I finally got the keyer figured out. I needed a PNP transistor as well as the pullup to get the keying right. It works and is ON the air as I type. Reception reports would be awesome. I'll measure the frequency in a minute and post my results with the HP. Mike>WE0H http://www.we0h.us/lf.html 185.303kc QRSS/CW ID is "WE"
