KMIK HD radio reception in Australia

D

dxer2_2000

Hi

KMIK & KBLA were both huge tonight. KMIK was flashing the "HD" logo. Even a faux CALL SIGN came up on the display!!! "OFMN" was displayed instead of "KMIK" :eek: - so at least I got some sort of PAD data, even if not correct ;D

receiver: Sony XDR-F1HD HD radio / 200m longwire

dxer2_2000 @ Numeralla NSW Australia (100km or so south of Canberra)
 
Yep: up there "in the glove compartment" (higher AM/MW frequencies beyond 1500 kHz) the propagation is pretty much like shortwave at times. And 1580's got a 6-tower night pattern with four lobes - by far the biggest one is aimed right at you, mate. I bet the effective field in that lobe is a multiple of 50kw.
 
I know the OP fairly well. This reception is not uncommon for him! When KMIK was KCWW & running AM Stereo, he actually got a stereo signal....I heard it on tape myself!

KMIK, and to a lesser extent KBLA, throw huge 50 k lobes at the Pacific. (How *both* got 50k authority, much less ANY night operation---weren't both stations daytime-only at one time?---is anyone's guess.)

I ask this because there's supposed to also be a non-directional 50kW 1580 in Hermosillo in Mexico, not really that far away!

The KBLA pattern coming from a site very near downtown LA has the rough equivalent of 400 kw in the night lobe. Almost all the power goes into about a 35° arc, which gives that huge power in the main lobe. KTNQ and 1150 in LA have similar big, big lobes (and they are diplexed).

Did you actually receive the stations in IBOC or did you just receive the data and flash the HD logo? The reason I ask is that the HD letters also flashed on my Sony at night on several IBOC stations from hundreds of miles away but I could never receive them in IBOC. In fact I could never even receive a 5KW station here in HD from ten miles away which blasts in in analog. This was with 400 ft long wires. I'm in a better location now with two beverage antennas, I might pull out the Sony from my storage space and see what happens here with these antennas.
 
I'm not the OP, but I can tell you that I often get the flashing HD logo without the HD/IBOC effect. My local Radio Disney WMYM 990 in Miami displays "WMYM" on the Sony, but I never ever get the HD signal, as I am too far from their tight pattern. (KMIK is also Radio Disney.)

The only HD signal I get is WSUA 1260 Miami....nice and consistent in the day, but sporadic at night.

Frankly, I am still awaiting Radio Enciclopedia in Cuba (AM 530) to go HD.....not holding my breath ;)

Radio Reloj has been broadcasting on 861 lately, I caught them on their first night last month.
 
Fidel and Raoul paying royalties to iBiquity for HD-AM? THAT would be the day.

These guys are still living in the Bay Of Pigs days. Last I knew Radio Havana was still presiding over the old Radio Swan SW frequency of 6000 kHz, that simulcast the anti-Castro American AM 1160 off the Honduran coast.

"Dollars for propaganda, but not one penny for tribute, RF robber-baron capitalists from Maryland!" :D

(To say nothing of the fact that if, as one suspects, the number of HD-AM receivers in daily use in North America can conveniently be totted up on the fingers and toes of all frequent posters here, the number of potential HD listeners in Cuba has to be a NEGATIVE number.) ;)
 
How many signal bars was the analog signal registering?

I only have the included loop with my Sony, and with the overcrowded AM dial in the states, its hard to pull in much at a distance without a good setup. My farthest HD lock with call letters so far is WBBM at around 600 miles and it was coming in with 3/3 bars on my Sony that night.

Getting a US based signal from Australia is pretty amazing itself, but getting some HD data is impressive.
 
KMIK peaks at 3 bars. HD audio would never decode as most of the digital carrier would be buried under 1575 (Wollongong NSW) & 1584 (Narooma NSW). the het from 1584 tends to be very annoying.

I'm sure their ancient noise generations also are more reliable than the AM IBOC equipment, considering how often American HD AM stations go off. ;)

Many of them sound better on the air too.
 
I'm in El Cajon, CA, and 1580-KMIK is very likely my strongest nighttime station here (that's not usually received in the daytime, although within several weeks either side of the winter solstice it can make an occasional appearance around local noon. They are about 299.67 miles from me at a heading of 79.39°, blasting 3,458.76mV/m @ 1km toward me at night. Earlier this evening I actually saw KMIK peg the digital signal strength meter at 63,25 on my Tecsun PL-380, using only its built-in loopstick antenna. :)

dxer2,

Do you ever get any North American stations on the lower end of the MW band or is it just the stations on the higher frequencies?
 
Cuba should just get HD transmitters for the frequencies it jams. Instead of us knowing that Cuba is the source of jamming, all we would hear is IBUZ. Plus they can jam the entire AM band with IBUZ so that no news from the US makes it to Cuba. Let them broadcast the IBUZ with 5 million watts and it'll jam AM reception all over the world.

We don't need Cuba to jam the AM band, we're doing it ourselves with HD radio.
 
Stations on the low end are much harder but the more common one heard is KNBR 680. I've also heard 710 KIRO, 570 KLAC, 740 KRTH, 660 WFAN to name some.
 
Is 760 KFMB San Diego, CA, USA possible there? It's 50kW directional with a lotta power aimed out that way. Their transmitter site is about 7.3 miles from me at a heading of 320°, and they are the strongest nighttime station here.
Also what about 640 KFI Los Angeles? It's not exactly a local for me, but does come in fairly well throughout the day. I'm basically right at the zone of their groundwave coverage where it equals their skywave signal, or at least is within a few dB or so. And is 580 KMJ Fresno possible there as well? It's 50kW, directional with a lot of power aimed due west.
