Don't bother as that dish and receiver will be obsolete when DTV finishes shutting down the MPEG2 channels.

Hi shannon02. Many thanks for this information. Yipes, does that mean my whole system will be obsolete soon? Do you know when this will happen or where I can get the information about this? Not sure if this is a regional thing but I live in the San Francisco area. I've been thinking of replacing the entire system with something new that will also give me wi-fi on the boat. Do you have any recommendations on what to replace it with? Can I at least keep the dome on the boat and fit the new antenna inside?

Unfortunately it will not matter what remote is compatible. DirecTV is currently shutting down their MPEG-2/SD-only feeds. That M10 will soon be a brick, if it isn't already.

Going forward you must have a MPEG-4 setup. DirecTV is doing a complimentary swap of their standard equipment for the residence on the account. However, custom setups like a boat are at your own cost.

Currently the boat MPEG-4 option for DirecTV is the Intellian s6HD.

Sorry it wasn't the answer you were looking for. Just wanted you to know sooner than later when service no longer works at a bad time.

The shut down started in 2019 but COVID-19 and AT&T selling off 30% of DTV has changed things up.

The only HD dish made for boats is the Intellian s6HD that sells for around $9,000 and no it will not fit in your dome.  The KVH TracVision HD 11 website says it works on boats also.  As for internet DTV doesn't provide it.

Tks shannon02 and Juniper for your help and advice. What started as a search for a replacement remote has had an expensive outcome!  I think I need professional advice and I'll start looking for a replacement system and installer. With thanks, Johno_88

Yeah that is a price shock when you were thinking just a remote. Wish we had a better answer. At least you can look into options before the shutdown hits your legacy equipment.

If you've got other boxes, such as the normal ones at home, if you post back the model numbers we can let you know if you are affected there.

You might consider getting Starlink satellite internet and switching to DirecTV Stream or another streaming service. 

As a note DIRECTV started adding HD channels to their 101 location so you may not be completely out of luck (as far as the satellite dish goes). If I recall correctly the M10 powers the dish over the 12V on the coax line, so I’m not even sure how you would power the dish with a traditional HD receiver like an H24 or H25. You’d need a new dish altogether as others have suggested.

AFAIK there are only 4 MPEG4 channels on the 101 and they are all news IIRC. There are rumors DTV may add more.  DTV receivers send 13v for the odd transponders and 18v for the even transponders to the dish before SWM came along. AFAIK there is a separate power supply to do the aiming of the dish

Thanks everyone for your help and suggestions. I'm liking the Starlink satellite internet suggestion which seems a relatively affordable option.  It's probably not appropriate for this forum but has anyone had experience on using Starlink on a boat or rv for internet and tv?  I don't plan to watch tv when cruising offshore -- only when on a berth in a marina (ie stationary).
