You’ll certainly need some MATERIALS:
– T37-2 Toroids (my usual): https://amzn.to/3hFsYlj
– T50-2 Toroids (a little more efficient and maybe easier to build): https://amzn.to/2QCkGio
– 28 ga Magnet Wire: https://amzn.to/3b9Isf4
– 39pF 100v Ceramic Capacitor (0603 case recommended): https://www.digikey.com/product-detail/en/kemet/C0603C390J1GACAUTO/399-15862-1-ND/7516362
– 62pF 100v Ceramic Capacitor (0603 case recommended): https://www.digikey.com/product-detail/en/kemet/C0603C620J1GAC7867/399-14992-1-ND/7382541
NOTE: Consider a few other capacitors in the 22pF – 100pF range, depending on the traps you’d like to build.
– Perforated Prototype Board: https://amzn.to/2YLsFOJ
– 5/8″ Heat Shrink Tubing: https://amzn.to/3lwwGjt
– 1/4″ Heat Shrink Tubing: https://amzn.to/2G9bGzk
And you’ll need some TOOLS:
– Dremel (or similar)high-speed rotary tool: https://amzn.to/3gFEkEL
NOTE: I have had my Dremel tool for about 25 years now and it hasn’t missed a beat. Based on my personal experience, I would recommend going with the name brand tool.
– Diamond Cutting Wheels: https://amzn.to/2QBRHve
NOTE: I really like these because you can’t cut yourself with them, but they cut the perf board and BNC connector brass just fine.
– Soldering Iron (any will do) with a fine tip: https://amzn.to/2GaENlN
NOTE: I’ve been using this one for about a year with no issues. The heat gun is AWESOME for hot air/solder paste construction. The iron works well for traditional soldering.

Please share your builds with me when you’re done, and tell us about how it works out for you in the comments below.
Here’s a tangle-free way to wind up your antenna wires without a line winder or any extra weight. I call it the “Goat Wind” because I learned it from a WG0AT video. The man is a SOTA legend and has produced some great videos – check out his channel (https://www.youtube.com/user/goathiker) if you haven’t.
For the record, it’s pronounced “wīnd,” not “wind” ????… silly English words.
Anyway, try this out and let me know how it works for you. Sure, you’ll still occasionally get a tangle, but by not twisting the wire, it’ll unfurl without issue the majority of the time.
Four new padded cases arrived and are ready for an unboxing and fit check. Will any of these be a perfect match for the LNR Precision Mountain Topper MTR3B? Let’s find out…
The last case – an Amazon Basics portable hard drive case – is just about perfect. But the other cases have their niches too. Check out the video to see how I’m putting them to use.
#1: GLCON Case ($5.99) https://amzn.to/3g3nIqb
Perfect fit for these smaller mint tins https://amzn.to/3aCBcrN which will fit a standard Pixie transceiver board with minor trimming. Too small for MTR3B or full-size Altoids tins.
#2: ProCase Travel Case for Crucial X8 drive ($9.99) https://amzn.to/3g7gBgm
Perfect fit for Altoids mint tin radios with connectors and buttons on the skinny ends only. This one worked out perfect for my Forty-Niner and Chinese Super Rockmite (not shown in video). Too small for MTR3B.
#3: ProCase for Samsung T5 ($8.99) https://amzn.to/3kRENaf
Odd molded padding in bottom of case does not fit any mint tins or the MTR3B, but an Altoids Tin, even with connectors on the longer sides, fits well in the case. The molded bottom part could likely be used to store a small key, battery, or smaller earbuds. The least successful fit of the cases purchased, but still useful.
#4: Amazon Basics My Passport Essential Case ($6.71) https://amzn.to/3g3pbwH
Excellent fit for the MTR3B, a small iambic paddle, battery, and antenna. Great option for a compact MTR3B case!
Each year, our SAR team, San Diego Mountain Rescue, completes “Mountain Climb” trainings where we work on our teamwork and summer mountaineering skills. This year, a permit spot opened up on a trip for Middle Palisade (14,012′), one of California’s 14ers. Here’s the video trip report.
My pack for this trip was a 17L, 15 lb load – one of the lightest packs I’ve carried for a 2 night trip. Here’s the inventory.
Pack Inventory – Big 4:
– CAMP Skin Pack – https://skimo.co/camp-skin-pack
– Marmot Alpinist Bivy – (Discontinued. Check out OR Helium Bivy instead https://www.rei.com/product/151751/outdoor-research-helium-bivy)
– Mountain Hardwear Mountain Speed 32 – (Discontinued)
– Reflectix Pad – https://amzn.to/3fbCsmn
HF 80-10m, SSB, CW, and some Digital modes, in a sub 2lb kit? Yup…
The Elecraft KX2 is an incredibly capable rig with an internal battery, built-in ATU, and excellent power efficiency in a very small package. Combine that with a custom ultralight antenna, mini key and microphone, and a compact case, and you’ve got one of the smallest go kits you’ll ever find.
The KX2 does PSK and RTTY intrinsically, but if WSJT modes are a priority for you, add a Raspberry Pi. Check out KM4ACK’s channel for more info on Pi builds for ham radio. https://www.youtube.com/user/jasonoleham
Case – Kelty Cache Box (small): https://amzn.to/3hn1OPT
* Note – some stretching may be required for an easy fit.
Antenna – K6ARK Ultimate 9:1 End Fed Random Wire: https://youtu.be/kSQzUETRMlk
Mini Mic – Modified from one of these: https://amzn.to/2DQIYSv
* Build video coming soon.
Mini Key – Homebrew, but there are some nice commercial options…
– AME Ultra Portapaddle: http://americanmorse.com/ultraportapaddle.htm
– Know of another, perhaps 3D printed option? Share in the comments!
