I can't seem to get the SWR to move at all. I have it at 100% on the adjustment and can only get about 1/2 way in the red, around 2.5 maybe, then when i switch to REF it goes to the 1, but doesn't move on the meter. If i key it and let off it never moves. I have checked the meter on other installations and it works. All my radios are showing to have around .5 to 1 watt of power with this configuration also, and modulaiton is low also, 60% or less. This is a new installation, coax, antenna, etc. Firestik 4' and 18' cable. What can be wrong? Thanks.
