Hey guys any way to find out if the satellite on 127 would cover the carribean better? i tried getting signal from 122 but got nothing using a 1.8 meter.

Anyone other than me have a frequency change last night? ... Rx Freq remained the same (1340.72), Tx Freq changed to 1342.17 (from 1339.25). ... First noticed this about 6AM Eastern. Rx light on, Tx light off, NET light flashing...and SNR of 4. ... As I type this, SNR is in the 7's. ... Speeds are still slow at under 200 down, around 40-60 up. Speeds will improve on the download side around 8 Eastern, with down reaching maybe 600-700, but uploads still below 100. ... Don, I noticed that you and I were on the same frequencies. Did your transmit side change?

Okay, Don. I will check back at a later time to see if your transmit side changed. ... My main concern now is the low SNR. It's now dropped back down to being between 6-7. ... Rained hard yesterday, no sign of moisture in feedhorn, but this feedhorn is "sealed", at lens and at the neck, so could be moisture buildup inside the waveguide. ... Replaced feedhorn with new one because could see lots of moisture inside the lens. Replaced waveguide too. So, if this is condensation within the assembly, I've no idea where it's coming from. All seals appear to be good. ... Dish is a 1.2 Mtr 'Patriot', so could be faulty design.
John, if you read this, I'm located in the mountains at 7300 feet. Daytime temps this time of year can reach 90's, but drop down into the 40's at night. Condensation could indeed be the problem...the main question, how to deal with it? ... The HughesNet dish (.98) has no problems and I've had that feed assembly apart many times. ... On this 'Patriot' dish, the feedhorn, waveguide, and transmitter have been replaced (not the LNB as of yet). The transmitter replaced due to accidental install of a 2 watt. ... In light of all this, it might be that this dish/feed assembly might not be suited for this location due to the harsh weather. ... At this point, I am at a loss.
It's monsoon season this time of the year. When winter arrives, it's time to prepare for upwards of over 100 inches of snow.

Dana, I am far from an expert on removing condensation. I have had condensation in an F1 tria and taken it apart and thoroughly cleaned it and dried it out by leaving it in the sun on the picnic table all afternoon and opening up the feed horn and cleaning it out with cotton balls. I reassembled it, and the next morning there were droplets all over the inside of the cover. Great disappointment. I am convinced that moisture builds up and collects in the LNB and BUC boxes.
I'm thinking that a better solution might be a cylinder of dry nitrogen regulated down to 2 or 3 PSI and connected to the 2 F connectors. I don't think they are airtight. Then loosen up the flange on the waveguide to the feed horn to allow the dry gas to be expelled. After a couple of days, I would think the moisture would be expelled. This is similar to what the phone companies used to do with old lead cables that had holes in them.
This is obviously not a solution for the recreational user, but might be something that MotoSat could try. I will make that suggestion to the engineering manager, and depending how much of a problem moisture has been, see if it gets any traction.
Has anyone else come up with a solution that was successful in the long-term?
Did everything suggested. There was also moisture buildup from within the LNB...that amber colored piece of plastic covering the entrance to LNB is still in place. The condensation was on that piece of plastic. ... At room temp, it disappeared after about three hours. No way that I could get at it with the hair dryer, it just went away on its own.
There is no plastic covering the entry from wavguide into the BUC. I didn't note any condensation, but there were some spots at the entry to BUC which may have been caused by water, but can't be certain. ... I cleaned everything with alcohol and applied dielectric grease to all 'O' seals (thin coating) and more liberally toward the outer flanges of attachment points for feedhorn, LNB and BUC. ... Also applied silicone tape to the waveguide...all of the screws are covered. Some were staggered in formation, which made applying the tape a little difficult, but it's done.
So, will wait and see what happens. A little confused why the LNB would have that plastic at the entry point and BUC doesn't. ... Oh, I left the small plastic cover in place as well at the neck of the feedhorn. ... This is sort of a 'stop gap' solution I think, and would really like to get this solved permanently. ... I marked TRIA before removing, so isolation should be close, but I've read posts where you say that as little as 0.2 degrees can make a lot of difference in failed transmissions. So, might want to check my isolation.
I've seen the SNR higher, at 12-13. At this time, here are the stats, clear skies:
SNR: 11.0 - 11.5 (as I type this, I note it going down into the 10's now. Warming up maybe.) Tx Pwr: -26.5 Rx Pwr: -29.5 to -29.7
Didn't know hair dryers could get so hot. Melted the top of my toolbox that I was using as a support.

Hughes ships the tria as three parts, assembled by dealers or in this case, Motosat. The transmitter is separate, then the waveguide/LNB combo, and finally the feedhorn. As shipped, all openings have stickers over them.
Obviously if they were assembled in high humidity that would be a problem, but most often it is intrusion at one of the joints that is the culprit.

I had moisture in my Weldex backup camera, I sent Weldex support an email and the suggested putting a moisture packet in there, the ones that look like a sugar packet, i put one in there, it seemed to work for a year or so but became so saturated with moisture it actually IMHO ruined the camera. I'm not sure the camera was really sealed good so rain or washing the coach probably got in there. I would hope a Motosat feed horn assembly would be better sealed. Not sure if anyone has tried a moisture packed or if would even fit but thought I'd pass the idea along.

Good morning from Chesapeake VA. I just wanted to drop a quick note, we will be performing a major iDirect code upgrade on 8/17/11 this will affect all users on Mobil Satellite's iDirect service. A notice was sent out last night if you did not get it contact my support team to make sure we have your contact right. All systems will need to up and online from 10AM EST until 4PM. This code upgrade is in preparation of turning up another transponder on G25, this of course will further improve our service and prepare us for additional growth. We thank you all for your continued support.

Finally in a location without trees to block me. Yes, my transmit changed as yours did.
My Rx SNR is 14 here in Peach Beach on the Columbia river. Where are you located? I almost always manually peak mine up when it is low - sometimes it starts as low as you are seeing, but gets above 12 with a few one-count changes (mostly azimuth).

Hi Don, been busy here, so delay in reply. My location is Vanderwagen, NM. I think that the moisture intrusion problem is solved. SNR typically during day of 12-13, dropping to around 11-12 at night. Dish (fixed) may need a little bit of peaking. ... Speeds are still slow during the day, with under 200 down and 40-60 up during day. Evenings might see 750 down, but up is still below 100.
Very quiet on this thread of late. I'm wondering if anybody knows of anyone who has been moved to 123W, and what the performance might be over there. Was informed some are being moved, but no reports from anyone thus far. Dana
