My Insignia HD portable seems to be having problems with ALL HD3 channels lately. It's still fine on HD1's and HD2's, but ALL the HD3's are cutting in and out, and I'm just a few miles from the ones on the Pru. I wonder if it has gone out of whack inside because it's been dropped a couple of times?
Maybe Bob could visit you at your home and bring along his HD Radio. If the two receivers behaved the same on all of the HD-3 signals, you would not have proven that there is nothing wrong with your radio (or his), but you'd have pretty good reason to believe that there is nothing wrong. If the two radios behave substantially differently on the same signals, you'd have reason to believe (but still not proof) that the radio that provided the less reliable reception was defective.
I haven't tried another Insignia HD portable yet, but my two HD home radios, a Sangean component stereo tuner and an "iLuv" stereo table clock radio, have no problem receiving most of the local HD3 signals. The Sangean had a lot of trouble with WZLX 100.7 HD3 (my favorite HD3, "Free Form 'BCN") cutting out all the time a few months ago while it was fine on the "iLuv" in the same room, but I'm guessing CBS Boston must have tweaked something, because it's now also fine on the Sangean with only very occasional very brief dropouts, without any changes to receiver or antenna on my end. I'm only a few miles line-of-sight of the Pru, so there's plenty of signal strength, it's a matter of how the receiver detects and decodes the HD3.
One exception is 104.1 HD3, "Psychic Radio". Though 104.1 HD1 and HD2 are full-strength and steady on all radios from the Pru three miles away, 104.1 HD3 is non-existent on the Sangean (it won't even detect a 104.1 HD3 at all) and it only comes in as brief blips at best on the iLuv. Oddly, the Insignia portable does the best on 104.1 HD3, it gets it intermittently as it does all the other HD3's. I personally don't care to listen to "Psychic Radio" so it hasn't bothered me that my home radios don't get it, but I still don't understand the phenomenon.
At this time, both the Sangean and the iLuv do well on all of the other local HD3's, 89.7, 93.7, 98.5, 100.7 and 103.3. Only 104.1 HD3 is inaudible on those while its HD1 and HD2 pin the signal strength meters. The Insignia HD portable cuts in and out badly on all of the HD3's, even when it's just sitting on a table, regardless of whether I'm moving it around. Because it's become so much worse just recently, I suspect something happened to it from being dropped, but whatever happened only affects its reception of HD3's. HD1's and HD2's are still fine on it. I guess I'll have to buy a new one.
I also noticed that if I put the Insignia FM HD portable near an AM radio, the LCD display of the Insignia creates horrendous interference across the entire AM band within at least a foot of it. It actually wipes out reception of all but the strongest local AM stations when the Insignia is next to the AM radio, and the interference disappears when the LCD display of the Insignia turns off. No wonder the Insignia is FM-only with no AM section, I don't know if they could possibly internally ground out that much AM band interference from its own LCD display.
