My old USS Maspro receiver died several months ago, so I had to come up with something quick as a dish mover/polarity switcher. I had a used Supra, but for the life of me I cannot figure the darn thing out. Trying to adjust the polarity, setting the satellites, it has not worked out well. Can someone suggest something simple to do that task for FTA? I also have old GI I have not tried, but since the old VC2 cage leaked, I have not plugged it in. It may be fine, but it may not be any easier to work with. I even looked on ebay for an old USS Maspro MR2, but no luck. Any suggestions would be appreciated. Thank you.
