We can now supply SSB filters for the Drake TR-4. We have both USB and LSB filters which improve the audio bandwidth to 250 2750 Hz. They are superior replacements for the original SSB units with wider bandwidth for better audio.

These 9 MHz filters will also be of use for experimenters building high quality radios.
