IP over DVB-T2 test bed is complete. Essentially WiFi on completely clear frequencies (2305 and 3429 MHz). #gnuradio #dvbt2

@2ftg1 352x288 was the old SIF resolution for MPEG-1 at 25 fps (PAL).

@CyberQueenMara @MehdiHacks

@mnhussein49 @ea4gpz There are only 8 combinations, 1/4, 1/8, 1/16, 1/32 with 2K and 8K FFT size. When you hit the correct combination, you should see a constellation instead of just a single dot in the center of the plot. The "Occupied Tones" parameter is not used, so don't worry about it's value.

@luciangasparini Triax BNC.

@zznop_ @r0ny_123 @vector35 Old school.

@basicallyedd Allan laughing is my favorite.

@supersat @merrittk The old cameras could take a pretty good picture. This is from a Kodak DC280 circa 1999. 1760x1168.

@ZsofiaBodo and

@TheRealMike @AndrewK8EL That's how digital radio is done here. It's called IBOC (In Band On Channel). The signal occupies 400 kHz of bandwidth. But FM stations in each market have always been assigned on alternate channels. So in theory, only out of market stations get interfered with. No fun for DX'ers

@basicallyedd

@W6KSR I'm not an expert, but it looks like an old BN paint scheme. The picture you linked is from 1999, so maybe it just never got repainted.

@Lezzyl_ Used to be on Wide World of Sports all the time (from Islip, NY).

@haroldfeld @FCC Spectrogram of 902 to 928 MHz here in Silicon Valley with just an indoor antenna. Zillions of smart meters pinging away. Be sure to switch to 1080p.

@guycole @aaronbateman22 I remember at some point, the Z-150 was phased out and replaced with the Z-200 (which was a PC-AT clone).

@aaronbateman22 And this was the system that forwarded missile warning messages to the Patriot SAM systems during the first Gulf War. Considered revolutionary at the time, that seems like "bear skins and stone knives" now.

@cyberat2600 I had working on Netscape 4.76 back in 2019. But it redirects to https now.
