ZS6RSH Shack & RF workbench pictures

Herewith are a few pics of my shack showing the work bench, operating position and parts collection. Certainly nothing fancy but it works for me! These pics were taken in February/March 2014.

I have based my experimental 50Ohm RF workbench on recommendations and guidelines as per the QRP Homebuilder series authored by Todd VE7BPO and also the book Experimental Methods for RF design, EMRFD. I will be forever indebted to these two wonderful resources.

All the test gear is from the 1970's and I am in the process of building test gear also. This test equipment was given to me by my friend OM Monk ZS4SF to whom I will be forever grateful. I also was given a large amount of parts by OM Barrie ZS6AJY including a lovely box of knobs and variable capacitors, some of which are certainly antiques. Thanks Barrie!
