- You will need a 9600 baud modem that works with the TNC in question. I
- am using an MFJ 1270B + 9600, I have friends who are using the MFJ 1278+9600,
- and the Kantronics DataEngine+appropriate K modem. There are others on
- the market also.
-
- Most radios will work. The controlling factor is that the radio must
- use real FM (not phase mod with pre-emphasis). You will have to modify
- the radio to introduce the modulation right onto the modulator (usually
- a varactor diode) and pick the received signal directly from the detector
- (bypassing de-emphasis, squelch, audio amps etc.) There are quite a
- few radios that will work. The Icom 290 and 271 are among them.
-
- One detail I have not seen mentioned anywhere is that the radios (tx+rx)
- must be within 500Hz or so or 9600 won't work. Using a multimode radio
- is nice because you can usually tune in 1KHz steps. If you're stuck with
- 5KHz steps and your radio is 1.5KHz (or more) off frequency, it will work
- fine for normal FM/rpt amnd even 1200 baud packet but will bw a dismal
- failure on 9600 - worse, if you don't know it's off freq, you'll wonder
- what's wrong!
-
- 70 miles? Sure - depends more on the antennas in use and the terrain
- than anything else. Note that 9600 is somewhat more susecptable to
- multipath distortion than voice or 1200 baud FM/FSK.

- To: ham-digital@ucsd.edu

- I just read the latest issue of 73 mag. It features WEFAX
- as a fun-to-copy mode. Looks great, but the prices of the
- receiving modems are outrageous ($600!). I flipped on my
- Radio Shack Scanner and at 3:47a.m. it started beeping
- away (XYL not too pleased :-) as one of the "birds" passed
- over Chicago.
-
- It looks like the Soundblaster (or clone of SB) would
- be a NATURAL receiving board for the WEFAX sigs. What do
- you think ? has it been done yet ? John Langner, WB2OSZ,
- author of the Pasokon SSTV board was contemplating WEFAX
- as an add-on, but with the advent of affordable DSP cards
- maybe this the SB is a better idea ?

- quite a setup.
-
- try sending to root@bbs.arasmith.com
