Subject: 2Mtr RTTY/PSK31
Hello All:
Looking for PSK31, RTTY or any other digi activity on the two meter
band (not FM packet); particularly in the NE region of the US. Can
anyone point me to the freqs in use and I assume most are horizontally
polarized.
Tks,
de Richard/N2JR

How many analog electronic designers are there? How many were there last
year? Do you think this is a trend?

My parents are going to lose their home if I cannot raise $1,000 by next week!
I would appreciate if everyone could donate money to me by sending a donation
through paypal to shocker1@nurb.com! If you could do this for me I would be so
greatful! If you cant send me some money, atleast join up under
shocker1@nurb.com at www.paypal.com and I'll get $5 for everyone who joins
under me. Please help me save my family. If you do this I'll be eternally
greatful and will return the favor once my family gets in better financial
condition!
P.S. If you send me any money through papyal, email me afterwards and when I
get back on my feet I'll be glad to repay you what you lent me!

Subject: IP Over packet radio : Help
Hi,
I am exploring the application of a point to point radio link between
two host computers for an academic project. Ultimately, I would like
to write a Window NDIS driver to interface to a an RF modem via a
RS-232C connection.
Does anyone have any experience in this area? Any suggestions as to
whether its technically feasbile or not? Ultimately, for this acedemic
project, I would like to take an existing UDP/IP application an run it
over this radio link.
Any advice would be greatly helpful. I have look at a pair of RF
modules by a Abacom and it seems to be feasible.
How about Amateur packet radio? From what I have read, it looks like
with packet radio, you use a TNC to bridge the host computer and the
radio. Is it possible to interface a VHF/UHF transceiver to a standard
modem and write the NDIS driver on top of that? My understanding is
that the standard analog modem would handle the digital RS232 interface
and accompanying digital serial data and modulate it onto a typical
carrier signal for transmission over POTS. Could you take that signal
and route it to a VHF/UHF transceiver for transmission? If that even
possible or is that just plain crazy?
Are there any other valid, feasible solutions? The ultimate goal of the
project is to write the driver and hence the data link layer (handling
all the error detection, flow control, etc) and ultimate provide
solution to run this particular UDP/IP application over top of it.
As for data rates, I have read about numerous RF modems that claim they
can achieve over the data rates of 38.4Kbps (in theory anyway) using
GMSK and DFM. Any recommendations on hardware?
Do I still TNC if I am writing the NDIS driver?
Thanks in advance!!

IP via amateur radio links first occurred during the 1980's.
