SDRDataTransfer.exe v3.3.5 has been released & is available for download
from my website. If you are using v3.3.0 or later, you can use the facility
built into the program to download & install the new version.
The only change in this version is the removal of all references to the SVN
revision n
You need to verify that the USB drivers loaded properly.
Refer to this KB article

If not, you need to uninstall and re-install the USB driver (not PowerSDR)

Had 1500 running fine with SDR 2.05 on Vista machine. Downloaded and
installed SDR 2.07..now neither version will work. Both fail during start
up. Any ideas appreciated.
Thanks,

Let's do some quick math.
The change in frequency (delta F in Hz) is equal to (-) (Vs-Vr)/wavelength (a
close 1st order approximation when the speed of the wave is much greater than
the speed of the observer)
Vs is the velocity of source. For AO-51, that is about 8000m/s
Vr is the velocity of

Brian,
I believe that you will find that the Doppler shift is a proportional to the
frequency. Therefore, the shift at 432MHZ would be approximately 3 times
the shift at 144MHz.
A simple thought experiment demonstrates this. Assume you have a 144MHz
frequency source & it is moving away from t
You are right -- I should have been more specific.
My comments below refer to correcting for Doppler shift -- not for tuning the
linear transponder.

That would be a software feature for satellite operation and I do not believe
there is a plan to do it since you can get the functionality using third-party
software. You should add it to the enchantments list.

Don't make the mistake that Icom did in their IC-910, etc. where if the
432MHz band is tuned up 5kHz, the 144MHz band is tuned down also 5kHz.
The bands must tune in ratios of their frequencies, I.e., tune up 144MHz by
5kHz, the 432MHz must be tuned down by approximately 15kHz (use actual

I hope not Dan as I want to read about all four radios on both the
lists. It has been helpful to know what is going on the other radio
discussions to me.

Hello All,
Somehow I did not receive all your messages, but the last posting from Rick
contained all the missing pieces. I thank everybody for your input. A lot of
information to digest, and I will get back to some of you for further guidance.
Sorry for all my questions, but if you don't ask, you
You're right and makes sense to me. The fewer moving parts the better I
always say.

Most email clients allow 'Filtering'
I personally filter FlexEdge into it's own subfolder, and FlexRadio into
it's own subfolder.
No reason you can't employ a filter such as 'if subject or body contain
F3K, then' (insert what ever you want done with that email)

Hi Dan
The thing is that PowerSDR is more "radio" than the hardware hanging off the
end of the firewire cable so you are all using the same radio!
I understand what you mean though, with each new hardware introduction,
there is an initial flurry of emails on the reflector until the environment

this may seems lame or 'snooty' but here goes.
Is there any possibility the flex list could be segregated by hardware? i.e. a
separate F5k list, a separate F3k list, & separte F1.5k list ?
I'm guessing most guys just own one flex radio, and tire, as i do, of sorting
thru stuff that does not apply

Then do it. Tim provided you with the documentation to do it. It includes

I did this with a Flex-3000 and PTC-IIe some months ago. The signals you
need are on the Flexwire connector. It helps if you start with a cable
from SCS with the DIN connector already attached since these are hard to
solder. I found it quick and easy to do, and it worked exceedingly well.
