To: ham-digital@ucsd.edu Greetings! I am a relatively new ham, and would like very much to be able to run the AX.25 protocol directly on my PC, which is running Linux instead of DOS. Are there implementations out there for use on a Unix-like OS? Building an interface card with a different SCC is no problem. 73, Thomas ke6cbr ------------------------------ Date: Sat, 2 Jul 1994 07:33:06 GMT From: ihnp4.ucsd.edu!mvb.saic.com!eskimo!rdonnell@network.ucsd.edu Subject: DR-1200 9600 mod To: ham-digital@ucsd.edu Darren Leno (Darren.Leno@f747.n115.z1.fidonet.org) wrote: : I'm looking for the 9600 mod for the Alinco DR-1200. Also would like to find someone who has done this mod. : Please respond to WD0EWJ@radiohobby.chigate.com : Thanks! I'd suggest the following: 1) get the info from a mods database server in your area, or 2) give Alinco a call. Alinco _used_ to provide this info freely. One of the important changes to the current DR-1200TH2 models is use of a wider (30 kHz?) filter in the receiver IF. One of the weak spots in the modification is that the PLL 'corrects' for the applied FSK modulation very aggresivly, which can cause the receiving modem difficulty when receiving a transmission from the Alinco. Note that they are not solely guilty of this, but their's seems worse than some other common radios, such as the IC-28. Also, the keyup time (TXDelay) required with the Alinco is usually pretty high - 400 - 500 mSec. This is longer than a 256-byte packet. Hope this helps a little. 73 Bob, KD7NM -- --------------------------------------------------------------------------- Bob Donnell, kd7nm bob@ethanac.kd7nm.ampr.org rdonnell@eskimo.com --------------------------------------------------------------------------- ------------------------------ Date: 1 Jul 1994 22:40:08 GMT From: ihnp4.ucsd.edu!swrinde!gatech!newsfeed.pitt.edu!ebe@network.ucsd.edu Subject: Help w/ PTT on Baycom-9 To: ham-digital@ucsd.edu I've just received a Baycom BayMod-9, the tiny modem built into a 9 pin connector. I have one question that hopefully someone has already solved: Is there a way to wire the BayMod-9 to a HT without using the PTT line? Usually this is an option and there is a approx. 3K resistor that gets jumpered into the audio out circuit. There were no instructions included on how to do this, nor is it obvious from the schematic. It would seem that use of this tiny modem with a HT would be common. Maybe it works without any special resistor?
