Old Receiver vs. V-box (g box) Positioner

[mbaltazar]

Hi everyone, I got a good used 1.8m mesh dish with LNB, actuator and receiver. The receiver is a Uniden Personal Cable 3000 and has programmed old satellites in it. It has connectors for motor, sensor, etc. for the positioning.

Is it possible to use this receiver with current c-band sats/tp ? or Will I need another receiver and use this only as a positioner? or Should I throw it away an get a new receiver and new positioner?
Any help would be greatly appreciated.

Thanks

If the receiver is an old analog receiver, then it is useless except for moving the dish and controlling the polarity.

You can just slave your Merc II receiver to the dish and use it to view the C and KU band channels.

Use a BUD slave kit as this one: BUD Slave Kit Splitters, Switches, DVB MPEG2 Sidecar 4DTV Receiver ....Great Prices

If the dish feed is old- cband version that uses a servo (blue box on the back with 3 wires) then the best way is to completely replace the feed.

The channels (odd/even) are controlled by that servo, and you will have to change channels manually on the old receiver to get both horiz and vert. transponders.

Which is a hassle.

The bsc621 is well regarded in this forum.

I have recently replaced the positioner system on my BUD with a vbox and I am on the verge of replacing the feed with the BSC621.

Thanks Sadoun,
By looking at the BUD slave kit diagram, the old receiver apparently has two RF inputs one for each band (freq. splitter).

My old receiver has only one RF input for C or Ku and the manual says that this input accepts the 950-1450 MHz input from the LBN (c or Ku). would I need another splitter to connect the two signals (c and Ku) to this old receiver?

Thanks Larry,
I don't know if mine has a servo. It had a Ribbon cable (with three leads) going through the feed, however only one lead was connected. I will double check it to see if the other two cables were missing connections.

In the case that just one cable is needed, then I would not worry about the polarity, isn't right?

Polarity matters if you want all the transponders...

You either have a single polarity (one LNB with NO servo) or you have a servo feed. Possible you have an orthomode feed (2 lnbs) but unlikely.

If the feedhorn has a blue or gray plastic box on the back, it's a servo.
The wires coming out of that servo are red, black, white.

The problem with the servo to set polarity is that almost all the FTA receivers now use voltage control to choose h or v. Only some Pansats have the servo outputs.

I already checked and it is a dual polarity LNBF (Voltage controlled H/V switching, 3.2-4.2 GHz), so this one has only one RF output.

I am assuming then that the receiver can send two different >voltages to the feed depending on the polarity. Am I right? But... How could I know if the receiver is analog or digital?

[Larry Acklin]

If the DVB logo is on the front, it's digital. or if it says MPEG2...

Google the model number and I bet you find the manual on line...
