I don't know the in-depth details of the PSDR, but if you're looking at changing that 900Mhz, you may want to look at old (4mbit, 8Mhz channel) Motorola Canopy 900Mhz FSK/PMP100 gear off eBay, as it has a well-designed TDMA protocol and doesn't have the frequency-conversion problems (incl out-of-band interference) sometimes seen with wifi-chipset based Ubnt/MT gear. The Canopy system doesn't use SSID and therefore doesn't broadcast site name, not fully compatible with ham requirements so you could consider it as being run in ISM category. In the Canopy system, the AP and CPE (SM) are different models and only connect to the opposite type. If anyone is interested I can answer questions on network design.

It's been a couple years since I asked about 900 MHz. Has there been any change in the status at Gold Mtn?
It's only deployed @ Gold Mtn. It doesn't work very far, due to the low gain nature of 900MHz antennas and only using 1/2 W transmitter. Feel free to link to it @ 915MHz with 5MHz channel-width. You'll need the Mikrotik 9HPn modem and a vpol antenna of some kind. More gain the better.
Thanks, Bill

Gold's 900 is up and running - in fact we were just debating it a bit on the list a week or so ago, discussing whether anyone was actively using it and/or interested in experimenting with it, or whether to scrap it and take it offline. Mikrotik no longer makes a radio to use 900, so if we want to work with it we'll have to look at alternatives. There's a MT baseboard with a ubiquity daughterboard that Spokane folks are using we can look at.
What is your interest in 900 and where would you like to see it go? I think the project has some value for some of the non-LOS sites at a lower data rate, but do we have enough people interested to make it worth the effort is the question?
Cheers, Rob

If I can get equipment I'd love to try to shoot it from Tulalip Bay. -Joe -- Joe Hamelin, W7COM, Tulalip, WA, +1 (360) 474-7474
