This modification changes the AGC to a hang-type and uses very few parts. It retains the fast attack characteristic. The signal causes the meter to hang, ft returns to full gain quickly, about one and a half seconds after the signal is gone. The time constant of the hang-time allows the AGC to follow stow variations (OS8) in signal level. After this modificationt you need to repeak T5.

If your hunting antenna has the wrong polarization, ihe directly propagaied signal will appear to be much weaker. Worse yet, reflected signals from terrain features can appear stronger relative to the direct signal, resulting in false bearings. Unless hunt rules restrict the hider to a specific...

T-Hunters take note Here's a simple project that gives you a highly directional gain VHF RDF antenna. The TEY Quad antenna has no capacitance or inductive matching networks. Matching networks cut down the efficiency of the antenna by adding more electrical components into the RF line. Major physical distinctions of this quad design from other designs are 1. The Bazooka bafun an RF choke . 2. The diamond shape, which is sturdy and easy to construct. 3. The use of discarded TV antennas. 4....
