Someone in the Phorum might be able to answer your question directly but I suspect your best chance at getting to that specific information is by visiting the Mulholland Press web site and contacting Robert Baumbach. He has quite a bit of information on Radiobars. Ron references this site as well in his discussion of Radiobars. Robert has a contact page on the web site. Let us know what you learn!
