Please note that what I posted is a great guide to get you started and comfortable with where the broadcasters are but you must know this isnt even the half of it there is much more on HF you have to discover and you will be thoroughly excited with each discovery. Such as when you hear your first Air traffic controller from a 1000 miles away or getting your first SSTV SCAN or WEFAX. All in time just concentrate on one thing at a time and if your up early look at my above post you should receive them easily. Sooner or later you will want to get 50-100ft wire outside to use as an antenna but for now enjoy yourself! Nice to see a new hobbyist! Welcome to HF RADIO!

Yeah, like Token said, most SW listeners -- at least those who don't have SDRs, who instead use portable or tabletop SW radios -- tune the bands more or less by hand, actually using the tuner: you go to the 31 meter SW band, for example (9400-9900 khz) and tune through it by hand, like you would tune through the AM or FM band on an old analog radio.

A lot of digital SW portable radios have a "scan" or "search" function, but those functions tend to miss a lot of the signals that you can hear, because the threshold for those functions is usually set a bit high -- only stopping on the strongest stations. Meanwhile, there are a lot of medium and low level signals that are perfectly readable that those "search" and "scan" functions will miss.

I have several radios with a "search" or "scan" function -- I've never used it. Scanning is for VHF UHF scanners. With shortwave, you just need to know where to tune, and also it helps if you know what you want to hear. Is it broadcast stations? Then you tune the SW Broadcast bands (49 meters, 41 meters, 31 meters, 25 meters etc.). Do you want to hear hams? Then you tune the SW ham bands (20 meters, 40 meters, 80 meters, 15 meters, etc.). Do you want to hear military communications? Then you find a chart with military frequencies, and monitor them until you hear something.

It's a bit different from using a VHF-UHF scanner radio, for sure.

Go listen to some Alex Jones shows on SW broadcast from Nashville, TN on the GCN Network.
I listen on shortwave radio 12.16Mhz SW M-F 11-3pm or replayed at 4.84Mhz SW 9-1AM Central.
If the static is bad then you can stream any broadcasts from the Genesis Communications Network
They do advertise that they have 4 x 100,000 watt shortwave transmitters located over in Nashville, TN.

Wow, I ahd no idea soooo many people listenned to shortwave as opposed to vfh/uhf and 800's.. Well, I'll be hearing those shows today, see what is what in the world, not just my neighborhood. I wonder what wolfeman Jack would be like today. Riot, I'm sire, thx all. Wolfman Jack Tribute - YouTube

In no way am I defending the tech support guy but he probably was trying to say there are no SW Broadcast stations in that range. However, it would be hard pressed to say CB is not active.

It looks like the Grundig S450DLX only supports AM/FM modes. So you're not going to hear much (except CB Radio) between 26-30 Mhz. SSB is mandatory for shortwave monitoring, imho.

1711 to 2250, thats a gap that the seach misses. Heres the rest of the GAPS, that do NOT get scanned, but hand tuned..,Heres the rest of the GAPS. It jumps from 2550--3150-(gap), 3450--3850,gap, 4000-4700, gap, 5100--5800 gap, 6300--7100 gap, 7500--9400 gap, .. On SW2, 10100--11525, gap, 12150--13500, gap, 13900--15000, ngap, 15900--17450, gap, 18000--18850, gap... On SW3 19990--21450, gap, 21950--25600, gap, then it searches from 26100 to 21450. Look at all the gaps. Thats about 9000 worth of khz missed in a 29999 khz radio. Shhheeeeesh, Never get Grundig again! Alinco is going to be the star radio in my collection of radio/scanner products. IT DOES have good reception, not a good search mode..

Default For LF

MaineTrunk for those freqs below 520 kHZ you want to check those about daybreak/dawn hours. I am in West N America and all I can get is 407kHz which is an NDB non directional beacon CW. You may get more, maybe even some radio stations! I don't know if you are using a loop but definitely those LF frequencies would require a decent external antenna I guess.

Good luck your exuberance sounds like mine with the HF frequency hunting. It can be a lot of fun sometimes.

Thanks fleef, I know all about signal searching, many scanners. However,every scanner I've ever owned has it's flaws. Quick example, Uniden 396xt, trying to play with those sub-banks while driving, horrible belt clip, don't do trbo or Nexden. ( I know others don't ) But for the price, I like it. I have height on my side, don't really need external antennas. I got excellent recpetion as is. Besides, when Igo to the coast, I want 2 receivers. Seeing as how the Grundig has no attenuator, nore priority channel, the Alinco will serve fine. I havent had much luck durring the day, searching. Plus, you may be on the 8000 khz range, and someone else talks on 12121, nice to have another search going to catch these airwaves. Like a potato chip,-scanners, you can't have 1..Haha, thx.

I had 12120 ( a strong signal ) set so the digital signal would barely break the rf gain. I could actually hear the signal going in and out as the sun went down. I dont know about the ham digital signals, but here, in local, with rf gain turned to 6, from 14000--14100 is FULL of signals. Thats allegedly ham band? Why all the buched up signals?
