Okay I should know this, but my mind is getting foggy. I have just put up a couple of MFJ 1777 Doublet antennas. One is pointing north-south, one east-west. I have the proper MFJ W9INN Balun boxes , one for each antenna connected. I connect them to my Collins R-388 and I can hear everyone, left coast,(I am in Alabama) Canada, you name it. I got out my my Kenwood 520S SSB radio just to have a conversation with a good friend, the radio connects to my Heath kit 2040 antenna tuner, and I get absolutely nothing into the BIRD 43 meter. Without it, I am putting 120 watts in (CW), but reflecting goes to the peg. I realize I need a tuner with these antennas so I connected it in the circuit: radio to tuner to Bird to antenna. Nothing. What am I doing wrong? (Besides using side band - of course)
Try the following routing:
Radio --> Bird --> Tuner then Antenna feeder...
Tune in CW mode, power reduced, to show initial low level reflected power on Bird. Then adjust Tuner for minimum reflected power.
Then set Bird for forward and increase output power and peak for maximum output...
If you are going to use CW or SSB you are all set...
For AM, set your forward output power to 1/4 of the peak reading on the Bird for AM to allow "head-room" for the AM and avoid carrier shift at 100% modulation...
