Here are step-by-step instructions for the installation of the Phone Jack Jtag in your receiver. It is fairly simple and can be done in about 30-60 minutes depending on your skills. For best results, take the time to read this carefully and follow the instructions in the order in which they are written here without burning any steps.

WE ARE NOT IN ANYWAY RESPONSIBLE OF DAMAGES YOU MAY CAUSE TO YOUR RECEIVER!

You can use the existing Phone Jack from the Receiver to have it changed into Jtag Jack for easy access.

 
Step 1). Open receiver, take the board out and locate the Phone Jack (I used a 3100 for pics, but you can do the same with all):

If yours only has 4, just go and buy a 6 pin Jack and replace it.
 

Step 2). Locate the 6 pins from Phone Jack and cut the 2 traces:

Below is a pick with the 6 pins numbered to coincide with the Phone Jack connector pins:

Step 3). Solder 6 wires long enough to reach the TSOP Pads. You can have them longer as you can shorten them when you get to soldering to TSOP Pads
 

 
Step 4). From pin 6 solder to the IRD case (Ground).

 
Step 5). Solder wires to TSOP Pads and use the table for your Model IRD. Shorten wires as you solder them, do not leave any extra lengths.

Step 6). Now we'll make the actual Jtag:
You need a D25 PC Parallel Port connector, 5 x 100 ohms Resistors, one 6 wire phone male connector, a 6 wire phone connector crimpier, about 10" of 6 wire telephone cord, a case for D25 PC parallel port connector   and a pack of cigarettes.

D25 - solder a straight wire between pin 18 and 25.

I will just let the pics speak for themselves:
