X1M QRP Transceiver from China.

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.

2 knobs on the front and 5 push buttons to access the various functions. The rear has the pl259, power plug, headphones, key, and a plug to connect to a computer!

Specs as supplied:
Frequency range RX & TX: 0.1 ~ 30 MHz*
Modes: USB & LSB & CW
Power output: 5 Watts
Operating voltage: 12 vdc
Operating current: 0.35 ~ 1.2 amp
Receiver Preamplifier: Yes
Memory Channels: 100
RIT Function: Yes
Automatic Internal CW Keyer: Yes
Backlight On/Off: Yes
Keyboard lock: Yes
Dimensions: 3-13/16 x 1-9/16 x 6-1/8 inches
Weight: 0.65 kg ~ 1.43 lbs
PTT Microphone: Included
Computer Control: Compatible with Ham Radio Deluxe
(factory adapter required – Choose Icom IC-718 in HRD)

* Transmits continuous 0.1 – 30 MHz
(except US Broadcast 0.55 – 0.17 MHz & US CB Band 26.960 – 27.410 MHz)

Five Ham Bands are configured with bandpass filtering. Transmitting on frequencies outside these ranges may require external bandpass filtering.

Band 1: 3.5 ~ 4.0 MHz
Band 2: 7.0 ~ 7.3 MHz
Band 3: 14.0 ~ 14.350 MHz
Band 4: 21.0 ~ 21.45 MHz
Band 5: 28.0 ~ 29.7 MHz

Receiving sensitivity: better than 0.45uV,
RF output power: ≥ 4.5W
Frequency stability: better than 0.5ppm
Frequency accuracy: better than 0.5ppm
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.

    Thanks Dave,

    Does it really not TX between 26.960 – 27.410 MHz?

    Cheers

    Thanks Dave. Time will tell!
    I look forward to seeing how this radio goes in some “on air” tests. It is great to see China finally producing some interesting kit, that is not the usual (boring) 2/70 FM stuff.

    Best review at the internet on this little RTX till now Dave. Keep us informed! 73, Sebastiaan

    Reblogged this on VA3QV's Weblog and commented:
    It seems we are going to have a new toy to use for QRP HF. If anyone has any info or comments on this one feel free…

    How much does a transceiver?

  6. Paul says:

    Hi all, I have owned the X1M tranceiver for a few weeks now. I purchase it for portable work. It is light weight and small, works well and I have had good signal and audio reports from the 5 watts on SSB. The output power does drop as you go higher in frequency and at 10 metres it is down to between 1 and 2 watts. The inbuilt keyer is not well designed and is hard to produce good morse with. Plugging in an external keyer works well with good reports. The internal menu allows setting for most functions required. There is no signal strength metering. Overall I am very happy with the rig and looking forward to when my 10 Ah Li-Po battery arrives so I can go backpack portable.

      We bought 5 of them and had problems with 3 of them.
      Dry joints and the antenna connection it seems.
      While they respond quickly when you want to buy them there is an awful silence when we asked for the address so we could send them back for repair!!
      The output on the higher bands is indeed very low.

    27.215 fm ?

  8. Russ says:

    Thanks for the information here. What type of power supply iare you using. Will a standard wal wart with the correct voltage work?

  9. Loren Coty says:

    I am looking for one of these radios, used or new, from someone in the US…If anyone has one, please contact me (It says I will be notified of any new posts to this forum). Thanks so much,

    Sorry, this radio has a lot of problems with linearity of PA, with keying (autospace switch on?), with clicks and so on. I do not recommend for traffic.

    I have X1M older version which receives 7269 KHz at 16269. Most of the bands are pretty much off the frequency. Prefer if some one could repair in US or Canada. Would like to have their address in China. Thank you.
    73, Khan

    • dd182003 says:

      Yes..the problem with buying these type of radios is that they become throw away when something goes wrong. It will cost you US$150 in courier fees to return the radio to China and then back to you. Even if the repair is free I don’t think it makes it worthwhile…
