Help on using a Topfield receiver. - Free to Air Satellite Forums (Asia Pacific) - Sponsored by aDigitaLife.com Audio Visual Suppliers

Hi all,
I recently bought myself the Topfield TF3200IR, and I had a few questions with using it. Being a bit of a newbie, it took a while to decipher the manual and actually get it to receive a signal, but it seems to be going well now.

Q1. When using the search feature, it comes up with a long list of channels, which are listed simply as ".", with no program content.

Anyone know what these could be?

Q2. I've seen services listed here in the forums as being on 12525 as well as 12535 (Optus B3), and the Topfield also comes up with both frequencies with the same content on them. I'm guessing that this is the same transponder, and that you can be tuned anywhere in that range to receive a signal (but with less strength) eg you could also get it on 12510 as well.

Would this be right?

Q3. Having a new toy to play with, I was curious to see what else was around on Optus B3, so I roughly estimated the transponder frequencies +/- 62 MHz up and down the band, and came up with 12345 and 12595 (which I didn't have listed anywhere). Keying in these frequencies, with S/R of 30000, came up with a healthy signal on the quality meter, but a search produced nothing.

Would the signal meter just indicate that the transponder is alive and putting out a beacon signal of some sorts, but nothing is being carried on it? Or would there be something else hidden on there somewhere that it can't locate?

Thanks for any help here !

Q1 - Don't know.

Q2 - Probably to do with the selectivity of the receiver. Some are more fussy than others.

Q3 - Apparently they are data channels. The powtek "sees" them but won't lock anything. Lyngsat won't list them for some reason.

Q1
These .(dots) are on the Aurora line up (C1 and B3), I get them with the Powtek and the uec 910 but the Xtreme does not get them.
I assumed they are some sort of placeholders as with the UEC I get an EPG on a few saying service discontinued.
Someone probably has a better explanation

Q2
As VK4BKP mentioned

Q3
I read in a post on Austech that 12345 and 12595 on B3 are both data for an Internet company,
