Direwolf Vs QtSoundModem (part 2)

Okay, that was a bit of a disappointment. I ran the test at 14.1022Mhz on 300 Baud. I think the conditions were very bad in those 24 hours.

For the test I use Kissutil.

kissutil  can be used interactively for troubleshooting a KISS TNC. It is usable with direwolf and other generic KISS TNCs connected to a serial port. It can also be used as an application interface where each side places files in a directory for the other to process.

First I wrote two start files for the test.

Direwolf.sh

#!/bin/bash
cd /home/niels/testbed/
./kiss-direwolf -p 8009 -o /home/niels/testbed/rec-direwolf

Qtsm.sh

#!/bin/bash
cd /home/niels/testbed/
./kiss-qtsm -p 8105 -o /home/niels/testbed/rec-qtsm

The test ran for 24 hours, which is 86400 seconds.

timeout -s 9 86400 ./qtsm.sh

After 24 hours I can start counting the received frames.

As you can see this is very disappointing. Now I understand that the focus of QtSoundModem is more in the HF area. With a difference of 4 frames, the difference between Direwolf and QtSoundModem is minimal. In fact, too few frames were received in the 24 hours to make a good comparison. Is my opinion.

The next test we will try on 144.800Mhz the local Aprs frequency.

  1. Hi Niels,

    Had my first foray into IL2P yesterday. Got QtSoundmodem for Windows working. with my TS-590S after editing/recompiling rigctld (TX vs TX1 issue). Didn’t see anyone on 20m so I left it on overnight and checked today. Copied you! (see below).

    So now over a year since this article, which program are you using for HF IL2P?
