The eprom.zip file download on the sonic web page is the Neutec Eprom Image package that I've made available. Within the zip file is a description of the programmed eprom information. Enjoy and drop us an email if you have specific questions.

The available service manual will provide you the eprom programming information. I provide an available download of the SM-1645L Radio eprom image in Intel .hex and Binary .bin formats along with a short text description/list of the 3 programmed radio frequencies contained within.

We/I get a lot of Email from visitors who drop into these file down load description pages via a web search "engine" (like Google). Vistors are not able to locate the file download icon for that specific description page. There is a simple way to find the file download icons on the main www.radiowrench.com/sonic page...

First and best: Use the menu icon just below to the main sonic page.

Second: Back space out the page your now looking at in your browser location line. As an example, using the http://www.radiowrench.com/sonic.so2004.html description page. Remove the last portion of the web location with the keyboard back space key to read http://www.radiowrench.com/sonic then press your Enter Key to reload the main sonic page "just in front" which would probably has the inforamation you're looking for. This works on most of the current browsers at most web sites.
