Furthermore, aftershattering an overhead fluorescent lamp in afilling station one night, with a cowl-mountedjob, the antenna was transferred to the rearbumper as the only safe place for an 8-ft. whip. The abilitj^ to QSY more than a few kilocycleson any band with such an arrangement was ahopeless dream, nursed in despair for a longtime. The usual procedure is to tune up beforethe car is put in motion, and then stop a coupleof times to adjust the antenna to compensatefor the change in capacitance as the wind bows♦Route 2, Box 42, Myssa, the whip backward. Wlien it is desired to QSY,the procedure must be repeated. (This sort ofstuff can lead to divorce if the XYL is alongexpecting an uninterrupted Sunday drive.) A Convenient Tuning System The remote tuner described has solved thisproblem well, and the author is now at peacewith himself and the familj^ No cross wordsfrom the XYL, even after miles of rag-chewingon 75 meters. The antenna is tuned by a variableinductor connected at the base of the antenna,and driven remotely from the drivers seat bymeans of a flexible shaft. The number of turnsneeded to cover the 75-meter band is so smallthat it has little effect on the performance ofa center-loaded antenna. Some commerciallymanufactured tuners, similar in principle, em-ploy reversible motors for rotating the a suitable motor and reduction gears areavailable, fine, but for economy and downrightsimplicity, the flexible shaft is hard to beat.
