Mike,

The specs are as follows:

3.3V LVDS
20 PPM

10- 945 MHz
970- 1134 MHz
1213- 1417.5 MHz

Two of them have been spoken for. I may have one or two

more...will

"Blessed are the cracked, for they shall let in the light."

I can't seems to change the frequency on my v9.0. It seems to be stuck
on 20m, probably around 14.100Mhz. Changing frequencies, on both
Winrad and Rocky, has no effect on the spectrum, though the frequency
displays on the program suggests that the changes were made.

Using Si570_USB_Test, Read Si570 Registers produces:
Registers 7 to 9= FF Hex
RFreq=10233.999
N1=127
nN1=128
HS_DIV=7
nHS_DIV=11
freq=83.11636

Attempting to change the frequency using "Set freq by value" does not
produce any changes to the register frequency.

Any ideas as to what might be happening?

The radio itself seems to be working. I received 20m signals from CQWW
last weekend and the RTTY contest today.

HI Jim,

Yes, paypal is okay but please add $1.20 (3%) to cover the fees. you
can send to my e-mail address mattpatt at 1starnet.com.

Sorry it took so long to get back to you. I subscribe to the digest

A beginner's queston to WB5RVZ and other experienced builders.
I'm waiting for Si-570 to be delieverd in mid December.
May I bypass the LO stage and go further with Dividers-RX OpAmp -
RX Mixer. Will this influence the tests (current, voltage) results?
Or shall I be patient in order to succeed in building&#92;testing the kit?
Please pardon my asking if this has already been asked and answered.
Any suggestions on how to proceed would be appreciated.

I have added pull-up resistors to the I2C lines from the 5V rail.
It seems to have solved the problem.

I think this "alan hardware patch" is the easyest way. Re-programming
the chip is not that simple since it has reset-disabled, means ISP
programming wont work.

That is if you need this patched at all, since observing the switch-on
sequence the original firmware does always work.

------

I got my firmware patched only because i like to play with those
things. The programmer did cost me a 100$. In the meantime i had the
code running on a attiny44 (needs external crystal), then an attiny26
(no crystal, but only 2kb flash). Waiting for a attiny461 chip now,
which will allow a no-crystal operation and has lots of spare IO pins
for bpf, cw-input, tx-signal, tx-swr reading etc, maybe even a blue
usb-activity led ?

Good Afternoon All,

I have the following kits returned to me in recent weeks.

Joern Noergarard Christensen, Broendby, Denmark (two padded envelopes
returned)

Takanori Sugihara, Tokyo, Japan (two padded envelopes returned)

John Long, Sandy, UT, (one envelope returned)

Brett Graham, Hong Kong, (one padded envelope returned)

Hrafnkell Eiriksson, Kopa Vogur, Iceland (one padded envelope
returned)

Please contact me so that I can send the kits again to the proper
address.

Thanks and 73,

the sdr3000 has firewire, NOT the sdr1500

I have also ordered a 1500 for delivery in Feb but plan on using a

I already have which has a firewire interface.

I bought the acer last week, mainly to run my sdriq and sdr1500
(when released) "in the field". I ended up paying under $250 in
a "black friday special" with 120G hd and 1G memory. I have tried

it

with the sb extigy external usb sound card and it works well with
the 3 sdr applications i use (KGK, powersdr and Rocky) I also

tested

it with the hpsdr and it works well

Do not think of buying the flash ram version and trying to upgrade
to a HD later, unless you have VERY good motherboard soldering
desoldering skills, the ram is soldered to the board NOT
connectorised

There is a very useful "user" web site on this computer


I did look at the asus version, but I wasnt convinced the cheaper
looking keyboard would last field operation

Hmm. I lost all email from Yahoo Groups from 5:34 PM last evening (DST) till 5:09 AM today. Maybe it was nothing you did?

Hi Jose,

I think many people did patch the firmware, i also modified the firmware from DG8SAQ. My modified firmware will initialize the si570 when it comes on line. But I change more in the firmware to play around. I do not know what Tony plans to to with the firmware for new shipments.

Hi Christos,

Great! Thanks for the info. The Mobo v3.5 is in Beta now and this
will give the builders more options to do the band switching :-)

Good Morning All,

Seventy-five CMOS Si570 devices were mailed today< December 6, and
another 25 will be mailed on Monday, December 8. This group of Si570
devices cover kit orders received by me on or before October 28. The
next group of 100 Si570 devices should get to me by mid-December and
will cover kit orders through the end of November. December kit orders
will be covered by the 100 pieces of Si570 due in the first week of
January.

A new order of v9.0 Lite+USB Xtall circuit boards and BPF circuit board
were shipped on December 5 and should get to me by the end of the day
on December 9. Additional v9.0 Lite+USB Xtall kits and v6.3 RXTX+Xtall
kits should be mailed to kit buyers on December 10 and beyond.

I will try to get additional HF BPF kits mailed early next week to
people who ordered HF BPF beta kits. These kits will have what will be
the production board except I will saw the boards out of prototype
panels. A production quantity of the boards will go on order after
some initial tests with the new board configuration.

Thanks and 73,
