HDR 2000T Poor Signal Strength

Been using HDR-2000T for a few days

Really want it to work, but unfortunately the signs are not great.

My latest problem is signal strength.

I have an older 9200T and compared its signal strength with that of the HDR-2000T

My transmitter is Winter Hill.

The 9200T reported signal strength of 60% and Quality of 100% for all channels

However the HDR-2000T reported quality 100% signal strengths of :
1BBC1 28%
2BBC2 28%
3IVT1 28%
5C5 28%
11ITV3 36%
25Dave Ja Vu 30%
101 BBC1 HD 38%
(other channels signal strength ranged 20% to 30%)

I used the same aerial cable for both tests. I have a pretty good aerial, and have not had signal problems for many years.

Why is the signal strength much poorer with the new HDR-2000T ??

I did noticed that some of my scheduled HD recording failed last night (recording failed : lack of signal). None of my SD recordings failed.

If this box can't record HD channels, then this is a serious problem.

Have just spoken to Humax Technical support.

The technical support chap said my signal strength problems were to do with my aerial ... they said there are no problems with the HDR-2000T, goodbye.

Compared 2000T figures with a 9300 and 9150 on same aerial and they are very similar.

When comparing did you note the mux frequency?

I would re check the tuning of the HDR 2000T.

Check for channels at 800 and up, the OP may be looking at the wrong transmitter. Ironically picked up during a autotune because the new box has more sensitive tuners.

I have checked the mux frequencies. Both PVR9200T and HDR-2000T are tuned to identical muxes 49 50 58 59 (HDR mux 54) ... Winter Hill

comparison of signal strengths (same aerial cable)

mux PVR9200T signal HDR-2000T signal
49 60% 37%
50 60% 30%
58 60% 36%
59 60% 29%

54 n/a 38%

The only difference between the tests is the humax box its self

Is the aerial plugged straight into the 2000T or looped thru' something else?

What if anything do you get on 55 and 31(COM 7 - T2). Is the OP testing one box after the other, or are the results for the older box historic numbers ? What happens if you connect the two boxes in series 9200 first with loop out to 2000T and vice versa.

Are there any amplifiers in the aerial circuitry ?

If a passive splitter is available try fitting that before the HDR2000T (That will reduce the signal level by around 3.5dB and eliminate the signal being too strong).

My aerial firstly goes in to a 4-outlet 'amplifier'. (it also feeds a TV in the back room)

Not had any signal strength issues for many many years.
The co-ax cable from the aerial might is 15 years old and might not be the best but have never had any signal problems with x2 PVR-9200Ts (they indicate strong signal).
Both TVs Sharp Aquos and Sony Bravia are both connected to same aerial ... both have strong signals.

Only the HDR-2000T is showing low(ish) signal strength. It would not matter if it records channels, but it failed on 2 HD scheduled recording early hours of this morning (recording failed : lack of signal).

By the way ... the pictures are watchable on all channels ... again its only failed HD recordings that concern me.

Bypass the amplifier, now check the HDR2000T. The more sensitive the tuner the easier it is to overload the front end. This can result in the indicated signal strength being lower than it really is because of the waveform distortion created by clipping the signal. Remember the transmitter power went up by large amount at dso. Out of interest check the COM 7 mux (31) which is transmitted at a lower power.

I have just done factory default and manual rescan

Mux 55 signal strength 30%
Mux 31 no signal detected
My test were conducted today, one box after another.

I have connected the two boxes in series (v.good idea) This results in a slight strength degradation in reported by the hdr-2000T (all channels watchable)

All tests so far go via aerial amplifier
