  1. Be careful with high temperature soldering. I learned the hard way! I had to solder some female SMA connectors to PCBs and I decided to use lead free solder. I just had got a brand new temperature regulated soldering iron... And I badly botched it. The temperature damaged the connector dielectric material (and the circuits were supposed to work at 1 GHz) and the result was a complete disaster. Lesson learned.
  2. Now imagine that Schoeps clone company that even copies the ads. Will they copy the fart?
  3. You can hide a lav, transmitter and antenna inside that promising radome! Even pros (and I mean two friends who are actual experts on RF, one of them worked for Agilent in Santa Rosa and they are university professors) say that RF can be a bit of voodoo now and then. Now, seriously. No metal in the clothing? I mean, a bodice with some metal wires or something similar? Something must be detuning the antenna. Maybe she is sweating a lot and adding some isolating material between the antenna and the clothes might help?
  4. I forgot: An easy source for radome material can be aquarium stores. They use to stock stuff for making aquarium backgrounds. I remember some of it was thick paper with a rock like texture. It would probably pass.
  5. Apologies in advance if my suggestions sound silly! Is the antenna pointing upwards? If it gets too close to the metal necklaces I would try pointing it downwards instead. As for stone walls, what about hiding an antenna and running some cable? You can build a radome with some RF inert material. Even simple paper (there is paper available imitating stone textures) covering the antenna should work.
  6. I have volunteered to be a Guinea pig in the phase III trials for the Curevac vaccine. I haven't been inoculated yet and of course I may get a placebo instead (50% chance).
  7. I think it's an interesting development and I dare to say it will be more widely used than you imagine! I work for an ISP and a couple of years ago a producer (a real one, I mean, not a short feature amateur) approached us for a solution to set up a distribution facility. They were shooting a feature and they wanted a quick way to distribute takes, dailies, stills, exchanging them with audio post, vfx, lab, even the ad agency to make press kits available. Everything. It was also used for final delivery to distribution for a year or so. We set up a high availability sto
  8. I would stick to a known good powerbank. The MixPres are power hungry and USB power is non trivial. I was experimenting with using a MixPre as an audio interface for an iPad (to run SMAART tools on it for live sound) and due to the flaky USB power provided by the USB to lightning adapters I had startup problems (it took several attempts to boot!) and when the AA NiMH ran low the MixPre entered a reboot loop. Interestingly, the reboot loop didn't seem to affect the audio flow from the microphone to the iPad. Turns out that the FPGA keeps pumping samples once it's been co
  9. Looks like that, I've seen similar on other forums. Probably other posts will contain links to advertisements.
  10. I agree. And it's a shame that many companies are relying on Facebook for customer communication instead of setting their own systems. Of course it's cheaper. It reminds me a bit of the situation with the Flash plugin. I always refused to install it because of critical security and privacy issues and sometimes visiting the websites of pro audio manufacturers without it was a real nightmare. Of course Facebook is worse, their behavior seems to be outright criminal.
  11. Late, but for the record I connected my MixPre-3 to a laboratory power supply measuring consumption depending on the operating options. I found out that Bluetooth is essentially free. After all it's very low bandwidth status updates for the meters and time code, it does not send audio after all. The worst offender is the gorgeous screen that, at the same time, you can see under bright sunlight.
  12. True, but I was thinking about the non linear effects, ie, receiver saturation. In a link with enough interference to cause intermodulation on the receiver the directional antenna may be more beneficial on the receiver, as it will attenuate off axis interference (unless Mr. Murphy makes the powerful interference exactly on axis) And in this particular application there is more bandwith from the "transmitter" to the "receiver" (audio) than the reverse (feedback/control signals from the "receiver" to the "transmitter"). Just from a theoretical point of view
  13. I think some improvement can be expected. For starters, the transmissions won't be symmetrical with more bandwidth being used for audio from the transmitter to the "receiver" compared to the feedback signal sent from the "receiver" back to the transmitter. So, a properly aimed directional antenna would at least help reduce interference on the most critical point. Unless, of course, the worst offender is aligned with the RX and the TX. In that case, miracles don't exist
