New video out on YouTube. Topic is QRP!
QRP is efficient, portable, & powerful, but sometimes, condx demand more. In this vid, I show how a compact HF amp helped complete a failed Winlink session—without ditching my low-power strategy.

Now that the Yaesu FTX-1 is out, this might be a good time to take a look at how data comms work with the Icom IC-705 and a Microsoft Surface Go tablet.
With the IC-705, the wires are optional!

QRP WinLink session using the ICOM IC705, Microsoft Surface, and N9SAB OCF dipole set up for NVIS.
There's very little talk in this video. The idea is simply showing newcomers what's possible with low power.

Hello Operators.
In this video we go through charging our Microsoft Surface or similar laptops and tablets off-grid, using the same 12 volt batteries that power our ham radio gear.

MESHTASTIC Traceroute
Messages from weak stations get pushed further by more capable stations (or any station actually). You can see the path from your station to another using the meshtastic traceroute feature.

Not an HF replacement, but it's certainly another tool in the toolbox.
We have ~5 nodes set up on 433Mhz in Oulu, Herukka area (KP25QC, KP25QB). Later on, we'll add 868Mhz (913Mhz USA). If you have the gear, pls help us test.

Setting up a high contrast theme saves current and also saves your eyes. Here, I'm running 2x laptops, 705, SDR & charging a DMR handheld. Current draw, 0.83A I can also walk outside in the dark without being night blind.
Food for thought!

Although #hamradio can be fun, it isn't my hobby! For me, ham radio is a tool. Think of it as an axe or long rifle.

Easy tutorial today. This time, we're learning how to connect two 12-volt batteries in parallel. We do this to increase the capacity of our solar storage, using two identical batteries.
