| The Model 208 CW Filter is an accessory audio bandpass filter intended for use with the Ten-Tec Argonaut transceiver. It consists of the Model [[245]] printed ciruit assembly mounted in a small enclosure, along with a three position selector switch and attached cable. The 208 plugs directly into the Argonaut Model [[509]] ACCESSORIES socket, whereas a slight modification is necessary when using the filter with the older Model 505 Argonaut. Service Note SN-6-505 details the modifications. | The Model 208 CW Filter is an accessory audio bandpass filter intended for use with the Ten-Tec Argonaut transceiver.
