Hailing frequencies open captain!
Kidding, good talk. Skip a few minutes in to avoid an intro. I was skeptical of the UDR56k when it was first announced. When you can get converted wifi modules that can do several megabits in Ham Radio bands, 56K seemed a little slow, and pricy. I guess compared to the common 1200 baud equipment, it's super-fast though. $400 has always seemed a bit much for me.
It's probably a good price though. I'm not sure what it costs to produce but it's probably what the market can bear and there are a fair number of Hams out there with big enough toy budgets to afford to buy these. At least they're not $1000 COUGHICOMCOUGH
eBay has a number of listings for wireless modules for Arduinos listed. There are NRF24 (2.4ghz) modules, and 2.4ghz bluetooth modules and modules based on the TI C1100 and similar chips that can do 440 or 900mhz bands for very inexpensive. Obviously it's a completely different purpose than something like the UDR56K. But could be interesting for some short range modes. I wouldn't be surprised to see an APRS mode one day.
This is a little old at this point but first I've heard of it.
Using RFID tags to beacon on APRS when participating hams are in areas with the proper equipment.
It could be handy to use to keep track of people inside of a large building, or see when people are in
the club radio station. Tags are really cheap and readers can be very cheap too. (At least, assuming
the readers I have seen for $10 are compatible with the tags you buy into)
I'll try to post other talks I find interesting. I seem to be getting hit with a deluge of them lately.
