    The HR20 is a great machine in many regards. However, the OTA tuner is very weak in my opinion based upon using other OTA tuners on other equipment using the same antenna setup. Can the HR20 tuner be improved through software updates or is this a hardware issue? Additionally, is there a diffrence in the tuning ability between the HR20-700 and the HR20-100. I am looking forward to some lively discussion regarding this issue.

    OTA tuner works great for me with a big CM and pre-amp.

    For some time Earl had relayed to us that the hardware could not receive Low VHF, channels 2-6.

    Then one day, it could.

    So what else could they do in software with the HR20's OTA tuners?

    I don't know.

    There is a fundemental problem with the HR20 using what appears to be a passive internal splitter between the two tuners. It seems it causes the 3 dB loss that you would expect when compared to boxes like the H20 that do not split the signal.

    I bet that there is more that could be done.

    When did I ever state it was definitively hardware?

    I know a lot of people theorized that it was hardware, but I don't recall ever stating it was hardware..

    As to the OP's question.

    While I am certain there are probably some minor things that can be improved via software... in general the hardware is what the hardware is.

    I just got a HR20-100S installed yesterday and my opinion is that it's OTA tuners are better than my HR10's were. Just my $.02.

    Indy - They're a LOT better than the HR10.

    That's a relief. Hopefully it will pull in the HD locals that I don't get from D* without a problem.

    it stinks in my opinion, when i hook it up to my Samsung plasma vs the HR20 its like night and day it drives me crazy, and the funny thing is i have bought several versions of amplified antennas and my old non amplified antenna works better then the amplified

    I just upgraded to HR20 over the weekend and have not hooked up OTA, which I will do tonight. How is it a "LOT better" than the HR10? Just curious...

    For me, I went from 60-70's on the HR10 to 80-90's on the HR20.

    Lancaster,...
    How would we know if the HR20's OTA (ATSC) tuners can be improved unless we designed the HR20s? I would hope the ATSC tuners can be improved, but the avg person probably has no idea if this can be fixed through software or not. In other words, I don't think the question is subjective.

    I voted yes based on the fact that my OTA performance deteriorated with the 15c upgrade a few weeks back. Though the poor performance - audio and video drop outs every few minutes - was on playback of a recorded show, so maybe the dvr software was to blame. Nary an issue with the H20 that it replaced.

    Don't know if it can be inmproved a lot through software. I'm a big fan of the hr20 and both of mine have never given me any problems but I do have to say the Sony tv does a better job with the OTA.

    I kept my HR10 as well...so I'm gonna spot check the signal strength on my HR10, then hook up the HR20 and compare the signal strength. I live 40 miles out of Chicago so I have the large multidirectional OTA antennas, so I get CBS-Chicago which is on a VHF band. I have no problems getting it on my HR10. I'll test it out tonight and report results tomorrow if anyone is interested.

    For me, my NBC channel was in the 40s on the HR10 and also breaking up. Hooked up HR20-100 to same antenna with same wire and now it comes in much better. Signal is still lower than my other OTAs, but breakups are much less frequent. But fortunately for me, I know get my local NBC in HD via sat.

    Also, somewhere I read the signal meters on the HR10 vs the HR20 aren't a direct correlation, meaning a 40 on the HR10 and a 40 on the HR20 don't mean the same thing. Not sure of the reason behind that, but just because your numbers on the HR20 are vastly higher doesn't necessarily mean the HR20 tuners are that much better. Signal strength of 10 or 90 - I don't care as long as the channel doesn't break up.

    A couple of my two cents:
    Large antennas usually mean directional [so unless you have more than one it's not "multi"].
    Signal strength readings on the HR-20, aren't, but it does show "bit error rate" [not RF power].

    Lower...
    It's a bit over my head, but for those who are interested, it looks like there's a good explanation of how bit error rate is measured and calculated about halfway down this page: http://www.sencore.com/newsletter/Nov03/HDTV_files/HDTV.htm /s

    If you can understand that, you wouldn't be asking questions here, but would be answering them..:lol:
