With SDR presumably this is best used with PDSR and VAC. It does not seem to
have an I/Q mode?
Like here http://www.yt1dl.x50.cc/sdr3.html and
http://sites.google.com/site/g4zfqradio/softrock-wspr-psdr-and-vac for WSPR
substitute Digipan or any other digimode.

Thankyou everyone for your comments.
The VSPE solution seems the best option, sadly it does'nt run on '98se but I
can't have everything can I :-)

you look under CFG (lower right hand of the screen) in the IQ box, there is an
IQ balance box.  I've never gotten that to work well for me though.

Hi !

Are there any members of the group who know the max frequency of
fst3251 ?

I just received a jiffybag containing a couple of samples from Si Labs
of their new Si0104 chip.  Haven't had a chance to do more than skim the
datasheet but I think they could be useful in simple direct-conversion
receivers.

Basically the Si0104 is a frequency-sensitive AND gate - you feed in an
"unknown" signal and a reference signal and if the two match the ref
signal appears at the output.  One example is using it with one of the
Si570 DDSes to compare a wide range of frequencies.  It's not a great
leap to see how you could make a very sharp CW direct conversion
receiver by sticking a tuned RF amp on one input, and modulating the
reference oscillator so you didn't have to be bang on the received
input.  You'd then get the ref osc pulsing on the output at the rate you
modulated it - say, 700Hz for a nice CW tone - and none of the noise!

I'm looking forward to getting a chance to play with these.  The Si0104
looks like a very useful wee part.

Hi Flemming,

You can check the datasheet, it specifies something between 6.0ns to 6.5ns on
the switching so it seems that it can go around 180MHz (/4 = 45MHz VFO)

Why do you ask others for something that you can find easily on your own?

Hi sv1eia
 
Datasheet is a god thing but it,s  not always that the data stays with in the specified field.
 
Eks. si570 cmos , says 160mhz but I have one there works very well on 250mhz .
I am  making some mods on the mobo 4,3 for the uhfsdr from wb6dhw . ( when it arrivals ) transformers ,Pa,ect .  The uhfsdr is finnish and works very well.
 
One linie to the mobo and one for 2m , but I hope that I can have 4m-6m runnning on the mobo . Maybee also 2m.
 
It,s good with some info from some one , there  have been playing with it in praxis !
 
Best regards Flemming / oz5agk

Hi all,

Mario, DG0JBJ released a new version of his WinradHD program yesterday, now
v0.151.

http://www.hdsdr.de/index.html

Enjoy!

Good Evening All,

I recently received additional circuit boards for the Lite II kit family and the
v6.3 RXTX kit.  Also circuit boards were received for the v6.3 PA/Filter kits.

v6.3 RXTX kit open orders are now being filled and I should be able to catch up
on all open RXTX orders by early next week.

Thanks for your kit orders and patience with the delays in my kit shipments.

73,
Tony KB9YIG

Good Evening All,

Beta testing is going well on the RXTX Ensemble kit but I would be interested in
getting a few more testers involved.

Minor changes were recently made to the RXTX Ensemble circuit board to get it to
what I believe will be the production configuration.  I have four RXTX Ensemble
boards coming in Wednesday of next week for pre-production testing of the kit.

I am wanting to offer four pre-production RXTX Ensemble kits at a reduced price
to four people who have the interest and time to build the kit and report on any
issues found while building and testing the kit.

The pre-production kit will contain all parts that will be provided in the
production kit so that the kit may be build for operation on one of four band
groups: 160m, or 80m/40m, or 30m/20m/17m, or 15m/12m/10m.  The price of the
pre-production kit is reduced to $50 per kit which includes the postage.

Please contact me if you have an interest in building and testing an RXTX
Ensemble kit.

Thanks and 73,
Tony KB9YIG

Is there still a final run of 50 RXTX kits up and coming, or have those already
been sold out?

Thanks for all the hard work, Tony!

I brought this up before when the last version of SDR-radio 1E came out early in
March and I was wondering if anyone had similar problems or any ideas on what
the heck is going on.

It sounds like all signals have intermod or severe overload and distortion. I
reloaded version 1D and it now does the same thing. It did not before. I would
think I had a problem with my sound card or hardware but every other decode SW I
have tried, PSDR, HDradio, etc. works fine. The only one that exhibits this
behavior is SRD-radio. I am using an EMU 0202 USB and turning the volume
controls fully down makes no difference other than changing the absolute levels.
I had thought that going back to the 1D version would return me to a working
copy but it now does the same thing. Any thoughts or ideas would be appreciated.

I am sure many in this group had this or one of the hundreds of computer models
of the late 1970's. For me it was Digital Group. Wow we thought we were hot with
64K (yes K) of memory and that 10 Meg hard drive that cost a thousand dollars or
more was really a luxury. Oh the good old days!

I got an Altair in 1976.  It was a kit for "only" $1200.  Got it at
"The Computer Store"  on Olympic Blvd in Los Angeles.  The Computer
Store was the first personal computer store in the country!  Came with
8K of RAM, no hard disk or floppy.  I used a reel to reel tape recorder
for program storage!  Loaded at the fantastic speed of 300 Baud. That
was after you hand keyed in a 21 step bootstrap program with the toggle
switches on the front panel.  Came with Altair Basic(took 6K of the
8K).  If you displayed the bits as ASCII on the screen of the TV
typewriter used as a display, near the end you saw "written by Bill
Gates and Paul Allen"!  It was in a kit, all parts had to be soldered
onto each plug in board and the motherboard(which, I think, was 8 slots)
had 100 contacts for each board that had to be soldered!

Question 3
May I change scale of frequency in spectrum frame ?

I got this Si570 from Jan G0BBL, last year and I find I don't need it for now.

It's new in the packaging from Jan, G0BBL.

Marked:  Si570BBB000141DG

I will take $65.00 US Dollars for it for delivery to anyone in the USA.  This is
about the same cost that I paid, no profit here.
