!!Setting step by step ** Connect TRX (PA) to the 4SQ-8DIR hybrid - to Input port ** Connect Dummy load to the Dummy Load port ( you can insert PWR meter too ) ** DO NOT connect any antenna element - leave it open ** Than when you TX (RTTY mode) all power goes to the dummy load port ** Connect controller box and open it ** There is SET SWR trimmer (blue one) ** With this trimmer you can set full range of LED bar for prefered MAX power in dummy load [https://remoteqth.com/img/ZAW-WIKI/4sq-8dir/vyrez_led pasek.png|noborder] '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: Do not forget thar SWR 2:1 on antenna elements is 1/10 of INPUT power to dummy load!! So for 1kW and SWR 2:1 is 100W in DL. There is no problem to have only a few Watts in DL when the antenna elements are right tuned!''' ** So set TRX power to your max PWR you want have in dummy load and set SET SWR trimmer to full LED bar range ** When LAST red LED is on, than PTT loop is disconnected * see jumpers setting '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: When you set full scale for some PWR, for example 200W. Than you can go down with PWR from your TRX and you can see what PWR = LED COUNT. What is half of scale, first LED etc.'''
