Hello Chris Can you give me some more information about the error message, and what steps you took before the error message appeared? With no latency. I think the problems are with Windows 7 — 64 bits.

July 26, at am. Hello JM. If the problem still persists, I am of course happy to offer a replacement. July 27, at pm. July 28, at am. Hi Howard, Thank you very much for your patient and explanations. The problem was a defective Usb cable. I replaced it and the receiver works fine.
Regards, J. July 30, at pm. Hello J. Glad that worked for you. July 31, at am. So I installed Xcode from the Apple dev site, and that fixed it immediately. Hi Howard I registered as a Mac developer and downloaded the Xcode 3. That cracked it. More midnight oil to burn I guess.
I have no idea how many PC keystrokes it took him to get itgoing, but eventually it did and we were delighted with initial results. We are sorry for the inconvenience. Now — considering using WRPlus. However — how does one establish which firmware version is in my FCD?
Must be 18c. Reading the Firmware Update Guide I see no reference to the actual current version nor the version which is about to be loaded. Advice please…. Thanks for your note. The firmware update guide was written before we introduced firmware numbering.
To determine whether it is 18b or 18c, imediately after insertion, start Spectravue if you can! Later versions make it easier. These are the other possible strings for that fourth line in application mode:. The firmware is distributed unzipped, you just need to open the file in the appropriate folder where you downloaded it.
Please Howard, May you add a date of the release to all the files , in the download page? Just the same as is for the WRPlus download. It would make it easier for the end user, I guess. We are making an integrated observatory for radio and optical observations, using a variety of hardware. The FCD offers an opportunity to make e.
Happy to help here if I can, you might find it easier via email though. Is there any instalation guide? Iv never worked with SDR. I need tes from getting the FCD…. Hello i am using the funcube dongle with spectravue but cant get the demod option to work any idears. Not sure if you have followed the documentation in the downloads section, but if you email me some print screens of your settings I may be able to help. Recently I have been trying to do a sale on Tuesday each week, but we have had some delays over the past couple of weeks procuring parts due to the tranche of no fewer than four public holidays in ten days here in the UK.
As soon as I know I will confirm it here, but it will be as close to next Tuesday as we can make it. Just wondering how one sets the sample rate as I seem to have only Given the right software?? Is there a special configuration to increase sensitivity?
I have updated the firmware to v18f and tried to play with the parameters on the FCHid control software. Can I do some thing elese to improve the rx performance? I suspect that you may be seeing some receiver blocking from some other signals.
Typically people have been adding front end filtering to improve this. However the front end filtering on VHF in particular can block. I strobgly suggest using a USB extension cable on the FCD to separate it from the PC particularly if you are encountering the situation you appear to have. I have experienced the same problem here.
Reducing the gain helped a lot. A tracking filter would have been ideal, but I imagine how difficult it is to include such a functionality in a tiny USB dongle. Otherwise, everything is working OK.
I see that the trick is to set the initial 20dB for the LNA to a lower value e. Thank you!! I received my FUNCube Dongle today and am looking forward to getting a chance to write some code for it. Quick question: Is there a HID command i. There is no harm in upgrading or downgrading to and from different firmware versions. Are the dongles all functionally tested before shipping? I just received mine and updated firmware to 18i.
Using Qthid and iSpectrum on Mac. Scanning the bands, I get nothing but noise or the occasional birdies… Nothing like the videos other users have posted on youtube. No joy. Possibly a bad dongle?? Things are looking better now. After attaching a real antenna, and downloading some better software DSP Radio 1.
OK, any further problems please let me know. You might find it easier to email me screenshots on my Paypal account. I have written up a small step by step tutorial about how to upgrade the firmware of your funcube dongle.
Hello , I recently got the Funcube , it seems to work fine , the background noise with 50 Ohms at the input is a little high dB with spectraview, not about dB as mentioned in the manual. As I had planed to use it at to MHz as the if reciever for my 8. I read in the faq that there is a locking problem. Is there a chance that this will be fixed in the near future? Regarding the dB, this can be a little misleading as this is a figure designed for relative measurements rather than being an absolute measurement.
It is also of course dependent on what the gain settings are set to. This is not specifically documented by the chip manufacturer, but when we started to test preproduction units out, we dicovered the gap that we documented in the FAQ. Can you adjust your LO to compensate? My 2nd question is about the byte stream which will be send to the FCD for frequency setting.
I assume that within this control string not just the frequency is set, but also the FCD filter, preamp, phamtom volatge … will be set. Is there a documentation about the field description to be used? The parameters directly control the available settings on the tuner chip itself. There is a header file in there, FCHidCmd. Can you let me have some more information please?
What software and version s is it that is telling you that no FCD is detected? Hello everybody. I had a problem on my main PC running XP sp3 the dongle was not recognised as a sound card.
It seems that something modified the original directory. In fact comparing the two directories revealed that lots of modifications are made by the various programs i tried. Received the FCD today. Given this failure, I downloaded the source code, compiled it in Qt, fixed the warnings in the code unused variables in function calls, harmless but annoying and very bad practice , and get the same results.
Before I go digging into the source to try and figure it out, I should point out that the FCD is plugged into a powered hub — where, as I say, it works fine with the simple front end and Spectraview. Does anyone know if the Qt code handles other than the primary ports on a computer?
OK, never mind. Works once the FCd is upgraded to 18j. Sorry, but I need help. I can not do my FCD to work. It is not possible to start the setup. What to do? That is why you need the FCHid program. Good afternoon. How to transfer to an operating mode? I received the receiver at the end of May, but time to be engaged in it appeared just now. Tried to update, as it is described on a site. Usually if the device will not exit bootloader mode there is a hardware fault that occurs while starting up the firmware.
If you can email me a tracking number of the returned device, I will send a brand new replacement straight away. Hello Howard, I purchased the Funcube Dongle Pro about 3 months ago, at the time it was the latest ver 1. I have tried on and off since I purchased the above to get it working, without success I have reloaded the 18j firmware from you website and followed the instructions all loaded ok. The problem that I am encountering is that I cannot receive any radio frequency on it, the only thing I manage to get is on short bursts of packet radio which is very quiet, and when I changed frequency and set the new frequency all I get is a continuosly cw tones and telling me that the dongle is not there.
I have tried all bands with no success. As this was not cheap I would appreciate feed back on where to send this back to, in order for it to be checked out for any faults on it. Many thanks I would appreciate a reply. Neville G4ZTM. Hello Howard, I wonder how my Dongle is coming along, did you find any problems with it?
Or have you fixed it and despatched it back to me. I have been looking on my email to see if you had passed any comment, but as yet have not had any further emails from you. Hi Howard is it possible to buy a replacement sticker for the PRO? Cheers Gary 2e0lgz. Is it possible to put the extio here as people new to the dongles keep asking on the yahoo groups.
To download they need to join yahoo whereas here they only need solve a moderate maths puzzle. It seems stable. The old version for the pro has a bug I ought to fix. It is in the ini file reading. Subtle stupidity on my part.. I will go with typo. I will upload a corrected version presently. I will also bump it up to release 1. There are no other changes of note. The name provided in the examples hw:0 and others are Linux-style names. Are there any other unexpected quirks there?
Broadcast band should be about the same. Thanks for some figures to work on with. Works nice. Is that normal? The peak in the middle is due to DC offset and phase noise.
Thanks for reply on spurs. I am still baffled by the terminated noise floor. At best mine is dbm using the latest standard SW. I have noted a few posts with dbm or more. Am I missing something? Sorry it looks like I misunderstood your question. What OS are you using? Also what software are you using? The dB levels are all relative, but I agree, about to dB or so is a nice starting point. If you are seeing the spurs, as these are very low level, then I am sure that it is a software-side level setting thing.
Using w7 with a resetting of the recording level the spurs are just about gone and the noise floor runs dbm or so. The overall sensitivity is also better.
