#Radio links
2 messages in this thread
I'll keep you posted on my explorations with the JetDirect card. We
still have one program that requires Windows, otherwise, I try to
keep everyone here at the office on WinNT instead. It's so much more
reliable.
As for the radio questions, yes, I've been lusting after these 900
Mhz spread-spectrum radio modems for a fast data link. It would be a
great link between home and office, but because my office and home
are separated by six-eight blocks, it's tough to justify. It's a
three-minute commute if I hit the one stop light in-between. 🙂 But
it could be a video conferencing link, for example. It would also be
a great way to link to an Internet service provider if they were
close enough or the propogation was possible. My current provider is
33 miles away as the crow flies, and the topo maps tell me there's no
more than 100-200 feet elevation difference.
How much was that nifty video transmitter?
Hi John,
The video transmitter board cost US$139, another US$39 for the sound subcarrier
board. These are assembled boards with no cases, connectors, or anything else.
Tuneable receive downconverter was another US$99 and is assembled in a case
with connectors.
This equipment does require a license. It is covered under my Amateur radio
license, and must be used accordingly, i.e. no business use.
Don't know enough about unlicensed S-S RF modems to have any idea of kind of
range they can reliably cover.
How modern is your TelCo provider? Maybe they have ISDN services. This should
give reliable, high speed, and secure connection to your office.
My local TelCo office is all relays – don't even have caller id here. Should be
coming into the 20th century by the end of '96.
The closest internet provider I know of is 6 times as far away as your
provider, thus I am not on there at this time. My CIS node is about 20 times
further than your internet provider – long live AutoPilot!
Hmmm.. six to eight blocks, eh. Do you have direct line of sight? If you do,
get a couple of high power solid state lasers…..
