Thanks Rob! I downloaded the M201 manual today. I missed the TX PA diode detector but, now you mention it, I really should not have.

In my days as a Student Engineer they sent me on a programme of time in the various production departments. They didn't care much about the order in which you did things.

I went first to mobile test where M201s were the thing of the day. This one has crap TX modulation, change the PA, now it passes. I rejected a good number of them.

A few months later I got sent to module test. Ah, well here we are, some of my own rejects. Pass, Pass, Pass etc, just as the previous bloke in my seat must have found. But their tickets show they have been through here time and again... I wasn't happy.

I knew these were rubbish when put in sets so why? That's when I realised they had no test on the detector and the diodes HP5082-2800 were blown.

It got me a trip upstairs of Site 1 to the mobile lab to say - er... I think you have an issue with your test spec.

I had completely forgotten this. I still like the technique
