@waldemar - Waldmar,
Adrian is right, I have been pursuing the LimeSDR effort since the very beginning (going on 2 years now) as the core element to a QRP, or for that matter, standard Amateur Radio equipment with 100W output capability (once you add the driver PAs and the Lowpass Filtering required for that). From all the time I’ve been associated with this LimeSDR effort I’ve had a fair amount of time to evaluate it for how feasible it is to make this a foundation piece for the Amateur Radio service, and I’m here to say this: It is feasible to implement the LimeSDR to be a wideband radio for Hams (160m to 23cm).
Having said that, it isn’t without some work that it can make such a transceiver. There’s a fair amount of filtering for the PA, preselection for the front end and some preamplification that’s necessary to make this a workable rig, but that’s not a very vaunted task to achieve, and for what it’s worth I’m working on that as I type this. I would hope that by sometime this summer I’ll have a companion board to do all the PA filtering, receive preamp and preselection as well as I/O for controlling external antenna switching employed over the whole range (160m to 23cm).
Continue to express your thoughts here, Waldmar, because that’s the end-game for me…Making the LimeSDR a very important part of a great wideband rig.
