Your service provider should provide you with an options file or  they should send the options file direct to your modem over the satellite carrier to your site.

This is an example iDirect options file

In this example a set of transmit configurations is shown.
     tx_freq = 1000000000
     tx_bitrate = 336000
     tx_mode = 0
     tx_modtype = 1
     tx_clksource = 0
     tx_fecrate = 5
     tx_scram = 1
     tx_diff = 0
     tx_specinv = 0
     tx_power_in_dbm = -5.000000
     rx_fsd = 28796
     tx_spreading_factor = 1
     rx_spreading_factor = 1
     tx_spread_enable = 0
     rx_spread_enable = 0
     is_demod2_active = 0
     rx_symrate = 5736164.973838
     tx_symrate = 254485

You need similar (but specific to your site) data for your particular site and satellite network.

Ask your service provider to resend (push) your options file and restart your modem. They should be able to do this remotely if you are tuned to their outlink carrier.  If they change their outlink frequency or outlink parameters all their sites need to be updated. Maybe yours was missed if it has been powered off for long time. 

I don't know the location of the options file in the modem, but I believe that iSite program on your PC is able to inspect the options file and possibly allow you to extract the file and back it up.  Please tell me if this is possible.

Rx lock but issue is modem can't find Tx carrier to tranmsit, in modem logs show no Tx carrier found I think this mean configuration issue not BUC bcz modem still can't find Tx carrier , so which file in modem I can check to see the Tx carrier configuration?

Just a recap on how to get started with link budgets:

First you need to get a good understanding of the G/T, PFD and EIRP data about the satellite transponder.

Get hold of the coverage beam maps.

The uplink coverage map will show uplink G/T contours. Note down the G/T for your uplink location. This is the only reliable figure which does not need adjustment.

The uplink coverage map contours are also needed to find the uplink PFDsat for your site. PFDsat figures are shown against each contour lines. Unfortunately you need to know  what gain step setting of the transponder they refer to. Ask the satellite operator.  They can tell you what is the gain setting of each transponder. Make sure you understand which contour the PFDsat refers to. It might be the beam centre. It might be some beam edge (e.g -4.5 dB down), or other contour.

Also, while you are at it, ask what input and output back off they require for single carrier and multicarrier operation and what carrier/intermod is expected. For single carrier in the transponder 0 dB or 0.5 dB output back off might be applicable, for multicarrier operation maybe -2 to -3 dB. 

The downlink EIRP coverage map will show the EIRP levels on the downlink beam when the transponder is saturated with a single carrier. When the transponder is operated with multiple carriers the transponder operating point needs to be backed off to reduce intermodulation interference to about -21 dB. The output back off might be something like -2 or -3 dB reduction from maximum EIRP, depending on how linear is the satellite downlink high power amplifier.

You will often find that actual operating conditions do not match your calculated link budget. The reason may be that the contours are "the specification" and the actual satellite performance is better, e.g. higher G/T and higher EIRP. Over the satellite life the performance may degrade to "the specification" values. Your own allowances for uplink, intermodulation and downlink interference will not match reality, varying over the years.

Now you can start a link budget calculation.

I hope that helps.

Do a return link link budget with the help of the satellite operator. Details you need are the satellite uplink G/T contour over the site and the uplink power flux density per MHz on that contour normally used by the satellite operator for a transponder with multiple carriers.

I am using 1.8 m Antenna C band for remote &
5 watt BUC.
My customer want to use 4M internet access.
Is it possible..?
if not how much BUC power should to need to gain
internet 2-4M for customer..?
thanks
