Good morning Just got my DMR radio HT programmed last night.  Was listening to my net and I wanted to see if I can hit the repeater.  Here is where it gets crazy.  When I key it up (HT) the 6600M freezes. Latest software.   Any Ideas.

RF is getting into your rig or computer (best bet it's the computer). Easiest solution is to put some distance between your DMR rig and computer.  Antennas away from radios, good grounding, ferrites, high quality shielded cables, wireless mouse and keyboard all will help with EMI issues.

And if you are not using a computer, choke the Ethernet cable and the power into the radio.

Thanks Got ferrites on almost every cable.  Power cable. cat 6 cables, antenna connects and so on.  Small room here for a shack so moving the HT away is kind of hopeless.  may just turn off the flex when I am talking on the HT.

Check SWR on your HT

That is a new one for me.

But I DID have a Vista Pyramid power supply that would go funky when I was on 2 meters.  Sometimes the voltage would go weird.  Usually the crowbar protection would activate and shut everything down....

Could your HT be causing voltage problems in your PS that are freezing the rig?

Check it methodically. Disconnect everything
from the radio and key the HT. Then add one
thing, such as the antenna next to see if it
is OK. Keep adding till it freezes. Process of
elimination.
