[TowerTalk] Cushcraft XM-240 problem

[Steve Baughn]

Thanks Russ and Mike,

I don't like to put all my eggs in the MFJ basket but have to say the rig 
here (FT1000D) and RF applications wattmeter basically confirmed what the 
259b said. I think the next step is to rotate the boom 90 degrees and see if 
that makes any difference. After that I may drop the TH-11 since it is 
easier to get to and see again if the results change..I am only using 1 
feedline and have checked it forwards and backwards. Will report back when I 
get this figured out

73,
Steve, WD8NPL

Steve,  I was having similar problems in which logic was no help and it 
turned out that my MFJ antenna analyzer was bad.  Since then my bread and 
butter analyzer is the iPortable iP60z.  I now have 2 analyzers and it has 
saved me a lot of time for sure.

Also once when I was really stumped it turned out that I had fried my coax 
switching relay.  After that I use single coax runs exclusively.  Both 
problems produced weird resonance dips.  These problems shouldn't have been 
that hard to figure out but I made it a real circus by trusting bad 
equipment.  Hopefully you have been able to verify your test equipment and 
they are good.  Sorry if my reply is too simplistic....  Russ     K5ZZR   My
