sdr

Hey everyone! I just got my hands on the new hackrf h4m portapack version, and I am absolutely thrilled! I've been diving into this hobby of sdr devices, and this is my first high performance sdr. Before, I only had an rtl sdr v4. I am really impressed by this device, and it also looks amazing...

Greetings! I apologize in advance if this is posted in the wrong place. I scoured bot forums of RR, Reddit, Google searching including Youtube but decided to post here as this place has the required knowledge for what I am trying to do - if it is possible. I have an RTL-SDR Blog v4 connected...

***SOLD*** Selling Airspy HF+ Discovery SDR which has become surplus to my needs here. Purchased a few months ago. It has been used indoors in a non-smoking environment and is in excellent condition. Comes with original box and USB cable. If you're reading this you likely know this SDR's...

I have SDRTrunk 0.6.0 beta 2 and it keeps telling me that it's not compatible even though apparently from the few forum posts about this that I read, they all say it's compatible, but the software begs to differ. Should I just return my SDR for any older one or is there a proper fix?

Iv'e recently purchased a second SDR dongle to monitor a p25 simulcast system and now im getting the error with the second dongle that says "Error - unable to initialize R828D" Iv'e reinstalled the driver , changed the serial number so that it didnt match the first dongle and it still no...

Selling my WiNRADiO WR-G33DDC 'EXCALIBUR Pro' SDR shortwave receiver. I purchased it new from Winradio in Australia in November of 2022. I've since become a ham radio operator (VA3KTR) and have a great transciever. My Kenwod does everthing I need it to do with respect to listening to the HF...

Does anyone know any pager or POCSAG frequencies in the Halifax area? I know about the two Hospital Paging Frequencies around 138-140MHz but cant seem to come across any others here locally....anyone know any? I've been playing with my RTL SDR using SD++ and the PDW app.... Thank you

*SOLD* at qrz.com. Thanks for looking!

Selling as it is surplus to my needs. I am not the original owner. One of the feet on the bottom is missing, but it is in otherwise good condition. I do not have the original box. Performance is excellent for "DC to Daylight" reception with the correct antennas (not included). Works with SDRUno...

Hello Everyone! I have been trying for the past 24 hours to get my SDRtrunk to work with my RTS-SDR model V3 and I can not hear any stations. I downloaded SDR++ to see if the dongle was picking up stations and it is. I am obviously missing something I just don't know what. My control...

Without changing anything on the Airspy HF+ , antenna terminated into 50 ohms, agc set to medium, same frequency 11396 kHz and no other dsp. SDRConsole shows noise floor at -135dbm SDR++ shows noise floor at -130 dbm SDR # shows noise floor at -115 dbm. which one should I consider is better or...

Anyone been to bagbuilds.com and checked out the SDR mounting system they have put together for a backpack? Its crazy cool in my opinion. Anyone have one?

Airspy is good for up to 1700MHz at 12bit to 16bit bitdepth (lower sample rate modes increase bitdepth, as it still does hardware sampling at the full sample rate but then the driver decimates to the lower sample rate to increase the bitdepth of the digital signal presented to the user...

I am only about a month into having purchased an RTL-SDR dongle and a Tram 1410 Discone Antenna that I have mounted on my old Dish Network mount (minus the disc, the arm now horizonal, and adding a 3' tall antenna mounting pole to the end of the old Dish Network arm). I have watched many...

I gotta say, when I saw the price tag of what it might cost to get back in to scanners, I was completely appalled by the idea that I'd be forced to fork over around $700 on average to a select few manufacturers that are able to decode P25-2/II and then I remembered I own SDRs! I picked up some...
