International Radio :: Products by radio :: Drake :: TR-4

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.
