I've been running one HR21 with an SWM (coming from a new Slimline dish on a non-penetrating mount) since March. A couple months back, I started getting a "Searching for Signal" error on ESPN (206). Since I was able to receive ESPN on another channel, it wasn't a big enough deal to call DTV. This morning, however, I got the same error on the new Fox News HD feed. Checking around, it has spread to a few other channels (HDNet, ABC Family, to name two). DTV can't get here until Monday, so I thought I'd ask here.... Is this more likely a dish alignment issue (due to the mount) or an SWM issue?
