  1. I agree that it’s annoying, maybe even close to being a bug. I understand why this problem exists but if I were Lectro I would have considered using the same pilot tone signal or whatever so that block 470 and 19 could tune each other’s overlapping frequencies without any extra steps for the user.
  2. I say get the same system as your colleagues and crew you regularly work with have. For me that’s Ambient and they are durable and mostly trouble free. Good advice not to let it snap back to avoid lock ups.
  3. I’m not sure you’ll get better answers here than you already did on Facebook but worth a try. My money is still on the HDMI connection having some unintended consequence.
  4. I wonder if the batteries weren’t well balanced charge-wise if you’d have one starting to charge the other?
  5. My gut feeling is that Jim Feely has the right idea. Verizon or T-Mobile can't send you a fine it has to come from the FCC and the FCC won't investigate anything unless there's a complaint from a license-holder. I think if we're strictly talking about operating in the block24/25 guard band or duplex gap then there is very little chance of getting a complaint directed at you. If you're out in the middle of block 27 or 28 or going rogue in 24/25 I'd be slightly more concerned.
  6. I had RF issues (buzzing around certain set lighting rigs) on my brand new (2019) 50s and the problem resolved after I re-wired the female ends of the XLR shorty cables. All I did was solder pin 1 to the ground tab. I’d start there.
  7. Most of your questions here are over my head but I wanted to share something I noticed on a DIY project I did. I assumed that two dc sources feeding one load but isolated with diodes would perfectly draw from just the higher voltage source but in my case I found that the load pulled power from both sources but it was not in equal amounts. More power was pulled from the higher voltage source than the lower voltage source. I’m not sure if that’s to be expected but that’s what I ended up with in my case.
  8. I’m not sure I agree with this statement. I have yet to hear about a single case of a production sound mixer getting in trouble for operating on illegal channels. Not to mention there are gaps in block 24 and 25 that are legal to use with limitations.
  9. This is all true but just be prepared for a $600 bill. SD service is no bargain. But they do a good job of course.
  10. That’s good to hear. I struggled to hear some lines on discovery.
  11. How does the RF performance compare to the DSQD half rack receiver?
  12. This is probably my record so far. About 9 pages if I remember.
  13. Hey Larry, just curious… even when using a passive antenna that has DC protection such as the SNA600a is there any effect on RF performance or other possible side effects from having antenna power turned on? Years ago I was using a Sennheiser quadbox (for ek3041) and I remember getting lots of spray and interference when using two coax whip antennas. The Sennheiser box always had 12V on the antenna inputs.
  14. Glad you found a workable system. Sounds like a real nightmare though. If you have to add 4 other very expensive pieces of gear to the Roger setup to make it work I’d say the Roger is a load of crap. I used it once and thought it was trash.
  15. Frequency range? Could you use this with two Comtek 216 transmitters?
  16. So I tried this with an ancient android phone I had laying around (Motorola Droid Turbo) and a nooelec smart sdr dongle from a few years ago (not sure if it’s the latest version) it would scan sometimes and then not. The debug in the SDR driver claims that it’s not getting enough power from the phone. Have you found that most recent android devices provide sufficient power to the dongle? Are the Google pixel phones a safe choice? I have tried using a “powered” OTG cable which has a y-split to attach a charger but the problem there is the phone seems to decide to only do one thing at a time. Either use the dongle or just charge but not both. Maybe if I used a dumb power supply it would work but phone chargers or battery packs seem to be too smart for their own good in this case.
  17. Can you elaborate on the gain setting? Why is the default "2" and when would it be useful to change it? This is very cool. Not the most intuitive but that's ok. The more I use it the more I see the logic.
  18. Is there a demo version? I have an older Motorola phone laying around I’d like to try but not sure it will work.
  19. It will work just fine. Ignore the highly respected professional lol. It will also work fine plugged into the bottom of the pole. most pole manufacturers make an accessory bracket to do just that. It will also work clipped to your belt with 20’ of cable between the transmitter and the mic. In theory your expert might be right but in terms of practical useage he’s full of it.
