Posted on by

AESP-14-CubesatFirst Cubesat Developed in Brazil.

PY2SDR has confirmed the deployment of AESP-14 from the International Space Station at 14:30 UTC on Thursday, February 5.

The AESP-14 team would like to ask the help of the AMSAT community to forward any received telemetry frames back to the team. For this, please save the AX.25 frames in KISS format and forward the file to aesp14 (at) ita.br. Telemetry format can be found at this location: AESP14-Telemetry Format.

AESP-14 CubeSat
Frequency: 437.600 MHz 9k6 AX25

After launch we can use the TLE data from ISS.

New UZ7HO Sound modem version

Posted on by

UZ7HO has released a new version of his great Sound modem software.

UZ7HO Soundmodem

Here is part of the version history file, take a look at this file to get to know al the options.

SCM v0.71b changes:
- Fixed "Frame Collector" operation with MAXFRAME greater than 4 and IPOLL
  frames. By default it supports up to 6 frames into collector's buffer now.
- Added "TXFrmMode" option (that was available in 9k6/19k2 version). It allows
  to select the transmission mode of the frames.

  If set "TXFrmMode=1" then it will repeat only one frame on each of REJ acks.
  It can be useful in poor condition jointly with MAXFRAME up to 4. If another
  station uses a TNC which can operate with "Frame Collector" this option can
  improve a performance, especially on HF.

  If set "TXFrmMode=0" then it will always repeat the block of the frames, of
  which the number is limited by MAXFRAME. It can improve the efficiency in
  good condition. Especially with TNCs without "Frame Collector" function.

  By default this value is "1".
