Here are photos of my latest build.
A power cable for my Simplex Repeater.
The Surecomm repeater controller has a very wide range of input voltage, 3.6-24V IIRC. Thus you can match it to any battery bank that will be powering your radio.
And a tip for those small magnetic antennas, mostly used for backup purposes.
Get a Neodymium magnet the size of the antenna base, and stack them together. The force will be multiplied.
That is all for today, see you on the next HAMsmithing post!
