3ghz reciever

KD8EYF · #1 (**permalink**) 09-25-2009, 07:43 AM

hey you guys that own the ar8200 or similar radio that receive up to 3ghz, i want to know what is up there between 1.296 - 3ghz to listen to? i know theres 2.4 ham that you might be able to hear analog cw/fm but im guessing everything else is digital crap right?

To be honest very little, I have an Icom R20 and have never heard much above the 800MHz trunking band.

I also own the aor 8200 mk3 and very rarely do I go to any of the higher frequencies due to not hearing anything there. Anyone have any suggestions as to what can be heard on those higher frequencies?

There really isn't much that's actually listenable above about 960 MHz. There's some amateur repeaters on the 1200 band (closer to 1300, really), and at 2304 some weak signal ssb and cw amateur activity, but that's going to be sparse and difficult to capture with a consumer grade receiver. There may still be some analog marine satellite activity around 1500 MHz, but I understand that's going away to digital modes. I really don't know why the manufacturers bother covering beyond 1300 MHz at all... it's a waste of time and money.

will give you an idea of what the FBI is up to between 1.755 and 2.4 GHz, and higher.

I'm not sure what we're supposed to see with that link, but I sure didn't see much of interest.

1755 Mhz is within the Federal point to point band, so it's likely that signals there are going to be multiplexed, possibly digital. It could still be wbfm with ssb subcarriers on it. That could be demodulated, but is probably beyond the capability of most people.

hi our police here are on 468 mhz here apco25 fully encrypted also there are police up the hunter valley from me that are on 78mhz analog fmn ,our federal police are on 480mhz and up i believe .also about the fbi i assume that the fbi signals are encrypted that high up i guess theres also police freqs here on 4mhz ssb im not sure if there encrypted but i know the power is 400watts anyway ,thanks hamguy nsw australia

i have a aor 8000 i got from the usa a few weeks ago its unbelievable what functions it has. im also trying to get an aor3000 400channel scanner which were so expensive here to buy in australia ,you look at the aor 5000 etc here there i think there over$2000a the 8600mk2 is $1149aus or about$1000us ok .also the icom r20 ive never played with but there like the current model the prices on them are between $700 and $817a. if you want to look at the prices of how much australian people get charged for things new and used check out Andrews Communications also Icom | Yaesu | Kenwood | Diamond | Cushcraft | Strictly Ham Australia's Largest Amateur Radio Dealer! ,thanks david nsw australia .

Ok. That's much more interesting than the previous link.

It boils down, however, that it's not likely to be something that could be received with a consumer grade wideband receiver. There's a ton of signals up there, and nothing to listen to.
