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.

475khz
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).

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.
