Betreff: AW: LF: X1M Chinese QRP HF Transverter transmitting well on 475khz

Hello Warren,

Not a technical precise answer, but i did last night a quick WSPR test and the X1m 2min. transmission looked stabile on my primary receiver (see attached snapshot).

In addition i received WSPR on 474.2KHz with the X1m and my FT-857 in parallel both on Miniwhip antenna without any preamp. The FT-857 received abt. 3dB better. For exampIe I didn’t had a decode with the X1M when the FT-857 shows a station with -30dB. However not so bad the result for this small box. Will try it in the next days on 137KHz with a preamp and the miniwhip antenna on both receivers.

Hello Marco and Warren!

I didn´t  test the stability, but there is written in the manual: "The stability 0,5 ppm" 

Yes, I think the same, X1M might be useful for LF and MW activities. I don´t expect, it will be better than my "big receivers", but it is really interesting.

Marco, Lubos,

     Is the frequency stability good enough for QRSS or WSPR?

Hello Marco!

By coincidence - I received the X1M two weeks ago :-)

I haven´t tested transmitter. But  the receiver is not bad, indeed (...with an external input filter ,  of course).

> Received on the weekend the Chinese X1M HF-Transceiver. This Rig can transmit from abt. 0.1 - 30MHz, but has only bandpass filters on 80,40,29,15 and 10m band. So i tried 475kHz with a external bandpass filter and i got 5W in USB or CW (Not tried it, but this should work as well on 137KHz). In combination with a bigger PA a relativ easy way to transmit on the low bands.
