Is it strong enough to pick up on a portable as you move about your neighborhood? A portable is on my list of things to buy. Many threads on that very topic in this NG, Yeah. I've been saving them. mine's an eTón E1 I've heard good things about them. (And oddly enough, I think KPBS radio was recently offering them as a premium to subscribers.) used with a roof mounted vertical whip, Grove TUN-3 or the discontinued Radio Shack tunable loop for AMBCB can you post here news:alt.binaries.pictures.tools Done. Got it, weird. Almost sounds like some harmonic of navigational radar, are you in the line of fire from Miramar? Hmm. The runways run east-west. I'm due north of Miramar, about 5 miles. I wouldn't expect a harmonic of a radar to be at 6.404 MHz. BTW: I tried the Butternut and the Imax and tuned above and below, but didn't see anything remarkable on the spectrum scope of the 756. IC-756? Nice. Yep, Pro3 Nice. I've read good things about them. but even with all the excellent features it isn't always up to SDG&E's ambiance g and even with the ANC-4, it's still a losing battle some days. I guess I should thank my luck. The power lines are underground here. And I have a yard. So I can string up a modest antenna away from the house and run coax to it. I'm running a TS-440. You a Ham too? Yeah. Got my tech license a long time ago. But I almost never transmit. I've got nothing to say. ![]() Free bander? Heaven forbid, no. ![]() Just a second thought, I seem to recall that those plug-in phone extenders operated around that range. You know, the ones that modulate the AC line with your phone data. http://tinyurl.com/svc2v Hmm. The thing sounds like a somewhat fuzzy carrier that sweeps up and down over a range of about 2 kHz in a generally sinusoid pattern with a period of about 1 second. That wouldn't be the best carrier for a signal. Maybe the sweep would be to block intercept? But there isn't much point in leaving the carrier on 24/7. As I remember from listening to them back in my old ICF-2010 days, those phone extenders were more or less fixed freq and the only sound was like if you pick up the handset of your phone while online with a dialup connection, certainly no sweeping like in your clip. I'm guessing radar. My curiosity is piqued. I need a portable plus a good directional antenna. I've wanted that to track down some of the local noise sources for some time now too (but there are other projects ahead of that in priority). -- rb |
