Elegant exterior, light weight and small size. Some users have experienced a very strong signal which overloads their receiver. This has been reported following a transmitter change which boosted the power, and in another following a software upgrade which improved reception with improved drivers. The solution in both cases was to fit an attenuator or simply a splitter.

This can occur due to deterioration of the installation eg storm damage or water ingress or to an inadequate installation in the first place. Signal quality signal to noise ratio is more significant than signal strength. Solutions may include a better installation, or inclusion of amplifiers close to the aerial.

Some tuner cards have a low noise amplifier LNA which can be switched on by a software change, but some of these eg Hauppauge T require the system to be cold booted ie power down, switch off at power socket for about 20 seconds, then reboot for the change to be adopted.

There are many potential sources of interference such as HAM radio, taxi services and transmitting devices in the house such as moble phones, all of which are likely to start and stop. Interference from other TV transmitters, Tetra, existing phone services and the forthcoming G4 services are more likely to be continuous. Note that in the UK the lowest TV channel is 21 at MHz and superheterodyne receivers are sensitive to interference 72MHz away so filtering may be needed. The regulator in the UK Ofcom has indicated that with the roll-out of G4 mobile phone services in the MHz region a million viewers in the UK may need aerial filters and that 10, will need alternatives such as satellite or cable.

Channels 52 to 60 are most likely to be affected. In a number of transmitters will have multiplex frequencies changed to make space for G4 and will require retuning of receivers. Careful selection and placement of receiving aerials and possible use of filters may resolve the problems.

If you live in a location where your antenna can receive distant transmitters in addition to your local preferred one, you may have the situation where a particular program may be received by one of two different multiplexes transports , and you may well not be aware of these potential conflicts as initial tuned signal quality will be good,.. The distant one cannot be easily filtered out by aerial placement or filters.

Mythtv will find both on a scan and may choose either set at random when subsequently making recordings. To check out the new mux go to the tuning menu bottom left of channel editor screen and scan just that mux,… there is an option to scan a selected mux,.. Also note, not every mux will be available, signal strength transmitter power all play a part. You should then get a full set of good local channels with no duplicates.

One thing to note is that there appears to be an issue with bug scanning linked Mux's,.. This bug has been logged against new Bug Report - General on the 3rd Aug To work around this problem do a scan all,..

The backend log may provide a clue to a problem and will be one of the first pieces of information requested in a forum posting. Messages logged at the start of a recording, the time of failure or the scheduled end time may be relevant and yield clues via a search engine. Some subscribers say that turning on quick tuning has improved Mythtv ability to receive signals. Some have experienced the total loss of a whole multiplex following a change of transmitter line-up during channel re-allocation.

Link to comment. Posted April 22, Gioxy Posted April 22, This behaviuor is related to the nature of digital transmissions Posted April 23, Griga Posted April 23, Derrick Posted April 23, I guess it's obvious that your reception is poor.
