Helmut,
Try http://www.vcnet.com/measures/
When you get there, take a look at Figure 23. That bandswitch wafer came
from one of my TL-922s before modifying the amp - very stable now after
making the mods.
I have modified several TL-922s using Rich's redesign. However, I prefer to
mount the vacuum relay and reed relay (antenna T/R changeover) on a small
circuit board mounted over the hole vacated by the old bias changeover relay
(located between the rf-in and rf-out connectors). If you mount the vacuum
relay with silicon glue (ala Rich's suggestion) you will NOT hear the amp
switch.

Subject: [AMPS] S: TL922 Improvements
Hi again.
In one of the articles a while ago there was a website
mentioned with improvements for the TL922. I can't
find it anymore. If someone knows the URL please
send it one mor time.
I started to collect all the tip's and improvements from
my TL922 blow - but I want to have it more complete.
Thanks and 73sss
