Hi Ron,<br>

5.850 +6 dBm<br>

Anyone on the list working with the Lime LMS8001a Companion Board? Mine finally arrived and I'm starting to work with it. So far 10 GHz TX/RX is working (10.368 GHz). 10 MHz lock works well.<br>
<br>
Next is to try 5 GHz.<br>
<br>
At this point, no real measurements - just seeing signals going in/out and learning the setup.<br>
<br>
After initial sectional tests, I want to set it up as 5 GHz TX and 10 GHz receive.<br>
