Subject: 56Kb Packet Radio Modem
Take a look at:
Section (a)(3)(i) and (a)(3)(iii)
6 dBi for an Omni antenna, with 30 dBm maximum into it.
6 dBi for a beam, with 1 dB power reduction from 30 dBm for every 3 dB of
gain.
Seems at odds with 15.203. But that statute states:
"...Further, this requirement [integral antenna] does not apply to
intentional radiators that must be professionally installed"
It doesn't define "Professionally Installed" but we can assume that they
mean an installation that meets the power constraints, and out of band
harmonic limits.
I seem to recall the old Bonneville Dam microwave towers were set 40 miles
apart
and ran 1 Watt Klystrons into microwave dishes of considerable gain.
31 miles might be a bit much to expect.

Laura:
There are parts of your education that have been missed.
Remember the crystal set?
No power required, all of the components readily available from a common
garden variety hardware store.
No silicon required, no transistors required, no software required...
Have a look at the Crystal Set Society www site.

Hi, name here is Les.
I have a PCB-88 Packet board, cables, power supply, manuel and programs [3 1/2
and 5 1/4 floppys]. This will work both VHF/UHF and HF Packet.
Works with any IBM or compatible computer with an open slot.
Works even better with XPWin etc.
Asking $100 + shipping.
Reply via E-Mail only to kbtgw@spec.net only.

Subject: NEW PSK31 PROGRAM
I tried it. I like the two received signals feature, but I wish you would
have retained some of the user friendly features of WinPSK. Those features
make it easier to use. I hope you will consider adding them in future
updates. I would also like to see an English help file and some user
documentation. All in all, a good start.
