Chris.SE:

Thank you very much for your suggestions. Timing couldn't be worse as I'm just about to go away for 10 days and had quite a few recordings scheduled. The offending device is a Humax HDR FOX-T2 PVR. Weirdly, my HDHomeRun tuners that run off the same aerial, albeit from a different outlet and with a signal booster, have picked up the changes after a few rescans and I can record off those (eg 101 is represented through tt8qam256:594MHz-17540, which suggest channel 36, ie the new one).

I guess I need to look into a new Group K aerial and/or an extra signal booster when I get back. Thanks for your help.

When I moved to Southwater in 2015 the TV reception was very flaky and got worse when it rained but eventually I got a wideband aerial installed which improved things a lot but it was still at times flaky and would be bad when it rained. When the first phase of the 700Mhz happened and I retuned I instantly noticed an improvement for the channels and when it rained the reception did not drop for the muxes that had moved over to the new channels. The channels that remained on the 700Mhz range though were still affected with bad weather. Now that the remaining channels have been moved out of the 700Mhz range all my channels work absolutely fine in bad weather. Not sure what was causing the reception to drop in bad weather but a result for me!

Charles:

The lower frequency channels will tend to travel a greater distance for the same power so you tend in general to get them with slightly higher strength, so when that is reduced by rain, it doesn't drop to a point where your signal is on the "cliff-edge" and pictures start pixelating.

You maybe in a slightly marginal location, if you give a full postcode we'll be able to make constructive comment on that by examining your predicted reception give by the DigitalUK checker About us | Freeview

That is good to know and I have read (not sure if true) that when trees get wet then this can affect the signal. Now when I observe the signal quality and strength it holds strong when there is rain where as before you would gradually see it degrade to the point of no signal coming through.

Anything that is in the "line-of-sight" to the transmitter could affect the signal. If you have trees in the way, they can indeed affect the signal, especially when wet.

Hi
Since the update of Freeview October 19, I,m now only receiving 9 channels, (one being ITV. Has the signal strength from the Mudhurst transmitter been reduced in any way?

Mark Hulme : There has been no reduction in broadcast power for any services at Midhurst, however if you have an older Group C/D aerial it is no longer suitable to receive all of the frequencies now being used. If you don't have satellite or cable, the Freeview Advice Line (see link below) can arrange for a replacement wideband aerial to be fitted free of charge.

Mark Hulme :

Did you not lose any channels with the March 2018 retune? I find it strange that you mention you are getting ITV, are you not getting any BBC channels?

The transmitter power has not changed. What has changed is the UHF channels that the multiplexes are broadcast on as a result of the What is 700MHz clearance? | Freeview (click on link).

The channels Midhurst used to broadcast on were in aerial group C/D - the top of the UHF band. They have now moved to the bottom of the band (except the main BBCA muliplex which is still just a the lower end of the C/D group. The suspicion is that you have an old C/D group aerial which will not pick up all the new multiplex UHF channels satisfactorily, you now need a Group K aerial for Midhurst.

Now, there is the possibility that you are in a slightly marginal reception area, but only with a full postcode can we offer any constructive advice on that, this could make matters worse if you have an old aerial.

Did the retune messages on screen not give information on what to do if you lost channels?
Now providing you don't have Satellite or Cable TV you can get free help by contacting the Freeview Advice line on 0808-100-0288 where they should be offering to send an engineer to replace your aerial with a Group K.

If your aerial has already been replaced, you'll need to provide that full postcode and further detail about your installation for us to provide constructive advice.

Following the Midhurst retune 16 Oct 2019 (several times!) the BBC ch 48 is fine as indeed it was before however ITVs etc ch 33 34 35 36 are terrible signal strength is 100% but quality is terrible one minute 100% then up and down to 5% the 30%. then ok for a few hours
No reason it can happen any time of day or any weather condition BBC remains 100/100% through out
Have disconnected any PVR that might have produce any rf out at or around those channels ...no change
All was fine before retune use about door Hi gain Wideband aerial 2 years old with an LTE compatible distribution amp with compatible masthead amp and a 4g filter
Any ideas
