HDSDR + EzTV666 RTL2832U, Aviation band

HDSDR + EzTV666 RTL2832U, Aviation bandLooking for some airplane chatter, not a whole lot to hear. I only realize a bit in that the signals are AM and not FM. Source

HDSDR + EzTV666 RTL2832U, 70cm area, Smaller radio sets

HDSDR + EzTV666 RTL2832U, 70cm area, Smaller radio setsI looked up 454.025 and 454.050 and they appear to belong to rural EMS. The close overlapping of bands makes me wonder again if there are multiple systems at play again. Source

HDSDR + EzTV666 RTL2832U, Longplay, NOAA Weather Radio

HDSDR + EzTV666 RTL2832U, Longplay, NOAA Weather RadioI let NOAA Weather Radio play for a while, nothing special. Maybe interesting to those outside the US. Source

HDSDR + EzTV666 RTL2832U, Extremely busy 70cm area

HDSDR + EzTV666 RTL2832U, Extremely busy 70cm areaNot sure if its trunked radio, but this section is extremely busy for where I live. I’m curious as well if there are overlapping systems. There are channels only 12.5khz away from each other instead of 25khz leading me to believe that I’m seeing two different systems together. Source

HDSDR + EzTV666 RTL2832U, Decoding POCSAG from VHF utility telemetry (?)

HDSDR + EzTV666 RTL2832U, Decoding POCSAG from VHF utility telemetry (?)Very boring here, it just spits out a number that increments. Hopefully I will catch something more interesting another time. Source

HDSDR + EzTV666 RTL2832U, Trunked radios around the 33cm band

HDSDR + EzTV666 RTL2832U, Trunked radios around the 33cm bandDifficult to follow conversations on trunked radio, but there are still some analog signals around here that can be heard. Quite a bit of digital, however. Source

HDSDR + EzTV666 RTL2832U, Ghost signals and interference

HDSDR + EzTV666 RTL2832U, Ghost signals and interferenceIn the aviation band, quite a bit from 33cm is seeping in causing fake reception. This can be an issue at times when your trying to determine whats fake. Not sure how to counter this and likely because these are cheap devices. Only way to know is to tune the same on a real radio to find out! Source
