I've always wondered how that LNBF got circular and linear through the same feedhorn. The method that they use seems to work well, but the linear side of the Invacom does seem to be more sensitive to circular signals than other linear LNBFs...
Uh-oh... didn't know that. I will have paid quite a bit for that piece of plastic.
I think I'll go out back today and pull the cover and look, see what is in there.
Keith,
I went out to the dish today, had planned on re-mounting the lnb a little better. While I had it off I pulled the cover and looked inside. It is indeed a circular lnb from the ground up, not a linear with a hunk of plastic the dealer shoved in there. It has a square wave guide with a ribbed metal divider that starts low then gradually steps up to full width. There are two probes at the back, one on each side of the divider, they both point straight up in the same direction. This construction is similar to what I have seen inside other Dish Network lnbs. Made of heavy cast, I'd say this is a well built $28 lnb.

Then you have one of the better built ones (which is good, considering the price!). The circular LNBs (normal circular frequencies) (made by Digiwave) that I have, have the piece of plastic as the dielectric plate in them (at least the one I took apart did). They are no different, as far as the positions of the probes go, as you would find in any linear LNB with the plastic dividing it into two separate zones. Therefore, positioning the plastic in the same manner, it was very easy to convert a linear I had into a circular.
Here is a thread I remembered (going from circular to linear!) which also references Iceberg's experience with a 118 circular!

I was using 2 different editors,one was from the firmware source (stbhdeditor) and another one that was supposed to be good.
Once I switched to the pvr800 editor and tweaked I was able to get the audio.
1meter fixed dish with universal lnb-65% quality on the s10 and it is raining out.
I will stick plastic in the lnb throat tomorrow.
I save the userdb.udf with the rs232 loader and edit that.Once edited,I load to the receiver with the editor.
Saves wear and tear on the usb connector.
They neglected to mention you also have to set the pcr pid.
The editor won't let you leave it at zero,it gives you 2 choices; 32 or 8191
Both give lip sync problems.
They were actually trying to say the pcr RANGE is 32 to 8191; once I set the pcr pid to the vpid,lipsysnc problem went away.
I am trying to get these 3? new channels on my 12 footer Mesh Dish with possibly my C Band or Ku Band Norsat LNB's. But I also have an old Circular LNB. I also now have Sat 118.8W receiving the free C Band Channels ie Tuff TV a while back. Can someone please tell me what or how to use the R & L Polarities are on an AzBox Premium Plus, and how to scan in these new Channels? I'm only familiar with V & H Polarities. Is all the Channel info for these 3 new channels on Lungsat or Sathint? Any replies would be much appreciated.
I receive all 3 almost nightly on my S9 using a linear LNB set for horizontal with 1-metre motorized dish. Receive quality is strong enough for a perfectly clear high quality picture except in the worst weather. All info is on sathint for Anik F3. I had to scan the tp, edit PIDs of the $998 scanned result, then scan / edit again 2 more times to get all 3. Don't forget to edit SID or else a new scan won't get a new $998 result. You must also edit video from Mpeg2 to H264. It's all worth it. These are the best source of those networks on Ku. No special skewing of LNB necessary as for AMC 1 at 103W.

I can receive all three channels as well, but the past couple days it has been difficult due to rain fade. The signal is already weak for me, around 50-60%. But I'm lucky to even be receiving these with my linear LNB.
I find tuning DVB-S2 is tricky since several positions of my dish, only a bump or two either way, may deliver what appears to be a peak quality reading. But usually one of those positions will actually deliver more reliable reception without picture breakup than the others. I think we need a better way to aim the dish for DVB-S2 than merely looking at our typical receiver quality reading. I wonder if there is better technology for that.
chop up some plastic and stick it in the linear lnb throat at the 1 o'clock position.
I used an old credit card.Any non-microwave safe plastic will do-the kind that melts in a microwave oven.
channels will scan in twice and it effects signal quality on those.
If the dish is big enough,no big deal.
I use a fixed dish for 118w and pop the plastic out if I aim for something else.
I does not seem to bother the linear reception at all. I have made that modification about three years ago with a Directv LNB and it worked on 118.7W fine.
Clock the plastic piece at an angle between 1 and 2 O'clock at the top, and the bottom will fall between 7 and 8 O'clock. I works.
Thanks Cyberham, got the PIDS info off of Sathint, but what is this $998 scanned result you noted? Is that what these channels scan in as?
Correct. Isn't this so for you? Immediately after scanning, you will have a channel named $998 along with many others. $998 is the one to edit.

for the s10 I just add on to that channel,I leave it in the list.
Pvr800 editor with the h264 and ac3 options are a must.
Sid can be left at 0

Guys on the AzBox Premium Plus when I try to enter a Channel into the EDIT PID, It asks for:
Channel Name: KNVX
PMT PID: 0
SID: 0
PCR: 4130
Video PID: 0
Video Type: H.264 HD
Audio PID: 0
Audio Type AC3
I entered the above and it won't let me save? It keeps asking: ERROR Please check the PID Values?? Can anyone please tell me what I'm doing wrong, or what PID Values are needed for these 3 Channels??
It says on SATHINT that SID is 0 for KNVX, & SID = 96 for KPNX, & SID = 89 for KSAZ, I have the PCR Values, but what PID values need to be entered for these 3 Channels to correct the Error Message? Any replies would be much appreciated.
