Note: bandwidth is measured by the manufacturer at -3 dB; we measured shape factor at -60/-6 dB.

Note: Collins mechanical filters are no longer in production. INRAD has inventory on hand that should last until sometime in 2024. Once our inventory is sold, we will discontinue offering this item. There is no drop-in replacement available. Note: The #706 installation kit for the Collins 32S-3 includes 2 x 456.55 MHz and 2 x 453.45 MHz LSB/USB crystals. This is reflected by the higher price than for use in other receivers.
