Small QRP single-band transceiver QRPver-1 SSB / CW / JT65 / prostitute / BPSK / FSQ
What a cheap QRP transceiver for one HF band? The answer may be QRPver-1. It has dimensions 103 x 30 x 75 mm and weight 350 grams. It is structurally a superhet with one intermediate frequency with a crystal filter. The control is a microprocessor. The oscillator provides the popular SI5351 circuit.
This is how QRPver-1 behaves in the SSB league

Block diagram QRPver-1 v.3
The tiny TCVR is capable of LSB / USB, CW / SSB / DIGI operation. AGC is switchable. Thanks to microprocessor control, the display shows the frequency, mode, filter width, tuning step or S-meter. A semi-automatic elbug will also please. The offset for CW is adjustable. In portable operation, you will also appreciate the low voltage indication.
The current price of QRPver is 190 dollars. It is not a TCVR of top parameters, but a really tiny device for occasional operation. To be purchased through https://qrpver.com/transceivers/qrpver_1_v_3.html, where you will also find user reviews, more photos and videos.
