Aloha from Hawaii everyone I have a question regarding the system 100M. I am looking for an envelope module for this system. If I can't find a true 140M module (rare) I will settle for something else. Can anyone suggest an envelope that I can use with the system? Do you know if the Sherman Filterbank envelopes can be interfaced with the 100M? If anyone has an envelope or information on that subject, please email me when you can. Thank you, sincerely, Tim
