Hi all, I have started using a IFR-1200S which has been lying around for a while. My issue is the power measurement via the T/R port reads low until it has warmed up for about 20 minutes. After that, it reads just fine. I'm testing using a 5W handheld radio. As a troubleshooting step, I set the frequency of the spectrum analyzer to the same frequency as the handheld radio, and there is approximately 10dB difference between the value I read when I just switched on, and the value I read when it's warmed up. This is reflected also in the power meter (approx 360 mW just switched on vs 4W when warmed up) Is this normal? If not (I assume not) any ideas on what I should be looking at to fix it? I figured I'd ask here before I go delving into the service manual. Thanks in advance!
