Arduino SWR Power Meter Final Parts & Calibration

Posted on July 24, 2015July 24, 2015 The Engineer

Now the final bits have arrived for the SWR Meter module, I can do the final assembly. Here the SMA connectors are installed on the side of the eBay meter, for forward & reverse power tap. These are simply tee’d off the wiring inside the meter where it connects to

Solderless N-Type Connector Fitting

Posted on July 22, 2015July 28, 2015 The Engineer

I thought I’d detail the process I use to fit an N-Type connector to a coax cable, as I don’t usually solder these connectors. Before stripping, fit the backnut, washer & rubber seal onto the cable. The cable is first stripped back to reveal the shield. This cable has a

GY561 Frequency & Power Meter

Posted on July 18, 2015July 19, 2015 The Engineer

The latest addition to my radio shack is the GY561 frequency & power meter, which has already come in useful for measuring the output power of all my radios. It’s a small device, roughly the same size & weight as a stock UV-5R. Power is provided by 3 AAA cells.

Arduino Based SWR/PWR Meter – The Board

Posted on July 8, 2015February 25, 2017 The Engineer

I recently posted about a small analog SWR/Power meter I got from eBay, and figured it needed some improvement. After some web searching I located a project by ON7EQ, an Arduino sketch to read SWR & RF power from any SWR bridge. The Arduino code is on the original author’s

Wouxun KG-UV950P RF Connector Replacement

Posted on July 5, 2015 The Engineer

In my original review, I noted that this radio was supplied with a SO-259 socket for the antenna connection. However I’m less than fond of these, due to their non-constant impedance, which can cause signal loss issues at VHF/UHF. Because of this, I’ve replaced it with a high quality N-type

Moonraker SWR270 SWR & Power Meter

Posted on July 2, 2015 The Engineer

As I’m building up my radio shack, I figured an SWR meter would be a handy addition to my arsenal. This is a cheap Moonraker brand meter, which also will measure RF power. Above the front of the meter is shown, with the moving coil meter movement on the left,
