hi guys .I have the above diplexer in use but it was tuned to 76mhz and we have it retuned according to the manual and it is in use at 78mhz but the swr from the tx814 is reading 3 to 1 on my meter and it was turning the vswr circuit on and very little power was being transmittered .I tried a shorter length of rg223 in the tx diplexer path with a higher swr and it activated the alarm so it looks like i will need to increase my cable length .would it make any improvements to adjust the tuning loops.ie shorten them a bit or is is better to try different lengths of cable to lower the swr and dont modify the loops .thanks ian
