Well the jumper is still in place and it's not smoking. And I checked for continuity and it's working. Maybe 24 volts of DC on the scopes chassis might be the answer.

There is continutiy and those are grounds so it makes no difference.

And I had the radio the radio running multiple times and when I would hook up to the scope it would start smoking. Did you read through the posts and see if got 24 volts DC on the chassis of the scope.

No I have the radio on now, nice try.

24 volts DC on scopes front cover when I touch ground on power supply to front plate cover on scope.... what's the diagnosis besides being a little on the dangerous side lol.

So with the scope on I got 24 volts DC on the front frame when I touch my multimeter meter from ground to front plate cover! Even with scope off I got 24 volts. I unplug scope, drops to zero. What the hell

I plugged into the gfci and it didn't trip...

Yeah I bought the tester and in my garage where I do my work all but one socket was open ground. I plugged my equipment into the good socket and with scope connected it smoked my radio out. I concluded it's the scope. I got my radio to light up now and I have no hash in my speaker. I removed the...

So I have concluded it has to be the scope. I have an old tektronix 465b. I hooked up to good wall supply. Fixed the burnt out radio it was running and lights working. Hooked up to scope through rf sampler and guess what????? Smoke starting billowing out. Something is seriously f-ed up with the...

I tested the wall outlets in my garage and all of them except one tested open ground. So did the open ground Fry my radio?????

If I had my scope on the wrong Settings could that smoke my radio?

I got 60 volts from ground to neutral on Wall socket. Might be phantom volts. Getting wall tester now.

Yeah I tested the sock and I'm getting 60 Volts ac on ground to ground. Any idea how to fix this?

From chassis on scope to radio I got 11.4 volts ac

The 11.4 volts is with the positive lead on the screw and the negative on the radio chassi

So the scope has three prongs. With scope, power supply and radio on ( radio doesn't light up anymore. From screw on Wall socket to scope I got 2.3 v ac, from screw to radio I got fluctuating from 36 v ac to ol and 11.4 volts DC. Is that normal?

The way I had it set up was coax from radio to rf sampler, then dummy load screwed right on to sampler then bnc wire to scope. I didn't have a meter hooked up.

10-4 I will check it out and get back to you. I still don't get why it wasn't smoking when it wasn't connected to sampler. You would think it would smoke whether it was connected to the sampler or not and it only smoked connected to sampler...... process of elimination.

I know when I screwed the coax onto the sampler I saw a blue spark...
