I noticed a new Starbucks drive-thru in my town was
using headsets to take orders and decided to find out
what frequency the were using.
I tried all the usual low band, hi band, UHF & 900MHz
frequencies with no luck.
Finally I resorted to going inside with my Scout counter
and a PRO-83 set on close-capture. Still nothing!
Finally I asked an employee with a headset on if I could
take a look at it. He was happy to show me how it worked
(all the time still no action out of the Scout or PRO-83).
I noted it was a H.M. Electronics unit with blue buttons
on the beltpack portion. I thanked him and went out wondering
if my gear was not working properly.
At home I looked H.M. Electronics site on "Google" and found
that HME has a new system called "Wireless IQ". Checking out
the PDF for this system I found that it uses 2.4 GHz Digital
frequency hopping & time division duplex. No license required.
So much for listening to people order coffe at this Starbucks.
I guess we will have to wait for Uniden & Radio Shack to
come out with something new or join the NSA.
We can always hope their 2.4 GHz wifi hotspot will be messed up by it and maybe they will go back to analog.
