[amsat-bb] Information request

All: 4 or 6 years ago, there was an article in the Journal regarding a 2.4 GHz antenna tuning aid. As I recall, it was basically a return loss bridge, with an included VCO, and a DC or meter output. I'd like to revisit that article, but have not yet found it in a quick scan of tables of contents from my collection.

Does anyone remember when that article was published? I'd appreciate a pointer; probably have the issue, just can't figure out which one.

Thanks & 73, Jim wb4gcs@amsat.org
