Hello - I recently connected a UHF/VHF antenna to my Directv HR20 receiver. I can get the UHF channels but I can't get the VHF channels (like WJLA channel 7). When I view the signal strength for WJLA, it is a solid 80+% but yet I get no picture. When I feed the OTA signal directly into my TV, I get a picture. Has anyone else experienced a problem receiving VHF using an HR20?
Your post is a little dated, but I thought i would respond that I have two D* HR20. I can get WJLA fine on both. I live in southern PA and have an outdoor VHF/UHF with an amplifier. You will need to set up zip codes for DC and Baltimore and then do a rescan. You cannot move the antenae and update the scan as it will over write your previous scan. The zip code channels will not be lost. You may need to do this several times (when receiption is excellent to get the channels outside of the zip codes into the receiver). I usually do zip codes for DC and Baltimore and scan for the PA channels. You can use different zip codes and get different channels (For example a Bowie, MD zip code may list different channels than a Alexandria, VA zip code - but both are DC).
