I am letting the D* installer into my next door neighbors(he is away) house for a new HD single receiver install. I am only familiar with HR20's and not the H series tuners, so I would like to verify a couple of things. 103c and 99c become 103b and 99a on the H21/23, I believe. I know what the signal strengths should be, mine are peaked very well, do the H series tuners indicate close to the same number values? For instance our local HD come from 99s TP15 and my HR20 indicates 99, should the H21/23 read the same number value? I remember they are slow to some up when testing. I want to ensure he has no trouble with his new system, I referred him Thanks for helping an old guy out.
