Full SDR receive with G4HUP buffer amp

SM0JZT has installed a  G4HUP buffer amplifier in his µBITx and uses an RTL-SDR dongle externally.  This is an alternative to the approach used by KD8CEC to add an RTL-SDR that gives much wider bandwidth (i.e. the bandwidth is not limited by the 45MHz filter).   The G4HUP buffer amplifier can be purchased here in either fully built-up form or in kit form.  Order the 50MHz unit is what you need (it has an LPF above 50MHz and requires no modifications to work on 45MHz).

This gives you the best of worlds – a low-cost transmitter and an equally low-cost SDR receiver.   Thanks to SM6MOJ for bringing this to our attention.
