Re: [BVARC] Test new car for RF noise
allen, just make a small loop antenna at the end of a long piece of coax and connect it to your 706 in your existing car on battery ( not running) and sniff the new car while it is running. AM mode no NB, RF gain max AF gain up windows open and SNIFF Sent from my iPong W5RH On Sep 27, 2014, at 22:32, Allen R. Brier via BVARC bvarc@bvarc.org wrote: Allen R.

Re: [BVARC] Test new car for RF noise
Gents: Just fired up the ol' smoldering iron and built a RF sniffer (show and tell in December); hooked it up to an AOR 3000 communications receiver (60kHz to 2.2GHz) and behold, it seems to work. Now to go after my Hybrid. Should I sniff on the ham frequencies or does it really matter?

Re: [BVARC] Test new car for RF noise
JN, depending on the fundamental and wave shape, the ham band rfi could be from another freq outside the ham freqs. keep going lower in freq to find the fundamental but it could be below rf into ultrasonic or even af like a swithing PS rfi. ARRL has some good stuff on mobile rfi as does alan applegate forgot his call, the mobile info oasis web site. GL. W5RH psrfi can sneak in on ant or on the power cables so pull the antenna/ coax and sniff with power only too.

[BVARC] Test new car for RF noise
I am test driving a 2013 Ford Explorer and wondered if I could get someone's help tomorrow to test it for RF noise. If you have a portable SW receiver or HF radio, or one in your vehicle, I would like to either have you come over to my place or I can come by yours to test it. I have one but don't have a portable resonant antenna available. I need to do it early, say before noon or 1 pm as I have something else I must do in the afternoon. Please call me on my cell phone number below. Thanks, Allen R.
