QRPver-1 Monoband QRP Transceiver anyone?
The QRPver-1 is a QRP monoband transceiver the size of… a power bank. This is version “3” and I believe it is the backpacker’s dream. At around 200 grams, you’ll get to the summit easier. If you care about SOTA anyway 😉 and don’t mind having only one band.
The transceiver is built with a single superheterodyne frequency converter and 4 crystal quartz filters.
Here are some specifications from QRPver’s website:
Power supply in the 10-14 (13.8 Nominal)
Current consumption in receive mode with an average volume of 100 mA
600-800 mA in transmission mode (mean 700)
Receiver sensitivity better than 0.4 Microvolts
Transmitter Output Power 3 W nominal. (Max 4 W)
Low-pass amplifier Output Power 0.7 W
Intermediate Frequency 9 MHz
Band crystal filter bandwidth 2.9 kHz at -6dB
Switchable LP filter (200,300,600,900,1200,1500,1700,2000,2200,2400,2700,2900 Hz) with a fairly steep slope.
Carrier suppression more than 70dB
Suppression of non-operating side, more than 70 dB
It supports both SSB and CW and the maximum output power is 4W. The cost is $180 and you have the option of selecting the band you want it to come with. You can download the manual in Russian here. At the time of writing, I couldn’t find a manual in English. Schematics and everything are included though.
