Charles G4GUO released an upgraded v1.25LP12 version of DATV-Express software that is compatible with the latest firmware from Lime MicroSystems. The Windows set-up.exe file and the NOTES file are now available at www.DATV-Express.com on the DOWNLOADS page. Many thanks to G4GUO for his efforts.
Ken W6HHC released an updated Express_DVB_Transmitter User Guide (Draft14) to emphasize that v1.25LP12 software for Windows has transitioned to cover four transmitter boards:
LimeSDR-USB (larger) board
This User Guide available at www.DATV-Express.com on the DOWNLOADS page.
Ken is currently working on revising the MiniTiouner-Express User Guide to include the new power supply options available with the addition of J3 in RevB version of the MiniTiouner-Express unit.
Draft 14 of DATV-Express Software User Guide has been revised to cover the ability to be used with four different hardware exciter boards.
Charles G4GUO has now received first-article blank PCBs from China for a 250-watt 2.4 GHz power amplifier design that he plans to use for uplink on the Es'hail-2 DATV satellite. He is just waiting for the heatsinks he purchased in order to begin testing the new PA. Also, he has just ordered a 1.8 meter dish antenna for his home Es'hail-2 station. He plans to use dual band feeds to provide both uplink and downlink functions.
Project Speed is set to slow….de Ken W6HHC
I have tested the F6DZP recommendation to use the PLUTO at 3457 MHz, then to send the signal to an SMA to guide transition.
I receive the H3 harmonic at 10371 MHz with a standard PLL LNB (OL 9750MHz) and the Minitiouner Pro tuned at 621 MHz.
Thanks to Jean-Pierre

I have a couple of questions...
I am using DATV-Express 1.25lp12 on my dual core Win7 laptop and a Logitech QuickCam Pro 5000.
I connected a LimeSDR mini and was able to succesfully transmit DVB-S, H.262 down to 187 KS/s. decreasing the rate I get a runtime error.
the first question is:
- is 187 KS/s the limit of the software or the culprit is my PC?
- how can I transmit a video clip instead of the TS from the webcam?
The only way to transmit a loop or pre-recorded video is to use vMix as an input to Express.
You can then use all vMix's features. The basic version of vMix is free but only supports SD (Standard Definition).
