NARROW-BAND FILTERS

Here�s how to squeeze twice as many customers into your existing spectrum by reducing channel spacing to 12.5 kHz on 450 MHz or 15kHz on 150MHz.
With our IF crystal filter kits and tone signaling protection, you can open up a lot of new channels without fear of adjacent channel interference.
Don�t discard those old radios like Master II�s, Micors and countless others.
Convert them to 12.5 kHz/15kHz narrow band and save thousands of dollars in new radio replacements. Our high quality, low cost crystal and ceramic filters provide relief from interference under Part 90 rules.
Available as individual filters or as complete conversion kits for specific radios. Installation instructions are available for many popular radios. Call our sales or technical staff if you have any questions.
