I've come across pix of some R4Cs that have a filter, twice as large as the
other plug in filters (more depth), on the back of the radio. It usually
sits in the 1.5 kc position (bottom).....
Can anybody tell me what this filter is? Is it a 16 pole type??
Thanks,
Ed NI6S
PS: Also looking for a Drake TR5 to
buy....
