Hello there surveyors of the world!
I am Dimitris and posting my problem - question fron Greece.
The last 7 years i am a very happy owner of a pair ProMark 500 L1/L2 RTK (base - rover).
The last month i saw some communication problems between base and rover.
The age (sec) on my rover was going up and up reaching 30sec and the back to 1 sec, up to 60 sec and then to 3 sec, sometimes reaching 300sec and DGPS without connection.
The distance between base - rover was 50 meters with view one eachother!!!
I asked a friend to give me his pacific crest modem for my rover and the problem disappeared.
So i need your help here.
Is there any possibility to solve the problem with a new frequency setting of my modem?
Is there any possibility to find a new or used radio receiver kit (pacific crest 80206830 430 - 450 Mhz, 12.5 khz) like mine because the dealer here says that the company doesnt support so old GPS and i will have to buy the whole communication stuff from the begining!!!
Thanks for reading my problem an i look forward to hear some good news from anybody!
