[TenTec] Titan 425 insight needed

[DennisKT5D at aol.com]

  What does your antenna VSWR through the amp (amp out of the circuit) look 
like? It has probably changed with the added lenght of coaxial cable from your 
exciter to the amp. I have a 425 and initially had VSWR problems on 40 and 20 
until I played with the length of the cable from the exciter to the amp. After 
a few tries I found that for my amp a length of about three feet of RG 8 
brought the VSWR back to below 2:1 on all bands. A subsequent discussion with Ten 
Tec confirmed that this approach was indeed their recommendation as well. 
  As for the noisy fan, fortunately I have a later model amp with the two 
speed fan and it isn't a problem. The down side is the fan is no longer available 
so I do regular maintenance on mine. Band switch sections and the vacuum 
relay replacements are still available but cost are outta sight. The Titan is 
going to be one expensive beast to keep going if age mortality becomes a factor.
