HR21-100's tend to show lower signal strengths by around 10 points on 99 and 103 than other HR's. Watch for this to change on the next national software update.Mainea said:My 99 on my 21-100 was in the 70 - 80 range after install. I tried to "peak" the signal and could only squeeze out a couple more points higher. My 103 is generally 70-90 with most in the mid 80's. These numbers look much hight on my h23. Can a tech get these higher or am I peaked??
