The photos that follow were sent to ARRL district manager and co-founder of Zenith radio, R.H.G. Mathews, 9ZN. Many contain early Chicago Radio Labs/Zenith equipment such as Mathew’s spark gap disk, the CRL Paragon, “Amplifigon”, etc. Many early hams were proud to show off their gear to this revered operator.
The following is a postcard simply addressed to “Robert G. Mathews, Chicago, Illinois”. Imagine that reaching him! The sender, Mr. Heacock, had quite a station as you can see. You can read more about this Oregon radio pioneer at this link.
