Jason Walle Posted July 27, 2022 Report Share Posted July 27, 2022 A little background first... I have been using UCR411s for a few years and had 6 of them in a larger ORCA bag running into an Audio Wireless antenna distro unit and that distro was using a pair of Betso Bowties. Great setup. Always found clean channels. I had 2 UCR411s in Block 470, 2 of them in Block 19 and 2 of them in Block 20. That gave me a little more flexibility if one block was more congested than another and I didn't need to run all 6 at the same time. All transmitters I use are Lectro LTs in the A1 band. I just bought a DSQD to go in my bag and reduce a lot of clutter and some weight and get current with Lectro tech. I can now use Wireless Designer, which is great but I'm getting a lot more RF noise when doing scans vs my 411s and I have no idea why. If I scan A1/B1 on the DSQD I don't really have anything clean under 20 dBuv. On the same channel on my UCR411 it's super clean - like nothing on the scan. I'm using the same Betso Bowties as before. Same short LMR-240-UF Ultraflex Cables from DSQD to the Bowties. See photos here - same channel on both the UCR411 and the DSQD. Way different scan results. Standard whips on the UCR411 for this test. Any suggestions? Quote Link to comment Share on other sites More sharing options...
karlw Posted July 28, 2022 Report Share Posted July 28, 2022 Jason, I understand you talked to Gerald in our service department about your concerns. Was he able to answer your questions? Quote Link to comment Share on other sites More sharing options...
Jason Walle Posted August 4, 2022 Author Report Share Posted August 4, 2022 Hi Karl - Yes, Gerald is awesome to work with. Phone call, various emails. I told him I know "you're doing your job" but to have that level of help until it was resolved is why I'm a Lectro guy for life. This is just an FYI for those that may have a similar experience switching from UCR411s to DSQDs. There is definitely a little more "noise" pickup on the DSQD but not nearly as much as I originally thought. It was 95% just a matter of the scales being very different. I thought they were the same so seeing 2x or 3x the levels had me worried at first. The left is a UCR411 scale. It is 2x roughly up to 10 and then jumps a lot. 1uV = 0dBuV 10uv = 20 dBuV 100uV = 40 dBuV 1000uV = 60 dBuV Quote Link to comment Share on other sites More sharing options...
