I may need some assistance on how my P3 should act. My P3 arrived while I was away on an extended trip to the Northwest. I now have it up and running, but I have some questions. I've perused the manual, including the newer version on the website. It seems that my levels may be wrong, but not sure.
Here's what I have done--I updated my K3 firmware to the latest version on the website. I also updated the P3 firmware. I also had to make the mod to my K3 (#96) for the I.F. output gain. Prior to making that modification, the noise level seemed to be around -110 dbm, but that was also before I updated my K3 firmware also. Now, I seem to have a reference level way down to around -140 dbm. I do see signal spikes, but it seems to take an S8 or S9 signal to really show on my screen (to differentiate them from just noise), which I assume is indicative of my noise floor. None of the illustrations in the manual show something starting that low. It makes me wonder if I did the K3 mod properly. I did replace the SMT part with the supplied SMT device (or think I did!). Hopefully I didn't screw that up. All of this scaling varies from band to band somewhat, but it's always -120 dbm or lower. I see nice spikes from stronger signals, but some that are quite copiable on the K3 don't seem to make much of a spike at all. The waterfall does seem to show the signal better in those cases. I'm assuming it's just because those signals are right at the noise level, but I was primarily concerned about the fact that my setting has to be so much lower (higher numberical value of "minus" dbm) than anything shown in the manual.
