I have recently installed the SV-COM Radio in my RV10 which is a great piece of kit. However, I have a couple questions on the configuration settings. When you enter the COM Radio Setup screen the settings all appear as 0 (Squelch, Sidetone and Mic Gain). After changing the values and saving them, if I then exit out of the Calibration settings and then return to this screen the radio parameters are all 0 again. Otherwise the radio seems to work fine. So, I am not sure why these settings don't seem to be saved (or properly retrieved from the SV-COM).

Also, it would be helpful to know when the parameters actually take effect. When you change the values for example for the Squelch does it take immediate effecct (ie., as you are changing the value) or does it not actually take effect until you save, exit and the EFIS reboots? It appears to be the latter from what I can tell which is not the easiest since it makes setting and/or adjusting the Squelch quite tricky.
