I'm at work right now so offhand I'd guess they are 5/8" bolts as they are pretty stout.  You could go over to the Tek2000 website and shoot him a email and he could probably tell you what size bolts they are.  Since the dish is made in China it's a good chance they are metric bolts and not SAE.

I ordered me a new bolt kit and a ASC1 for my setup.. so hopefully I can get it figured out.

I took today off of work due to the severe weather. With a rare day off I want to try to tune this TP. I currently get zero on the signal meter for DW. I have not set up a dish from scratch before so this is a learning experience. The weather is not suitable for checking the f/d and centering of the feedhorn. What else could I try as far as tuning the dish at least to get a signal to register? Currently SES 3 ku is coming in fine on both polarities. Puzzled...

pull down or push up on your dish and monitor the signal to see if it increases at all. It might be a simple adjustment to fix your problem.

I pulled down on the dish while my son was watching the TV screen and the signal jumped from zero to 94 on the DW transponder. I was really happy about that!
But once I let go the signal disappeared again. Any idea what adjustment needs to be made?

Keep in mind that you'll need an antenna with < 2 deg Beamwidth.
The sat next to 103w is rather strong and has some radio muxes within the same spectrum as the DW mux.

103w
4140 V 30000 with a bandwidth of 36 MHz
So on 103 w 4122 thru 4158 MHz is occupied by the DW mux.

Next door at 105 W on the same polarization you have:

4122 V 2400 BW of 3 MHz
4132 V 5000 BW of 6.75 MHz

On smaller CBAND antennas with a BW > 2 degrees, these two signals will present themselves as interference to 4140 V 30000 on 103W.

example, here on the PT 7.5 antenna
105w
4132 V 5000  12 dB BW 6.75 MHz
4122 V 2400  13 dB BW 3 MHz

103w
4140 V 30000 at FEC 5/6 is only 9 dB, which isn't good enough to lock.

edit: I believe DW moved to 4140 V 30000 about 1 1/2 yrs ago, while the radio signals moved
to 105w just a little over a year ago.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
