I was playing with that last night. Saw the "interactive" option, but never bothered to actually try it.

That's a ton better than the non-interactive mode. Finally got a couple with a flight number. They must come in the packets and guessing the pilots probably program them in if they feel like it (have seen reports of interesting ACARS callsigns). I think the hex code & the tail number are in there more or less permanently.

BTW: Once the flight number is known, can track them at

The latter two also do ADS-B tracking. Non-ADS-B tracking is delayed about 5 minutes from the FAA data.

Seeing DAL264 on dump1090 and saw it on the PlaneFinder map. Unsurprisingly, the data was consistent.

DAL264 departed KMSP and enroute to Amsterdam. In a little while, it should be on HF. Wish I was on that flight.

Planefinder has a database where you can lookup the hex code and get the tail number.

The ideal thing would be a map of the local area (zoomable) with live plotting of received aircraft and their track and an arrow of direction. Have them plot in some color (green?). When nothing is heard from an a/c in some amount of time, it turns yellow then a little bit later goes away. Some vertical tracking would be nice too. The aircraft icon could have the same data to look like an ATC radar.

Haven't looked at the other s/w packages and see what they have.

The antenna I was using was a little UHF stub that came with the radio. At the moment, have it stuck (magnetic) to my NC-183D in the basement (of a split level house, so about right at ground level). Also tried a horiz FM BC dipole which worked fine too. Not sure if one was better than the other.

Did notice a few aircraft coming into KMSP disappeared from my view under 7500'. But will have to watch that better.

Have dump1090 running as well on my MBP.

Now decoding the a/c. Although having only their ICAO address is not all that interesting.

Searching for one of them finds that A8B848 is N661DN, a Delta Airlines 757.

In watching his reported altitude, looks like he's arriving here at KMSP. Looked up arriving Delta 757s around this time and there's one from Los Angeles and one from Phoenix. Welcome to Minneapolis, enjoy the cold.

Doing plenty of damage here tonight.

I've been listening to R Aus since 1988 when I started with shortwave. In recent years, its been 9580 in our morning (CST). A few weeks ago, discovered them on 7240 when they leave 9580 and its usually pretty strong for a little while, then it fades as the sun continues to rise.
Used to be on in our evenings in 19m. Haven't had much luck lately with them there. We'll see if success on 19m returns in the summer.

While it may not be specifically NAm, they shoot it out to the Pacific and since we're on the other side of it and the signal is strong here, that's close enough.

Last fall, I picked up a Newsky DVB-T (with the E4000 tuner).

It gets the job done and for its price, can't complain. Does seem like there's images all over the place with it, but could be overloaded by the GP-15 on the roof.

Have listened from the FM BC band up through 900 MHz. Not much to listen to on the 800 MHz around here since the large public safety system is APCO-25 and of the few services on FM 800MHz, they're trunked.

Off the top of my head, the remaining broadcasts to the U.S.: Australia, Romania, China, Cuba. New Zealand used to come up here in the evenings, but haven't heard them lately (could be conditions). Spain comes in well here, but don't know if they're sending to us.

Greece still comes in pretty decent, but don't know if they're sending that to us.

Past few weeks have been picking up Deutsche Welle broadcasting from Africa.

Haven't had much time lately to take a survey of the bands.

For decoding NAVTEX, I use YaRD. Its pretty slick.

Hahaha... Lilek's site is great. Minutes turn into hours. Hours turn into days.

However, haven't looked at it in a while and appears some major changes.

He used to have a podcast called The Diner. Wish he'd start that up again.

The Alex Jones show can also be found on WWCR on 4840 kHz M-F starting at 0300Z and I think on various MW stations around the country.

Could this be a spur or an image of 4840? Difference is 898 kHz. Do you have a local station on 900 kHz (could be mixing that with 4840)?
