DESCRIPTION - The D-Lay-5 by Lance Johnson Engineering is a Rotor Brake Delay Circuit that inserts a 5-Second Delay (5.0 ± 0.5 Seconds) into the Brake Circuit of the popular C.D.E. or later Telex Hy-Gain Rotors:

·---- Ham-II ·---- Ham-III ·---- Ham-IV ·---- Tailtwister ----- SORRY: Not for the Ham-M Models!

The Installation (typically 15 minutes) requires the mounting of the fully assembled D-Lay-5 Circuit Board in existing holes (Meter Transformer) of the Rotor Control Box and then soldering four color coded wires.

Detailed instructions are included with each fully assembled and tested D-Lay-5 ; that was reviewed in QST Magazine in April of 1983.

HISTORY - The D-Lay-5 was developed by Larry Mills, WBØUXI, of Oak Grove, Missouri in 1978 and first marketed by Lance Johnson Engineering in 1979. The original prototypes were used at Kansas City DX Club Contest stations KØCS and ABØI to reduce rotor maintenance caused by exhausted guest operators. The Larry Mills design was brilliant because the D-Lay-5 doesn't require any modification to the Rotor Control Box. Just mount the Circuit Board using existing Meter Transformer holes and then solder four wires to points on the switches.

THEORY - The theory of the D-Lay-5 is simple. Once the user activates the rotor brake and begins rotor rotation-the brake will not engage until approximately 5 seconds after rotation is stopped. This eliminates the tendency of engaging the brake while the rotor is in motion-which is not good for the rotor's brake mechanism.

QUALITY - The D-Lay-5 is made with overkill in mind. The only failure mode we have encountered (since 1979) is due to thunderstorm induced voltage spikes that fry the devices two 1N5408 diodes (3 Amp-1000V). Customers still benefit when this happens, as the D-Lay-5 becomes a "fuse" for the rotor control's expensive meter. Lance Johnson Engineering recommends 8-Conductor Jones Type Connectors be used to disconnect the Rotor during thunderstorms.

TESTING - The D-Lay-5 has been manufactured and tested in Kansas City, Kansas by Mike Crabtree, ABØX, for almost 20 years. Each unit has the measured delay time marked on the relay as verification that the unit was functioning properly before shipment.
