Hi Ron, You do need the P3 utility to update the P3 and the K3 Utility should not be running as they use the same serial port.
If you are seeing No Sub you probably don't have the Config menu KRX3 set to ATU or BNC. Which of those you chose depends on how you have the sub receiver installed. Choose ATU if the sub receiver antenna is connected to the ATU or BNC if it is connected to the AUX BNC connector. 73, Fred KE7X For all KE7X Elecraft books, see www.ke7x.com<http://www.ke7x.com> ________________________________ From: Elecraft <[email protected]> on behalf of Ron Wilcox <[email protected]> Sent: Tuesday, October 25, 2016 12:35 PM To: [email protected] Subject: [Elecraft] P3 utility and no sub receiver First time poster. I just finished putting together my K3S, subreceiver, 100 watt amplifier and panadapter. Having a medical background this was quite a unique experience. I have a couple of questions and could not find the answer in the archives so hope this is not a frequently asked question. I have read the sections in the books multiple times but it is still not clear to me. My computer setup is via USB. 1- I was able to update the K3S and access the utility with no problems. I cannot update the P3 or access the P3 utility when the K3S is on, and am running the P3 from the K3S. Is the P3 automatically updated when I do the K3S? Do I need the P3 utility when the K3S utility is linked to my K3S? 2- When I push the "sub" button I get "no sub", what is my next step, or what did I miss? Thanks in advance.
