Regarding the need for something to monitor transmissions from the Bitx40v3 during testing,
the SoftRock Lite II Combined Receiver Kit at $21 might be the best bang for the buck,
assuming you already have a computer with appropriate sound card: ?
Feed a 1khz tone at 50mv or so max into the mike input, zoom in on the computer monitor
to check the suppression of the carrier and opposite sideband. ?Should see a single peak.
A two tone audio signal into the mike should show two peaks, as you turn up the injected 2 tone audio signal
and/or R136, additional nearby peaks will start to appear indicating distortion.?
But most any SW receiver capable of hearing 40m would solve the immediate issue for the original post in this thread.
Even the $1.98 pixie.
