Are there any transponder maps for local HD

[ClemTiger]

or maps showing where the spot beams overlap. I'm just wondering as I will be heading from the Greenville-Spartanburg-Asheville DMA to he Atlanta DMA on vacation. Our DMAs touch one another and was wondering would I be able to receive my "local" channels in HD or SD. Will I be able to receive them at all?

I have seen the satellite and transponder list for the national cable channels. But what about locals?
