Subject: antenna switching time
Been reading how guys are trying the 9600 baud modems at 19,200
baud and now are looking at switching times. About time too. I have a x1j
node that is using a Motorola Railroad Micor radio (we got 100's of these
at $25). It is on 145.070 MHz and is a 1200 baud Tiny-2 tnc. I
experimented with the tx delay and found that this radio takes about 0.4
seconds to go from receive to transmit!
At 1200 baud .4 seconds is not a real problem, but is an
agrivation that makes you want to put in an electronic switch. But not
quite. When you get to 9600 baud you begin to see the problems. I have
just mounted a Comet 145.07 and 445.01 MHz antenna that will have a Tekk
radio with a tx delay of .02 seconds running 9600 baud and it's tnc will
be connected to the older 145.07 1200 baud system. At some later time I
plan to make the the 145.07 system run at 9600 baud.
Now that .4 second looks HUGE! It takes 1 full packet time to
switch that old radio. So something new must be invented, or a new way to
use the radio so it isn't a problem. The only thing that comes to mind is
a duplex radio that has no antenna switch and the transniter is just left
on until packets stop coming.
Do you have any ideas or tried solutions?

Does anyone know an anonymous ftp site where I can obtain a vt100 telnet client for
winsock that is capable of LINE mode transmission ? Thanks in advance. 73 de Bill kd5lu
