I lived and worked in Munich, the salutation I learned before any other was “Mahlzeit!” At Siemens, I remember walking through the hallways and people I’d never met before exclaimed “Mahlzeit!” as I passed by.
I quickly learned that Mahlzeit essentially meant “Lunch Time!” and I still say it today to my family when I’m about to make or grab some lunch. Funny how these things stick with you.
Now where was I–? Oh yes…
First thing I did at Craggy was set up my stove to start heating the soup. I show this in my activation video below.
If interested, here are the components of my stove kit:
Next, it dawned on me that I would need to attach the AX1 counterpoise to the KX1. I didn’t bring one of my copper clamps to attach to the outside of the AX1’s BNC connector, so I needed to find another grounding point on the KX1.
I then remembered that the KX1 has two thumb screws on the bottom of the radio. Knowing Elecraft, I assumed that these screws could be used as an attachment point for a counterpoise, but I wanted to confirm that the screw itself had a direct connection to ground.
Fortunately, I keep a small multimeter in my supplemental gear bag in my car. It’s an inexpensive Allosun Pocket Multimeter. I use it for things like this: testing.
I set the multimeter to read continuity and then placed one probe on the outside of the KX1’s female BNC and the other on one of the thumb screws. Sure enough, there was a direct connection to ground. I didn’t need to worry about the KX1 chassis paint insulating the connection to ground because the thumb screw had a direct connection. Perfect!

Thomas,
Like you, I have a number of QRP radios with differing deployments. Some go in the trunk of the car, others go in my shirt pocket.
Here is a fully featured QCX-Mini station in a Tupperware container.
While I believe QRP operation and non resonant antennas should be mutually exclusive, I have the Elecraft T1 as an option. Also when I burn a hole in the sky going QRO, the TalentCell gives me full 5 watts. If needed they both fit in the antenna sack. The 9 volt rechargeable is for normal use.
Earbuds, key and EFHW and I am QRV.

Lately, I’ve been kitting out another fully self-contained field radio kit that would be small enough to fit in my EDC (everyday carry) laptop bag–something super compact.
I’ve been getting some great ideas from those of you who have added your kits to the Field Radio Kit Gallery.
[By the way, if you’ve submitted your kit to the gallery and haven’t seen it yet, note that I’m posting these in the order received and there are many in the pipeline!]
I’ll likely build my EDC field kit around the Elecraft KX1 or the Mountain Topper MTR-3B, then pair it with a good wire antenna.
But this process got me thinking: if money was no object, and I wanted the most compact and versatile multi-band field kit, what radio and antenna system would I choose?
My answer? A kit built around the Elecraft KX2 and AX1 antenna.
In my experience, the KX2 AX1 combo is hard to beat. It’s compact, effective, low-profile, and you can set it up pretty much anywhere.
Let’s explore my reasoning here keeping in mind–in my world–this is a very deep rabbit hole to go down. I’ll do my best–no promises–to keep this as concise as possible:
Here are all of the components of my typical KX2 AX1 field kit:
This is all that is needed for a field activation.
And if you’re an SSB operator? You don’t really need a microphone because one is built into the KX2 (that said, I’d suggest you build a compact mic if you plan to do a lot of SSB operating).
If I wanted to make this kit even a bit more versatile? I’d add a kneeboard to the list. This gives one the ability to operate without a picnic table.
I recently published a video showing how the KX1 and AX1 can fit on a kneeboard.
What makes this field kit so portable is that the KX2 is one of the most compact general coverage HF transceivers on the market.
It’s certainly the most compact (at time of posting) when you realize that two important components–the battery and ATU–are internal options.
The AX1 antenna is also incredibly compact–it comes apart in such a way that no one component is longer than about 6 inches. What you see in the photo above is the entire radio and antenna system.
Sure–and let’s get this out of the way right up-front–the AX1 is a compromised antenna, and being a massive fan of simple wire antennas myself, I know a properly deployed wire in a tree is going to provide better gain each and every time.
Also, people who live in more remote parts of the world–say, Hawaii, the Yukon, or Perth, Australia–where the amateur radio density is sparse within their propagation footprint, the AX1 will not be as productive as it is for me here in the eastern half of North America.
