Pi 5 with TV Hat Tuner

    Quote from boragthung

    What is the current situation using the TVHat with rpi5? There have been problems but I am not sure if they are now resolved or still troublesome.

    I'm not sure if you are having the same problems as me but I have noticed the tv picture quality has degraded quite badly recently.

    I've been using the Raspberry Pi TV HAT on a Rpi5 for about a year and it had been great - sharing live tv and recordings over 3 tvs.

    However over the last month or so (? since I haven't been using it much over the summer) I cannot get a watchable signal on any channel. All connections have remained the same for a year and currently running Tvheadend Server 4.3 version 12.80.3.3 + Tvheadend HTSP Client version 22.7.1.1.
    Tvheadend browser shows a SNR of 28dB and signal strength of -58dBm for a typical channel - I don't know what these values were when the picture was good so I'm unsure if they are now too low for an acceptable picture.
    As a comparison, my main tv that runs off the same coax from the aerial (via a "Y" connector - I know this is not the best arrangement but it's the same as when the picture was good) shows a signal strength of 90% and signal quality of 100%. I've tried running the aerial coax straight to the TV HAT but the SNR remains the same and signal strength changes by about 1dBm

    Any idea to fix this would be appreciated.

    p.s. running LE13 latest nightly on the Rpi5
