Tuning satellite receivers
Posted: Mon Apr 03, 2017 3:20 pm
I have recently been tuning a number of satellite receivers using a local signal across the bench. I had great difficulty tuning the 437MHz channels, using an upconverter which moved the frequency up 900MHz. Several receivers were seeing a very strong signal but would not decode a picture and store a channel. To cut a long story short, the signal seemed to be too strong and adding some attenuation allowed it to decode the picture and store a channel. It seems that with signal and quality indication over about 85%, some receivers won't add a new channel. I've not come across this before, it has foxed me for a couple of weeks, and I mention it here in case anyone else has this trouble or can explain why?
