Hi friends radio amateurs!
Recently I received my mini-lime. Now I am deeply studying the topics of the forums. Thanks to reading, I managed to solve all the problems with my lime mini and was able to launch this board for reception and transmission.
I want to thank Eduardo separately for the SDRangel program!
(I scolded the author at the beginning of my journey, because at first glance it was very difficult to manage the program after simple and intuitive control pattern in PowerSDR from Flexradio and SDRSharp. Slowly I mastered SDRangel and understood the genius of the approach of Eduardo to writing a great program!)
I also want to thank Marty and Brandon for Eduardo’s support, as well as in consultations on topics of the forum for novice users of Lime and Mini-Lime transceivers. You are doing something important!
Now I would like to raise a few important questions that I did not find at the forums or whether these issues were scattered or did not have a solution for today.
- Use boar Lime/Mini-Lime for the needs of amateur broadband radio monitoring. To ensure maximum technical parameters, it is necessary to use bandpass filters at the input. I have the experience and the ability to develop filters. And I would like to know if there is a possibility of a software connection or selection of several filters in the future for a separately specified range of freq. (BPF for HF/27/50/145/222/350/430/900/1290/etc, Notch filter for 88-108/433/446/900/1800, etc.)
- As mentioned earlier in various forums, many of those who are interested in Lime / Mini-Lime can not fully use the card as a broadband QRP (or non-QRP) transceiver, since it is not possible to simply switch the reception / transmission (external PTT / tangenta key) , bypass, sequencer. Just like the lack of switching BPF.
Without the possibility of switching, the Lime/Mini-Lime board remain “flawed/restricted” toys for pampering in their spare time. Or simple arrangements with very limited functionality.
I welcome any thoughts and suggestions for implementation.
ps: I’m not a programmer, and I see no difficulty in creating software. I’m a simple Windows user and Linux.
But I see limitations in terms of RF design and final functionality.
Is there anyone here who could / would be interesting to implement the software functionality of switching BPF/HPF, PTT, bypass, sequencer?
pps: The hour of the sattelite Es’hali launch is coming to. The Lime/Mini -Lime transceiver is one of the few that you could use to transfer to 2.4GHz. For normal operation, it requires a ppt, bypass and amplifier.
