With a Thunderbird, assuming proper assembly, your actual SWR should be very low. Your 238 should be in bypass, with the Z knob straight up and the tuner out of; /archives//html/TenTec/2002-10/msg00513.html (9,065 bytes)

First check the power Supply voltage. It is adjustable with a pot on the chassis. Make sure it is not set too high. I also believe; /archives//html/TenTec/2002-10/msg00514.html (9,844 bytes)

(score: 1): Author: n4py@qvssoftware.com (N4PY); Date: Fri, 25 Oct 2002 12:11:14 -0400; It sounds to me like your internal pot for the ALC is set too high in OMNI VI. I don't remember where this pot is, but there is an adjustment to automatically reduce the drive to the 100 watt level.; /archives//html/TenTec/2002-10/msg00515.html (11,504 bytes)

(score: 1): Author: rohre@arlut.utexas.edu (Stuart Rohre); Date: Fri, 25 Oct 2002 14:09:34 -0500; Please all, read Maxwell's book "Reflections" (either I or II) or the same QST pieces reprinted on the QST web site. SWR is RE REFLECTED from the tank circuit, (if no tuner) and does NOT enter the fi; /archives//html/TenTec/2002-10/msg00518.html (7,946 bytes)

IF you are getting more than the 80 watts of so most report as normal Output, adjust the rig to proper drive level. It cou; /archives//html/TenTec/2002-10/msg00519.html (8,016 bytes)

(score: 1): Author: AC5E@aol.com (AC5E@aol.com); Date: Fri, 25 Oct 2002 16:24:09 EDT; Stuart: Walt is perfectly correct as long as we are talking about TUBE circuits. Tubes represent a severe mismatch to reflected RF, with only the essentially trivial losses in the tank circuit keepin; /archives//html/TenTec/2002-10/msg00520.html (9,491 bytes)
8. [TenTec] Power Power Power - revisited.. (score: 1): Author: n4py@earthlink.net (Carl Moreschi); Date: Fri, 25 Oct 2002 21:17:01 -0000; Back EMF in an audio speaker is not analgous to SWR. Back EMF is a very real voltage being generated from the physical motion of the speaker cone causing the speaker coil to actually become a generat; /archives//html/TenTec/2002-10/msg00522.html (10,803 bytes)

Without going into the operating model of the transistor you assumed, even with some current leakage in the "cut off" state, yo; /archives//html/TenTec/2002-10/msg00524.html (9,294 bytes)

I fear you are getting old, young man. An experiment to prove or disprove my statements is; /archives//html/TenTec/2002-10/msg00525.html (8,651 bytes)
