Hammarlund I.F. Noise Silencer

The Hammarlund I.F. Noise Silencer is a powerful noise reduction option. It is designed to be easily installed in your HQ-180A. Tools required include:  hex nut drive, screwdriver, Phillips screwdriver and small soldering iron. The existing Noise Limiter and this IF Noise Silencer can be used independently or together. This Noise Silencer is most effective in CW and SSB modes where the signal is being impacted by heavy ignition or other pulse type noise.
