QRPver pocket sized transceiver review

The QRPver is a US$80 1W QRP transceiver that is perfect for running digital modes such as PSK31. It connects to a computer via analog audio cables and has internal VOX so there's no need for an interface box or serial rig control.

It's about the size of a pack of cards as you can see in the photo on the right. 

I'm using it with Fldigi running on Fedora with a generic USB audio dongle. I did need to use the Sound application to increase the audio level a bit to get the VOX to trigger when I transmitted.

Note that the audio sockets are stereo sockets with left and right tied together so you do need to use stereo leads or you'll short audio to ground.

I ordered my QRPver for 14.070 (there are a range of bands and frequencies to choose from). 20m PSK31 was very lively a few years ago but at the moment seems rather abandoned for some reason, perhaps everyone's running JT65?

First contact was pre-arranged with Stephen, VK2BLQ who is pretty near by. Today VK5WOW popped up being operated by Grant, VK5GR who made a few comments about the signal not being all that clean and also it drifted about 20-50Hz during a longer over.


The QRPver draws just 20mA on receive and 650mA or so on transmit so it would be great for portable digital operation. The receiver seems sensitive enough and while not a perfect signal on transmit - something that might be because I need to tweak the level a bit or possibly there's some RF getting in to the audio - I think it's a great gadget for the travelling ham.

Be interesting to try FreeDV on it.....
