many thanks for your help Tom.Have ran usb view and it says. device failed enumeration, unknown device.I take it that means i have a problem on the board..will...
Hi all, this morning I have decided to install Rocky in a new directory C:/Programs/Rocky35 instead of the default one C:/Programs/Afreet/Rocky ... and yes, it...
Hi Kees - have you actually implemented the BPF switching in hardware? I'm having the devil's own time with a relay scheme for switching them on my 8.3+Xtall...
Good morning, All Si570's and kits except those with CMOS chips and the most recent orders have been shipped. More CMOS and LVDS chips will be in next week so...
We are providing three binary bits to be used by a hardware BPF switching board. The three hardware outputs represent memory locations 100-199, 200-299,...
... What you have there is really neat, John - I am wondering if anyone has a hardware implementation of the BPF switching that will work with the Lite 8.3, or...
Hi Pete, Regarding versatility of BPF switching and enablement configuration did you checked this? -> http://groups.yahoo.com/group/softrock40/message/23712 73...
Pete, I have not implemented it but it has nothing to do with the frequency. It's driven by the memory (hundreds) bit selection. It's just a digital output....
By the way,. Why is so much difficult to join google.?? I see it must be approved by you but canīt see the reason why. All we see when we try to join is lots...
Jose, You do not need to join, you only want to download mate! 73 ... locations ... to select ... an add on ... like a ... my Lite ... works and ... get his...
Hi Christos - I don't appear to have a problem with controlling the switching, but the hardware switching seemingly introduces phase errors that exceed the...
Pete, Even better! This version has separate image calibration per each band. So when you calibrate lets say for 40m and then go to 10m the settings are...
Rocky also has band-specific I/Q balance compensation - the problem seems to be that the auto-compensation routines can't determine which is the fundamental...
Hi Jim, I had a problem trying to use a usb pen drive on my computer. It would not be reconized on one computer but would be reconized on my other computer. I...
Yes Pete, In PowerSDR is manual per each band so no such error can happen. I'm aware of Rocky's I/Q errors. Anyway both programs are there available to the...
Hi Pete, With the gain balance so far off it may be there is a soldering problem at U6, the FST3253. Please look carefully at the soldering of U6 pins 3, 6,...
Pete and Tony, Just popped into my mind. Sometimes so much deviation comes from sampling problems of cards. This can be rectified if you ommit one or two...
... Hi Pete. I also tried to switch the BPFs with a 3 pole 4 way switch and had the same problem as you had. I had a look at the outputs of the filter with a...
No, this is incorrect. In most cases, the front ports are merely connected to the motherboard USB connections directly, so they are full USB 2 ports. But, some...

Art, It may be that DELL has done those mistakes. I never found any 2.0 USB computers with the front port being 1.0. Regards. ... -- Jose Bonanca (CT1aos)...
... The issue is not that the front ports are USB 1.1, but that they are often provided via an internal USB hub. And some devices will not work properly when...
By replacing the DDS (AD9854)in my Flex clone with the SI570 gone are the annoying DDS spurs. Tony's new divider clock circuit was used as the interface. This...
... Getting rid of spurs, priceless! Good going, my SDR-1000 just ran out of warranty, that looks like a worthwhile mod.specially on 10M and 6M the spurs drive...
