August Meeting

By | August 15, 2010

HODARS had a very good meeting and program in August. Dick, K4IQJ demonstrated a two port  Vector Network Analyzer from  Array Solutions (VNA-2180). It can be used as a single-connector device to measure antenna impedances in a manner similar to the MFJ-259 but with a lot more informaion, or as a two-port device to characterize amplifiers, filters where you need to apply a signal to the device input and measure its output. Dick is using it to measure phase and amplitude matching of the three paths in my three-element receiving array.

After the meeting birthday cake was enjoyed, celebrating the third anniversary of HODARS. It was great to see Bob, KD4PK and his wife Ruth, KI4QGM. Both Bob and Ruth joined our club and it is great to have them with us.
