[Lowfer] SDR Receuver

[Douglas D. Williams]

Hello again Jerry. I believe we "spoke" on the LWCA message board.

I finally made the decision to purchase an SDR and bought the Winradio
G33DDC "Excalibur Pro". I've only had it since yesterday, but so far I am
very impressed. It seems quite sensitive all the way down to 10 kHz, and
the frequency stability is rock solid at even QRSS120. It is actually THREE
receivers, independant in all settings.

Earlier today I posted a pic of an ARGO screenshot of Mitch Powell's beacon
"MP" running QRSS30 on 137.781 kHz. He is about 500 miles from me, IIRC,
and this was a daytime copy.

It remains to be seen if the G33DDC is as good a receiver on LF as my R75 +
Todd Roberts converter. That is a hard combination to beat. I wish I had
some sort of "splitter" so I could use them both at the same time with the
same antenna, for an A/B comparison.

I've been playing around with the software all day. I am receiving many of
the military MSK transmissions in the 15-40 kHz range, including Australia
and Europe.

I'm hearing many airport beacons in the 190-500 kHz range.

The noise blanker does a suberb job against my neighbor's electric fence.

One thing I don't like.....the receiver turns off whenever you exit the
software. This is only an inconvenience for modes that require extreme
frequency stability, such as QRSS, because the receiver has to "warm up"
again for a few minutes before it adequate frequency stability.
