Portable batteries for ham radio

I’m using the following equipment for portable power. All from Hobbyking.

The batteries are stored in my garage in a metal trash can… in case of a battery fire… I hope not this will happen!

M8 Balanced charger

All my DC connectors are XT60 so I can easy switch between fixed power and battery. I can use the M8 charger from my 13.5V fixed power supply or from a car cig lighter adapter.

Recent RS-918SSB HF SDR

My new HF transceiver from May 2020 – Recent RS-918SSB, a SDR based HF transceiver. Much fun for money. A way better RX then my old FT-817ND, built in USB sound card with CAT. Only one cable between laptop and radio!

Much cleaner RX on FT8.

Velleman PSU mod for extra terminals

I have a simple 13.5V PSU from Velleman, works OK and seems it has low RF noise. But it only has one connection terminal, 4 mm banana plugs. I started looking for a terminal connection board but the prices was very high.

So I did a very simple mod, I just drilled two holes in the front panel and mounted two extra 4mm banana plus and connected internal to the same connections points.
