rtl_tcp SDR App Reviews

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!!!
