@Gregbadilla You can cut it off and put a new RJ-45 on. It will be shorter. Or you might be able to very carefully cut open the existing connector and extract the wires from the broken connector. I once did this for my 706 hand mic, but the RJ-45 wasn't as big as this one. I used Dremel tool

@F5rrsD Oh ok then maybe I remembered his call correctly. His QRZ profile has very little information. Thanks!

I made contact with a VE station on AO-7 earlier today. Something like VE3GK. I didn't have a recorder running. Any ideas what the actual call was?

We're going to set up/test our ARISS station at the school today. Might try a sat pass. Possibly AO-73 @ 19:53z More realistically: AO-7 @ 20:35z AO-73 @ 21:30z AO-7 @ 22:23z Grid FM05

We made contact to a VE station without the external preamps on. We figured out the right settings for the preamps in the 9700 after the pass. So our setup seems to be working really well!

@k5zm_ ... And that worked. I also had to adjust the pots on the CSN S.A.T. to get them between 4-5 volts.

@k5zm_ But I did get the CSN to control the antennas. Auto calibration of the rotator did not work. I mean it spun the antennas fully around but when I tried to track a sat nothing happened. I manually calibrated them by adjusting the output voltage on the rotator control box
