Yeah something isn't right. I just had a coax from the radio to the sampler, then dummy load screwed on sampler and then bnc connector to scope.

I know for a fact beyond a shadow of a doubt that the positive and negative wires were hooked up correctly. I have the power wires hooked up to my power supply and have never removed or changed them. I just simply plug the wire into the back of the radio I'm working on.

So what went wrong???? Check this out, I just had the radio power on, lights on dead keying 2 watts then i hook up to rf sampler and instantly starts smoking again. Lol what the hell. I will be damned if I attempt to hook up another radio, that would be the definition of insanity lol.

I have to radio on now and it's not smoking. I bet a 100 bucks if I hook it up to the sampler it will start smoking.

Nope defiantly hooked up right way. Protection diode is fine. Happened atleast three time when I hooked up the sampler. I would repair it check on meter then hook up to sampler and it would start smoking. The third time smoked it out beyond worth repairing.

Picture of sampler

So I got an rf sampler. Hooked it up to the radio, the other end to a 100 watt peak dummy load and bnc connector to scope. Turned on my radio and no power to radio. So I checked the radio and found a burnt trace and repaired it. I looked inside the sampler and everything was normal. I hooked...

Oh yeah, that's badass!

Yeah that link is the same holder I'm using. Does it make a difference what kind of 8 guage wire to run... like silver plated or just regular ol stranded hook up wire?

Yeah I looked at the pictures a few times. I didn't know it was a junction box.....thanks.

Good deal, thanks for the info. As in the metal, what material is used to bolt the BNC connector and pl connectors to?

10-4, thanks for the specifics. What kind of metal is used? Yeah I got a 100 watt dummy load. How much of a sample is generated into a scope with this setup?

Anybody ever hooked one of the lt-2n echo boards in a cobra? The directions are a little different then a trbx3 and br1. Can you soldered the the three black wires to ground pin and two white to audio pin? Thanks

Yeah 10-4, what kind of metal works best?

Also is the ferrite core wire soldered to the nut?

What components/values do I need to make a rf sampler box? I'm wanting to use it for cobra 29 ltds/ galaxy 959? Thanks for the help

Thanks rob!
