September 20, 1985 HOA-5404-1 Bulletin No: Pan Adaptor Module HOA-5404-1-1 Not Recommended For Use With HW-9 And HW-99 Transceivers The HOA-5404-1 Pan Adaptor Module is not compatible with the Heath HW-9 and HW-99 Transceivers. When connected to these transceivers, the sweep from the HO-5404 Station Monitor could be heard in the receiver audio. The sweep noise was heard on all bands. Engineering considers the noise levels objectionable and does not recommend the Pan Adaptor Module be used with these two transceivers. ------------------------------------------------------------------------------------------------------------------- Thats everything I hold up to 1987 that covers the HOA-5404-1 Pan Adaptor Module
