RE: [digitalradio] Anyone using a Cushcraft R5/ R7 on digital ?

Try wrapping all lines into and out of the sound card through one or more Type 43 powdered iron toroids.  The toroids tend to block RF and they are easy to wrap and inexpensive.  All of the major amateur retailers have these and expect to pay roughly three dollars a piece for them.  Buy 4-6 of ‘em or so.  Basically, the sound card lines act as antennae and the toroids dissipate the alternating current inherent in the stray RF from your vertical.  Or is it that the mass increases to infinity as you approach the speed of light.   Just cannot remember which J.   Try the toroids . . . they worked for me.   Rick – KH2DF/5     From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Andrew O'Brien Sent: Saturday, April 29, 2006 6:06 AM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] Anyone using a Cushcraft R5/ R7 on digital ?   I have an R7 and use if on all bands. I do not get any RF into the computer except for 80M.
