I also receive from penyard relay transmitter and i'm also very angry that we can only get a fraction of the available channels. my parents at great expence upgraded their aerial etc to pick up from wenvoe and received nearly all channels available until the retune this month and now they can only receive the same channels as we get from penyard. how strange, i smell a rat don't you.

stuart: You have not provided a postcode, so I can't really say, but don't get upset, the commercial operators did not regard this transmitter as profitable to operate from because the costs of transmission would be large compared to the number of viewers.

Hi Briantist, my parents post code is Merthyr cf47 otl and they have been receiving all free view channels for approx. Three years even when Wenvoe was transmitting at half power. When switch over occurred in 2010 they lost film four, then later on they lost the Yesterday channel. They are using two separate aerial setups for two TVs, both setups have 12db to 15db wideband aerials and 22db mast amps. They have no video rec, skybox or games consoles attached, also neighbours with similar setups have lost the same channels and its only since the retune this month.com 4,5 and 6 have vanished, can you help

Stuart: The problem is that the final channel allocations for Wenvoe COM multiplexes clash with the allocations for the PSB multiplexes at Trefechan. The change to the final channels for SDN and ArqA multiplexes happened on the 27th of April. The ArqB multiplex moved at switchover at the end of March 2010.
You could see how well it works without the amplifiers first. The COM multiplexes are now in adjacent channels to the PSB multiplexes, and if the signal levels are too high it causes intermodulation, which causes errors in other channels but the worst errors occur in adjacent channels.
Otherwise, there's really nothing you can do without spending a lot of money on an antenna array that rejects more signal from Trefechan, or getting a satellite subscription. Freesat doesn't carry many of the channels carried by the Freeview COM multiplexes.

Hi Mike,
Not sure if the same guy or someone else phoned me yesterday with the same problem. I gave him exactly the same answer as you gave on this thread, this is a common problem here as every local transmitter is psb only & many people have invested in wenvoe rigs that have worked very well for years but now have these problems.
Im looking into aerial specs for a group B high gain very directional aerial with a very good front to back ratio to fit in future & to cure some existing installs. Thankfully I havent had any calls on our own installs but we align with rover meter / spectrum analizer rather than just point in the general direction like some do ! that may well make the difference.

Mark Aberfan Aerials: This will happen in the "final configuration" for quite a few areas, because the COM allocations use "gaps" in the PSB allocations, as did the pre-switchover Freeview transmissions in the analogue plan.
That is, of course, because the 3/4 of the only analogue plan is the new digital plan, for most sites.

CF47 9PF. Still have less channels than anywhere else. Upgraded aerial due to change over. My aerial is on the roof pointing towards Penyard. We were one of the first areas to go digital and we have the least. The T.V's I use have built in freeview, Sony and Toshiba, both are lcd, so not cheapies. We pay the same licence fee for a lesser service. Could you please explain why.

Hi Dave,
Sorry for the delay answering, I have customers in both Pandy close & Lakeside gardens who got full Wenvoe service, However there are also reports (thankfully not my customers !) who have reported that trefechan mast has knocked out some of their channels. I cant say for sure but there would appear to be a good chance of reception but it may not be straight forward.
