Filters for Drake Radios

Drake TR4 SSB

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

The 1901/1902 are superior replacements for the original SSB units. They are wider bandwidth for better audio.
