I think I'd rather just talk trash about them in public forums and social m= edia :) Seriously, I was basically told to buy the new model at full price or go aw= ay.

Subject: Re: [EE] Simple spectrum analyzer Hi there, Bob. I had exactly the opposite reaction from Signal Hound. I originally had the "A" version of the analyzer. I found that the LO leakage out the input port was completely destroying the performance of the Wireless Mic and Intercom receivers that the spectrum analyzer was supposed to be supporting. This was in a live broadcast situation and it took a while to figure out that the periodic (repeating) interference we were experiencing was coming from the Signal Hound located several hundred feet away. What we were seeing was the LO as it swept across the spectrum that we were using. I talked extensively with Signal Hound and urged them to do something about the problem. They offered me the option to upgrade to their about-to-be-released "B" version. I received one of the very first production units. I don't recall how much they charged me but it seemed entirely reasonable at the time. I sent my original unit back to them and they sent me the replacement. Bonus: they sent me the temperature-calibrated version at no extra cost - the first batch of production analyzers were all calibrated over temperature as part of their development process. I got lucky! The SA-44B analyzer has been working perfectly. It is in use at many live Broadcast events, especially live Curling events that originate in North America (both Canada and USA). There are so many channels of Wireless Mic receivers in use at any one time that the lead A2 on the show finds that having a spectrum analyzer is almost essential for him. All I can do is suggest that you reach out to Signal Hound and see if they will offer you an inexpensive upgrade to the "B" version. dwayne At 10:19 PM 9/17/2019, Bob Blick wrote: >Hi Dwayne, >I was an early adopter of Signal Hound, and I have the exact >opposite opinion.
