Is the TenTec 4020 QRP transceiver negative keyed? My MFJ 464 keyer does not key the 4020. 464 only keys positive keyed rigs. Anyone know? |

http://www.tentec.com/wp-content/uploads/2016/05/r4020_manual_3-24-10.pdf 12F629 PIC programmed as a keyer. Input by pins 2 and 3. Accepts straight key input if the ring and tip are connected together at power up. |
