I spent the morning preparing for my first Pegasus mod: the conversion from a T/R relay to a silent high-voltage transistor. I then discovered that the Pegasus is already designed this way! In fact, no modification was needed and a conservatively-rated 2N5657 350-volt @ 1amp switching transistor is used as an open collector to the rear panel Ext. T/R line. I then put the cover back on and cooled down the Weller. This is the kind of mod I really like and the Pegasus works great into my Alpha's 70-volt T/R switch line! -Paul, W9AC -- FAQ on WWW: http://www.contesting.com/tentecfaq.htm Submissions: tentec@contesting.com Administrative requests: tentec-REQUEST@contesting.com Problems: owner-tentec@contesting.com Search: http://www.contesting.com/km9p/search.htm |
