  1. Things are pretty bleak for mac. The only one I found a few years ago was RTLSDR Scanner and it works okay. Theoretically QSpectrumAnalazyer could be made to work and have better performance but I haven't bothered building it. It's just easier to run linux.
  2. The cheap SDR dongles can be made to sweep as well by reducing the window size and performing FFTs on sequential, overlapping samples over the frequency range of interest. The open source rtl_power is part of the rtl_sdr driver package and does this very thing and is also the backend for many of the spectrum analyzer GUI applications. Maybe I'm wrong but I assumed RF Explorer behaves in the same way.
  3. I listened to a demo of the CM170 at Gotham a while back and it was clearly a knockoff of a MiniCMIT. Didn't sound nearly as nice as the real thing but not so bad as to be unusable. I'd class it in the same rank as an Oktava.
  4. As I understand it, Lectro's +5 setting is 5dBu output at full modulation, meaning that's as loud as it will get. In the case of the 833, outputting tone at +5 from your receiver into a line input at unity gain should read -15dBFS. In the US, it's common to align 0dBu with -20dBFS. So in theory, this means you would add 15dB of gain to your line input to get the max output of your receiver to match the max record level of 0dBFS. However in the real world, most people don't set the transmitter gain to utilize the full modulation (to rightly avoid the TX limiter) and you end up needing more input gain to get a healthy record level. No worries, the 833 has plenty of gain to account for this. In short, follow Larry's paper bag gain setting procedure described above and you'll be good.
  5. Once Dante AV gains more adoption you could send your mix to Video Assist and bring back the camera feeds over the same cat5.
  6. The 416 also uses the tube with consecutive holes of varying diameter. I boomed for a mixer once that claimed the slots on the 416 mattered which way they pointed but I could never hear a difference. I tried to open up my CMIT to see what it uses but the interference tube is fully enclosed with the capsule. A flashlight didn't reveal any of the holes behind the slots like on a 416 though.
  7. Not necessarily true. It holds true if you perfectly match the gain staging between wireless and recorder. But that doesn't always happen. Imagine a scenario with unpredictable dynamics and the wireless manages to transmit the audio cleanly but the gain of your recorder's input is incorrect. This is where the magic of a floating point comes in and you would be able to recover clean audio that would have otherwise clipped or been too close to the noise floor of a 24 bit fixed point recording.
  8. You'd have to import your scan file from the RF Explorer. If you don't have a Venue, I personally think Shure's Wireless Workbench is more flexible and powerful. If you want real time scanning with your RF Explorer and frequency coordination built in, you could use Clear Waves.
  9. If you solo a channel, the gain knobs should still adjust the appropriate channel. However when you select a channel, it goes into "fat channel" mode where knob 1 adjust gain and other knobs adjust the other channel parameters. You can custom map functions using iCON's computer software called iMap but I'm not sure why you'd want to change the default values. If you had the M+ instead of the X+ you'd have a few options for custom mapping in Sound Devices' "controllers" menu.
  10. Copy that, missed your updated post. Glad it's working for you!
  11. Looking at that guide, I'm questioning whether it installs a non-standard version of linux. Did you follow the directions to enter a shell and startxfce4 first before logging in? Depending on what version of Ubuntu is installed, you may be able to log in as root. Failing that, I'd just wipe and reinstall linux, taking care to note what username is entered at the prompt when installing.
  12. To go back to the original problem of "no such user". Try entering in the terminal "sudo adduser $USER dialout" without the quotes. The $USER bit should autopopulate your current username. Edit: Actually seeing this part, looks like maybe the group is called serial? You could also try "sudo adduser $USER serial" to see if that works. Make sure you log out and back in or reboot before proceeding.
  13. I've used RMGI tape in the recent past with good results but it seems the formulas were once again bought and now distrubuted by Recording The Masters. I'm not old enough to know the setup specs for 968 but RTM has thorough documentation so you can find a formula that matches closest.
  14. Is the limiter in the transmitter engaged? Is the distortion present with it both engaged and disengaged?
  15. The Shure UA860SWB covers 470-1100 MHz for an omni pattern, the Wisycom LFA covers 410-1300 MHz for directional. If you want to "skip" a particular range, you could either combine multiple antennas before your distro or use a filter inline.
