Took some time off to have a look at the X1M Platinum QRP radio last week. Did not get on air with it but just picked it up and mucked about with it a little. It is very small and the display is even smaller. No way to read it without glasses for me. The radio comes complete with a microphone and power lead so is ready to go out of the box. Has a built in speaker as well.

Operating voltage: 12.0 ~ 14.0V DC
Receiver Standby Current: 0.5A
Emission current: 1.5A Max
According to the specifications the device will receive and transmit pretty well anywhere but it can be made to stay strictly with in the 5 bands of operation. The radio seems to work quite well within the bands it was designed for and the CW signal on the scope below looks quite OK. Out put was about 3-4 w PEP.
But take it out of band and it is a whole new world!!! You probably won’t want to work the WARC bands with this baby.
Have not had it on air yet as no antenna suitable but it does have a lot of features in a little package. I think the 20w version they are bringing out will be the one to go for especially if they broad band it a little bit more to include the rest of the ham bands. Listening to A broadcasts will need to be in SSB mode and one wonders what the lack of filtering would do for the received signals. Might pick up a little more than was bargained for. More on that when we play with it some more.
