HDHR4-2DT Where are my HD channels?

Post by Dan77 » Sat Feb 22, 2020 2:04 pm

Anyone got any good ideas on how to get HD channels? It's detected 131 channels but not a single HD channel. Below is what I expected to get as these are available on my Samsung TV. According to the diagnostics on my TV I have a decent signal strength (96/100) I asusme that's good?

101 BBC One HD PSB3
102 BBC Two HD PSB3
104 Channel 4 HD PSB3
105 BBC Three HD PSB3
106 BBC Four HD COM7

There are a number of things that can cause your issue... first is too much signal as i wasn't sure if that figure came from the hdhr or the tv though i doubt that is the issue when reporting 96%

Next is the issue that will be that the device (scan) will only allow one of any virtual channel number... what gets added when there are conflicts is the one with the highest resolution, and then by signal quality. If that is the issue 3rd party software that allows adding channels based on physical rather than virtual channel number must be used. (channel gets added by physical but depending on software may look to be using virtual.

Also in the uk, many find they need a filter (braid breaker).

I suggest turning on sending of diagnostic data, running a channel scan and reply with your deviceID so the folks at sd can take a look.

You have a fairly poor signal on the BBC B (HD) mux so that is coming and going from one scan to the next. The COM7 and COM8 muxes on your transmitter are only sent at about 40% of the power of the main 6 muxes so they are quite weak and aren't able to lock at all. What kind of aerial are you using and what is the cable/amplifier/splitter layout?
