N1RX_Z-Match

Here's a QRP Z-Match Tuner I built into a Whitmans Sampler tin. It is similar to the Norcal BLT design. The transformer core is a T130-6 from Amidon. The tuning caps are dual-section polyvaricons, 270pF per section. Also inside is a resistive SWR bridge with LED indicator. This tuner can drive balanced or unbalanced antennas.
