SoundBytes: Train Talk from Milepost 141

George and Dave are getting ready for Trainfest, and they’relooking forward to a fun weekend with fellow model railroaders! Before theshow, they’re sharing a look at a couple of recent locomotive projects, decoderinstallation tips, and ways to make the most of your setup.Dave walks through his first Blunami installation in anAtlas U36C. Fitting two mini cube speakers required some hands-on work,including carefully cutting away a portion of the locomotive’s weight to makeroom for the speakers. Dave also shares tips from his first experiencesoldering directly to a decoder and discusses swapping the couplers for Kadee#5s.Although Dave installed a Blunami decoder, he hasn’t startedusing the Blunami App yet. Instead, he’s operating the decoder using its Tsunami2 functionality and a command station to build his experience and betterassist customers with their support questions.George also shares a look at his new ScaleTrains SD40-2,where he used a Nix Decoder Buddy and a BLU-21PNEM8 to access the locomotive’s lighting connections, which were otherwise hidden behind the factory-installed proprietary motherboard.Whether you’re planning your next decoder installation orheading to Trainfest, join George and Dave for model railroading projects, practical tips, and a little show prep!Come see us at Trainfest!📍 Baird Center, 400 WWisconsin Ave, Milwaukee, WI 53203📅November 7–8, 2026🕘9:00 AM–4:00 PM both daysWe hope to see you there!Happy Railroading! Related VideosOperations 101: Class Lights (Episode 9): https://www.youtube.com/watch?v=l0i5vqmFYWM

First, an apology! We lost the camera 2 angle and the screen recording of the Blunami app, so there are a few spots where you won’t see all the details you’re used to. Those dang marketing people getting too generous with the delete button!On the bright side, there’s plenty of model railroading goodness to enjoy. Dave brings in an older Atlas Conrail U36C, and George helps him plan some upgrades, added details, and installation of a BLU-PNP8 and LEDs.George also shares the history behind the prototype of his Rapido CF7. He’s already completed a Blunami installation on the model, and the full installation video is in the works. Keep an eye on our YouTube channel so you don’t miss it!To wrap things up, George and Dave dive into CV bit structure and explain how understanding bits can help you better understand how Configuration Variables (CVs) work.Thanks for watching and listening, and happy railroading!#SoundTraxx #SoundBytesFromMilepost141 #ModelRailroading #Blunami #Tsunami2 #ModelTrains #DCC #DecoderInstallation #ConfigurationVariables

In this episode of On Board with SoundTraxx, Dave has ordered his first locomotive and is excited to install a decoder before heading to George’s layout for an operating session!For this week’s model show-off, George shares his Missouri Pacific ExactRail 3737 Bethlehem hoppers. He’s adding weight, coal loads, magnetic air hoses, Tangent trucks, and weathering to create loaded and unloaded trains that can pass each other on the layout. With SoundTraxx Reactive Dynamic Digital Exhaust (DDE), you’ll be able to hear the difference in locomotive workload!Tech Tip: Flex-Mapping & Function DefaultsAre you remapping functions but not getting the results you expected? Dave explains some important things to remember when customizing your decoder’s function mapping:- One function button can control multiple effects.- Moving an effect to a different function button does NOT automatically remove the effect already controlled by that button.- Function outputs do not automatically correspond to function keys. For example, the FX6 function output is not automatically controlled by the F6 button on your throttle. You can configure this using function mapping!- Learn how resetting CVs can help when your decoder isn't behaving as expected.Tune in to learn more about function mapping, decoder customization, and getting the most out of your SoundTraxx decoder!#SoundTraxx #OnBoardWithSoundTraxx #ModelRailroad #ModelTrains #DCC #DecoderInstallation #FlexMapping #ModelRailroading #ReactiveDynamicDigitalExhaust #Tsunami2 #Blunami

In this episode, we welcome our new Support Technician, David Kupratis, to the SoundTraxx team! We’re excited to have him on board and look forward to seeing what he brings to the position.For this week’s model show-off, George brings two MOPACAtlas U30C locomotives that he has upgraded with Blunami and finished up for his coal trains. He also discusses his collection of 45–50 ExactRail Missouri Pacific 3737 hoppers that will be a part of this coal train.Tech Tip: Learn what Dynamic Digital Exhaust (DDE)is and how to quickly set it up using the Blunami App.#SoundTraxx #SoundBytes #Blunami #ModelRailroading#ModelTrains #DCC #DynamicDigitalExhaust #DDE #AtlasTrains #MissouriPacific

George is slacking this week—he hasn’t finished a project toshow off! But he makes up for it with some special guests from the ColoradoRPM.In this episode, George talks with the Colorado RPM teamabout the upcoming show schedule, what you can expect at the event, and why you should come join us. We’re looking forward to seeing everyone and having a great time at this year’s event!#SoundTraxx #SoundBytes #ModelRailroad #ModelRailroading#ModelTrains #ColoradoRPM #RailroadHobby #DCC #ModelRailroadCommunity
