Re: Proposed upgrades to RSP1 no cancelled ??

Hm, I would say most of the wishes for the RSP 1 have been recognized and the result is the RSP2. Only thing I don't like with the RSP2 is the high impedance antenna input for VLF and LF. I am using an active antenna there which has a 50 Ohms output. So the recent buyers of the RSP1 have funded the...

Re: Saving Workspace

The only frequency stored is the VRX#0 frequency. We will be addressing this in a future release.


It would also be useful if the modes & filters were stored too.
