Bruce, I've owned a Trak Systems 8821 for over a year, and had a problem with the antenna side. Yours may be different.
My unit is designed to work with a powered antenna, and it feeds 12V up the coax to power it. Apparently this is the "standard" voltage for TNC antenna connections - the smaller MCX etc. are 5V standard. In my ignorance, I initially connected one of the regular "mouse" type antennas to it that requires 5V. The antenna worked OK for months, and I only discovered the error when I was fitting another more permanent antenna. Strangely, the "mouse" no longer works on 5V, but seems to get by on 12V. Because most powered antennas these days seem to be 5V, I modded the Trak with a 78L05 in the antenna power circuit to match. So, what you could have done is fried the port on your splitter with the 12V? Just a guess. Regards, David Smith. P.S. Have you got any software for yours? I've got a User Manual PDF for mine if that helps. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
