A sound card as a receiver. Pick Sound card in Source and choose your card: a mono card becomes a receiver from 0 Hz up to half its sample rate (0 to 96 kHz on a 192 kHz card), which is what VLF listeners feeding an antenna into a sound card need; a stereo card can be read as I/Q with the centre frequency you type. On Windows the list shows WASAPI inputs, so the rates offered are the ones the card really runs at. Changing the card's rate, channel or format while it runs now works even in exclusive mode, and if the card refuses the new settings it goes back to how it was. After plugging in or unplugging a card, restart FoxSDR.
A BIAS TEE key on the main panel. When the open radio has a bias tee, a BIAS TEE key appears under the MASTER lamps. Its lamp shows what the radio reports. Switching it on asks first, because power on the antenna cable can damage equipment that is not expecting it; switching it off is one press. It does the same as the Bias tee checkbox in Source.
The bias tee is now remembered for each radio separately. Earlier builds kept one setting for every HackRF, Airspy, SDRplay, Mirics and RX888 radio, so switching it on for one could power another. If you use a mast amplifier on one of those radios, switch the bias tee on once more after updating; from then on FoxSDR switches it on again whenever that radio opens. RTL-SDR settings are carried over.
Not yet tried on the hardware. There is no suitable sound card or bias-tee amplifier on this desk; both were proved against faithful software stand-ins. If something behaves differently on yours, REPORT A BUG / DISLIKE reaches us directly.
