DirecTV receiver with Dish Network dish

[qw3rty]

I tried hooking a DirecTV receiver up to a Dish Network dish. The receiver got a 90% signal on the odd transponders but 0% on all of the even.

I tried skipping the multiswitch and just plugging the receiver into one of the two LNBs, it still gets just the odd transponders.

Is the problem that I'm using a Dish LNB with DirecTV, or is it something else?

As I've been told, the switching signal is not the same between the two.

Sounds like a Dish Pro stacked LNB rather than a voltage switched Directv LNB.

If it is an old enough dish lnb it should work for SD from 101 but as Boba said it sounds like it is a DishPro LNB that sends the Odd and even tps at the same time by stacking the evens at a higher frequency. I think there is a way to make a DishPro LNB work with the older method but that might only work for dish receivers.

I think it's actually the DishPro Plus (DPP) LNB that also works with the older legacy dish receivers and therefore may work for the voltage/22 KHz tone switched DirecTV receivers as well.

But it only comes in the two LNB twin version for 110/119 I think, though it should work if pointed at 101. Then again I'm not totally familiar with dish equipment.

The only Dish equipment that will work with DirecTV receivers is "legacy" (i.e., non-DishPro or DishProPlus) LNBs. No Dish Network switch, including the ones integrated into the multi-LNB packs, will work, nor will any stacked LNBs (DP/DPP).

Just one other question BattleZone, will a DirecTV receiver work with DishPro equipment by means of a DishPro legacy adapter such as here?--

Though hopefully, should it work that is, the OP if he chooses this route can find a better price than this for it. :rolleyes:

That's a good question and one I don't know the answer to, because given the costs involved, and the ready availability of DirecTV basic dishes, there's little reason to try. But maybe I'll give it a shot and see sometime. :)

Directv receivers don't send DISH switch technology so why not just buy a $10 Legacy/Directv LNB if your going to buy something.

Well I don't know if a DirecTV 101 degree LNB will fit into the support arm of a Dish "500?" which I guess is what the OP has. So it may require an entire phase I round dish assembly. But again the oldest Dish legacy equipment used the same 13/18/22 KHz tone, signaling scheme as DirecTV still does, so as BattleZone noted legacy LNBs will work as will the backward compatible DishProPlus LNB. Also the use of DishPro equipment with the legacy adapter should work as well.

But you are correct in that all above this basic standardized voltage/tone signaling method used by both DirecTV and Dish legacy, and into various digital switching code schemes used by the two are definitely incompatible with one another and highly proprietary.

This also sort of bothers a tech guy like me however since I would like to completely understand things like for instance the specific signaling protocols DirecTV receivers use to actuate the B-band converters, or communicate with a SWM module or SWiMLNB over that narrowband 2.3 MHz control channel. Heck, I was never able to really find out exactly how the receivers signal the common 72.5 and 95 degree flexports on a multiswitch.

These proprietary signaling schemes are apparently held very close to the vest by both the DBS service providers.

Oh sure, but as I posted that link from e-bay as an example. If the OP or some other wants to drop about $20-$30.00 on one of those legacy adapters and use a Dish 500 with a DishPro LNB then that is not too impractical.

But for SolidSignal and others retail prices for the adapter, no way, forget it. :nono: Just go out and pick up a Phase I DirecTV dish for 101 degrees.

HoTat2:

"In the beginning" an LNB was an LNB. DirecTV & Dish used the same ones.
As switches were needed, the switching signal used by each was different.
Dish later moved to a stacked transponder system, while DirecTV didn't, and went with more switching.
As for the flex-port dishes, their signal is slightly different [than the 13/18 volt 22 KHz tone/no tone] as these needed something more than the four combination.
SWM uses a 2.3 MHz "comm" signal instead.

[BattleZone]

I have all the parts in my shop; I just meant that it wouldn't be cost-effective for an end-user.

Also, you can use a DirecTV legacy (i.e., basic, 101) LNB in a Dish 500 dish. The plastic adapter won't close completely, but the LNB will fit in there tightly enough to work just fine. But, given that I see free basic dishes for free on Craigslist all the time, it seems like a lot of trouble...

This also sort of bothers a tech guy like me however since I would like to completely understand things like for instance the specific signaling protocols DirecTV receivers use to actuate the B-band converters, or communicate with a SWM module or SWiMLNB over that narrowband 2.4 MHz control channel. Heck, I was never able to really find out exactly how the receivers signal the common 72.5 and 95 degree flexports on a multiswitch.

In the past Tom has said that both the BBCs and the 72.5/95 sats on the flex ports are selected using DiSEqC which is the same thing Dish uses for their DP/DPP switching.

The SWM communication channel is something completely different I believe.

Thanks, corrected my original post. I thought that's what it was but choose otherwise for the SWM control frequency which turned out to be incorrect. :o

Yea, I heard that, but that's pretty much as far as is known. As I've never been able to locate any sort of published material detailing the specific digital switching signal protocols for either DirecTV or Dish equipment beyond just general references to DiSEqC or some other.
