!Rload checking the resistance * This is function is only for K9AY feeder with Variable Rload part. * There are two ways for fine tunning of Rload. * '''Please check some more info about Controller box of K9AY++ '''[on this link|https://qro.cz/remoteqth/wiki/index.php?page=K9AY+and+Bi-dir+beverage+controller#ANT_Rload_fine_tune] * Connect Ohm meter to this position and measure value vs input Rload VTL voltage - PIN 6 on RJ45 connector '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: Final Rload resistance may vary with the direction switching. This is caused by thin GND wire between controller and RF feeder box. If the changing is lower than 10 % than all is OK, if more, than more GND wires are recommended. Using CAT-5 FTP (shielded) cable can be big advantage in this problem.''' '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: For final tunning and measuring, please connect control cable as well also the coax one!'''
