meter for iDirect on IS904

[freeby78]

Hello-
Thank you all for taking time to answer this one for me.
I support the IT operations of a non-profit org that is setting up a site in Africa. I will be traveling there in May to setup a C-band 1.8M dish for iDirect service on Intelsat 904 at 60 deg East. I have read a great deal and experimented some with satellite equipment, but never commissioned such a system. I am looking for the best/most cost effective meter to align the antenna. I must have something that WILL work since once I board the plane, all alternative options from the civilized world will be left behind.
I have observed that professional technicans installing systems in that area usually carry a spectrum analyzer and am prepared to purchase one if that is what I need. I have also seen several of the advanced digital meters like the Birdog and Sathawk which claim to work for vsat installation, but things looked a little more shaky when I started reading their manuals.
So, there is the first issue of getting the correct transponder ID into the meter, which seems doable even if it takes some work. The catch that I'm unsure about is that the "West Hemi" C-band beam on IS904 that I will be aiming for does not have any TV channels according to lyngsat.com. Will these meters that are designed to work for TV signals work for aiming at that particular beam? The iDirect uses TDMA, so I feel confident that I can't lock on that particular signal, but I have no idea of all the signals in that beam of if there is some standard signal coming from all C-band birds with basic identifying information (Network Information Table aka NIT?) that would allow me to make a positive ID and align properly.
I liked the feature in the digital meters of selecting my satellite and then aiming until I get a beep. Does the Mark III or another low end spectrum analyzer have that sort of capability, or am I to look for blips on a screen as I am scanning the sky?
Thanks for helping out the new guy that has a decent technical background
