W7L in the 7 Lakes Wilderness Area

5 Comments

Many thanks to Paul (W0RW) who shares the following field report:

Exploring the 7 Lakes Wilderness Area 

It was as a dark and drizzly morning as my XYL (Sharon) and I (Paul)  went up to Cripple Creek, Colorado, and then drove down the Gold Camp Road. The colorful Aspen trees were changing color and even in the drizzle had brilliant yellow and red colors. We proceeded up Fire Road 376 to 11,000 feet, The entrance gate to 7 Lakes. The  South Slope Ranger opened the gate for us and checked our registration. I got out the rain and snow gear and got my poncho on.

(My radio is waterproof).

I don’t normally operate in the rain and snow but this area is available only by pre-registration. The day I picked happened to be a Hurricane remnant day.

The area was just opened to the public this year and there are only 20 cars authorized per day. The area has been closed to the public since 1913–before wireless! This was opening day so I  picked the Special Call Sign, ‘W7L’, to operate with because it is the tri-graph of the name of the area, Wilderness 7 Lakes.

We set out on the trail for Mason Reservoir. As we arrived at the reservoir a snow cloud descended on us accompanied by thunder snow. There were 6 people there already fishing. They said fishing was great, mostly ‘catch and release’. One of the lady fishermen saw the big 10 foot whip on my back pack and asked me if I would like her spot on the lake to fish. I told her I was working ‘catch and release’ on 20 meter CW and I didn’t have a fishing license.

The radio I was using was my 30 pound PRC319 backpack radio which runs 50 watts.

The trail head has a new restroom and a covered picnic table area with one tree nearby for picnic table operations. This is a deep valley (That’s where most reservoirs are kept). So you might need more than 5 watts to get over the hills.

If you have ever taken the COG Railway out of Manitou Springs to the top of Pikes Peak, you have probably seen this area from the “Son of a Gun” Hill.

Warnings: These are high altitude  trails; you must be in good physical condition to hike. Elevations at 7 Lakes range start at 11,000 feet; if you are arriving from a low elevation consider acclimating at 6,000 feet for one or two days.

Bring plenty of water and pace yourself.  Altitude sickness is common. Symptoms can be shortness of breath, nausea, dizziness, headache, dyslexia. Also Loss of clear thought processes like: locking your keys in your car (This happened to one of the fishermen), leaving your log on a rock, forgetting how to program your radio, forgetting your operation time schedule or what the upper band limit of the 17 meter band is.

WG0AT, Steve, was with me on my second trip and he made this cool video:

Then he took a side trip from 7 Lakes and went up the adjoining 12,000 foot, Almagre mountain.  See the history at : http://en.wikipedia.org/wiki/Seven_Lakes,_Colorado

You can reserve your place there by applying at  the Colorado Springs web site:

Wow, Paul! That sounds absolutely brilliant! And taking a PRC-319–? Wow! What a way to add a little extra challenge to your high altitude radio adventure!

Thank you for sharing this, Paul!

The QRPer Board: A new discussion board for QRPer.com

13 Comments

Friends, I’d like to share some good news with you!

The short version:

I’ve created a QRPer discussion board that anyone can join, free of charge, at QRPer.net.

My hope is that this will be a spot for community members to get quick answers to questions and connect with other like-minded operators.

Everyone is welcome and this board is already populated with a number of moderators who will make sure that all questions–no matter how simple–are welcome. Trolls and rude people will be weeded out.

I would encourage you to create an account and check it out: http://qrper.net

The long version:

In the past, I’ve mentioned in posts that email from readers and subscribers (of both QRPer.com and the SWLing Post) has increased to a point that I can no longer keep up with them. It became very evident when I went camping in West Virginia last month and came back home to find no less than 60 messages in my inbox. These 60 messages were all ones needing some sort of reply or acknowledgement–they didn’t include notifications and SPAM.

I take pride in replying to each and every message I receive, but sadly I can no longer keep up with the volume. Sadly, I don’t have enough time especially with my busy family life.

In fact, I realized recently that replying to emails is actually taking a large bite out of the time I have to do content creation. I can’t let that happen, because that could quickly lead to burn-out. Both of my sites are pure labors of love and I enjoy them immensely.

Moody weather and a trailside activation with the amazing Discovery TX-500 and PackTenna EFHW

17 Comments

As I mentioned in a previous post, I’m starting to sort out the gear I’ll take on a long road trip this summer. I still haven’t quite decided which radio will accompany my Elecraft KX2, but the lab599 Discovery TX-500 is on my very short list.

I pulled the TX-500 yesterday to do a firmware update and found my logbook for an activation I made on February 16, 2022. For the life of me, I couldn’t remember writing the field report for that activation.

I checked my YouTube channel and, sure enough, buried at the bottom of my video list was the activation video marked as “unlisted.”

That bit of time between mid-February and mid-March was crazy for me. I was in isolation for a week (thanks Covid) and had a very hectic family schedule. I accumulated a small backlog of videos then and this one was lost simply lost in the shuffle.

Here’s the report and video from that activation:

Clear Creek Trail

It was Wednesday, February 16, 2022, and I was driving to my parents’ house to help them with a few projects. I had enough time to make a little detour to the Clear Creek Access of South Mountains State Park (K02753) and had two things in mind: a good hike and trailside activation.

The weather? Man oh man was it was fickle.

On the interstate, I got caught in a proper downpour and traffic slowed to a crawl.

I thought about throwing in the towel then, but I made a promise to myself that I would continue driving to the park if it wasn’t raining when I approached the park exit on the interstate.

You know what? The rain stopped maybe 3 miles before the exit. So I continued my drive. Continue reading Moody weather and a trailside activation with the amazing Discovery TX-500 and PackTenna EFHW →

The Canadian Basic Exam

32 Comments

As I mentioned in a previous post, I’ll be spending a few weeks in Canada this summer and will certainly play radio.

I’ve decided to bite the bullet and study to hopefully pass my Basic license exam while there.

I say “hopefully” because my timing couldn’t be worse.

I started studying about 2 weeks ago in earnest–allowing myself one month of prep before my trip–but frankly, I’ve been so busy I’ve had almost no time to dedicate to  studying. In fact, a good 5 days of my two weeks were taken up with a POTA camping trip in WV.

Why in the world do I do this to myself?

That’s what I keep asking.  🙂

There’s no logic in getting a Canadian license because as a US license holder, I can simply add /VE2 onto my call while in Québec et voilá I’m legally on the air!

That and, here at home, I’m juggling numerous projects before we leave, so study sessions are crammed into short openings and are sporadic. Not how I like to study for something like this.

Thing is, I want to fit in the bulk of my studies within the next two weeks so that as soon as I’m on Canadian soil, I can go ahead and schedule a remote exam (one must be in Canada to take the exam even if via Zoom). I don’t want to spend my whole vacation studying, so I’d like to knock this out very early on.

So why get a Canadian license?

In the past, our family has spent whole summers in Canada primarily in Prince Edward Island and Québec. We know there’ll be many more of these trips in the future and my wife and I even entertain the idea of spending nearly half the year in Canada once we’re empty nesters.

I feel like it would be beneficial to have an actual Canadian call for those extended trips; especially in PEI where it’s so easy to grab DX almost anytime I hop on the air.

In fact, my callsign–should I pass–will have a VY2 prefix because that’s where our mailing address is.

There’s another reason, if I’m being honest with myself: I like the challenge of trying to pass the test. It’s just…my timing is kind of [understatement]  crappy. Continue reading The Canadian Basic Exam →

Matt’s “Ultra-Lyte” Hydration Vest QRP Field Kit

8 Comments

Many thanks to Matt (W7MDN) who writes:

When I was first getting into Ham radio a couple years ago, I ran across a slide presentation done by Fred KT5X on “Ultra-lyte” QRP. In it, Fred has pictures of a trail running hydration vest that contains a complete SOTA station, water, snacks and a jacket. I was sold on the idea, and made it my goal to start making my own ultralight setup.

Click here to download KT5X’s original presentation (PDF).

As time went on, I really got into the ultralight approach to SOTA, taking every opportunity to reduce weight and shrink my pack down. I enjoy some trail running, mountain biking and combining SOTA/POTA with either is the ultimate combo of adventure and ham radio. Continue reading Matt’s “Ultra-Lyte” Hydration Vest QRP Field Kit →

Choosing the right QRP radios for an extended road trip

69 Comments

As I mentioned in a previous post, if all goes according to plan (and we never take that for granted anymore) our family is plotting an extended road trip into Canada this summer. We’ve got most things lined up: a brilliant house sitter, an  home base in Québec, a doggy “summer camp” for Hazel (my kind father-in-law), and, oh yes, a list of parks and summits I hope to activate.

What I’m still sorting out is the radio gear.

Let me be the first to admit that I’m blessed with a number of field radios (so be warned: this is going to sound very much like a first world problem) and there are aspects of each one that I appreciate. On a road trip like this, though, space will be at a premium.  I can really only justify two compact HF radios and their associated accessories. I plan to bring at least one of my Bioenno 3Ah 12V batteries and charger as well.

Fortunately, I can take a few antennas. We have a roof top Thule cargo box that is actually perfect for my CHA MPAS 2.0, MPAS Lite, and TDL–they’ll fit on the floor of the box and essentially take up no room in it. Otherwise, the cargo box will be dedicated to all of our bulky camping gear.

My HF radios will have to fit in the car trunk/boot along with food, clothes and other supplies.

I already made a decision about one of the radios that will come with me. In fact, it was a bit of a no-brainer:

The Elecraft KX2

I’ve taken the KX2 on all of my major road trips since 2016. It’s incredibly compact, feature-rich, and can handle any situation I throw at it.

In fact, as with two previous years in Québec, I’ll use it to do a little shortwave radio listening (always an important aspect of my travels) and record the BBC Midwinter Broadcast to Antarctica.

Indeed, recording this particular broadcast has become an annual event over at the SWLing Post. It’s one of the highlights of my summer and always falls on my birthday.

The other thing about the KX2 is since it has an internal ATU, I can pair it with any antenna: resonant or not. If the need arises, I can also build an antenna from speaker wire, computer/phone cable, or pretty much anything that conducts.

And, of course, if I pair the KX2 with my low-profile AX1 antenna, I can operate anywhere. I do have a number of urban parks in Ottawa and Québec City that I plan to operate super low-profile and on foot.

The KX2 batteries require that I bring the rapid battery charger and that does take up a little more space (almost the same amount of space as the radio itself!).

As for a second radio…

I think I can get away with packing one more radio. That way, in the unlikely even I have an issue with the KX2, I would have a backup. Plus…hey…variety, right?

I don’t have the room to take my Mission RGO One, Icom IC-703 Plus, or Ten-Tec Argonaut.

I’ve even excluded the KX3 from the list because it wouldn’t offer me much more than the KX2 (just 160 & 6 meters, plus a little extra power output if needed it). The radio I choose needs to be one of my more compact, lightweight, and efficient models.

I’ve also left out the QCX-Mini because I want more than a mono band radio.

Hmmm…then again, the QCX-Mini is so extremely small, I could throw it in my glove compartment and no one would be the wiser [shhhh…let’s keep this between us, shall we?].

Here’s a quick run-down of some of the radios I’m considering and why: Continue reading Choosing the right QRP radios for an extended road trip →

Leo’s first SOTA activation included impressive SSB QRP DX and a CW pile-up!

Many thanks to Leo (DL2COM) who writes:

Hey Thomas,

[…]I just wanted to give you a quick update on my 1st SOTA activation (May 18th). We spent a few days in the south of France with the extended family. From the garden of the house we rented we were constantly looking towards a beautiful mountain front and it turned out to be SOTA summit FR/CR-205 (726m, 2382ft). So I decided to try and activate it since we had enough people around who offered to watch out for our kids.

Next morning: 6am my dear XYL and I started our ascent.

What a wonderful scenery with morning mist covering most of the mountain landscape and the sun in perfect shape for an early hike.

At around 7:45am we arrived at the summit and I started throwing up my arborist weight into pretty much the only suitable tree available. Continue reading Leo’s first SOTA activation included impressive SSB QRP DX and a CW pile-up! →

Xiegu G106 preliminary specifications and features

13 Comments

Xiegu distributor, Radioddity, has now publicly announced a product page for the new Xiegu G106.

No pricing/availability mentioned, but we do learn a few more details from their page.

Features:

  • The Xiegu G106 is a 5W SDR transceiver using 16bit-CODEC sampling
  • SSB, CW, AM modes are supported along with wide FM reception (for the FM broadcast band)
  • General coverage receiver
  • Three selectable CW bandwidths
  • Digital modes when connected to a computer with the Xiegu DE-19 interface

Specifications

  • Receiver frequency range: 0.55~30MHz and 88~108MHz (WFM)
  • Transmitting frequency:
    • 3.5~3.9MHz
    • 7.0~7.2MHz [I assume this is incorrect]
    • 10.1~10.15MHz
    • 14.0~14.35MHz
    • 18.068~18.168MHz
    • 21.0~21.45MHz
    • 24.89~24.99MHz
    • 28.0~29.7MHz
  • Receiver sensitivity:
    • CW: 0.25uV @10dB S/N
    • SSB: 0.5uV @10dB S/N

  • Operating voltage: 9~15V DC
  • Standby current: 0.37A @Max
  • Transmitting current: 2.8A @Max
  • Dimensions: 120*40*135 (mm)
  • Weight: about 720g (only host)

Radioddity notes: “The shoulder strap [above] is for display only. Final equipped accessories not decided yet.”

My G106 takeaways?

Based on Xiegu’s previous offerings, I would have to assume the G106 could be in production within a few months (supply chains/C-19 pending). It’ll likely be released with basic firmware and updated with time. It’ll be price competitive for sure.

I would hope that perhaps they’ve worked on the audio characteristics and noise floor of the G106. Previous Xiegu products have mediocre audio characteristics and a higher noise floor than my other transceivers. Let’s also hope the front end is more robust than the X6100.

At 0.37 Amps, current drain in standby/receive is a tad on the high side for late model QRP portable radios. Still, quite respectable for a field radio.

It doesn’t appear the G106 has an internal tuner, nor an internal battery unless they’ve simply omitted this from the features list.

It also doesn’t mention CW and/or voice message memory keying which I consider to be so valuable for park and summit activators. If history is an indicator, I suppose they could add this later in firmware updates.

Also, the Radioddity announcement mentions that the G106 covers “[t]ransmission and reception of all amateur frequency bands within 3.8~29.7MHz.” Yet in the specifications, they fail to list the 60M band and the 40M band is noted as 7-7.2 MHz. I assume the 40M band range is simply a typo–I can’t imagine it would actually stop at 7.2 MHz. I also imagine they may have simply omitted the 60M band channels. RX seems to dip as low as 0.5 MHz, thus covering most of the mediumwave broadcast band.

Truth is, these are early days for the G106 and we may learn that it has more features than listed here on Radioddity’s page.

If it does indeed lack an internal ATU and/or internal battery, I assume the price point would be well below that of the X5105 and X6100; my (complete and total) guess would be somewhere between $300-400 US.

I’ll post more info about the G106 as we learn more. I’ll also try to update and correct this post if I learned some of these details are incorrect.

SOTA in the Clouds: Pairing the Elecraft KX2 and MPAS Lite for brilliant QRP fun on Craggy Dome!

6 Comments

Although I live in the mountains of North Carolina and am surrounded by SOTA summits, it’s much easier for me to activate a park rather than a summit.

Parks can be quite easy: find the park on a map, drive through their main entrance, find a good picnic table to set up, and next thing you know you’re on the air! Of course, wildlife management areas and game lands can be more tricky, but typically you can drive to the activation site.

Summits–speaking as someone who activates in North Carolina–take much more planning. If it’s a new-to-me summit, I typically need to:

  1. find the GPS coordinates of the true summit
  2. map out the drive to the trail head
  3. read through previous activation notes (if they exist) to find out
    • what type of antenna/gear I might pack
    • and any notes I might need to find the trail or bushwhack to the true summit (quite often published, well-worn trails don’t lead to the actual summit)
  4. look up the trail map and make sure I have a paper and/or electronic copy
  5. pack all needed gear for the hike, activation, and emergencies
  6. sort out the time it will take to travel to the site, hike the full trail to the summit, activate, and return home

If you ask most any SOTA activator, they’ll tell you that the planning is part of the fun.

It really is.

One summit I’ve had on my activation list for ages is Craggy Dome (W4C/CM-007). Out of the higher summits in this region, it’s one of the easier ones for me to reach from the QTH. In fact, as with Lane Pinnacle, I could simply hike from my house directly to the summit (although one way to Craggy might take the better part of a day). The trailhead is about a 50 minute drive, and the hike about 30 minutes.

SOTA notes and All Trails indicated that Craggy Dome’s trail isn’t always easy to follow and that it’s steep and slippery.

Craggy has been activated loads of times, though, so I wasn’t concerned at all.

Living here and knowing how much brush there was on the manway to the summit, I knew that Craggy would be a pretty easy summit if I could activate it after the parkway re-opened for the spring and before the mountain “greened-up”; about a five week window.

Meeting Bruce

My schedule opened up for an activation of Craggy Dome on the morning of April 21, 2022 and I was very much looking forward to it.

I wouldn’t be alone on this hike either. Bruce (KO4ZRN), a newly-minted ham, contacted me and asked if he could join me on a hike and simply be an observer during a SOTA activation.

Fortunately, timing worked for him to join me on this particular SOTA activation. Continue reading SOTA in the Clouds: Pairing the Elecraft KX2 and MPAS Lite for brilliant QRP fun on Craggy Dome! →

Xiegu X6100: Greg uses an OTG mouse for better selection control

8 Comments

Many thanks to Greg who writes:

After seeing your YouTube channel, I decided to try my hand at POTA operations. There are at least three state parks on the POTA list nearby. I am trying to increase my CW speed, because CW would be a bit more efficient for operations.

[…]I have gotten an Xiegu X6100. The biggest reason was it is Linux based, which I am familiar. It is a nice size also has nice features. With an external battery (car jump starter) and a decent antenna, it should be able to make contacts.

My unit has the version 1.1.5 soft/firmware. I have found the Bluetooth and WIFI connectivity be lacking a few software components. I have been able to make Bluetooth connections to a keyboard and speaker, one at a time. However, there is no data connection to the just of the software.

So, one hears no sound and pressing a key generates no data. The X6100 has the potential to be a very capable modern transceiver. I got it through Radioddity.

I have working with the support group, who are good. Hopefully, the next software update will improve things.

What I found that worked and was a help was a mouse/trackball with OTG (on the go) cable connected to the USB Host port.

One was able to select the menu/submenu items.

The best improvement was Memory Editing the submenu Tag item. Using a trackball to update the Tag information via the popup screen keyboard was very easy and quick. Using a mouse/trackball with X6100 might be a good video.

Thank you for the tip, Greg! I will have to give this a go. I’m curious if other readers have explored using a mouse/trackball with the X6100 as well. 

One of the most appealing things about the Elecraft K4 interface (another Linux-based transceiver, I believe) is that you can connect a mouse and have full control of the radio. This made selecting items so much easier than using a finger to do the same on the touch screen.
