Hello group....
I would like to understand the front end atchitechure of the Flex. I'm
talking HW here, not DSP.
Does it have hardware level roofing filters in the front end?
Also, how different in quality is the RCVR in the 1500 vs the 5000?
Thanks,
73,
Lee

Many, Many Thanks for all the responses. I really appreciate the inputs.
I've downloaded the PowerSDK and currently running it in the demo mode.
I'll continue to get up to speed and go from there. Thanks again.

Hi Martin,
One of the main differences between a Flex 1500 and the 3000 or 5000
is
that the 1500 communicates with your computer via a USB cable. The
3000/5000 both use Firewire, and they can be particular about which
Firewire
chipset is used. As far as putting a load on the computer is concerned
I
don't know if a Flex 1500 + PowerSDR software will put less of a load
on the
computer than a 3000/5000. There are people here who will know this and
hopefully they will jump in soon. I would try it on the computer you
have,
but be prepared to upgrade your computer to something more powerful.
Someone already recommended a quad core machine. That's what I did;
it's
sound advice.
You can use PowerSDR in Demo mode by downloading and installing it.
When
you run it without a Flex transceiver connected it will see this and
open a
window that lets you run it in Demo mode. I haven't tried this myself,
but
the capability is there.
Using RTTY should be no different than using PSK-31 or other digital
modes. The RTTY software will generate the tones and they'll be sent
to the
Flex as an audio input, just the same as PSK. It's all audio as far as
the
transceiver is concerned.
I can't speak to the CW latency issues, except to say that I hear it
gets
better with improvements in the software, and that the best way to send
CW
with no latency problems is to use an external keyer.
There are several amplifier options that will give you 100W output.
Unfortunately, those website links are on another computer and I'm
currently
at work. I'll see if I can get them to you later. I hope the rest of
this
helps!

Subject: [Flexradio] Newbie with some Questions
Good Morning,
I recently had to part with my radio and decided that this was a good
time
to bring my station into the 21st century.
I have a couple questions, so please bear with me.
At the moment, I'm leaning toward the Flex 1500. Reasoning: my
computers
are
old (Dell 530 and a couple of HP (with serial ports)). All the
computers
are
running XP SP3. I looked at the 3000; but that would necessitate
purchasing
a new computer. etc. I'm not sure I'm ready to jump that far into the
pool.
Question 1: I'm primarily a rtty contester/dx person. I've been
through
the
videos/faqs etc; however, I see no mention of anybody utilizing rtty
on
sdr.
PSK yes, rtty no.
Along this line, I also do cw. Reading the eham reviews, I noted a
latency
in cw operations. Some of the posts (reviews) were older, I was
wondering
if
the latency problem has been resolved in the newer versions of
PowerSDR.
Comments?
Also on the eham reviews, one poster mentioned that there was a "demo"
version of PowerSDR available for people to become familar with it. I
cannot
find it. Is it still available?
Question 2: I have a Ameritron ALS 600 amp available. I turned my
present
radio (IC735 backup) down to 5 watts and ran it into the amp. I got
45 -
50
watts out of the amp which I figgered was about normal. I would be
interested in a 100 watt amp to put behind the 1500. Are such animals
available? A 100 watts will do me just fine.
Basically, that is my first of many questions. I'm hitting the web
site
for
answers to most of them and the videos are a great help.
Any recommendations, etc are more than welcome to a new kid on the
block.
Thanks and 73
Marty
