![]() SignaLink USB Audio Transformers and Other Changes We will be looking into this too so that we better understand what is happening, but as noted from our testing, the lower deviation still works very well. However, when we use a SignaLink USB that has been modified for more output and is capable of driving the radio to 2.5KHz deviation (TX modulation was verified to be clean and undistorted), the Auto Tune feature still lowers the level back down, and the resulting deviation is around 1.5KHz. This is the case with the TM-V71A that we are now testing with. We would also like to note, that as previously mentioned, some Kenwood radios appear to need more audio than the stock SignaLink USB can provide to reach the recommended 2.5KHz deviation. Since the recommended deviation is 2.5KHz, we plan to do some additional testing to see what affect deviation has on throughput, and what might be done to get the Auto Tune mode to actually set it there. We used the VARA program's Auto Tune feature to set the TX level both ways, but regardless of the adjustments we made (both TX and RX levels were experimented with) we always ended up with a deviation of approximately 1.5KHz. It should be noted that our testing was done with both radios underdeviated. I ended up turning it off when I use digital modes.and back on when I finish. My Kaspersky security software is a reaL pain. Please let us know if you have any further questions. Just be sure you have things backed up in case Windows does something unexpected. Windows Reset or a restore point as you suggested. New USB port to force a driver reinstall. If that doesn't work, then you might try in stalling the SignaLink on a It might still be there even if it doesn't show up in device manager. The next time it happens, you might want to ignore device manager and simply go through our Windows 10 setup to see if USB Audio Codec is displayed there. Regarding your question about the SignaLink, unfortunately we've never heard of this before. Here is the reply I received from Tigertronics: My computer keeps removing the Signalink USB sound card from my device manager? Suggestion on how to stop this please? I am having problems with my Windows 10 O/S and my Signalink USB device.
