In February of this year I replaced my RL80C and L760 with eS127 and eS97 MFDs. At the same time I replaced my radome with E92143 24" HD Dome. My old system had a 1 year old RS130 GPS so I chose to keep and use it.

About 7 weeks ago I started getting GPS Lost Fix errors. I found that switching the eS127 (Data Master) to use its internal GPS is a workaround for the lost fix problem.

The RS130 is located on top of my radar arch and about 8 feet from my two VHF fixed antennas. The RS130 works fine and the barograph shows good signal strength until I key a VHF radio, at which time the RS130 will lose fix. Also when my hand held VHF is keyed, on low power if it is 5 feet or less from the RS130 it also loses fix.

The status LED atop the RS130 will be short flashing green until the VHF is keyed. It will then go to short flashing orange for about 4 to 5 seconds, at the same time the satellite signal will go to near zero. If the VHF key is held longer than 5 seconds the status LED will return to green and the signal strength will return to about 50% of normal. Again the problem goes away when the key is released.

I have checked everything I know to check and suspect the RS130 is to fault.

Do you think the problem is in the RS130?

I purchased the RS130 1/30/17 1 year and 4 months ago. Can it be repaired?

I have attached a drawing of my system just in case you suspect there is something else wrong.

Thanks for your help,
