From what i found out it's not necessary dish size but the receiver that is causing color bars. I aslo found out that entering manually tp's and frequency work better then blind scan. Here is a review on some fta receivers.
The same dish and LNB were used for all 3 receivers. The dish and LNB are painstakingly peaked on 83W / AMC9.
Dish: Winegard DS-2076 76cm offset Ku band dish.
LNB: DMS International Standard Ku JSC321S 0.3 dB rated
Neusat SP-6000 Standard: Will not lock onto the 11735 transponder at all. No amount of blind scanning or manual entry of frequency and symbol rate data would get a lock on 11735. Tried TP freqency of 11740 as suggested by others on this forum, in addition to 11735. It would get the NBC color bars and the LEO1 transponders without issues at 60- 80% Q.
Captiveworks CW-700S: Found the 11735 transponder with blind scan first try. Signal quality varies from 30- 45%. Picture breakup threshold is 25- 28 on this receiver, so signal was lost on cloudy days, and at night. NBC Color bars at 80% Q.
Conaxant Mini: (Recently purchased new in the box for $46 delivered on eBay!) This receiver allows the frequency stepping while blind scanning to be selected at 2, 4 , 6 or 8 MHz. I chose 2 Mhz and scanned AMC9. It found the 11735 transponder and gets 60- 70% indicated signal quality. Clouds do not knock it out, and it continues to get 11735 / RTV even in the middle of the night. No noticeable dropouts of RTV signal in over a weeks use. NBC Color bars at 95% Q.
