Well, I'm done for the night.
First attempt at a permanent non-ghetto looking solution has failed.
I bought some 1/4 aluminum wire mesh from a hobby store. I also bought a big bag of ferrite chokes.
1. Place EVERY ferrite choke I bought on power cable. Same RFI happens....although now I can only get it to respond on 10m/100w. This new band is the same for every party the test. For some reason 80m isn't bothering it now.
2. Remove chokes and ground chassis to nearby cold water pipe. No luck. Remove new wire.
3. Spray painted on one side of the wire mesh (black). I was very proud of myself as I wrapped the HR24 like a Christmas present. I grounded it to the rear metal chassis. I wrapped the top and sides only, leaving the front panel free. I even took pictures because I was so proud. 10m/100w still causes RFI.
4. I break out the foil again. I wrap it front to back, leaving the sides exposed and torn in front to allow for IR control. Problem solved.....again.
I need to either get some superfine copper/wire mesh, or back some regular aluminum foil on black construction paper. Then proceed to wrap the IRD in black paper, leaving the sides open to vent. Hopefully that will work.
Even though I failed tonight, I still learned what I need to do. I even made up a neat connector for grounding the shield. I took an rg6 connector and made it up without a center pin. On the other end of the three inch cable, I stripped away all but the outer shielding, twisted the braid together. I poked that through the screen mesh and soldered it on. This way, I can just screw the rg6 connector onto my unused coax port on the back to use as a chassis ground point.
On a side note, does anyone wonder why there isn't a three prong cord used on this unit? I guess they get grounding through the coax shield? I double checked, my coax run is grounded at the dish.
The fight shall continue tomorrow.
You have confirmed the difference between an electrostatic shield and a grounded shield. An electrostatic shield is only effective if not connected to the proximate ground system (like power line ground). Once you connect the shield to ground, you get coupling from the existing poor rf ground and lose the "electrostatic isolation".
This is why the aluminum foil works by itself, but the grid of wires connected to a ground don't.
The problem may be two fold:
Direct radiation, which the aluminum foil kills.
Common mode coupling which the grounded shield wired actually make worse, not better.
Stick with the electrostatic shield.
Possible elegant solution:
There a some companies that make a spray on copper ....Form up something that can go around the receiver (maybe card board?), spray it with the copper paint...it should work like the tin foil, but be more aesthetically pleasing.
