Under atmospheric high-pressure, distant transmissions (from France or the UK) can break through and interefere with the signal you want - Caradon in this instance. If things are back to normal now we have a low, this would be the most likely explanation. If the problem persisits, you might wish to check whether you can get a signal from Huntshaw Cross on a CD aerial.

Dave Fletcher: Mark's advice is sound. However, you may find that a log-periodic aerial serves you well. I receive Caradon
at 50miles on a log from ATV :-) If Caradon is weak at your location, the group A aerial recommended by Mark would be best, but, being longer, needs a sturdy mount. A log is robust and wideband and normally should give you a good signal at 20miles. It would also allow you to try other transmitters in the Southwest if you were interested in experimenting.

My signal comes from Caradon Hill. I have a one year old TV with integrated Freeview. The aerial is in my attic, not exposed to the elements. I have never had a reception problem. But since the past three days approximately, I have had "no signal" on all the ArqA multiplex channels (aerial group C24). I tried doing a Freeview reset, and that resulted in all the ArqA channels disappearing from the EPG. I do not have a digibox, VCR, PVR or games console or any other analogue video equipment. Also, we do have any new electric equipment that we have plugged in in the past few days. I tried to manually tune in C24, but my TV digital setup showed on C24 signal quality of 0 and signal strength ranging between 0 and 7 out of 100, so the TV could or would not tune in C24. Any ideas?

Paul: At 5 miles away from the transmitter and with only a minor obstruction being seen on the signal path (about 0.25 mls from you) is liable to suggest that some problem "might" exist with your aerial system albeit I do acknowledge the fact of you having said that its located in the loft.

As you haven't actually mentioned what the other channels are indicating, what you should do is go into the tuning menu / manual tune and enter Ch21 (ITV3 etc) but do NOT press search or scan, because on practically all devices with a manual tune facility after you have entered the channel number the level of the signal will be seen, make a note of whatever it is then carry out exactly the same procedure again but this time enter Ch27 (Film 4 etc), once again noting the level, then finally repeat as before but use Ch24 then compare this with the levels that's been seen across the other two commercial mux channels, and which by the way all radiate on 50Kw compared to the PSB's on 100Kw.

Its quite common for levels to change over the year through atmospheric reasons, but not with the magnitude such as you are reporting.

It might transpire that you will require to move your aerial about 12" or so either side of where its presently positioned, this done while leaving your TV on the manual tuning procedure as mentioned as its tuner acts like a signal meter when used that way, but further advice is dependant on the results of your test.

By the way, work was going on at Carradon Hill yesterday connected to DAB radio but not according to info the TV services.

Any idea where I can go for help - mine is a Radio 4 FM problem - all of a sudden, about 3 weeks ago I get huge intereference on Radio 4, on all four radios in my house although Radio 2 is still acceptable. Reception has never been brilliant - I believe we get the signal via a relay station & we've only ever been able to get Radios 2 & 4 but now 4 is unlistenable to!

Hello
I receive my signal from Caradon Hill & am unable to get an HD signal on my HD tv. I have manually tuned to Ch22 & "no signal" is shown. The aerial is in the loft.
I have the ability to receive the Redruth transmitter but get the same result. Can you advise please.

Ron Bouttell: Have you previously had a signal on the HD channels or are you trying to get them for the first time? If the latter, please post your make and model of the TV.

Hi Ron, Michael,
I receive from Caradon Hill and have recently bought a Freeview HD recorder which didn't initially detect the HD channels, but I manually tuned CH22 and it picked them up and I could watch them. A couple of times I've tried watching the HD channels and I've had the 'No signal' error. Manual tuning shows good signal strength (80%) but no signal quality.
Today (Sun 14th) approx 2pm I tried the HD channels and got the blank 'No signal' but approx 5pm I could watch the HD channels and signal quality had returned to 100%!!????
Any ideas??

Hi Brian,
Thanks for the link.
I have just checked my Freeview channels at 11am and I can see a significant drop in signal quality readings across all channels, resulting in no CH22 and some freezing on other channels. But CH22 was fine last night!?
I will look at getting an attenuator, but shouldn't this problem be constant rather than am/pm?
