RFX-75

So I checked my SWR on a external meter (a Zetagi meter). It's saying my SWR is in the higher range where it is not suppose to be. So the antenna light is functioning correctly. I am gonna go get a coax for single antenna try to calibrate then separately then hook them back to co-phase.

Now I am wondering. Why was my setup fine before I had the RFX installed. Now it's not calibrating. Would the rfx require me to adjust my antenna heights. Also would feeding the power with the cigarette lighter cause a antenna problem. I know it affects some RF noise in the speaker but as for the antennas does it affect them at all. I will be probably run the power and ground under the dash to the power block.

Any help?

 

What would cause my SWR to calibrate correctly then talk for a bit then check it again and it's back up in the higher range on the meter??

Also my antenna light only comes on when I speak into it and sometimes it doesn't come on at all. This is just during testing. I am not using the radio until I figure out what is happening.

I went to radio shop and he says the RFX has nothing to do with my antennas. So why all of a sudden would I have this issue. Again I haven't changed my antennas and everything was fine before.SWR stayed at 1-1.5.

Also when I calibrate at 1 then go to 40 and then shoot back to come the meter is no longer at the arrow where you move the needle to calibrate. Is it suppose to do this after calibrating at channel 40??


Any thoughts???

 

I use a RG59. It's a proper co-phase.

The cable on passenger side was pinched in door which might have caused it. Seems to be holding a good swr now.

Still have the problem when I talk the antenna light comes on. Dead key it does not come. If there was a problem with antennas shouldn't the antenna light come on with a dead key as well!?

I just don't wanna destroy my radio. I am unsure if the light is only coming on because of the added power.

 

I noticed when I was on a radio station with static that mu talk back comes through the fm radio.

Why is this??

 

Could it be that the antenna light is coming on because of to much power and the light needs to be calibrated for the extra power?? Is this possible??

I mean I am running co-phase wilson's that should be good for the power correct??

As for the radio stuff... yeah it only seems to do it when I am on a station with more static then music/talk show on it.... When I am on a station that has constant talk or music I dont notice it happen.. although it does seem like it's lowering the sound level from the speakers down..

 

Well I think they adjust pots and such when installing the RFX.... So I am leaning more towards the extra power is causing the light to come on and not a problem with my antenna's.. Like I said prior to RFX the antenna light never came on and I haven't changed a single thing with my antenna setup... Since the antenna's are match with the truck and not the radio I guess that means the match on the antenna's shouldn't change just because the radio is putting out more power...

Now my lights on my radio dim when I key up.. I know this is caused by the extra power... Now is this because it's hooked up to the cig lighter or just the way it goes when you at the RFX.... Some people are saying the cig light socket is 20amps.. That should be enough for the radio right?? Since my 12ga wire has a 10amp fuse for power and 5amp for ground wire..
