Amateur Radio Packet Over 802.11 Cards

Skuld-Chan writes: "I stumbled across this the other day -- basically discusses modifying common 802.11 boards for amateur radio bands (or Part 97 rules). Under Part 97 there is a 100 watt limit and no gain limit (unlike the 6 db gain limit on Part 15). I thought it was interesting :)." Consult your friendly branch of the FCC :) Note that this is just one of several interesting projects from this site.

Hey Gary. How are things in Conroe Texas these days?

Got an 8 bit computer in the back of the closet with two serial ports? The modem part is 4 dirt-cheap chips: XR2211, 567, and 2 RS232 chips. The software is dead easy assembler code.

Back in the old days (1980) the 8 bit machine was the computer. SWTPc 6809 Flex boxes were the favorite, but just about anything was used, including TRS-80s.

Simple!
Just buy an IFR, copy ALL of the LCRs around the areas you drive and set the service monitor to GENERATE, and crank the dial all the way up on the LCR/s frequency of course!
Use and outside antenna to get max range, better still, get the 30dB generate amplifier option IFR sells, that way you can get a much denser signal.

OR:

Buy an old Motorola 250 series bag phone, short pins 20 and 21 together, hit 55# to get (US) displayed, then enter your channel number by keying: 11XXX where XXX is the FCC channel designator, then key in "#" to set that channel.

There are many more "tricks" to add to this, but you get the idea.
To reset the phone, key 01# and you will reset, and then you will see streaming data referencing the active control channel, RSSI and more.

Brute force intermod via 800 Mhz. Type I, II, IIi and LTR radios "may" get you some disconnects, but highly unlikely(806-866), Cell: 824-849/866-894+, A/B bands. Wide filters may get some IMD products through, but commercial radios seldom employ wideband filtering in the TX/RX sections, but hey, try those high powered mobiles on the harmonic relationship(406-470 Mhz. Those old Maratracs are easily "unfiltered".....Micors also.
