Using the New MiniVNA Tiny to Test Another 6M Beam Building Project
Sweep Test of Homebrewed 6 Meter, 3 Element beams
I used the IFR 1600 and the return loss bridge to run a sweep of the 6 Meter beams I recently built, and here are the results. On a 10 MHz wide sweep, the peak resonant frequency shows up at 51.2739 MHz. At that frequency the analyzer is seeing -83.7 dBm coming back through the […]
IFR 1600S Added to the Bench
A new tool has been added to the KK4ICE workbench — an IFR 1600S service monitor. The spectrum analyzer and tracking generator functions included in this piece of gear will make the tuning of duplexer cavities, filters, and antennas even easier than before. Add in all the other great features and this machine will serve […]

The PVC handle added to the end is simply to make it easier to hand-hold. Initial testing of the antenna brought […]
