Noise Filter

This can help eliminate the noise! 

Here's another innovative product from High Sierra. We are making these noise filters at this time.  This is a real filter.  It is not simply a capacitor.  There is a power supply choke wound on an iron core (like a real choke) with two capacitors following the choke.  One cap is 1000 mfd.  In other words, it is much like a power supply filter after the rectifiers. 

We are manufacturing two versions.  This one is rated at 20 amps ICAS and the other at 40 amps ICAS.  If you are running 100 watts SSB with the typical transceiver, the 20 amp version should be fine.  If however you are running 100 watts with a 100% duty cycle (like PSK31 or RTTY) the 40 amp version is the better choice.  The 20 amp filter is housed in a plastic case that is about 1.5 inches by 3 inches.

We found it to be an effective filter in mobile installations.  We also found that it helped with the noise generated by some switching power supplies.
