Check out the teaser for the new MTR3b V4 “Currahee Version” at https://www.lnrprecision.com #mtr3b #mountaintopper #sota #pota

I picked up the little 3-band Mountain Topper at the Danish #hamradio fair - first test: does it transmit? It sure does 😃 Nice and clean signal, about 4W output with 10V supply.

It’ll be fun to try it out in the wild, I might bring it on a #SOTA mission 🙂

My test setup uses 20dB coupler with another 30dB attenuation added to protect my spectrum analyzer. The load is a 30dB attenuator which can handle 10W, more than enough 👍🏼

More to come! 🙂

It's fairly easy to modify the old version of the MTR3B to replace 30m with 17m. I made a quick after-the-fact video about how to do it. Only requires replacing about 8 or 9 SMD components, removing two turns each from the two LPF torroids for the 30m band and then adjusting the RX side via two pots. https://youtu.be/KoqJe-YhQ9A #LNR #MTR3B #MountainTopper #SOTA #hamradio #amateurradio #qrp #morsecode #K1JDV

I actually got out and did some portable QRP work. Well, until the antenna broke. 🙈🤣

Small radio kit! The Mountain Topper MTR-3B with a BaMaKeY and a Par Endfedz EFT- 10-20-40 Trail Friendly antenna. I use a 3S Lipo 1000 mah battery. They are usually used for rc cars or planes. It's a great setup that I'm eager to try out! And everything fits in a small fanny pack! 🤩👌

Hope to hear you on the bands soon and best 73 de SM2YUW.
