If you have a strong enough signal, it should blind scan in.

now it does.

Next sunny warm day, I'll take my Canadian Tire car battery booster, inverter, S9, slingbox, wifi adapter down to the dish, connect directly to the LNB output with a short jumper, then transmit the video back to my house router. I can use my wifi PC to catch the video from my router while standing beside the dish. Or...I could get one of the many free 13" TVs advertised on kijiji and just hook it to my S9 that's connected to the LNB. I have a plan; I need nice weather.

This will settle for zero cost whether reducing cable length will help the received signal strength of LPB.

Wilspin,
You mean how to determine all of the parameters?
By using the PC Based Tuner, Prof 7500, a Windows PC (Laptop), and Crazyscan.
Basically ya wind up with a poor man's spectrum analyser, with Blindscan capability.
The program reports all the parameters from the frontend for you.
You can also send the entire Transport Stream to TSReader for further analysis, and from there stream a particular channel to VLC for Playback.
Very Cool, highly recommended!

cyberham,
the setup I just described above would be very handy in a case like yours,
Because the program actually does an RF sweep of the entire IF spectrum, you'll get a visual indication of the RF Signal strength across the band.
You could compare a sweep as is down the entire length of your feedline,
then sweep again with the tuner closer to the antenna, and compare the overall levels, and ability to lock known transponders.
After a while you get a feel for what it takes, SNR wise to lock different types of feeds.

If you really want to know what it takes, download this spreadsheet which is useful to compare the measured C/N versus the known parameters a certain feed is using, you can then determine exactly how much margin you have in your system for that feed.

Personally I think something was wrong with that transponder the other nite. I'll try and check it out again later tonite, see if it still acts up on me here.
If it does there may not be anything really wrong on ur end.

@MT--> It seems you recommend the Prof7500, where did you get it? I cant find it anywhere, including *bay.

Cheers, K

majortom · 2012-02-17, 11:18 PM

ur right I don't see them at DRsat's site. I wonder if they might sell them but just don't advertise it?

http://proftuners.com/prof7500.html

It's PCI cousin is the 7301.

PS - Just because I have one doesn't mean it's the best card out there. Honestly, I wouldn't really know
because it's the only one I've ever had. But I have been happy with it.

Check *bay listing 320845806837

If I could get at this price, I would grab it. Are we going to bid against each other?

Yagi · 2012-02-18, 02:40 PM

I am able to receive LPB on my Pansat 9200HD (with the S2 extension) and a 1-meter antenna. Thanks for the info.

It sold for US$50. I feel guilty in letting it pass without trying for it, but the guy wouldn't confirm he would ship to Canada.

wilspin · 2012-02-20, 10:01 AM

This TP is weak. How can i improve it?

cyberham · 2012-02-20, 10:40 AM

1. Reduce losses in system: shorten dish-to-receiver cable length; change cable to lower loss type, eliminate any diseqc switches between LNB and receiver, confirm cable connectors are good quality and installed well.

2. Increase received signal level: orient dish precisely both azimuth and elevation; change LNB for a model with lower noise figure, higher gain; increase dish size.

3. Give up and try for 125W Ku PBS where there is a good assortment of PBS stations also.

wilspin · 2012-02-20, 11:21 AM

Tried 1, 2 to no avail. 3 is not an option as 119 and up are too low on the horizon here.

cyberham · 2012-02-20, 11:40 AM

PBS North Carolina is currently ITC and available from 61.5W Ku. That local could disappear any time, but it's easy to get and strong right now with a circular LNB. Any chance to get OTA PBS from Rochester or Buffalo? You've got a nice tall tower for a high gain TV antenna. Ever thought of going to C-band? I'll bet drsat could fix you up with necessary hardware. I presume PBS is available on C-band.

wilspin · 2012-02-20, 03:34 PM

U got some details on PBS @61.5? Rochester PBS is not reliable this time of year, Buffalo is rock solid always. I just like multiple choices. Spoke with DR Sat last week about large dish. we will see.
