rtl_tcp SDR App Reviews

Downloaded then deleted once I saw the setup requirements. Refund possible? Thanks, Eric KC1OAV

I use this to connect to a pi with SDR I have across the yard on top of my outbuilding, fiber backbone connects that building to my home network. It works like a champ! I can sit on the couch with my iPad or phone and listen or sniff out noise away from the radio room… thanks!

Since there’s so many things that I need to do to actually make it work since you have to plug it into something by the way, I need extra ways for this to work and it’s pretty complicated and stuff so I need some extra things for it to work properly that you can go up to one gigahertz I think I’m trying to find the perfect SDR that doesn’t require such complicated stuff like plugging it in

Simple, basic remote sdr receiver/ controller- even has a built-in up converter setting. Waterfall looks good lots of different demodulation options. Highly recommend. It’s not some incredibly fancy software, but it does exactly what it says it does. Pretty amazing with apples limitations. Surprising how well it works no frills SDR receiver.

It isn’t perfect but it really cool to be able listen and even transmit using my Hermes Lite HF rig from anywhere! I think there’s a memory leak or some issue because after a few minutes and several transmissions it starts having issues. But I’m sure that will get fixed eventually. Nice job!

I have an RTL-SDR blog v4 connected to a fedora 43 server that I’m running rtl_tcp on. This app is working really well on both my iPhone and iPad, connecting to rtl_tcp. Sounds great and was easy to connect. Would love to see the ability to save and scan channels in this app. Would also be awesome to be able to scan a frequency range.

Looking forward to using this app as it matures. It worked right away with my Raspberry Pi RTL server. It even works OK over my VPN. Features that it definitely needs in future updates: 1) The upconverter frequency needs to allow a more exact calibration down to 1 Hz. 2) Same for the PPM value. At least 3 decimal points are needed for accuracy. 3) A slider would be helpful for fine tuning SSB and CW signals. Say +/-1000 Hz. Maybe along a vertical edge. Nice effort, well done. Keep up the g

The BIG variable is network bandwidth. But at the lowest sampling rate it works good. Using a Raspberry Pi 3+ server. Up/Down tuning buttons would be nice with it changing the selected frequency digit for slow or fast tuning.

I know Apple makes it harder to do true hardware. I use SDR sharp and sdr console on pc. This is pretty close on iOS. A little temperamental at times with settings and network server config. But best out there on iOS I have found. Wish it had native air spyserver.

I combined $25 sdr, Ham It Up, Youloop antenna with a raspberry pi and how I have a internet accessible shortwave radio.

Please fix the memory save process. Also please add more memories..

This is the ONLY (iOS) RTL-SDR application in town. It’s get the job down, albeit crashes occasionally and could use some polish. I’d like to be about to pinch bandwidth. Needs a LOT of work. I sincerely hope they continue developing. Could be a great app. Not worth $10, I hate to say..

- bookmark of frequencies is too small (only allow to save 5 freq) - real-time saving - auto scanning

Works, interface is terrible, cannot slide back without retuning half a frame, can slide forward any before retuning, fix this please!!!
