I consider myself extremely lucky that Dish was able to send me a new OTA adapter for my HWS.
When the tribune stations were removed, Dish sent me an amplified indoor antenna. While I was on the phone, I asked if they could send me an OTA adapter for my HWS so that I would be able to record the OTA channels that Tribune had removed. At first, the person on the phone had no idea what I was talking about, but after checking with his supervisor, he said that they would send me the OTA adapter.
A few days later, there was a package from Dish on my front steps. When I opened the package, I found that Dish had sent me an OTA adapter for the VIP 722k receiver. Oh crap, now I have to get on the phone and try to explain all of this to the CSR (I was procrastinating calling Dish). About a week later (without me calling Dish), I received another package from Dish. This time it was the correct OTA adapter for my HWS! I have no idea why I got 2 OTA adapters or why I received one a week later.
Afterwards, I read all the posts about how the OTA adapters are in short supply, and I realized how lucky I was to get one!
