[QUOTE="Lazarus, post: 1099171, member: 323322"] DECT (and other potential interference sources) exploit weaknesses in screening. Receivers themselves are generally immune owing to the Faraday Cage effect. But cabling, joints, connections etc. are fair game for exploitation. Because one person's installation is unaffected does not mean that someone else's is and the OP would be advised to spend a few minutes powering down any and all potential interference sources - Cordless Phones, WiFi Routers etc. to see if the missing channels issues resolves. If it does, restore power sequentially until the culprit is identified. If it turns out not to be an interference issue, then little time has been lost eliminating it. Well worth doing before carrying out further dish tweaking. FYI, latest generation DECT work at around 1.9 GHz (earlier generation around 1.8 GHz) which corresponds to downshift frequencies (signals carried from the LNB to the Box) relating to Ku band Transponders close to 9750 + 1900 MHz (= 11650 MHz) and 10600 + 1900 MHz (= 12500 MHz). The Transponder at issue is nominally 11686 MHz, so clearly prone. [/QUOTE]
