[Lowfer] Sunday screens for WA

Sun, 27 Jan 2002 13:27:49 -0500

Mitch. Very informative shots for me! This is alternating -6db with 
different experimental slants through the night. Stayed up until 4:00 trying 
to design a simple 4 slope circuit out of two contol bits from the computer. 
Turns out that I need one of them to discharge the sweep capacitor so I 
ended up with only two slant angles. After getting up today it dawned on me 
that I need a major sweep voltage (simple RC net), that is reset every forth 
time, or so, with bit 1, and a controlled switch that turns on the regular 
FM sweep capacitor, with bit 2, at the beginning of each slant. This will 
produce a infinitely variable slope.

Really helpfull, Mitch!

Bill
