[Icom] Intermittent swr

Wed, 18 Dec 2002 00:26:45 -0500

I had a similar problem and did the following.  1)  I took the covers off 
the rig and make sure all of the boards were properly tighten (nothing 
found here).  2) I was having a problem with my installed filters not 
working properly or not at all.  I took each filter and reseated them.   I 
know this didn't have anything to do with what you described.  3)  I took 
apart my entire antenna.  I'm using a Comet UHV-6.  I cleaned every part 
that might have had a dirt film on it.  4) I reassembled the antenna and 
mounted back on the car.  5) I double checked and reseated the 1" braid 
grounding strap from the antenna to the car frame.

Sounds routine but corrected my problem.  Things load up without any 
problems and my SWRs are back to normal.

Wow. I'm stumped. I'm running an  IC 706 mkII g in my mini van with an 
outbacker stealth plus on a tri mag mount on top. Everything was hunky dory 
until all of a sudden my swr has been very intermittent. Up on minute down 
the next. I tune with rtty and one time it will show on swr then infinity. 
This has happend on both 80 and 40 and I haven't checked it on other bands 
yet but I suspect the same will happen. There seems to be something loose 
in the system. I removed the tuner from in line took off the spring and 
quick disconnect from the antenna and have checked all connections 
including the wander lead and stinger on the antenna. I can't seem to find 
anything wrong. It still is very intermittent and squirelly [ if that's a 
word]. Could there be something in the radio itself or am I just missing 
something extremely simple. This was not a problem until all of a sudden 
and I can't think of anything recent that could have happened to the 
system. Any suggestions or thoughts would be appreciated.
