The QRPver-1 v3

The QRPver-1 v3 is the new transceiver made in Ukraine by Yuriy Viktorovich Hubernatorov, UR5FYG, an excellent OM and engineer. QRPver Electronics is his site and represents a group of Odessa comrades radio engineers, have been developing and manufacturing a variety of radio.

As you see in the video The QRPver-1 v3 is really microscopic and easy to manipulate. We haven’t test yet but we look forward to it.

The website states that “this transceiver is built on the scheme with a single superheterodyne frequency conversion and four Crystal quartz filter. A micro controller is able to control everything you see on the display. The frequency synthesizer used as a local oscillator on-chip SI5351. USB/LSB and CW are available as well the digital modes (FSK PSK RTTY)”


The QRPver-1 v3 has following characteristics:
Two AGC mode (Fast / Low)
Vertical / semi-automatic keyer
Enable / disable the transmission of AF signal at the input.
For digital modes (DIGI-VOX)
The offset frequency for CW
Self-control for CW
Lock encoder
Indication of low voltage

100 mA while receiving
700 mA in transmission mode
Receiver sensitivity better than 0.4 Microvolts
Transmitter Output Power 3 W nominal. (4W on 20 meters and on 10 meters band)
Low-pass amplifier Output Power 0.7 W
Intermediate Frequency 9 MHz
Band crystal filter bandwidth 2.9 kHz at -6dB
Carrier suppression more than 70dB
Suppression of non-operating side, more than 70 dB

Only 180$ – 150euro. We believe the ham radio (QRP) is very affordable now with this tiny transceiver. It’s not the usual chinese one, we really can trust UR5FGY and this group of engineers from Ukraine…

Now available. This is a QRP 5 watts only HF transceiver 0 – 30 Mhz. It’s an open source Portable HF SDR Transceiver made by Mike Colton (KE7HIA). Named the PSDR. Ah, I forget: it has also 144 MHz band. The transceiver base his force on the CPU ARM 168MHz, colour display, and an innovative interface. Vector Network Analysis (which includes antenna analysis) and GPS functions are included.

The PSDR radio recently won 3rd place in the 2014 International Hack a Day prize competition and has now launched over on the Kickstarter crowdfunding website with the aim of raising $60,000 to make the jump into manufacture.

Michael colton in his last interview, declared: I’m an avid backpacker and radio enthusiast. To me there is something exciting about making contact with others from remote locations where cell phones and the internet can’t reach. I wanted an advanced radio that was ideally suited to tough environments.

That meant I it needed to be very compact, integrated, and durable. As an engineer, I wanted an open platform that really takes advantage of the hardware and has the potential to grow and be used for other applications.

There are numerous, excellent radios out there, but none offered the combination I wanted. The best radios are closed source, larger, and expensive, while most open designs are very basic and lacking in flexibility.”

… soon available. 

Available on the market since next Spring. Be aware this is a “beta version” with only few milliwatts as output. Speakers, not functionally working. Next step, Michael said, will be to increase power up to 4 watts at least.  Click down here on the arrow to see a full complete review on PSDR HF transceiver 🙂
