Can you give us some examples of the weak signal stations
you receive on the R-75 with ECSS? What kind of antenna do
you use for these DX stations?
Thanks
DX'ing weak signals have just as much to do with "conditions"
as they do with the power and distance of the transmitted
signal. It may be very easy to get say...RNZI from my
location during times of the day and year when conditions are
good for it, and impossible to pick it up during other times.
I've used ECSS to identify weak carriers too but I was
wondering what you would consider a good DX catch. What have
you heard lately that you would classify as weak DX, given all
the "conditions"
Half of what I listen to is dx, including hams from around the
world. If you need a single example, I'll say .. How about right
now.... 21:50 UTC on 7.190 .... I'm listening to what I think is
Tunisia. Currently Arabic music. The signal is barely s-3 and it
is quite noisy. The same exact signal is also being broadcast on
7225. Still a bit noisy with fade out, but it makes it all the
way up to s-7.
I'd call this DX, but not a VERY weak one. It is far away, and
it is messy. The drill here on this signal is to use all the
tools at my disposal to clean it up and see how good I can get it
to sound... IE: ecss, filters, gain, nb, nr... etc.....
About S8 here on both frequencies.
Steve Holland, MI Drake R7, R8 and R8B
To be fair, though, Steve - that probably has as much or more to do
with your antenna farm (I've seen the pics and read your description
- it's terrific) as it does your reciever.
Steve does have good antennas but the Drake R8B is very sensitive. One
thing about different manufactures is their attitude toward
specifications. Some rate their product more conservatively than
others. Just something to keep in mind perusing the specifications
between different manufactures of radio equipment.
I don't think the difference between him picking it up on 7225 as s-8 and me
picking it up as s-7 is enough of a difference to base it on his receiver
being more sensitive. It is hardly any difference at all. If I checked
the meter ten seconds later, mine might have been at s-6 or s-9 the way it
was coming in and out.
One real question here... And one that I'm interested in.... Why would I
get it on 7190 at only s-3 while he gets it as s-8 ??? We're both getting
it about the same strength on 7225, so why should we be getting such a
measurable difference on 7190 ??? I'd say it probably has more to do with
the peculiarity of our locations in respect to the transmitter and what ever
comes between them rather then our receivers.
