Re: HDHR5-4US can barely stay tuned to a channel

!!!!!!! NOoooooooooo !!!!!! you don't want anything lower to your modem... it was at -10 already where you want to be closer to 0 (look at power measured in dBmV (which many shorthand to dB) not SNR and you just reported worse on SNR which would be best around 40 though I find often can work down t...

Re: HDHR5-4US can barely stay tuned to a channel

I wasn't suggesting adding an amp but removing one if it existed. I was trying to come up with an explanation for the modem being at -10 when the signal should be fine at +10 tack on the attenuation you said you had it would be an even greater swing. An old amp or old splitter may have justified th...

Re: HDHR5-4US can barely stay tuned to a channel

Where are you attenuating as those numbers look terrible like you put it before the split rather than to device but it may be your cable system needs to adjust their higher frequency amp as 10-13 dBmV more would be perfect (note i don't expect those high frequencies to ever be up to perfect range b...

Re: HDHR5-4US can barely stay tuned to a channel

An fm trap or other high pass filter... the problem is that they can block some channels as well. What are the signal levels like on your modem as I find it hard to believe you need that much attenuation. I suggest turning on sending of diagnostics data and running a scan then post the time of it a...

Re: HDHR5-4US can barely stay tuned to a channel

The way i like to say it is that the later the generation, the more susceptible it is to overload so you will most likely have to attenuate the signal if it is strong. I would also suggest looking at filters for possible MoCA or LTE interference and since you seem to state upload causing issues pos...

HDHR5-4US can barely stay tuned to a channel

I'm hoping someone can provide some suggestions on what to do to make my HDHR5-4US and HDHR4-2US useable for clear QAM on my setup. I've been using a HDHR3-US for over 9 years now. This thing runs flawlessly for my intended purpose. I initially purchased the HDHR4-2US refurbished direct from silicon...
