I received my v9.0 Lite+USB Xtall kit with the Si570 and the Electronically
Switched BPF a couple days ago and want to dive right into it. With that dream
aside, I have been studying the assembly documentation and researching the
technology before touching the kit.
I have a couple questions.
1. What precautionary measures are people using to prevent ESD damage?
2. Since I've been out of the hobby a long time, I only have a DVM as test
equipment. Will I be able to get by withhout anything else?
I love the post reading, full of interesting info. Thank you in advance.

There is a simple solution to a lot of the ESD worries that most people don't think about. Raise the humidity in the room where you're working. Put a pot of...

Hi Don, Not too sure what you are trying to do, or what SDR program you are running. Never seen any 'carrier level' adjustment in any program as far as I can...
