[amsat-bb] FalconSat-3: UZ7HO's Soundmodem Full Duplex Mode?

Discussion:

All:

Regarding Falconsat-3:

I have two 9600 baud rigs connected to 2 separate sound cards. Each
sound card is connected to a separate instances of UZ7HO's Soundmodem so
each rig has it's own independent modem.

This setup works perfectly in the shack, but I quickly found out that I
can't get each instances of Soundmodem to talk to the terminal program
at the same time.

I tried using one instance of Soundmodem with one sound card on the
output and the other for the input, but the input card mutes when you
transmit on the output so it doesn't appear to work in full-duplex mode.

Maybe I'm missing something? Any way to work around this?

I tried accessing Falconsat-3's BBS via PFS3-12 this afternoon, but I
wasn't able to connect. I'm using Easyterm with an experimental
full-duplex sound card modem by UZ7HO. This version has it's DCD
disabled to allow full-duplex operation.

Assuming the BBS is turned on, are there any special parameters needed
when using a simple terminal program? It would be nice to use Wisp
again, but I don't see a way to use a sound card modem with this program.

Thanks,

Tony -K2MO

FalconSAT-3 uses the PACSAT broadcast protocol which doesn't work like
a standard terrestrial packet BBS. A program like WiSP would be needed
to manage the process of sending and receiving files and directory
entries.

WiSP is designed for use with KISS TNCs via a serial port.
Unfortunately, it appears that Soundmodem's KISS mode uses a TCP
connection. I suppose a utility that could route the packets to and
from a TCP port to a virtual serial port might work.

Some of our Japanese friends have had success with both APRS & the BBS via
FalconSat-3. KO4MA has also figured out how to access the BBS, apparently.

I thought so Paul. I seem to recall someone posting something about Easyterm
-- guess it was used to simply monitor Falconsat-3 traffic.

All:

I'm told that there is a way to link a software modem to Wisp using
virtual comports and KISS modem emulation. The experimental full-duplex
UZ7HO's Soundmodem has a KISS port and I was wondering if someone can
guide me through the process i.e., how to setup Wisp's TNC port, which
VCP to use etc.

I already have Wisp setup for Falconsat-3, but it's been a LONG time
since I've used the program. Any help would be appreciated.

Thanks,

Tony -K2MO

Hey Tony!

Don't have an answer for you but I'm really glad to see your message. I
have been experimenting offline with TX through the UZ7HO high-speed
soundmodem using recorded FalconSat-3 9k6 data for my RX stream. However, I
hit a roadblock with the DCD... I could only transmit when there was no
incoming data detected, which is very rare!

As for your live, on-air testing, have you tried any APRS messaging
transmissions instead of attempting to access the BBS?

Thanks!

Same here...

I asked Andy (UZ7HO) about this and he whipped up a full-duplex version
of Soundmodem in a matter of hours. Works great with the DCD is
disabled. If you send him an email, I'm sure he'll send you a copy. His
email address is available on QRZ.

As for your live, on-air testing, have you tried any APRS messaging
transmissions instead of attempting to access the BBS?

Plan on doing that on the next pass!

Thanks Scott...

Tony,

You may be able to use the digi using Easyterm and High-Speed Soundmodem.

As Paul has said, you must use WiSP (or pb/pg) to use the PBBS. I no longer
have 9600 baud TX capability, but back in the AO-51 days, I was able to use
MixW with WiSP. MixW generates a virtual serial port KISS TNC, which can be
coupled to WiSP using virtual serial ports. MixW is $50, but you get a 30
day trial. Another possible program is Dire Wolf. I have never used it
that way, but the documentation of the latest version mentions a virtual
serial port TNC emulation. That is free.

I expect that many of those using the PBBS are using hardware modems which
support 9600 baud.

73s,

Alan
