I thought that earlier in this thread you said it depends on what the local supply chain has, not what DIRECTV says you'll get.
It does depend on local supply. But some boxes they have retired, as Directv does not want them around like the HR20/21 mainly due to smaller hds and the ota port on the hr20 confusing people.
Some parts get kept as erp ( replacments) like hr20 we still have but they are esentationally just for people who have them already and and will get a replacment hr20 usually. Because it has built in ota
R15 still very active but start to show up less in new installs and upgrades moving to the r16 which is SWM compatible.
Swm vs No SWM and specific models of recivers we cant specify. like i cant say owhe elite going to get a hr23 I can say that we been not assigning HR20/21 for installs/upgrades as a general rule and mainly issuing hr22/23 as they are the only current hddvr . Just like i cant specify swm vs non swm lnb.
