When i did my last scan, there is only 1 channel that is ITC with a regular STB. The preview channel. There are a few audio only channels ITC with a Turbo8psk.Following your lead, today I installed an offset circular LNB on my motorized dish. I have now scanned in 537 TV and 173 radio channels from 31 transponders on 91W Nimiq 6. Likely they are all scrambled but I will go through them now to check. I used 95W to get the dish pointed then used the 4 degree offset to position the circular LNB as you described. Now I will go looking for circular transponders.
