WSPR in Linux

I'm typing this from Linux Mint 17.3, while running WSPR. It was quite easy to install the Windows version of WSPR 4 using Wine. The only problems were no choice of sound devices (I have both internal and USB audio, often a different radio application is using each one) and the list of serial ports for CAT control of the radio still showed COM1 etc. which don't exist in Linux. I think these can be set up to use the proper device but I just chose VOX to transmit.
When I was installing Linux Mint I chose to install it alongside Windows, and it installed itself on an external USB HDD (with the boot menu on the internal HDD).
You can see on the screenshot where I had to turn the input level up from its default of 0. It still managed to decode 2 stations with only half the time slot though.

DMR

Everyone else seems to be getting DMR equipment so I thought I'd get one myself - a Retevis RT-3 UHF handheld. It's a clone of the Tytera MD-380 and one of the cheapest, at under £120.
I've used it on my local repeater GB7MB (Heysham, Colour Code 1, 439.700 MHz) and also simplex where there is quite a bit of activity on 438.5875 MHz round the Barrow-In-Furness area.
I've not been much of a repeater user but I like the way you can see the activity on any repeater using the DMR live monitor

I can also receive a few other DMR repeaters at home:
GB7PN 439.425 Prestatyn (2nd best)
GB7CA 430.925 Douglas, Isle Of Man
GB7TP  439.6875 Keighley
