Added 4:45 pm & 25 C (77 F):
3860: 9.0 to 9.2 dB (varying, locked)
3900: 10.3 to 10.6 dB (varying, locked)
After 7 1/2 hours, I'm stopping. My sense is the former ice had no effect on SNR. I saw SNR drop through the day, lose lock on the main test tp and SNR is now beginning to rise again. I conclude there are more factors at play than just a warm LNB. Or perhaps a substantially colder LNB would be required.
