5Hz Sirf IV from Mo-co-so
MO-CO-SO is selling a 5Hz Sirf IV chipset usb receiver on Ebay. It's the only 5Hz Sirf IV unit I've seen. He doesn't even have it listed on his website.
Is anyone familiar with this unit? I really want a 5Hz receiver to replace my BU-353, but the other options are using inferior chipsets. The one concern I have is the description says the following for update rate: "1Hz default, up to 5Hz". Can anyone decode that for me or clarify how you "switch" off the 1Hz rate to 5Hz? I tried contacting him, but didn't receive a response.
