I spent the weekend building stuff.

RF Probe

First, I built an RF probe using a schematic from the ARRL Handbook.  It’s a pretty simple build, as all I needed was a pair of old test probes, a germanium diode, a capacitor, and a resistor.  I packaged the electronics in a small piece of CPVC pipe, which is nice and unobtrusive.

This is the RF Probe. It fits nicely in some 1/2″ CPVC pipe.

End Fed #2

After W0EA told me I used the wrong coil core material, I built one with the correct material (ferrite, not iron).  I still have the old, so I’ll do some comparisons, but barring any major issues, I’ll stick with the ferrite one.

End Fed #2.
