1. [TenTec] 229A SWR Circuit (score: 1): Author: Rick W <ve7tk@yahoo.ca>; Date: Sun, 1 Jul 2012 08:39:29 -0700 (PDT); I have recently acquired a 229A tuner. It needed a few repairs - mainly mechanical - but otherwise seems in good shape. I've replaced the dial elastic cord and it tunes smoothly and consistently.

Re: [TenTec] 229A SWR Circuit (score: 1): Author: Stuart Rohre <rohre@arlut.utexas.edu>; Date: Sun, 01 Jul 2012 17:49:57 -0500; Rick, The most likely failures of any SWR measuring circuit are 1) short of open of diodes 2) changes in carbon resistor values 3) Someone messing with, or a bad calibration pot 4) Finally, capacitor; /archives//html/TenTec/2012-07/msg00021.html (8,124 bytes)

Before doing anything else just change all of the diodes. They are cheap and avaiable. You won't damage any other parts such as the meter trying to trouble shoot the circuit an; /archives//html/TenTec/2012-07/msg00026.html (8,784 bytes)

Re: [TenTec] 229A SWR Circuit (score: 1): Author: Rick W <ve7tk@yahoo.ca>; Date: Sun, 1 Jul 2012 21:17:16 -0700 (PDT); Thanks Bill - As mentioned in an earlier post I had already replaced the diodes and the problem persisted. http://lists.contesting.com/_tentec/2012-07/msg00010.html I really think it's the 200 u; /archives//html/TenTec/2012-07/msg00027.html (8,955 bytes)

When the meter deflection falls short, are you using SSB or key-down CW? Phil C. Sr. k4dpk I am having a problem with the SWR / Power measurement circuitry.
