Laptop Inverters vs. HAM Radio

[Brad Emel]

I've had the exact problem you are describing. I have a Kenwood 707A and a 400 watt power inverter. The radio and inverter are wired directly to the battery, + and - using different wires. My solution was to purchase a noise filter from HRO for my 707A. It plugs in-line to the radio power cables. I haven't had any noise issues after installing the noise filter. My inverter and radio are about 4' apart.

I linked the wiring diagram for my Xterra below. The only difference is the noise filter is connected to the radio not the inverter as pictured. Also linked to my page that has some more images of the install.

Tony,

As few years back, I had an inverter and ham radio wired to the same feed. Whenever I transmitted on the ham radio (at med or high power), it would take out the inverter that ran my desktop computer. The way I solved this was very simple.

I ran two positive feeds from the battery to my equipment. One is solely for the ICOM dual band ham radio and the other powers two 750 AND 500 watt inverters (they run the flat panel monitor, desktop PC, etc). Since then, problem solved. I don't have any filters or extra batteries either. I use a beefed up car battery and David Drummond's idea of using a WalMart battery b/c of the warranty and ease of exchange is very very smart.

I sincerely hope this helps.
